Fulltext Acoustic change complex in background noise: phoneme level and timing effects

Billings CJ, Grush LD, Maamor N

Physiol Rep, 2017 Nov;5(20).
PMID: 29051305 DOI: 10.14814/phy2.13464

The effects of background noise on speech-evoked cortical auditory evoked potentials (CAEPs) can provide insight into the physiology of the auditory system. The purpose of this study was to determine background noise effects on neural coding of different phonemes within a syllable. CAEPs were recorded from 15 young normal-hearing adults in response to speech signals /s/, /ɑ/, and /sɑ/. Signals were presented at varying signal-to-noise ratios (SNRs). The effects of SNR and context (in isolation or within syllable) were analyzed for both phonemes. For all three stimuli, latencies generally decreased and amplitudes generally increased as SNR improved, and context effects were not present; however, the amplitude of the /ɑ/ response was the exception, showing no SNR effect and a significant context effect. Differential coding of /s/ and /ɑ/ likely result from level and timing differences. Neural refractoriness may result in the lack of a robust SNR effect on amplitude in the syllable context. The stable amplitude across SNRs in response to the vowel in /sɑ/ suggests the combined effects of (1) acoustic characteristics of the syllable and noise at poor SNRs and (2) refractory effects resulting from phoneme timing at good SNRs. Results provide insights into the coding of multiple-onset speech syllables in varying levels of background noise and, together with behavioral measures, may help to improve our understanding of speech-perception-in-noise difficulties.

Acoustic characteristics of vowels by normal Malaysian Malay young adults

Ting HN, Chia SY, Abdul Hamid B, Mukari SZ

J Voice, 2011 Nov;25(6):e305-9.
PMID: 21429707 DOI: 10.1016/j.jvoice.2010.05.007

The acoustic characteristics of sustained vowel have been widely investigated across various languages and ethnic groups. These acoustic measures, including fundamental frequency (F(0)), jitter (Jitt), relative average perturbation (RAP), five-point period perturbation quotient (PPQ5), shimmer (Shim), and 11-point amplitude perturbation quotient (APQ11) are not well established for Malaysian Malay young adults. This article studies the acoustic measures of Malaysian Malay adults using acoustical analysis. The study analyzed six sustained Malay vowels of 60 normal native Malaysian Malay adults with a mean of 21.19 years. The F(0) values of Malaysian Malay males and females were reported as 134.85±18.54 and 238.27±24.06Hz, respectively. Malaysian Malay females had significantly higher F(0) than that of males for all the vowels. However, no significant differences were observed between the genders for the perturbation measures in all the vowels, except RAP in /e/. No significant F(0) differences between the vowels were observed. Significant differences between the vowels were reported for all perturbation measures in Malaysian Malay males. As for Malaysian Malay females, significant differences between the vowels were reported for Shim and APQ11. Multiethnic comparisons indicate that F(0) varies between Malaysian Malay and other ethnic groups. However, the perturbation measures cannot be directly compared, where the measures vary significantly across different speech analysis softwares.

Acquisition of Malay word recognition skills: lessons from low-progress early readers

Lee LW, Wheldall K

Dyslexia, 2011 Feb;17(1):19-37.
PMID: 21241030 DOI: 10.1002/dys.421

Malay is a consistent alphabetic orthography with complex syllable structures. The focus of this research was to investigate word recognition performance in order to inform reading interventions for low-progress early readers. Forty-six Grade 1 students were sampled and 11 were identified as low-progress readers. The results indicated that both syllable awareness and phoneme blending were significant predictors of word recognition, suggesting that both syllable and phonemic grain-sizes are important in Malay word recognition. Item analysis revealed a hierarchical pattern of difficulty based on the syllable and the phonic structure of the words. Error analysis identified the sources of errors to be errors due to inefficient syllable segmentation, oversimplification of syllables, insufficient grapheme-phoneme knowledge and inefficient phonemic code assembly. Evidence also suggests that direct instruction in syllable segmentation, phonemic awareness and grapheme-phoneme correspondence is necessary for low-progress readers to acquire word recognition skills. Finally, a logical sequence to teach grapheme-phoneme decoding in Malay is suggested.

MyJurnal

The study aims to identify an inventory of vowel phonemes of Melanau Rajang dialect in Belawai under the administration of Tanjung Manis District, Sarawak. This study is a field survey using interview methods to obtain data. A total 250 Swadesh list (Samarin, 1967) are used as a guide for data collection. In this study, two infotmants of different genders aged between 40 and 60 years old were selected based on criteria of informant selections according to Asmah Haji Omar (2001). In analysis data, qualitative method is used based on structural approaches. The findings show that there are eight (8) vowel phonemes have been identified; four (4) front vowels [i, e, ε, a]; one (1) central vowel [ə]; and three (3) back vowels [u, o, ɔ]. Besides that, the distribution/alternation of all vowel phonemes of Melanau Rajang dialect in Belawai are also discussed in this study. The findings also indicate that active vowel phonemes are vowels [a, i, u], while inactive vocal phonemes are vowels [ɔ, o, ε, ə, e].

Arabic phoneme-grapheme correspondence by non-native, deaf children with cochlear implants and normal hearing children

Anis FN, Umat C, Ahmad K, Abdul Hamid B

Cochlear Implants Int, 2022 Nov;23(6):347-357.
PMID: 36005236 DOI: 10.1080/14670100.2022.2114583

OBJECTIVE: This study aimed to compare the error patterns of Arabic phoneme-grapheme correspondence by a group of Malay children with cochlear implants (CIs) and normal hearing (NH) and the effects of the visual graphical features of Arabic graphemes (no-dot, single-dot, and multiple-dots) on the phoneme-grapheme correspondence.
METHODS: Participants were matched for hearing age (Mean, M = 7 ± 1.03 years) and duration of exposure to Arabic sounds (M = 2.7 ± 1.2 years). All 28 Arabic phonemes were presented through a loudspeaker and participants pointed to the graphemes associated with the presented phonemes.
RESULTS: A total of 336 and 616 tokens were collected for six children with CI and 11 NH children for each task, i.e., phonemes repetition and phoneme-grapheme correspondence. Both groups found it easier to repeat phonemes than the phoneme-grapheme correspondence. The children with CIs showed more confusion ([ظ, ز, ذ, ض, خ, ب, ه, س, ع, & ث] >10% correct scores) in phoneme-grapheme correspondence than the NH children ([ظ:14%] and [ث: 27%]). There was a significant interaction (p = 0.001) among the three visual graphical features and hearing status (CI and NH).
CONCLUSION: Our results infer that non-native Malay children with CIs and NH use different strategies to process the Arabic graphemes' visual features for phoneme-grapheme correspondence.

Assessing bilingual Chinese-English young children in Malaysia using language sample measures

Ooi CC, Wong AM

Int J Speech Lang Pathol, 2012 Dec;14(6):499-508.
PMID: 23039126 DOI: 10.3109/17549507.2012.712159

One reason why specific language impairment (SLI) is grossly under-identified in Malaysia is the absence of locally- developed norm-referenced language assessment tools for its multilingual and multicultural population. Spontaneous language samples provide quantitative information for language assessment, and useful descriptive information on child language development in complex language and cultural environments. This research consisted of two studies and investigated the use of measures obtained from English conversational samples among bilingual Chinese-English Malaysian preschoolers. The research found that the language sample measures were sensitive to developmental changes in this population and could identify SLI. The first study examined the relationship between age and mean length of utterance (MLU(w)), lexical diversity (D), and the index of productive syntax (IPSyn) among 52 typically-developing (TD) children aged between 3;4-6;9. Analyses showed a significant linear relationship between age and D (r = .450), the IPsyn (r = .441), and MLU(w) (r = .318). The second study compared the same measures obtained from 10 children with SLI, aged between 3;8-5;11, and their age-matched controls. The children with SLI had significantly shorter MLU(w) and lower IPSyn scores than the TD children. These findings suggest that utterance length and syntax production can be potential clinical markers of SLI in Chinese-English Malaysian children.

Consonant acquisition in the Malay language: a cross-sectional study of preschool aged Malay children

Phoon HS, Abdullah AC, Lee LW, Murugaiah P

Clin Linguist Phon, 2014 May;28(5):329-45.
PMID: 24446796 DOI: 10.3109/02699206.2013.868517

To date, there has been little research done on phonological acquisition in the Malay language of typically developing Malay-speaking children. This study serves to fill this gap by providing a systematic description of Malay consonant acquisition in a large cohort of preschool-aged children between 4- and 6-years-old. In the study, 326 Malay-dominant speaking children were assessed using a picture naming task that elicited 53 single words containing all the primary consonants in Malay. Two main analyses were conducted to study their consonant acquisition: (1) age of customary and mastery production of consonants; and (2) consonant accuracy. Results revealed that Malay children acquired all the syllable-initial and syllable-final consonants before 4;06-years-old, with the exception of syllable-final /s/, /h/ and /l/ which were acquired after 5;06-years-old. The development of Malay consonants increased gradually from 4- to 6 years old, with female children performing better than male children. The accuracy of consonants based on manner of articulation showed that glides, affricates, nasals, and stops were higher than fricatives and liquids. In general, syllable-initial consonants were more accurate than syllable-final consonants while consonants in monosyllabic and disyllabic words were more accurate than polysyllabic words. These findings will provide significant information for speech-language pathologists for assessing Malay-speaking children and designing treatment objectives that reflect the course of phonological development in Malay.

Contributions of phonological awareness, phonological short-term memory, and rapid automated naming, toward decoding ability in students with mild intellectual disability

Soltani A, Roslan S

Res Dev Disabil, 2013 Mar;34(3):1090-9.
PMID: 23314249 DOI: 10.1016/j.ridd.2012.12.005

Reading decoding ability is a fundamental skill to acquire word-specific orthographic information necessary for skilled reading. Decoding ability and its underlying phonological processing skills have been heavily investigated typically among developing students. However, the issue has rarely been noticed among students with intellectual disability who commonly suffer from reading decoding problems. This study is aimed at determining the contributions of phonological awareness, phonological short-term memory, and rapid automated naming, as three well known phonological processing skills, to decoding ability among 60 participants with mild intellectual disability of unspecified origin ranging from 15 to 23 years old. The results of the correlation analysis revealed that all three aspects of phonological processing are significantly correlated with decoding ability. Furthermore, a series of hierarchical regression analysis indicated that after controlling the effect of IQ, phonological awareness, and rapid automated naming are two distinct sources of decoding ability, but phonological short-term memory significantly contributes to decoding ability under the realm of phonological awareness.

Cross-linguistic transfer of phonological skills: a Malaysian perspective

Gomez C, Reason R

Dyslexia, 2002 Jan-Mar;8(1):22-33.
PMID: 11990222

This study examined the phonological and reading performance in English of Malaysian children whose home language was Bahasa Malaysia (BM). A sample of 69 Malaysian Standard Two pupils (aged 7-8 years) was selected for the study. Since commencing school at the age of 6 years, the children had been learning to read in BM and had subsequently also been learning to read in English for some 12 months. The study was part of a larger scale research programme that fully recognized the limitations of tests that had not been developed and standardized in Malaysia. Nevertheless, as a first step to developing such tests, a comparison with existing norms for the Phonological Assessment Battery (PhAB) and the Wechsler Objective Reading Dimension (WORD) was undertaken in relation to information about the children's L1 and L2 language competencies. Results showed that the children's performance on PhAB was at least comparable to the UK norms while, not surprisingly, they fared less well on WORD. The results are discussed in terms of L1 and L2 transfer, whereby the transparency of written BM and the structured way in which reading is taught in BM facilitates performance on phonological tasks in English. This has implications for identifying children with phonologically based reading difficulties.

Fulltext Differential coding of perception in the world's languages

Majid A, Roberts SG, Cilissen L, Emmorey K, Nicodemus B, O'Grady L, et al.

Proc Natl Acad Sci U S A, 2018 Nov 06;115(45):11369-11376.

Is there a universal hierarchy of the senses, such that some senses (e.g., vision) are more accessible to consciousness and linguistic description than others (e.g., smell)? The long-standing presumption in Western thought has been that vision and audition are more objective than the other senses, serving as the basis of knowledge and understanding, whereas touch, taste, and smell are crude and of little value. This predicts that humans ought to be better at communicating about sight and hearing than the other senses, and decades of work based on English and related languages certainly suggests this is true. However, how well does this reflect the diversity of languages and communities worldwide? To test whether there is a universal hierarchy of the senses, stimuli from the five basic senses were used to elicit descriptions in 20 diverse languages, including 3 unrelated sign languages. We found that languages differ fundamentally in which sensory domains they linguistically code systematically, and how they do so. The tendency for better coding in some domains can be explained in part by cultural preoccupations. Although languages seem free to elaborate specific sensory domains, some general tendencies emerge: for example, with some exceptions, smell is poorly coded. The surprise is that, despite the gradual phylogenetic accumulation of the senses, and the imbalances in the neural tissue dedicated to them, no single hierarchy of the senses imposes itself upon language.

Digital noise reduction in hearing aids and its acoustic effect on consonants /s/ and /z/

Chong FY, Jenstad LM

Med J Malaysia, 2018 12;73(6):365-370.
PMID: 30647205

INTRODUCTION: Modulation-based noise reduction (MBNR) is one of the common noise reduction methods used in hearing aids. Gain reduction in high frequency bands may occur for some implementations of MBNR and fricatives might be susceptible to alteration, given the high frequency components in fricative noise. The main objective of this study is to quantify the acoustic effect of MBNR on /s, z/.
METHODS: Speech-and-noise signals were presented to, and recorded from, six hearing aids mounted on a head and torso simulator. Test stimuli were nonsense words mixed with pink, cafeteria, or speech-modulated noise at 0 dB SNR. Fricatives /s, z/ were extracted from the recordings for analysis.
RESULTS: Analysis of the noise confirmed that MBNR in all hearing aids was activated for the recordings. More than 1.0 dB of acoustic change occurred to /s, z/ when MBNR was turned on in four out of the six hearing aids in the pink and cafeteria noise conditions. The acoustics of /s, z/ by female talkers were affected more than male talkers. Significant relationships between amount of noise reduction and acoustic change of /s, z/ were found. Amount of noise reduction accounts for 42.8% and 16.8% of the variability in acoustic change for /s/ and /z/ respectively.
CONCLUSION: Some clinically-available implementations of MBNR have measurable effects on the acoustics of fricatives. Possible implications for speech perception are discussed.

Emotional speech acoustic model for Malay: iterative versus isolated unit training

Mustafa MB, Ainon RN

J Acoust Soc Am, 2013 Oct;134(4):3057-66.
PMID: 24116440 DOI: 10.1121/1.4818741

The ability of speech synthesis system to synthesize emotional speech enhances the user's experience when using this kind of system and its related applications. However, the development of an emotional speech synthesis system is a daunting task in view of the complexity of human emotional speech. The more recent state-of-the-art speech synthesis systems, such as the one based on hidden Markov models, can synthesize emotional speech with acceptable naturalness with the use of a good emotional speech acoustic model. However, building an emotional speech acoustic model requires adequate resources including segment-phonetic labels of emotional speech, which is a problem for many under-resourced languages, including Malay. This research shows how it is possible to build an emotional speech acoustic model for Malay with minimal resources. To achieve this objective, two forms of initialization methods were considered: iterative training using the deterministic annealing expectation maximization algorithm and the isolated unit training. The seed model for the automatic segmentation is a neutral speech acoustic model, which was transformed to target emotion using two transformation techniques: model adaptation and context-dependent boundary refinement. Two forms of evaluation have been performed: an objective evaluation measuring the prosody error and a listening evaluation to measure the naturalness of the synthesized emotional speech.

Denture esthetics as defined by Glossary of prosthodontics terms the effect produced by a dental prosthesis that affects the beauty and attractiveness of the person. [1] Removable partial dentures (RPDs) are the widely accepted and treatment of choice for most cases as it is both effective and affordable. Partially edentulous treatment planning includes both esthetics and masticatory function. A prosthesis that is highly esthetic will improve patient's motivation and acceptance. It is a very wrong notion to expect that patients will tolerate unesthetic partial dentures because good masticatory capability has been achieved. Esthetics plays a vital role in the success of partial dentures, and the length and mobility of the patient's lips play a significant role in achieving it. [2] Patients with short lips or highly mobile lips pose problems as esthetics are compromised because most clasp arms, denture borders, and other components will show when the patient smiles or speaks. [3] RPDs can easily look artificial; hence, special emphasis should aim toward restoring function, phonetics, esthetics with a long-term benefits which requires meticulous attention during fabrication. This case reports is an esthetic clasp designed for a cast partial denture for a young girl for esthetic and function.

PMID: 22285457 DOI: 10.1016/j.jvoice.2011.08.008

The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay female children had higher formant frequencies than those of their male counterparts. However, no significant differences in all four formant frequencies were observed between the Malay male and female children in most of the vowels and age groups. Significant differences in all formant frequencies were found across the Malay vowels in both Malay male and female children for all age groups except for F4 in female children aged 12 years. Generally, the Malaysian Malay children showed a nonsystematic decrement in formant frequencies with age. Low levels of significant differences in formant frequencies were observed across the age groups in most of the vowels for F1, F3, and F4 in Malay male children and F1 and F4 in Malay female children.

Gender classification in children based on speech characteristics: using fundamental and formant frequencies of Malay vowels

Zourmand A, Ting HN, Mirhassani SM

J Voice, 2013 Mar;27(2):201-9.
PMID: 23473455 DOI: 10.1016/j.jvoice.2012.12.006

Speech is one of the prevalent communication mediums for humans. Identifying the gender of a child speaker based on his/her speech is crucial in telecommunication and speech therapy. This article investigates the use of fundamental and formant frequencies from sustained vowel phonation to distinguish the gender of Malay children aged between 7 and 12 years. The Euclidean minimum distance and multilayer perceptron were used to classify the gender of 360 Malay children based on different combinations of fundamental and formant frequencies (F0, F1, F2, and F3). The Euclidean minimum distance with normalized frequency data achieved a classification accuracy of 79.44%, which was higher than that of the nonnormalized frequency data. Age-dependent modeling was used to improve the accuracy of gender classification. The Euclidean distance method obtained 84.17% based on the optimal classification accuracy for all age groups. The accuracy was further increased to 99.81% using multilayer perceptron based on mel-frequency cepstral coefficients.

Fulltext High variability phonetic training in adaptive adverse conditions is rapid, effective, and sustained

Leong CXR, Price JM, Pitchford NJ, van Heuven WJB

PLoS One, 2018;13(10):e0204888.
PMID: 30300372 DOI: 10.1371/journal.pone.0204888

This paper evaluates a novel high variability phonetic training paradigm that involves presenting spoken words in adverse conditions. The effectiveness, generalizability, and longevity of this high variability phonetic training in adverse conditions was evaluated using English phoneme contrasts in three experiments with Malaysian multilinguals. Adverse conditions were created by presenting spoken words against background multi-talker babble. In Experiment 1, the adverse condition level was set at a fixed level throughout the training and in Experiment 2 the adverse condition level was determined for each participant before training using an adaptive staircase procedure. To explore the effectiveness and sustainability of the training, phonemic discrimination ability was assessed before and immediately after training (Experiments 1 and 2) and 6 months after training (Experiment 3). Generalization of training was evaluated within and across phonemic contrasts using trained and untrained stimuli. Results revealed significant perceptual improvements after just three 20-minute training sessions and these improvements were maintained after 6 months. The training benefits also generalized from trained to untrained stimuli. Crucially, perceptual improvements were significantly larger when the adverse conditions were adapted before each training session than when it was set at a fixed level. As the training improvements observed here are markedly larger than those reported in the literature, this indicates that the individualized phonetic training regime in adaptive adverse conditions (HVPT-AAC) is highly effective at improving speech perception.

Lexical analyses of the function and phonology of Papuan Malay word stress

Kaland C, Kluge A, van Heuven VJ

Phonetica, 2021 04 27;78(2):141-168.
PMID: 33892529 DOI: 10.1515/phon-2021-2003

The existence of word stress in Indonesian languages has been controversial. Recent acoustic analyses of Papuan Malay suggest that this language has word stress, counter to other studies and unlike closely related languages. The current study further investigates Papuan Malay by means of lexical (non-acoustic) analyses of two different aspects of word stress. In particular, this paper reports two distribution analyses of a word corpus, 1) investigating the extent to which stress patterns may help word recognition and 2) exploring the phonological factors that predict the distribution of stress patterns. The facilitating role of stress patterns in word recognition was investigated in a lexical analysis of word embeddings. The results show that Papuan Malay word stress (potentially) helps to disambiguate words. As for stress predictors, a random forest analysis investigated the effect of multiple morpho-phonological factors on stress placement. It was found that the mid vowels /ɛ/ and /ɔ/ play a central role in stress placement, refining the conclusions of previous work that mainly focused on /ɛ/. The current study confirms that non-acoustic research on stress can complement acoustic research in important ways. Crucially, the combined findings on stress in Papuan Malay so far give rise to an integrated perspective to word stress, in which phonetic, phonological and cognitive factors are considered.

Fulltext Listening while reading promotes word learning from stories

Valentini A, Ricketts J, Pye RE, Houston-Price C

J Exp Child Psychol, 2018 03;167:10-31.
PMID: 29154028 DOI: 10.1016/j.jecp.2017.09.022

Reading and listening to stories fosters vocabulary development. Studies of single word learning suggest that new words are more likely to be learned when both their oral and written forms are provided, compared with when only one form is given. This study explored children's learning of phonological, orthographic, and semantic information about words encountered in a story context. A total of 71 children (8- and 9-year-olds) were exposed to a story containing novel words in one of three conditions: (a) listening, (b) reading, or (c) simultaneous listening and reading ("combined" condition). Half of the novel words were presented with a definition, and half were presented without a definition. Both phonological and orthographic learning were assessed through recognition tasks. Semantic learning was measured using three tasks assessing recognition of each word's category, subcategory, and definition. Phonological learning was observed in all conditions, showing that phonological recoding supported the acquisition of phonological forms when children were not exposed to phonology (the reading condition). In contrast, children showed orthographic learning of the novel words only when they were exposed to orthographic forms, indicating that exposure to phonological forms alone did not prompt the establishment of orthographic representations. Semantic learning was greater in the combined condition than in the listening and reading conditions. The presence of the definition was associated with better performance on the semantic subcategory and definition posttests but not on the phonological, orthographic, or category posttests. Findings are discussed in relation to the lexical quality hypothesis and the availability of attentional resources.

Multilingual English-Mandarin-Malay phonological error patterns: An initial cross-sectional study of 2 to 4 years old Malaysian Chinese children

Lim HW

Clin Linguist Phon, 2018;32(10):889-912.
PMID: 29993293 DOI: 10.1080/02699206.2018.1459852

Child multilingual phonological errors are under-explored. Cross-linguistic studies suggest monolingual children make phonological errors that are subject to effects of language universality and ambient language characteristics. Bilingual Chinese children were observed to use not only typical, but also atypical phonological errors compared to monolingual peers acquiring similar languages. Atypical errors are a result of specific bilingual pair effects. Close-language-relatedness (Cantonese-Mandarin) is claimed to be responsible for the nonexistence of atypical errors in both languages, whilst distant-language-relatedness (Cantonese-English) is observed to cause atypical errors in both languages. The present novel cross-sectional study investigated phonological acquisition in three typologically distant languages: English-Mandarin-Malay by 64 multilingual Chinese children aged 2½-4½. The present research aimed to explore if multilingual Chinese children exhibit phonological errors which commensurate to that of monolingual and bilingual Chinese children acquiring similar languages as described in the literature. The single-word phonological test results revealed that the multilinguals exhibited typical and atypical phonological patterns which largely commensurate with the monolinguals and bilinguals. Similar to bilingual children, the multilingual children showed more atypical errors in English than in Mandarin, demonstrating effects of individual language irrespective of potential interaction with additional languages. The present result did not fully support the link between closeness in typology of languages and the absence of atypical errors. Rare atypical errors were found in Mandarin and Malay, two typologically different languages, and both were also interacting with English, another typologically different language. The present findings provided useful preliminary multilingual speech norms for the use of speech therapists.
