This paper investigates the production of wordinitial geminate consonants in Kelantan Malay with a focus on voiceless stops. It presents an acoustic phonetic analysis examining two acoustic parameters: closure duration and voice onset time (VOT). Evidence from a production experiment indicates that there is a clear durational contrast between word-initial voiceless geminate stops and their sing...

We examine the distinctive feature [voice] that separates the voiced from the unvoiced sounds for the case of stop consonants. We conduct acoustic-phonetic analyses on a large database and demonstrate the superior separability using a temporal measure (voice onset time; VOT) rather than spectral measures. We describe several algorithms to estimate the VOT automatically from continuous speech an...

Value-of-time (VOT) measures are valuable in a wide range of public transport policy and planning applications. However, VOT is a latent variable that cannot be measured directly. In this research, state-of-the-art econometric models are developed within a methodological framework that allows for the estimation of the VOT. Ordered and binary discrete choice models have been developed. Furthermo...

Five experiments monitored eye movements in phoneme and lexical identification tasks to examine the effect of within-category subphonetic variation on the perception of stop consonants. Experiment 1 demonstrated gradient effects along voice-onset time (VOT) continua made from natural speech, replicating results with synthetic speech (B. McMurray, M. K. Tanenhaus, & R. N. Aslin, 2002). Experimen...

"\Ye describe the representation of synthetic stopconsonants in a computational model of the mammalian dorsal cochlear nucleus. The speech stimuli have different values of voice-onset time (VOT) and are Iabelied by adult listeners as either /ga/ or /ka/, with a phonetic boundary at 44 ms VOT. The responses of the model's Type IV units to these stimuli also fall into two clear categories with a ...

VOT of English voiceless stops produced by L1dominant Czech-English bilinguals is examined in light of three hypotheses: (1) switching languages induces an immediate increase in L1 interference, (2) speakers experienced with switching languages show less immediate interference, and (3) interpreting induces greater interference than codeswitching. Eighteen bilinguals, trained vs beginning interp...

Voice onset time (VOT) is an important parameter of speech that denotes the time interval between consonant onset and the onset of low-frequency periodicity generated by rhythmic vocal cord vibration. Voiced stop consonants (/b/, /g/, and /d/) in syllable initial position are characterized by short VOTs, whereas unvoiced stop consonants (/p/, /k/, and t/) contain prolonged VOTs. As the VOT is i...

Consonant-Vowel (CV) construction is the most frequent syllable in Bangla. The present study examine the acoustic properties of Bangla four labial stop consonants [p, ph, b and bh] in the initial position in a consonant-vowel context with seven following vowels /ɔ, a, e, æ, i, u, o/. Bangla is a type of language that uses aspiration as an addition feature to distinguish phoneme. Bangla labial s...

This study is concerned with effects of age of onset (AO) of acquisition on the production of Voice Onset Time (VOT) among near-native L2 speakers. 41 L1 Spanish early and late learners of L2 Swedish, who had carefully been screened for their “nativelike” L2-proficiency, participated in the study. 8 native speakers of Swedish served as control group. Spectral analyses of VOT were carried out on...

Speech sounds are highly variable, yet listeners readily extract information from them and transform continuous acoustic signals into meaningful categories during language comprehension. A central question is whether perceptual encoding captures acoustic detail in a one-to-one fashion or whether it is affected by phonological categories. We addressed this question in an event-related potential ...
