Voice onset time.

After reporting differences by sex and age in measures including stop closure and vowel duration, as well as voice onset time, Westrop suggested several possible explanations for the findings. These included slower speech production with increasing age, differences in oral cavity shape and size between the sexes, and genetic patterning …A key challenge in examining the interrelationship between these differences at various stages of production is the need for manual annotation of fine-grained properties of speech. We introduce a new method for automatically analysing voice onset time (VOT), a key phonetic feature indexing differences in sound systems cross-linguistically.Voice onset time (VOT) was measured for each stop consonant. A separate group of 20 listeners was then asked to identify the consonants produced by the LA, PA, and ES speakers. The VOT values of aspirated voiceless stop consonants from PA and ES were shorter than those from LA.In a series of experiments, we progressively explored the role of voice onset time (VOT) and potential secondary cues in adult labeling of stressed syllable-initial /b d p t/ produced by typically ...The voice is a highly salient cue in the perception of gender and an important analytic factor in both phonetic and sociophonetic analysis. Although we have a wealth of knowledge about the social construction of gender through language, gender differences in the voice are frequently treated as natural, direct products of sex differentiation. This …

voice-onset time (VOT) in phonetics, the brief instant that elapses between the initial movement of the speech organs as one begins to articulate a voiced speech sound and the vibration of the vocal cord. Voice-onset time has been the subject of research in adult and infant speech perception because of evidence that this continuous acoustic ...

The first part of the video measures the VOT of the English word "pie" /pai/ and ...Some effects of context on voice onset time in English stops. Language and speech, 10(1), 1–28. Lisker, L. (1972). Stop duration and voicing in English. Valdman, Papers in linguistics and ...

It is well-established that the formant transitions are the cues to differentiate the perceived place of articulation (POA) of a stop consonant, regardless of voice onset time (VOT). However, as shown in the acoustic analysis of utterances, it is also documented that stop consonants with different POAs have distinguished VOTs, in English and ...

As stated by Olson and Hayes-Harb (2019: 30), in both English and Arabic 'voice onset time [. . .] provides a robust acoustic cue to stop voicing contrast in initial position, with longer VOTs associated with voiceless stop consonants and shorter VOTs associated with voiced stop consonants.' We focus here on Standard Southern British ...Voice onset time (VOT) is an objective temporal acoustic parameter defined as the time between the release of the oral constriction for plosive production and the onset of vocal fold vibrations.Voice onset time (VOT) signifies the interval between consonant onset and the start of rhythmic vocal-cord vibrations. Differential perception of consonants such as /d/ and /t/ is categorical in American English, with the boundary generally lying at a VOT of 20–40 ms.We investigated various acoustic parameters: average fundamental sound frequency (F0), F0 range, F0 variance (SD), vowel formants (F1, F2, and F3), voice onset time (VOT) and H1-H2 (intensity difference between the first and the second harmonic frequencies, used to measure phonation type) in both languages. Our results revealed a significant ...The voice onset time can be a quantitative precise criterion for examining the movements of the tongue and can detect subtle movements of the tongue and lips, and speech language pathologists can better control the acoustic behavior by assessing this acoustic index Be. 5.2. Limitations and Weaknesses of the Study

Seminal acoustic work has described the impact of voice onset time (VOT) disturbances on voicing contrasts (Ackermann and Hertrich, 1997). Later research revealed similar findings, demonstrating that VOT abnormalities in speakers with Friedreich's ataxia (FA) resulted in voicing contrast errors (e.g., /d/ vs. /t/ or /s/ vs. /z/) ( Blaney and ...

Voice onset time When a stop consonant is produced, the air stream in the vocal tract is closed off and leads to a pressure build-up. The closure release leads to a burst of energy. A stop may

Purpose: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects bulbar functions including speech and voice. Voice onset time (VOT) was examined in speakers with ALS in early and late stages to explore the coordination of the articulatory and phonatory systems during speech production.Objectives: Voice onset time (VOT) for word-initial voiceless consonants in adductor spasmodic dysphonia (ADSD) and abductor spasmodic dysphonia (ABSD) patients were measured to determine (1) which acoustic measures differed from the controls and (2) whether acoustic measures were related to the pause or silence between the test word and the preceding word.Voice onset time (VOT) is an acoustic property of stop consonants that is commonly manipulated in studies of phonetic perception. This paper contains a thorough description of the "progressive ...This study aimed to investigate the relationship between (1) oscillatory onset-offset time across various approaches that use different measurement criteria and (2) oscillatory onset and offset times in vocally healthy young adults.Voice Onset Time (VOT) and onset f0 are known correlates of voicing distinctions in stops and both contribute to the production and perception of voicing (House & Fairbanks, 1953; Abramson ...

Evidence suggests that the fine motor coordinations required to maintain the articulatory-laryngeal adjustments represented by measures of voice onset time (VOT) should change as a function of normal aging. This descriptive study obtained measures of VOT in healthy elderly subjects as a basis for ...A cross-linguistic study of contact-induced change: Voice onset time across the generations. Part of. Multilingualism and Language Diversity in Urban Areas: Acquisition, identities, space, education. Edited by Peter Siemund, Ingrid Gogolin, Monika Edith Schulz and Julia Davydova. [ Hamburg Studies on Linguistic Diversity 1] 2013."Voice Onset Time" (VOT) is the time between when the stop is released and when the voicing of the following vowel begins. Measuring this time, which can be positive (say, for the English voiceless aspirated stop [t h]), around zero (for the English "voiced" stop /d/, or, more commonly, the voiceless unaspirated [t]), or negative (for fully voiced stops, where voicing starts before the stop is ...Voice onset time (VOT) in voiced and voiceless bilabial, alveolar and velar stops was compared between the two speech types. Results from two repeated measures analysis show longer VOTs in IDS than in ADS for alveolar and velar stops, as well as for /b/, but not for /p/. These results were stable across the six months.Voice onset time (VOT) signifies the interval between consonant onset and the start of rhythmic vocal-cord vibrations. Differential perception of consonants such as /d/ and /t/ is categorical in American English, with the boundary generally lying at a VOT of 20–40 ms.

open access • This collection marks 50 years of research on VOT and the voicing contrast in the world’s languages. • Nineteen languages are studied in 11 papers based on data obtained from over 270 speakers. • VOT continues to be a useful first estimate of laryngeal contrast in voicing across languages. •

The purpose of this paper was to investigate whether voice onset time differences occurred among speakers exhibiting four different types of dysarthria. Twenty dysarthric speakers were used as subjects: five spastic, five flaccid, five ataxic, and five hypokinetic. Repeated utterance tasks using /p lambda/, /t lambda/ and /k lambda/ were ...Relative timing of phonation start, e.g. Voice Onset Time (VOT) in plosives Fundamental frequency change within words, e.g. lexical tone Fundamental frequency change across utterances, e.g. intonation Voice quality changes contribute to turn-taking in dialogue. Voice also communicates the mood, mental state and health of the speaker:VOT，英文全称为voice onset time，中文有"嗓音起始时间"、"浊音起始时间"、"发声起始时间"、"声带震动起始时间"等各色缤纷的译法，大抵翻译仅襄阐释不做正名，称呼提举处多直引字母缩略形VOT。VOT的具体含义也不完全与字面吻合，其实际所指为：某一辅音从除阻的一刻到声带开始震动 ...Voice onset time, therefore, serves as a significant cue in distinguishing English voiced stops from their voiceless counterparts. Interestingly, voiceless stops in many Ghanaian indigenous languages appear to be weakly aspirated; they are perceived to be made with a very short voice onset time.Abstract.
