Thus, 150 children aged 8-11 years old and 36 adults were audio-recorded when producing the plosives in minimal …This report presents a brief study into sex differences of speakers in the voice onset time of English plosives that are stressed in both word-initial and pre-vocalic positions. 36 isolated words were spoken by 5 men (age range 25 to 37 yr., M: 34.2 yr.) and 5 women speakers (age range 28 to 38 yr., M: 32.6 yr.) who were subjects.Analysis showed that the women speakers had on the average ...Voice Onset Time (VOT) is the duration of the period of time between the release of a plosive and the beginning of vocal fold vibration. This period is usually measured in milliseconds (ms). It is useful to distinguish at least three types of VOT which are shown in the schematic diagram below: Zero VOT: where the tion and voice onset time segmentation. We describe each of them in details in the following subsections.1 4.1. Word Segmentation In the problem of word segmentation we are provided with a speech utterance which contains a single word; our goal is to predict its start and end times. The ability to determine these timings is crucial to phonetic studies that …of voice-onset time (VOT). Voice-onset time is the period of time between the release of a stop consonant and the following vowel. In English the VOT of voiceless stops /p t k/ is considerably longer than in Spanish.

For example, the differences between b-p, d-t and g-k Voice onset time (VOT) is known to be a primary acoustic cue that differentiates voiced from voiceless stops in the world's languages. While much attention has been given to the sound change of Korean stops, little attention has been given to that of English stops. This study examines VOT of stop consonants as produced by English speakers in comparison to Korean speakers to see whether there ...

Acoustic correlates of articulatory strength were measured, including closure duration for /d/ and /t/, as well as voice onset time and burst energy for /t/. Our results show that closure duration increases cumulatively from syllable to intermediate phrase, while voice onset time and burst energy are not influenced by boundary strength.That 30-40 milliseconds between when the stop closure is released and the voicing begins is called the voice onset time or VOT. In English, voiceless stops in certain positions have a VOT of 30-40 milliseconds, so we say that they're aspirated. But voiced stops have a much shorter VOT, of about 0-10 milliseconds. ...

In order to investigate the plosive feature, the parameter of voice onset time (VOT), which is defined as the interval between the release of the oral occlusion for the plosive articulation and the onset of vocal fold vibration, is used to characterize the unaspirated plosive /t/ [14]. Wide-band spectrographic analysis shows the release point ...Duration of phonation, voice onset time, and coefficients of variation were computed and analyzed. It was shown that stutterers produced, even during nonstuttering periods under repetitive articulation, an enhanced variation of voice onset time and an increased variability for the duration of phonation associated with the production of the ...Voice onset time. The voice onset time (VOT) helps to measure the second language speaker’s proficiency by analysing the participants’ ability to detect distinctions between similar-sounding phonemes. VOT refers to "the time interval between the onset of the release burst of a stop consonant and the onset of periodicity from vocal fold ...English and Mandarin Chinese differ in the voice onset times (VOTs) of /b/ and /p/. Hence the way bilinguals perceive these sounds may show 'tuning' to the language-specific acoustic structure ...Effects of age of learning on voice onset time: categorical perception of Swedish stops by near-native L2 speakers.

VOT identification curves revealed category boundaries that corresponded to Hebrew ...Voice onset time (VOT), the temporal difference between a stop closure release and the onset of vocal fold vibration, is an effective acoustic parameter in differentiating stop consonants in many languages (Lisker and Abramson, 1964; Cho and Ladefoged, 1999; among others). Along the VOT dimension, stop categories can be roughly classified as ...of voice-onset time (VOT). Voice-onset time is the period of time between the release of a stop consonant and the following vowel. In English the VOT of voiceless stops /p t k/ is considerably longer than in Spanish. Lisker and Abramson (1964) measured the mean VOT durations of word- in duration before the onset of vowel voicing is call Voice Onset Time (VOT). Aspirated stops are said to have long-lag VOT, while unaspirated stops are said to have short-lag VOT. These durations are quantified by marking the release of the closure as the VOT-on point, or the zero-point, and the onset of voicing as the VOT-off point.

This study investigates the integration of word-initial fundamental frequency (F0) and voice-onset-time (VOT) in stop voicing categorization for adult listeners with normal hearing (NH) and unilateral cochlear implant (CI) recipients utilizing a bimodal hearing configuration [CI + contralateral hearing aid (HA)].
