Voice onset time variation in stop consonant to vowel transitions
… suggest that speech duration is dependent on voice onset time (VOT) variation among the participants. This study could serve as a basis to encourage further research analyzing neuromotor and physiological articulatory control, which could lead to interventional treatment for individuals having …

Aspiration in Chinese
… of acoustical characteristics of the voice onset time and the lengths of the syllable, a constant ratio model has been proposed to describe the timing relationships among the elements within a syllable. The perceptual experiment tested the cues of aspiration by deleting the portion of …

Harðhljóð og linhljóð: Um aðröddunartíma í íslensku, sænsku og búlgörsku
Voice Onset Time (VOT) is the time between the release of a stop consonent and the onset of voicing (vibrations in the vocal cords). This time is measured in ms and is negative for voiced stops and positive for unvoiced stops. VOT of +75ms and more is considered to indicated an aspirated stop. This …

Perception and analysis of Spanish accents in English speech
… speakers: intonation, vowel length, stress, voice onset time (VOT), or segmental accuracy. Nineteen native English speaking listeners rated speech samples from 7 native English speakers and 15 native Spanish speakers for comprehensibility and degree of foreign accent. The speech samples were …

The Effects of Deep Brain Stimulation on the Speech of Patients with Parkinson's Disease
… stop gap duration, alternating motion rate, and voice onset time were within normal limits for most participants across both stimulation conditions.

Frequency, Attention, and Phonetic Characteristics that Influence the Right-Ear Advantage for Speech Perception
… noise, and phonetic properties of stimuli, viz., voice onset time (VOT) and place of articulation (POA). Participants heard monosyllabic rhyming words from the Halwes (1990) Fused Dichotic Word Test and were instructed to attend to the left or right ear, or to divide attention equally. Stimuli in …

Stop production in Spanish-English bilingual children
… and compared crosslinguistically. Spanish voiceless stops have shorter voice onset time values than English voiceless stops, and Spanish voiced stops vary allophonically to approximants, a process that does not occur in English. Because previous child bilingual language acquisition studies …

Neurophysiologic and Behavioral Measures of Phonetic Perception in Adult Second Language Speakers of Spanish
… consonant-vowel (CV) stimuli that differed in voice onset time (VOT) from -50 to 30 ms VOT (/ba/ to /pa/). The -50 ms VOT stimulus was paired with each of the others to form stimulus pairs with varying degrees of acoustic difference. Behavioral data showed that L2 listeners of Spanish perceived …

The Acquisition of English stops by Saudi L2 Learners
Researchers have studied voice onset time (VOT) in a number of languages but there is a scarcity of research on the acquisition of VOT of English, particularly by adult Saudi learners, and on the VOT of Saudi Arabic. The current study aims to fill these gaps. At the same time, we aimed to assess …

Interactive Development Of F0 As An Acoustic Cue For Korean Stop Contrast
… have been phonetically differentiated by Voice Onset Time (VOT), but with a tonogenetic sound change in progress, the role of fundamental frequency (F0) has been amplified for distinguishing between Korean stop contrasts with the loss of VOT differentiation in young adults’ production. The …

The perceptual basis of long-distance laryngeal restrictions
… may pattern together because they share long voice onset time. It is shown that defining laryngeally marked stops based on their language specific auditory properties correctly accounts both for ejective-aspirate interactions in Quechua and also for the interaction between ejectives and …

A Comparative Variationist Analysis of Phonetic Variation and Change in Toronto Heritage Tagalog
… phonetic variables are examined: the F2 of /u/, voice onset time (VOT) of /p t k/, and the realization of /r/. Inter-group comparisons and multivariate analyses reveal distinctive patterns. Focusing on Heritage Tagalog, results demonstrate that the F2 of /u/ exhibits stable variation whereas the …

L2 Phonetic Detail in L1 Lexical Processing
… task: controlled stimuli with resynthesized VOT (voice onset time) in word onset, and naturally produced English-accented Spanish. L1 Spanish L2 English bilinguals are neither producers nor frequent overhearers of English-accented Spanish, so it was hypothesized that they would show evidence of …

A cross-linguistic study of certain temporal features of speech in stuttering and nonstuttering children
… nonstop utterers. Experiment one investigated voice onset time (VOT) of word-initial voiced and voiceless bilabial and apical stop plosives in isolated eve nonsense syllables. The VOTs were measured from oscilloscopic displays. Nonparametric statistical treatment identified certain trends in …

Perceptual and acoustic features of speech in individuals with Down syndrome and their impact on speech intelligibility
… the slope of the second formant of /ɑ/ and the voice onset time of /d/ were the strongest acoustic predictors of speech intelligibility for the speakers with DS. Study 3 investigated how language ability impacted on speech intelligibility for the speakers with DS. Regression analysis was used to …
