Four groups of 10 subjects each (English and Spanish monolinguals, and two groups of Spanish/English bilinguals) produced Spanish or English sentences at speaking rates designated 'normal', 'slow', and 'fast'. Voice onset time (VOT) was measured in word-initial tokens of /p/ and /t/ found in sentence-initial, -medial, and -final words. The four groups produced comparable changes in sentence dur...

The covariation of onset f0 with voice onset time (VOT) was examined across and within phonological voicing categories in two languages, English and Spanish. The results showed a significant co-dependency between onset f0 and VOT across phonological voicing categories but not within categories, in both languages. Thus, English short lag and long lag VOT stops, which contrast phonologically, wer...

The ventral occipitotemporal cortex (vOT) is involved in the perception of visually presented objects and written words. The Interactive Account of vOT function is based on the premise that perception involves the synthesis of bottom-up sensory input with top-down predictions that are generated automatically from prior experience. We propose that vOT integrates visuospatial features abstracted ...

In order to determine whether small within-category differences in voice onset time (VOT) affect lexical access, eye movements were monitored as participants indicated which of four pictures was named by spoken stimuli that varied along a 0–40 ms VOT continuum. Within-category differences in VOT resulted in gradient increases in fixations to cross-boundary lexical competitors as VOT approached ...

OBJECTIVE To compare the voice onset time (VOT) differences of Korean stops in the initial and intervocalic positions between the aphasic patients with peculiarities of aspiration and a control group. METHOD We examined 15 aphasic patients (nine males, six females) who had suffered a stroke (average age 49.7 years) and 15 healthy controls (average age 47.4 years). An aphasia examination was m...

In English, voiced and voiceless syllable-initial stop consonants differ in both fundamental frequency at the onset of voicing (onset F0) and voice onset time (VOT). Although both correlates, alone, can cue the voicing contrast, listeners weight VOT more heavily when both are available. Such differential weighting may arise from differences in the perceptual distance between voicing categories ...

Title of Document: VOICE ONSET TIME IN INFANT-DIRECTED SPEECH AT TWO AGES Anna Synnestvedt, Master of Arts, 2010 Thesis Directed by: Dr. Nan Bernstein Ratner Department of Hearing and Speech Sciences Studies have reported differences between infant-directed speech (IDS) and adultdirected speech (ADS), suggesting that mothers adjust speech to their infants in ways that may help children process ...

Voice onset time (VOT) is defined as the time difference between the onset of the burst and the onset of voicing. When voicing begins preceding the burst, the stop is called prevoiced, and the VOT is negative. When voicing begins following the burst the VOT is positive. While most of the work on automatic measurement of VOT has focused on positive VOT mostly evident in American English, in many...

This study examines the influence of lexical tone on voice onset time (VOT) in Mandarin and Hakka spoken in Taiwan. The examination of VOT values for Mandarin and Hakka word-initial stops /p, t, k, p, t, k/ followed by three vowels /i, u, a/ in different lexical tones revealed that lexical tone has significant influence on the VOT values for stops. The results are important as they suggest that...

The production of voice-onset time (VOT) was studied in a group of Spanishand English-learning subjects at 1 and 2 years of age. Voiceonset time of initial stop consonants from canonical utterances was measured oscillographically. At one year no significant difference in VOT production was found between Spanish and English learners at any place of articulation. Mean VOT values for infants fell ...
