The purpose of this study was to examine the impact of place of articulation on voice onset time (VOT) of Persian initial plosive productions for Iranian cleft palate children. Fifteen cleft palate children and twenty children born without cleft were asked to produce seven words in CVC syllabic pattern. The initial consonant of the syllable was a plosive; the vowel was the close, front vowel /i...

A set of three perceptual experiments is described. These experiments were designed to provide identification scores on CV sequences for French. Original stimuli were augmented with acoustic “monsters” where burst were excised or replaced. The first identification task shows that information carried by vocalic transitions can be overwritten by burst information. The importance of this phenomeno...

The treatment of tuberculosis requires daily intake of multiple medications for between 6 months and 2 years, or more [1, 2]. This long duration predisposes to the interruption of medications with the risk of the emergence of drug resistance, death, disease persistence and continued transmission of tuberculosis in the community. Directly observed treatment, together with patient support, has be...

We present an architecture for locating phonetic events accurately in time, and for measuring time differences between nearby events, using Voice Onset Time (VOT) as a case study. Although VOT remains a central concern in the field, phoneticians' VOT measurements generally continue to rely on human judgment. This requires significant labor, makes even large laboratory experiments onerous, and p...

This study examined whether native speakers of Japanese could attend to critical acoustic features while identifying lenis and aspirated among Korean alveolar stops. Most Japanese participants had studied Korean for more than one year at a university language center in Korea. Native speakers of Korean were also tested with the same task for comparison. Korean participants discriminated the phon...

Unlike most languages that are written using a single script, Japanese uses multiple scripts including morphographic Kanji and syllabographic Hiragana and Katakana. Here, we used functional magnetic resonance imaging with dynamic causal modeling to investigate competing theories regarding the neural processing of Kanji and Hiragana during a visual lexical decision task. First, a bilateral model...

The human voice originates from oscillations of the vocal folds in the larynx. The duration of the voice onset (VO), called the voice onset time (VOT), is currently under investigation as a clinical indicator for correct laryngeal functionality. Different analytical approaches for computing the VOT based on endoscopic imaging were compared to determine the most reliable method to quantify autom...

Auditory evoked potential (AEP) correlates of the neural representation of stimuli along a /ga/-/ka/ and a /ba/-/pa/ continuum were examined to determine whether the voice-onset time (VOT)-related change in the N1 onset response from a single to double-peaked component is a reliable indicator of the perception of voiced and voiceless sounds. Behavioral identification results from ten subjects r...

This study tests the hypothesis that temporal response patterns in primary auditory cortex are potentially relevant for voice onset time (VOT) encoding in two related experiments. The first experiment investigates whether temporal responses reflecting VOT are modulated in a way that can account for boundary shifts that occur with changes in first formant (F1) frequency, and by extension, conson...
