This study examines methods for recognizing different classes of phones from accented speech based on voice onset time (VOT). These methods are tested on data from the Tball corpus of Los Angeles-area elementary school children [1]. The methods proposed and tested are: 1) to train models based on standard English VOT contrasts and then extract the VOT characteristics of the phones by measuring ...
A series of experiments was carded out to compare the extent of range effects in the phonetic ategorization. of voice onset ime (VOT} by speakers of Polish and of English, two languages which contrast different VOT categories. Results indicate that Poles are more prone to range effects than are Americans. For acoustic continua with appr•able numbers of prevoiced stimuli, monolingual Polish spea...
The Thermal Infrared Visual Object Tracking challenge 2016, VOT-TIR2016, aims at comparing short-term single-object visual trackers that work on thermal infrared (TIR) sequences and do not apply pre-learned models of object appearance. VOT-TIR2016 is the second benchmark on short-term tracking in TIR sequences. Results of 24 trackers are presented. For each participating tracker, a short descri...
This paper applies nonparametric and semiparametric methods to investigate the distribution of the value of travel time (VOT) from experimental binary choice data using minimal prior distributional assumptions. Using a large dataset, results indicate that the VOT is approximately distributed as lognormal within the range for which observations exist. This implies that the lognormal would be sui...
This study reports on an investigation into the voice onset time (VOT) patterns of the plosives /p b t d/ in a group of 30 children aged 7 (n = 10), 9 (n = 10) and 11 (n = 10) years. Equal numbers of girls and boys participated in the study. Each child named a series of letter objects to elicit /p b t d/ in a syllable onset position with a fixed vowel context. VOT data were examined for age, se...
Native speakers of Spanish with different amounts of experience with English classified stop-consonant voicing (/b/ versus /p/) across different speech accents: English-accented Spanish, native Spanish, and native English. While listeners with little experience with English classified target voicing with an English- or Spanish-like voice onset time (VOT) boundary, predicted by contextual VOT, l...
The influence of voice-onset time (VOT) and vowel-onset characteristics on the perception of the voicing contrast for initial plosive consonants was examined for hearing-impaired children, and normal-hearing children and adults. Listeners identified spoken 'DAD'--'TAD' stimuli controlled for VOT and vowel onset characteristics. Only six of 16 hearing-impaired children appropriately identified t...
This study reinvestigated the VOT values of the three Korean stops according to phonation type by taking factors such as age, place of articulation, syllable type, and speech rate into consideration. Specifically, Silva’s findings and implications (2006) were retested. Data were obtained from nine Seoul female speakers varying 20’, 40’s, and 50’s in terms of age. The results showed that there w...
This study explored effects of simultaneous use of late bilinguals’ languages on their second-language (L2) pronunciation. We tested (1) if bilinguals effectively inhibit the first language (L1) when simultaneously processing L1 and L2, (2) if bilinguals, like natives, imitate subphonemic variation, (3) if bilinguals’ imitation operates crosslinguistically, and (4) if imitation interacts with p...
SUMMARY The present study investigated the effect of tonal changes on voice onset time (VOT) between normal laryngeal (NL) and superior esophageal (SE) speakers of Mandarin Chinese. VOT values were measured from the syllables /pha/, /tha/, and /kha/ produced at four tone levels by eight NL and seven SE speakers who were native speakers of Mandarin. Results indicated that Mandarin tones were ass...
