Articulation characteristics of particular phonemes can provide cues to distinguish accents in spoken English. For example, as shown in Arslan and Hansen (1996, 1997), Voice Onset Time (VOT) can be used to classify mandarin, Turkish, German and American accented English. Our goal in this study is to develop an automatic system that classifies accents using VOT in unvoiced stops. VOT is an impor...

A Chinese aspiration is generally considered to be very difficult for Japanese students to reproduce. We measured the voice on set time (VOT) and mean breathing power during VOT, as evaluation parameters, of diphthong sounds of the labial of pai[p'ai], pao[p'ao], pei[p'ei], and pie[p'iε] and diphthong sounds of the alveolar of tai[t'ai], tao[t'ao], tie[t'iε], and tou[t'ou] in Chinese aspiration...

Voice onset times ~VOT! and burst frequencies of two aspirated ~i.e., /k /, /g/) and two unaspirated ~i.e., /k/, /g/! Gujarati velar stop consonants were investigated in an effort to provide characteristic acoustic information. Stop consonants in a monosyllabic vowel–consonant–vowel ~VCV! production were obtained from eight native speakers of Gujarati. Differences in mean VOT and burst frequenc...

In this report, we present the details of our submission and the evaluation results on both the visual object tracking (VOT) 2015 and the thermal infrared visual object tracking (VOT-TIR) 2015 challenges. The goal of these challenges is to compare short-term model-free single-object trackers, and serve as the de factor state-of-the-art evaluation platform for visual object tracking. In particul...

We design a coordination mechanism for truck drivers that uses pricing-and-routing schemes can help alleviate traffic congestion in general transportation network. consider the user heterogeneity Value-Of-Time (VOT) by adopting multi-class model with stochastic Origin-Destination (OD) demands drivers. The main characteristic of is coordinator asks to declare their desired OD pair and pick indiv...

This study examined whether Spanish-English bilinguals are able to fully differentiate Spanish and English /t/ according to voice-onset time (VOT) if they learn English as a second language (L2) in early childhood. In experiment 1, VOT was measured in Spanish words spoken by Spanish monolinguals, in English words spoken by English monolinguals, and in Spanish and English words spoken by bilingu...

In order to understand speech, listeners must weight and combine multiple acoustic cues. For example, voice onset time (VOT) is a reliable cue to stop consonant voicing, while onset F0 provides information, but is much less reliable. Consequently, we would expect listeners to weight VOT higher than F0. This is the pattern observed for most listeners. However, these cue weights also change over ...

Voice onset time (VOT) is a key temporal feature in spoken language. There is some evidence to suggest that there are sex differences in VOT patterns. The cause of these sex differences could be attributed to sexual dimorphism of the vocal apparatus. There is also some evidence to suggest that phonetic sex differences could also be attributed to learned stylistic and linguistic factors. This st...

Talkers differ greatly in the acoustic realization of speech sounds, a source of signal variation that must be overcome by human and machine listeners. The present study examined talker variability in voice onset time (VOT) across the six word-initial stop consonant categories (/ptkbdg/) of American English. Employing a large corpus of productions from more than 100 speakers, we replicated prev...

This study investigated how the degree of attention modulates English learners’ perception of Korean stop contrasts. The contributions of VOT and F0 in perceiving Korean stops were examined while availability of attentional resources was manipulated using a dual-task paradigm. Results demonstrated the attentional modulation in the use of VOT, but not in F0: under less attention, the contributio...
