PURPOSE To develop a real-time imaging technique that allows for simultaneous visualization of vocal tract shaping in multiple scan planes, and provides dynamic visualization of complex articulatory features. MATERIALS AND METHODS Simultaneous imaging of multiple slices was implemented using a custom real-time imaging platform. Midsagittal, coronal, and axial scan planes of the human upper ai...

A model for multi-pitch analysis is extended into an iterative multi-pitch analysis and prediction (IMPAP) scheme. The method is efficient in finding harmonic complex tones, such as voiced speech signals, in a mixture of such signals and possible noise background. It can also be used to separate the signal into perceptually relevant speech components. The method may be used in applications rang...

The present paper investigates the automatic detection of word-initial glottalization phenomena (glottal stops and creaky voice) in German-accented English by means of HMMs. Glottalization of word-initial vowels can be very frequent in German-accented English, as well as in German. Detection and classification of glottalization phenomena is useful in order to obtain a pre-segmentation of speech...

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...

This contrastive study, in the first place, examined the generic structure and, in the second place, explored the face theory proposed by Arundale (2006) in 140 doctoral dissertation acknowledgments written by native speakers of Persian (NSP) and native speakers of English (NSE) in 7 disciplines representing soft sciences to find out what discourse genre components writers employ to articulate ...

We investigate the hypothesis that duration and spectral differences in vowels before voiceless versus voiced codas originate from a single source, namely the reorganization of articulatory gestures relative to one another in time. As a test case, we examine the American English diphthong /aɪ/, in which the acoustic manifestations of the nucleus /a/ and offglide /ɪ/ gestures are relatively easy...

Signal processing in current days is under studying. One of these studies focuses on speech processing. Speech signal have many important features. One of them is Voice Onset Time (VOT). This feature only appears in stop sounds. The human auditory system can utilize the VOT to differentiate between voiced and unvoiced stops like /p/ and /b/ in the English language. By VOT feature we can classif...

Abstract Research on Western Armenian (WA) has described it as having a contrast between voiceless aspirated stops and voiced (Fairbanks 1948; Vaux 1998; Baronian 2017). Since there is no monolingual community of WA, all speakers are part minority language community, also speak the majority language. The current study examines from two heritage communities WA: one in Lebanon, where Arabic, US, ...
