This paper introduces a new technique of multi-microphone processing which aims to provide features for the extraction of fundamental frequency and for the classification of voiced/unvoiced segments in distant-talking speech. A multichannel periodicity function (MPF) is derived from an adaptive weighting of normalized and compressed magnitude spectra. This function highlights periodic clues of ...

This paper investigates the performance of a silent speech interface (SSI) based on permanent-magnetic articulography (PMA) across several speakers. In a previously published study, the SSI was shown to be capable of distinguishing between voiced and unvoiced plosives ([b,p] and [d,t]) in data recorded from a single speaker; a surprising result in a system without access to speech acoustics. Th...

Data collected from Japanese and English showed that both phonetically fully voiced and (partially) devoiced allophones of /d/ have very similar perturbatory effect on the F0 of the following vowel. It is considered, therefore, that the phonetic voicing of /d/ (periodicity during the closure) i s not clearly correlated with lower levels of F0 on the following vowel. Although the F0 perturbation...

An experiment to explore the method realizing a concatenative Chinese TTS accommodating isolated English words is presented. The experiment was based on an existing concatenative Mandarin TTS system, developed in Motorola China Research Center. The experimental system employs an English word synthesizer based on the concatenation of speech segments stored in an English corpus. The original Engl...

The present study seeks to provide acoustic evidence of articulatory adjustments to initiate and sustain voicing during stops. First, using aerodynamic and acoustic data, it examines variations in the amplitude of voicing in phraseinitial voiced stops in Spanish and English and relates these variations to articulatory adjustments to preserve a low oral pressure and voicing. Second, a correlatio...

This paper explores the acoustic characteristics of English and Thai fricatives, uttered by native-Thai speakers. In the phonological systems, English has four pairs of voiceless-voiced fricatives, which appear initially, intervocalically, and finally. Thai, on the other hand, has only two initial voiceless fricatives. The results of this acoustic study revealed that the major acoustic cues of ...

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 ...

Building on the contemporary functional phonology, the present paper posits physical groundings in coda maximization. The four sorts of conditioning consonants that commonly undergo the syllabification stem from the articulations that preferentially affiliate to stressed syllable codas: contact of the tongue for the American English tap, no incompatibility for the British English glottal stop, ...

Our paper addresses the question of cross-linguistic similarities and differences in the articulatory patterns of plosives. An EPG investigation of the English and Norwegian plosives /t/ and /d/ shows a larger contact area between tongue and palate for /t/ than for /d/ in both languages. The investigation also shows a more laminal articulation, larger contact areas, for both plosives in Norwegi...

This paper investigated interdisciplinary attitudes within the English Language Teaching (ELT) department and across its boundaries, drawing upon case study research, conducted by means of questionnaires and follow up semi-structured interviews among ELT and non-ELT faculty in four Japanese colleges and universities in one prefecture. Three themes are argued as impacting upon the concept of int...
