Although it has traditionally been described as contrasting ejective, voiceless aspirated, and voiced series of stops, there are no previous instrumental phonetic analyses of stop and affricate realizations in Kwak'wala. This study examines voice onset time in a single native speaker. VOT, the timing between the release of stop consonant closure and the onset of periodic voicing, has proven to ...

In most English accents vowel length is approximately 50% greater before a voiced consonant than before its voiceless cognate (the ‘Voicing Effect’). In Scottish English it is conditioned by the ‘Scottish Vowel Length Rule’. The lengthening environments of this rule overlap with those of the Voicing Effect. The phonetic details of the Scottish Vowel Length Rule and its relationship with the Voi...

Previous studies in interlanguage speech intelligibility benefit (ISIB) did not separate the effects of shared knowledge of L1 in non-native talkers from those of listeners through extensive exposure to accented L2 speech, which is crucial to the mechanism underlying ISIB. This preliminary study attempts to tease apart the two by comparing perception accuracy of Mandarin-accented English words ...

Abstract This paper presents a combined analysis of the perception and production study mixed language Light Warlpiri (Australia), which systematically combines elements Warlpiri, Kriol English. The results suggest that phonological inventory consists voiced voiceless series stops affricates, differentiated by Voice Onset Time (VOT) word-initially Constriction Duration (CD) medially, incorporat...

In this paper we propose features for automatic detection of voice bar, which is an essential component of voiced stop consonants, in continuous speech. The acoustic-phonetic and production based knowledge such as, the presence of voicing, low strength of excitation compared to other voiced phones and a predominant low-frequency spectral energy, are mapped onto a set of acoustic features that c...

Theories of laryngeal realism (Honeybone 2005, Iverson & Salmons 1995, Beckman et al. 2011) argue for a tight correspondence between a segment’s phonetic cues and the (laryngeal) phonological features that represent it. Consequently, the ‘p’/‘b’ contrast in French, expressed phonetically by vocal fold vibration during the stop closure is represented by a [voice] feature whereas the ‘p’/‘b’ cont...

In connection with the phonological distinction between voiced and voiceless sounds in languages, it can be observed that voiced sounds are relatively frequently devoiced, i.e. they are realized phonetically with little or no vocal fold vibration. This study investigated the devoicing of /v/ and /z/ in Standard Southern British English (SSBE) by means of a production experiment in which vocal f...

The two distinct sound sources comprising voiced frication, voicing and frication, interact. One effect is that the periodic source at the glottis modulates the amplitude of the frication source originating in the vocal tract above the constriction. Voicing strength and modulation depth for frication noise were measured for sustained English voiced fricatives using high-pass filtering, spectral...
