Post-vocalic stop consonants in Mebengokre (Northern Jê, Brazil): A preliminary investigation
نویسندگان
چکیده
This paper presents the first acoustic phonetic investigation of Mebengokre, a Jê language spoken in the brazilian Amazon. Our focus lies in one conspicuous property of this language’s phonetic structure: the frequent occurrence of unreleased stops in post-vocalic position. Based on auditory impressions from the field and on theoretical considerations we expected to observe variation in vowel duration and patterns of formant transition (especially F2) as a function of the presence or absence of a following consonant. Vowels in CVC syllables were found to be significantly shorter than those in CV, while formant patterns (F2 offset transitions) are less reliable in distinguishing the two conditions, due, arguably, to the highly context-dependent nature of this parameter. Finally, a large majority of the tokens analyzed contained no stop release burst that could be identified from the inspection of waveforms.

A Preliminary Epg Study of Stop Consonants in Arrernte
The Australian Aboriginal language Arrernte has four coronal consonants in the stop, nasal and lateral series. This paper presents EPG data for the four coronal stops of Arrernte in inter-vocalic context for one female speaker of the language. Results show comparatively little variability in the laminal articulations, and comparatively greater variability in the apical articulations. An interes...
متن کاملPhonetically enriched labeling in unit selection TTS synthesis
Unit selection techniques have improved the quality of textto-speech (TTS) synthesis. However, mistakes which had been less noticeable previously in poorer quality synthetic speech become very noticeable in more natural-sounding synthetic speech. Many problems appear to be caused by mismatches between phones requested by the TTS frontend and phones selected from the labeled speech inventory. Gi...
متن کاملProduction and perception of Vietnamese final stop consonants /p, t, k/
The bursts and voiced formant transitions are well known as separate cues to the place of articulation of initial stop consonant. The Vietnamese presents three final voiceless stop consonants /p, t, k/ without bursts. It is an opportunity to study these final stop consonants and to compare their characteristics with those of the corresponding initial stop consonants. This paper analyses these f...
متن کاملContrastive breathiness across consonants and vowels: A comparative study of Gujarati and White Hmong
Gujarati and White Hmong are among a small handful of languages known to maintain a phonemic contrast between breathy and modal voice across both obstruents and vowels. Given that breathiness on stop consonants is realized as a breathy-voiced aspirated release into the following vowel, how is consonant breathiness distinguished from vocalic breathiness, if at all? We examine acoustic and electr...
متن کاملA Simple Hybrid Acoustic / Morphologically-Constrained Technique for the Synthesis of Stop Consonants in Various Vocalic Contexts
The predominant way to synthesize stop consonants is currently to use an articulatory model controlled by vocal tract parameters. We propose a new method to make this synthesis in various vocalic contexts. To generate the formant transitions, the basic principle is to apply an opening function on the (equal-length section) area function derived from the linear predictive (LP) model of speech si...
