The Effect of Syllable Structure on Bidirectional Coarticulation
نویسنده
چکیده
The goal of this research was to assess the effect of syllable structure and stop place on the strength of bidirectional coarticulation in VCV utterances. Frequencies of F2 transitions were measured at VC and CV boundaries in open (V.CV) and closed (VC.V) syllable forms in five speakers of American English. Medial stops varied across place and voicing (/bpdtgk/). Carryover and anticipatory coarticulation were measured by comparing the difference in F2 offsets of V1 (anticipatory) and F2 onsets of V2 (carryover) across four ‘fixed’ vowel (/i/, /e/, /u/, and / / ) and two ‘changing’ vowel contexts (/i/, / /). Results showed a significant syllable x coarticulation interaction with closed syllables favoring carryover and open syllables favoring anticipatory coarticulation. Only alveolar stops /dt/ failed to reveal greater anticipatory than carryover effects in open syllables.

Effects of consonant cluster syllabification on vowel-to-vowel coarticulation in English
This paper investigates how different syllable affiliations of intervocalic /st/ cluster affect vowel-to-vowel coarticulation in English. Very few studies have examined the effect of syllable structure on vowel-to-vowel coarticulation. Previous studies show that onset and coda consonants differ acoustically, articulatorily, perceptually and typologically. Onsets are stronger, more stable, more ...

In this paper, a new statistics-based pitch model for Mandarin speech is proposed. The model considers three major affecting factors on the syllable pitch contour, including lexical tone, prosodic state and inter-syllable coarticulation effect. The study emphasizes on the modeling of inter-syllable coarticulation effect. Interactive affections of neighboring tones and different inter-syllable c...

The finding of consistent tone-segment alignment in many languages in recent research raises questions about the temporal organization of speech sounds in general. In this paper we explore the possibility that tonal alignment patterns can lead to the discovery of basic principles of temporal organization in speech. Based on a recent finding about the segmentability of approximants in English an...
