Effects on word recognition of syllable-onset cues to syllable-coda voicing

Abstract

It is well known that syllables in many languages have longer vowels when their codas are voiced rather than voiceless (for English, cf. Jones 1972; House and Fairbanks 1953; Peterson and Lehiste 1960; for other languages, including exceptions, see Keating 1985). In English, the durational difference in stressed syllables can be 100 ms or more, and it is well established as one of the strongest perceptual cues to whether the coda is voiced or voiceless (e.g. Denes 1955; Chen 1970; Raphael 1972). More recently, van Santen, Coleman and Randolph (1992) showed for one General American speaker that this coda-dependent durational difference is not restricted to syllabic nuclei, but includes sonorant consonants, while Slater and Coleman (1996) showed that, for a British English speaker, the differences tended to be greatest in a confined region of the syllable, the specific location being determined by the syllable's segmental structure.
