Abstract

In this study, an acoustic analysis of the dental fricatives as produced by American English speakers from the Buckeye Corpus (Pitt et al. 2006) reveals that the dental fricatives are subject to variation in voicing based on phonetic environment, much more than is usual for a pair of phonemes whose phonological distinction is based on voicing, confirmed by a comparison with the voicing of /f/ and /v/. The results of the study show that voicing (presence or absence of glottal pulses) for /θ/ and /ð/ is not predictable by phoneme in conversational speech, but it is more predictable based on voicing of surrounding sounds.
