Previous research has argued that fundamental frequency is a critical component of phonetic accommodation. We tested this hypothesis in an auditory naming task with two conditions. Participants in an Unfiltered Condition completed an auditory naming task with a single male model talker. A second group of participants was assigned to a Filtered…

American listeners' perception of Japanese contrasts of vowel length (e.g., kiro vs. kiiro), consonant length (e.g., kite vs. kitte) and syllable number/length (e.g., kjoo vs. kijoo) was examined. Stimuli consisted of sentence-length utterances produced by a native Japanese talker; five minimal pairs of each contrast type were included. Questions…

Certain ill-formed phonological structures are systematically under-represented across languages and misidentified by human listeners. It is currently unclear whether this results from grammatical phonological knowledge that actively recodes ill-formed structures, or from difficulty with their phonetic encoding. To examine this question, we gauge…

It is well established that speakers accommodate in speech production. Recent work has shown a similar effect in perception--speech perception is affected by a listener's beliefs about the speaker. In this paper, we explore the consequences of such perceptual accommodation for experiments in speech perception and lexical access. Our interest is…

This study investigated identification of fragmented Mandarin tones by non-native listeners. Monosyllabic Mandarin words were digitally processed to generate intact, silent-center, center-only, and onset-only syllables. The syllables were recorded with two carrier phrases such that the offset of the carrier tone and the onset of the target tone…

This study examined the perception of the four Mandarin lexical tones by Mandarin-naive Hong Kong Cantonese, Japanese, and Canadian English listener groups. Their performance on an identification task, following a brief familiarization task, was analyzed in terms of tonal sensitivities (A-prime scores on correct identifications) and tonal errors…

Listeners can explicitly categorize unfamiliar talkers by regional dialect with above-chance performance under ideal listening conditions. However, the extent to which this important source of variation affects speech processing is largely unknown. In a series of four experiments, we examined the effects of dialect variation on speech…

Previous research has shown that English infants are sensitive to mispronunciations of vowels in familiar words by as early as 15-months of age. These results suggest that not only are infants sensitive to large mispronunciations of the vowels in words, but also sensitive to smaller mispronunciations, involving changes to only one dimension of the…
