Now you hear it, now you don't
In this work, we examine a context in which a conflict arises between two roles that infant-directed speech (IDS) plays: making language structure salient and modeling the adult form of a language. Vowel devoicing in fluent adult Japanese creates violations of the canonical Japanese consonant–vowel word structure pattern by systematically devoicing particular vowels, yielding surface consonant clusters. We measured vowel devoicing rates in a corp…
Infant Discrimination of a Morphologically Relevant Word‐Final Contrast
Six‐, 12‐, and 18‐month‐old English‐hearing infants were tested on their ability to discriminate nonword forms ending in the final stop consonants /k/ and /t/ from their counterparts with final /s/ added, resulting in final clusters /ks/ and /ts/, in a habituation–dishabituation, looking time paradigm. Infants at all 3 ages demonstrated an ability to discriminate this type of contrast, a contrast that constitutes one phonetic cue for the English …
Japanese Listeners' Perceptions of Phonotactic Violations
The canonical form for Japanese words is (Consonant)Vowel(Consonant) Vowel~. However, a regular process of high vowel devoicing between voiceless consonants and word-finally after voiceless consonants results in consonant clusters and word-final consonants, apparent violations of that phonotactic pattern. We investigated Japanese adults' perceptions of these violations, asking them to rate both canonical and noncanonical nonsense forms on a scale…
Speech overlap in Japanese mother–child conversations
This study aimed to clarify the development of conversational style in Japanese mother–child interactions. We focused on the frequency of speech overlap as an index of Japanese conversational style, with particular attention to ne , a particle produced by the speaker, and to backchannels, such as ‘uh-huh’, produced by the listener that support sympathetic conversation. The results of longitudinal observations of two Japanese mother–child dyads fr…
