Visual Habituation

Purpose This study assessed the role of spectro-temporal modulation cues in the discrimination of 2 phonetic contrasts (voicing and place) for young infants. Method A visual-habituation procedure was used to assess the ability of French-learning 6-month-old infants with normal hearing to discriminate voiced versus unvoiced (/aba/-/apa/) and labial versus dental (/aba/-/ada/) stop consonants. The stimuli were processed by tone-excited vocoders to degrade frequency-modulation cues while preserving: (a) amplitude-modulation (AM) cues within 32 analysis frequency bands, (b) slow AM cues only (<16 Hz) within 32 bands, and (c) AM cues within 8 bands. Results Infants exhibited discrimination responses for both phonetic contrasts in each processing condition. However, when fast AM cues were degraded, infants required a longer exposure to vocoded stimuli to reach the habituation criterion. Conclusions Altogether, these results indicate that the processing of modulation cues conveying phonetic information on voicing and place is “functional” at 6 months. The data also suggest that the perceptual weight of fast AM speech cues may change during development.

Closure Duration

In the Southern Bavarian variety of Tyrolean, laryngeal contrasts undergo a typologically interesting process of neutralisation in word-initial position. We undertake an acoustic analysis of Tyrolean stops in word-initial, word-medial intersonorant and word-final contexts, as well as in obstruent clusters, investigating the role of the acoustic parameters VOT, prevoicing, closure duration and F0 and H1–H2* on following vowels in implementing contrast, if any. Results show that stops contrast word-medially via [voice] (supported by the acoustic cues of closure duration and F0), and are neutralised completely in word-final position and in obstruent clusters. Word-initially, neutralisation is subject to inter- and intraspeaker variability, and is sensitive to place of articulation. Aspiration plays no role in implementing laryngeal contrasts in Tyrolean.

Perceptual Evidence

ABSTRACTPronunciation variation is under-studied in infant-directed speech, particularly for consonants. Regressive place assimilation involves a word-final alveolar stop taking the place of articulation of a following word-initial consonant. We investigated pronunciation variation in word-final alveolar stop consonants in storybooks read by forty-eight mothers in adult-directed or infant-directed style to infants aged approximately 0;3, 0;9, 1;1, or 1;8. We focused on phonological environments where regressive place assimilation could occur, i.e., when the stop preceded a word-initial labial or velar consonant. Spectrogram, waveform, and perceptual evidence was used to classify tokens into four pronunciation categories: canonical, assimilated, glottalized, or deleted. Results showed a reliable tendency for canonical variants to occur in infant-directed speech more often than in adult-directed speech. However, the otherwise very similar distributions of variants across addressee and age group suggested that infants largely experience statistical distributions of non-canonical consonantal pronunciation variants that mirror those experienced by adults.
