A parametric approach to intonation acquisition research: Validation on child-directed speech data

摘要

This paper validates a parametric approach to intonation acquisition research [1] using child-directed speech data. An advantage of this approach is that it can be used for studying child speech as well as adult speech. Within the field of prosody acquisition it reconciles independent approaches to child prosody with ToBI-based approaches. In this paper we substantiate this claim by showing that clusters of parameterized contours obtained from German child-directed speech correlate with GToBI(S) categories, and by elaborating how, alternatively, the parameters can be mapped to properties that are relevant in independent approaches.
