The naturalness of synthetic speech depends strongly on the prediction of appropriate prosody. For the present study the original annotation of the German speech database “Kiel Corpus of Read Speech” was extended automatically with syntactic features, word frequency, and syllable boundaries. Several classification and regression trees for predicting symbolic prosody features, postlexical phonological processes, duration, and F0 were trained on this database. The perceptual evaluation showed that the overall perceptual quality of the German text-to-speech system MARY can be significantly improved by training all models that contribute to prosody prediction on the same database. Furthermore, it showed that the error introduced by symbolic prosody prediction perceptually equals the error produced by a direct method that does not exploit any symbolic prosody features.
This paper presents the concept of the "participant perspective" as an approach to the study of spoken language. It discusses three aspects of this concept and shows that they can offer helpful tools in spoken language research. Employing the participant perspective provides us with an alternative to many of the approaches currently in use in the study of spoken language in that it favours small-scale, qualitative research that aims to uncover categories relevant for the participants. Its results can usefully complement large-scale studies of phenomena on all linguistic dimensions of talk.
In her overview, Margret Selting makes the case for the claim that dealing with authentic conversation necessarily lies at the heart of an interactionallinguistic approach to prosody (see Selting this volume, Section 3.3). However, collecting and transcribing corpora of authentic interaction is a time-consuming enterprise. This fact often severely restricts what the individual researcher is able to do in terms of analysis within the scope of his or her resources. Still, for dealing with many of the desiderata Margret Selting points out in Section 5 of her extensive overview, the use of larger corpora seems to be required. In this commenting paper, I want to argue that future progress in research on prosody in interaction will essentially rest on the availability and use of large public corpora. After reviewing arguments for and against the use of public corpora, I will discuss some upshots regarding corpus design and issues of transcription of public corpora.
