The prosodic marking of accents and phrase boundaries : expectations

چکیده
Using sentence templates and a stochastic context-free grammar a large corpus has been created, where prosodic phrase boundaries are labeled in the sentences automatically during sentence generation. 10,000 sentences of this corpus were recorded and used for our experiments. With perception experiments on 500 utterances we veriied that 92% of the automatically marked boundaries were perceived as prosodically marked. In initial automatic classiication experiments for three levels of boundaries recognition rates up to 81% could be achieved. We also investigated which lexical accents are actually perceived in the utterances.

Signal-based accent and phrase marking using the fujisaki model
Automatic prosodic marking is very important in speech signal processing, since its results are required in many subsections, e.g. speech synthesis and speech recognition. The most important prosodic features on the linguistic level are the marking of accents and phrases. In this paper, we develop an automatic algorithm for marking accents and phrases which analyzes the F0 contour by using the ...
متن کاملEffects of intonational phrase boundaries on pitch-accented syllables in american English
Recent studies of the acoustic correlates of various prosodic elements in American English, such as prominence (in the form of phrase-level pitch accents and word-level lexical stress) and boundaries (in the form of boundary-marking tones), have begun to clarify the nature of the acoustic cues to different types and levels of these prosodic markers. This study focuses on the importance of contr...
متن کاملDoctoral Thesis Proposal Automatic Detection and Classification of Prosodic Events
Speech prosody is a valuable carrier of information. Accents and phrase boundaries have been shown to contribute to syntactic disambiguation, semantic, pragmatic and paralinguistic interpretation, and to convey information about topicality, focus, contrast and information status. This thesis will present and evaluate techniques to detect and classify these prosodic events. The acoustic correlat...

متن کاملAutomatic accentuation and prosodic phrasing for dutch text-to-speech conversion
Correct accentuation and phrasing improves the quality of synthetic speech. This paper discusses an algorithm which assigns both sentence accents and phrase boundaries on the basis of the prosodic sentence structure. Although this latter structure is theoretically derived from the syntactic structure, the present algorithm deterrnines the prosodic structure by means of (linguistically and stati...
