First International Conference on Spoken Language Processing (ICSLP 90)
The object of study is the prosody of spontaneous dialogue. The focus is on the methodology that we are developing, and the exemplification is from Swedish. We have been conducting three types of analysis: analysis of dialogue structure, auditory (prosodic) analysis, and acoustic-phonetic analysis. Dialogue structure analysis concerns textual, interactive and turn taking aspects. The auditory analysis takes the form of a transcription encoding five prosodic features: prominence, phrasing, pitch range, boundary tones and pausing. The acoustic-phonetic analysis is centered around pitch, particularly the use of overall pitch range for the expression of textual coherence and boundary of a dialogue. For the modelling of dialogue prosody we have been using rule synthesis. Our preliminary testing shows that variation in pitch range is a potentially important means for signalling textual aspects of a dialogue.
