Prosodic and linguistic features of spontaneous Japanese conversational speech are analyzed. Prosodic features, of prominence in particular, are first analyzed for a corpus consisting of 50 sentences in discussion on coeducation spoken by a male announcer as well as male and female high-school students. The analysis results show that speech-rate reduction in parts where prominence is placed is a conspicuous feature in spontaneous conversational speech spoken by the male high-school students. The mean mora duration for marked words is 130ms, whereas the mean mora duration for neutral words is 89ms. As for linguistic features, several habits of saying inherent in spontaneous speech are observed common to a plural number of speakers, and a speaker tends to speak to a specific person even in discussion among more than two people.
