| 抄録 | （和） | This paper presents a method of prosody reconstruction that can be used to synthesize conversational speech. In our method, we use a conventional text-to-speech engine to initially generate reading-style prosody for input text. We then use a frequency modulation technique to rescale the fundamental frequency (F0) contours to add the communicative functions of intonation to the synthesized speech. The frequency modulation technique is based on a functional F0 model, and the transformation scales are modeled by combining simple piecewise-linear patterns according to input tags. We conducted two experiments to evaluate our method: modulating the F0 range of reading-style prosody when synthesizing Japanese speech to convey "good news" and "bad news" (Experiment 1), and making a narrow focus when synthesizing Chinese dialog to convey emphasis (Experiment 2). The results of Experiment 1 showed that the listeners judged 94% of samples modulated with "bad news" F0 ranges as "bad news" and 78% of samples with "good news" F0 ranges as "good news." They are comparable with those obtained by style-specified corpora in our previous work. In Experiment 2, 90% of the samples with narrow focuses were identified. The results showed that proposed method could use paralinguistic information to achieve specific communicative purposes. |
