Outline of Final Research Achievements |
We carried out a series of studies to develop a system to measure and improve the perceived likability of speech. The experiments showed that there was an appropriate range in speed of speech and duration of pauses. In pitch and timbre, we found the speech parameters related to the perceived likability. In this study, we utilize a vocoder technology to control the pitch of speech. In the timbre, we proposed a signal processing method to control the spectral centroid, which roughly corresponds to the brightness of the speech. A subjective evaluation using the proposed method was carried out. The result suggested that it was possible to improve the likability of the input speech. We implemented a prototype of a speech-likability measurement system that incorporates these technologies and confirmed that it works in a real-world environment.
