| Abstract(in English) | A speech synthesis system that simulates speech production process; generation of sound source, articulation and radiation has a potential for producing human-like synthesized speech. Taking advantage of the continuity of the vocal tract shape for synthesizing natural continuous speech, we have developed a speech synthesis system using a transmission line model. In the system, a vocal tract is modeled as 20 acoustic tubes and change in the areas of the acoustic tubes as a function of time is described using the time pattern of the step response of a cascaded first order system. Controlling temporal structure between articulatory movement and vocal fold vibration is important for producing stop consonants such as /p/, /t/ and /k/. In this paper, a GUI-based simulation system has been developed in order to investigate relative timing between articulation and vocal fold vibration. The simulation results showed adequate ranges between both the events for producing successful consonant sounds /p/, /t/ and /k/. These results allowed us to improve the speech synthesis system so that related parameters can be automatically adjusted for specified phoneme duration. |
