Speech production model and its application to speech synthesis system -speech synthesis by mimicing human speech production-

摘要

Speech is produced by articulating speech organs such as the jaw, tongue, and lips. We have developed an articulatory-based speech synthesis model that converts a phoneme string into a con- tinuous acoustic signal by mimicing the human speech production process. This paper describes a computational model of the speech production process which involves a motor process to generate articulatory movements from the motor task sequence and articulatory-to-acoustic mapping to de- termine the vocal-tract acoustic characteristics.
