Synthesis of Chinese by rules based on a multipulse excitation model Free

According to the model of speech production, the characteristic parameter of speech can be divided into two parts: excitation and vocal tract parameters. Atal proposed the multipulse excitation model that can produce high‐quality sythesized speech. This research shows that the intensity, duration, and pitch mode of single syllable Chinese produced by multipulse excitation may be changed when the adaptive method is utilized to process its multipulse sequences and vocal tract parameter. There are about 10 000 Chinese words in common use, but the pronunciation of many words is the same, so that only about 1300 syllables are independent. The Chinese language is a tone language. Each Chinese word is of four pitch modes, and the vocal tract parameter for the four modes of one word is almost the same. Therefore, there are 400 independent vocal tract parameters and 1300 multipulse sequences in Chinese. Based on the above strategy, a new method of sythesizing Chinese by rules has been proposed. The intelligibility and naturalness of the synthesized speech are satisfactory.
