摘　　要：根据时域基音同步叠加算法设计了一个用于普通话的语音调节系统。首先,本文对文语转换技术和时域基音同步叠加算法进行了简要的介绍,并推导了算法的计算过程。接下来,本文为文语转换系统设计了两种接口函数。然后,本文对常用中文音节进行了测试,并给出了一个中文音节的测试结果。测试结果表明,本系统能够对语音的基频、时长等参数进行灵活调节。This paper designs a system to modify mandarin speech using TD-PSOLA algorithm. First, a brief introduction on TTS and TD-PSOLA is made. Subsequently, two API functions for TTS system are designed. And then, common syllables in mandarin are tested, and result of a syllable is showed as an example. Finally, it has been proved that pitch and duration of speech can be modified flexibly.

关 键 词：普通话 时域基音同步叠加算法 语音参数调节
