Abstract: This paper first narrates the principles of the speech synthesis and the text-to-speech technology. Then a new technology named PSOLsA (Pitch- Synchronous Overlap Add ) which can be used to prosodic modifications is introduced. A PSOLA based waveform coding synthesis technology in the Chinese TTS system is proposed and implemented to approve the speech's naturality and the auditory effect

摘要： 首先简述了语音合成技术和文一语转换的基本原理，然后介绍了一种可用来进行韵律修正的基音同步叠加（ＰＳＯＬＡ）技术。在此基础上，提出用基于ＰＳＯＬＡ的波形编辑语音合成技术应用于汉语ＴＴＳ系统中，以提高输出语音的自然度和听觉效果。
