摘要： A speech synthesis unit, in which a natural speech is cut and taken out separately in predetermined time intervals, the acoustic characteristics and parameters in the predetermined time interval are abstracted and then speech is synthesized based on these characteristics and parameters. The speech synthesis unit alone can process different quantities of the acoustic parameter information. For this purpose, the time interval of one analysis frame is changed so as to change the information quantity per unit of time, without any variation of the number of bits of the characteristics and parameters distributed in one analysis frame, and the time interval of one synthesis frame in the synthesizing unit is correspondingly changed so as to match the time interval of one analysis frame with the time interval of one synthesis frame.

摘要翻译： 一个语音合成单元，其中自然语音在预定的时间间隔内被分开和分开取出，抽取预定时间间隔内的声学特性和参数，然后根据这些特性和参数合成语音。 语音合成单元可以单独处理不同数量的声学参数信息。 为此，改变一个分析帧的时间间隔以改变每单位时间的信息量，而不改变分布在一个分析帧中的特性和参数的位数，并且一个分析帧的时间间隔 相应地改变合成单元中的合成帧，以使一个分析帧的时间间隔与一个合成帧的时间间隔相匹配。
