摘要: 根据汉语普通话中数字串发音的韵律规则和特点,利用LMA语音合成器,实现了一种全新的数字串报号系统。本系统可以在不足300kbytes的极小的音库容量下,通过采用预先计算、查表拼接快速处理方法,在各种特定应用场合下多路实时实现高自然度、高音质的任意多位的数字号码的合成语音。测听实验和用户反馈信息均表明,合成输出语音的听觉效果已经可以与播音员原始发音相媲美。

Abstract: Based on the prosodic characteristics of Chinese digit strings and the application of the LMA synthesizer, a new speech synthesis system is introduced in this paper. Using pre-calculating and table-searching methods, the system can produce synthesized speech for digit strings with various lengths in a multi-channel and real time way. Besides the high speed, little speech library (less than 300 Kbytes), high naturalness and clarity are the three other outstanding features of this system. Listening tests andusers' evaluation showed that the perceptual effect of the output from the new system was much close to the original speech.
