提出了一种以降低识别计算代价为目标的孤立词语音识别系统的设计算法.语音识别系统要求具有很强的实时性,同时应保证较好的识别率.该设计对语音信号采用了处理速度较快的时间轴和幅值上规正化的数据压缩算法,并采用加权离散度法进行识别,算法精确、简便、可靠,适合作为小型语音识别产品的主要算法.

The paper provides a method for designing a set of isolated speech recognition system for the purpose of reducing expense in recognition calculation. Speech recognition has strict real time requirement and high recognition accuracy. More rapid data compress arithmetic is used to process speech signal data by normalizing them in time and amplitude. A more efficient, easier and higher dependability recognition methodthe method of discrete degree added by power is provided in the paper. The arithmetic is suited for designing a small speech recognition production.
