摘要
论述了强背景噪声环境下利用模糊分类算法对大词汇量的汉语语音进行分类识别,根据噪声中的汉语语音特点,采用有边界的交叉分类和无边界的模糊分类相结合的措施,较成功地解决了强噪声环境下的汉语语音分类.该算法在75dB的强噪声环境下,对500个汉语短语进行识别,其识别精度达到95%,取得了较好的识别效果.
A method utilizing fuzzy classified algorithms for the speech recognition of the Chinese language with a large vocabulary in a strong noise environment was proposed. Accoding to the phonetic characteristics of the Chinese language, the boundary crossing classified and the boundaryless fuzzy classified algorithems were successfully used in classifying the Chinese language with a large vocabulary in a strong niose environment. Good results were achieved in applying these algorithms to speech recognition system.The correctly recognizing rate is 95% of 500 Chinese phrases under test in the 75dB noise enviroment.
