摘要
在MATLAB环境下利用语音工具箱VoiceBox实现基于连续概率密度隐含马尔科夫模型的汉语语音识别系统。在实时录音的情况下,利用该语音识别系统,不同的人对20条2～8个字的语音命令进行识别,准确率可达到95%,识别时间1 5～3s,实现了小词汇量连续语音的非特定人的实时识别。
Using Voice-Box a mandarin speech recognition system is realized based on CDHMM in MATLAB environment. Under the circumstance of the real-time recording,different people to say the connected words which include 2～8 words in 20 speech utterances,the accuracy can reach 95%,and the recognition time is between 1.5～3 seconds in this system.
