| 摘 要： | 提出一种用于语音识别的性别鉴定的算法,算法融合基音频率鉴定法和隐马尔可夫模型(HMM)鉴定法的混合算法.循环幅度差函数用于检测基音频率,HMM鉴定法建立男女两个HMM,用Viterbi算法将输入语音匹配到这两个模型,用匹配结果鉴定性别,基于这两种方法设计了一个线性分类器,在TIMIT、HTIMIT和南方口音语料库上采用1s长的语音片段进行测试,达到98.54%的正确率.将该算法应用于连续语音识别前端,较大提高了识别精度.

| Abstract: | Proposes an hybrid algorithm for gender identification based on Hidden Markov Model (HMM) and pitch detection. The performances of the algorithm is evaluated on TIMIT, HTIMIT and CASIA corpora. Both algorithm performances well and the accuracy of ASR tested on TIMIT and CASIA corpora is improved after adding the gender identification into the ASR system. |
