Abstract:

Using computer to identify the speech sounds of minority nationality is an important means to protect and inherit the national culture. The Bai is one of the important minority nationalities in the southwest border of the motherland. It has a long history and the splendid culture. In order to implement human-computer interaction in Bai' s language, a sound recognition method for Bai’s language based on HTK is proposed. According to characteristics of Bai's language, this method structures the HMM model through using phonemes as the basic units and using the HTK tool to extract the speech feature parameters of 39-dimensional MFCC. Viterbi algorithm is used to train the model and match to achieve speech recognition of Bai's language. The experimental result shows that the recognition system can obtain a high recognition rate（up to 93.3%）and also provides a useful reference for the speech recognition research
on minorities' languages.
