The Analysis of Influence Factors and Identification of Speaker-Dependent Primi Speech Recognition

* Corresponding author Abstract—The research object is an endangered minority language of Primi on the southern dialect. This paper takes isolated-word of Primi as the primitive and uses large vocabulary of speech corpora based on HTK. The effect of different quantity of vocabularies, the sample ratio of training and testing, and the data quality on recognition rate of speaker-dependent were investigated. In addition, the identification of speaker-dependent acoustic model were compared. The experimental results show that the high quality data can improve the recognition rate and has little effect on the recognition rate in the vocabulary size.
