Abstract: This paper does much labeling according to the law of the Uyghur’s accent location, and extracts different characteristic parameters（energy, pitch and so on）, does single flow, triage and feature fusion recognition to each characteristic parameters and compares analysis of the characteristic parameters to accent detection and identification rate. The feature after the integration of high dimensional flow characteristics using PCA is done dimensionality reduction and the redundant processing, and the recognition experiments are done. In the light of the recognition accuracy rate, combined with speech linguistic knowledge the experimental results are analysed.

Key words: Uyghur, accent detection, feature fusion, Principal Component Analysis（PCA）
