Toward a Pronunciation Scoring Method Based on Multi-Feature Fusion

Jie Yang
Abstract—Pronunciation scoring tries to evaluate on voice segmentation objectively with related recognition technologies. The voice to be evaluated (VBE) was compared with standard voice (SV) to arrive at a score in accordance with similarity. The system firstly extracted feature parameters from VBE and SV. Two parameters of linear predictive cepstral coefficients (LPCC) and Mel-frequency cepstral coefficients (MFCC) were selected. The distance between SV vector and VBE vector was computed with dynamic time warping (DTW) algorithm. According to scoring formula, the obtained distance was translated into score, which can be regarded as evaluation on VBE. Experiment shows that expert scoring and system scoring have a high correlation by combining LPCC and MFCC.

Index Terms—Pronunciation scoring, feature parameter, dynamic time warping.
