It is of great significance that objective evaluation of speech quality in language self-learning. Aimed at the objective evaluation process of speech quality the thesis presented to build HMM model based speech feature MFCC of human auditory model, and to use different indicators to achieve the evaluation of phoneme, word and sentence. Effective solution was proposed for such issues as the initial model to select more sequence of observations to train HMM as well as data underflow encountered during practical application of HMM algorithm. According to some speech experts, the evaluation results achieved by speech quality evaluation system were objective.
