%X In order to impersonally assess the quality of the following speech in the language speaking training, and carry out it in embedded system, a method of speech assessment based on feature comparison was proposed. The input speech was analysed, and the feature was extracted to match with the reference speech. The result was given by the mechanism based on the similarity of the speech. Experiment shows that the algorithm complexity is low, and the result of the assessment is approximately consistent with the subjective feeling.
