| 摘 要： | 为在语言朗读训练时对跟读语音的质量自动作出客观评价并在嵌入式系统上实现，提出了一种基于特征比较的语音评分方法。通过分析输入语音，提取语音特征并与参考标准进行匹配比较，由评分机制根据相似程度大小给出评价得分。实验证明该方法的算法复杂度较低，评分结果符合人的主观感觉。

| Abstract: | 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. |
