摘要： 提取测试声乐和相应原声的音强、音高、气息等特征参数，采用特征匹配方法对各参数进行比较，由评分机制根据其相似程度给出客观评分。建立多媒体声乐客观评价系统，提高了声乐教学的直观性和互动性。仿真实验结果表明，该方法的算法复杂度较低，其评分结果与人的主观感觉相符。

Abstract: This paper extracts feature parameters of the test vocality and the corresponding original vocality, such as sound intensity, pitch, and breath. It uses feature matching method to compare these parameters and obtains objective assessment score by using assessment mechanism according to the similarity of these parameters. An objective assessment system of multimedia vocality is established to improve the intuitiveness and interactivity of vocality teaching. Simulation experimental results show that this method has a low algorithm complexity and consistent with human’s subjective feeling.

Key words: _{fundamental frequency track,} dynamic time normalization, feature matching
