摘要： 该测试工具的主要目的是实现电话业务语音的自动识别功能，对从电话交换机采集到的业务语音输出进行分析，检验交换机的输出是否正确。识别对象主要为无失真传输语音。采用基于特征空间语音轨迹的声学特征模式匹配法组织识别内核，为了实现识别的高速性和高效性，特别讨论了识别对短时能量特征的充分利用以及判决的策略，并在最后对测试数据进行了分析。

Abstract: This test tool is designed to recognize the operation speech automatically, it analyses the operation speech out come from the switcher, and verifies if the output of switcher is correct. The object to be recognized is mainly the non-distortion transfer speech. The recognition core of this tool is feature space trace acoustic feature pattern matching method. In order to make recognition in high speed and more efficiently, this article comes to make the best of short time energy feature and the judgment. At last, the test data is analyzed.
