一个基于LB/IHMM的高性能汉语连接数字语音识别系统

A High Performance Connected Digit Speech Recognition System Based

本文使用一种ＩＨＭＭ的简化训练算法，讨论了一个基于ＬｅｖｅｌＢｕｉｌｄｉｎｇ搜索算法，参考模式基于ＩＨＭＭ模型的高性能的汉语连接数字语音识别系统。文中详细描述了系统的特征提取、ＩＨＭＭ模型、训练过程和识别过程，以及系统用于特定人、多说话人和不认人语音识别的实验，并且对实验结果进行了分析和讨论。

By using an IHMM easy estimation training algorithm this paper discusses Chinese connected digit speech recognition system with efficient performance, and based on Level Building searching algorithm,whose reference patterns use IHMM mode. The paper describes the theory of the system. It includes its feature extracting, IHMM mode, training procession,recognition procession, and the experiments that are used for speaker trained, multi speaker and speaker independent mode. The results of the experiment are analyzed and discussed.
