| 摘 要： | 本文在丢失数据技术与声学后退技术的基础上,提出了一种基于模糊规则的鲁棒语音识别方法,首先根据先验知识或假定建立特征分量的可靠程度与其概率分布之间的模糊规则,识别时观察矢量的输出概率由一个基于规则的模糊逻辑系统来得到,并针对倒谱识别系统给出了一种具体的实现方法.实验结果表明,所提识别方法的性能显著优于丢失数据技术和声学后退技术.

| Abstract: | This paper proposes a new fuzzy-rule-based approach for noisy speech recognition based on the missing data and acoustic backing-off techniques. First for each feature component the fuzzy rules between its reliability level and distribution are built using prior knowledge or assumptions. Then in the recognition process the output probability of an observation is calculated by a rule based fuzzy logic system. The proposed approach is implemented on a cepstral speech recognizer. Experimental results show that it significantly outperforms the missing data and acoustic backing-off techniques. |
