摘要
结合PDA的自身特点,讨论了新型嵌入式语音识别系统ESRS;同时重点讲述了ESRS的系统结构框架和实现的关键技术,包括基于时域能量的端点检测、基于隐马尔可夫模型的拒识技术、特征提取和抗噪技术。
In view of PDA's characteristics,describes the up to date ESRS for data retrieving. Specially,emphasizes structure frame and crucial technologies of ESRS,including timedomainenergybased endpoint detection, rejection technology based on hidden Markov model,feature extraction and antinoise technology.
