基于61单片机的语音识别系统

摘要：语音识别是实现人机通信的一种重要技术手段。本文设计了一种基于SPCE061A单片机的语音识别系统，重点讨论了其硬件子系统的设计与实现。完成了针对特定人、小词汇量和孤立词的嵌入式语音识别系统开发。首先介绍了语音识别过程的各个环节及其实现方法，进行了识别系统的硬件设计、软件开发和系统调试。最后应用本文设计的系统，针对特定人进行了一系列识别实验(包括孤立字、词和短语)。实验结果表明，该系统具有比较好的识别效果。

Design Of Speech Recognition System Based On 61MCU

Abstract: Speech recognition is to achieve an important man-machine communication technology. In this paper, a SPCE061A-based single-chip speech recognition system, focused on hardware design and implementation of subsystems. Completed for a particular person, a small vocabulary and isolated word speech recognition for embedded systems development. First of all, the process of introduced speech recognition in all aspects of its implementation, a hardware identification system design, software development and system debugging. In this paper, the final design of the system application-specific identification of who carried out a series of experiments (including isolated words, words and phrases). The experimental results show that the system has a better recognition effect.
