论文给出一种基于嵌入式系统的语音口令识别系统的设计方案,该系统的硬件电路由嵌入式微处理器和音频处理等主要芯片组成,采用Windows CE操作系统,语音口令识别算法为连续隐马尔可夫模型。实验结果表明,随着嵌入式微处理器性能的不断提高和价格的不断下降,对运算量要求比较高的语音口令识别技术就可以通过嵌入式系统来实现,并且应用到许多需要使用口令控制的便携式设备中。
This paper presents a design scheme of speech password recognition system based on embedded system. The hardware circuit of the system is composed of main chips such as embedded microprocessors and audio processing. Using Windows CE operating system and voice password recognition algorithm as continuous Hidden Mark Kovar model. Experimental results show that with the continuous improvement of embedded microprocessor performance and the ever-decreasing price, voice password identification technology with high computational requirements can be implemented in embedded systems and applied to many portable devices that require password control Equipment.
