摘要
文章给出了基于DSP的特定人口令式语音CDHMM(连续隐马尔可夫模型)的实时训练系统。在分析了CDHMM训练算法运算特性的基础上,采用TI高性能浮点DSP芯片TMS320C6711成功实现了口令式语音的CDHMM的训练。并对系统的存储量及实时性做了深入研究,为语音识别在嵌入式领域中的应用提供了重要的技术途径。
In this paper, one CDHMM real-time training system of token-based speech based-on DSP is proposed. Through analyzing CDHMM training algorithm, this system is implemented successfully in using high performance float-point DSP TMS320C6711 of TI incorporated. At the same time, the system's storage need and real-time performance are discussed. Thus an important approach of applying speech recognition system in embedded devices is proposed.
