摘要
语音识别可实现人机交互和语音控制,在工业控制、消费电子等领域都有广泛应用。结合人发音的生理结构的特点,使用LPMCC(LPC倒谱美尔变换)作为特征向量,采用动态规划算法作为核心识别算法,在TMS320VC5402芯片上实现了特定人、孤立词的高性能实时识别系统。
Speech recognition can achieve human-computer interaction and voice control, and it is used in industrial control, consumer electronics and many other fields. Combined with the mechanism of the production of human＇s voice, a high perform speech recognition system is built for specific people on TMSVC5402 DSP by using the LPMCC as the feature vector and using dynamic time warping as the matching algorithm.
