| 摘 要： | 针对广播节目在传输过程中易受干扰的问题,提出了基于动态时间轴归整（DTW）算法的多词判别法语音识别技术,根据该方法通过提取Mel尺度倒谱参数,设计出基于DSP的广播节目抗干扰系统,实现广播信号的自动判别,实验表明该系统抗干扰能力显著增强.

| Abstract: | Aiming at the problem that broadcasting programs are highly likely to be interfered in the process of delivery,it put forward speech recognition technique of distinguishing method by multiword based on Dynamic Time Warping（DTW） arithmetic.Withdrawing Mel-Frequency Cepstrum Coefficients,the corresponding anti-interference systems,on the basis of DSP,has been designed by this method,and the system can automatically distinguish program signals.The experiment indicates the dramatic increase of the anti-interference＇s ability. |
