摘要
介绍了语音识别的一般概念,利用MFCC对语音信号的特征信息进行了提取,在分析VQ模型和人工神经元网络的基础上,提出了一种VQ模型与神经元网络相结合的方法,并且建立了相关的数学模型.通过MATLAB仿真证明该模型具有很好的稳定性.
The conception of voice recognition is presented in this article. Based on the method of MFCC,the characteristics extraction of voice signal is introduced. Based on studying traditional VQ model and Neural network model, a way of using VQ combined with neural network is proposed, what is more a mathematical model is established. The experiment based on matlab show the the system possesses a stable quality.
