| 摘 要： | 为提高语音识别系统在噪音情况下的识别率,提出了一种融合信号级去噪、参数级去噪、模型级去噪的方法.首先用谱减法对带噪的语音信号进行去噪,再利用Mel倒谱系数(MFCC)对处理后的语音信号进行特征提取,最后经过并行模型结合处理法(PMC)处理得到较高识别率的语音信号.

| Abstract: | In order to improve the recognition rate of the speech sound system under noisy circumstances, one special method is put forward in this paper, whichintegrates the methods of the signal denoising, parameter denoising and model denoising. This method first employs spectral subtraction to denoise the system and then extracts the features with the aid of MFCC. Finally, after PMCC -processing, the speech sound signal of a higher recognition rate is attained. |
