Speech Feature Denoising and Dereverberation via Deep Autoencoders for Noisy Reverberant Speech Recognition
robust speech recognition feature denoising denoising autoencoder deep neural network
2014/11/27
Denoising autoencoders (DAs) have shown success in generating robust features for images, but there has been limited work in applying DAs for speech. In this paper we present a deep denoising autoenco...

Multi-level Context-dependent Acoustic Modeling Automatic Speech Recognition
2014/11/27
In this paper, we propose a multi-level, contextdependent acoustic modeling framework for automatic speech recognition. For each context-dependent unit considered by the recognizer, we construct a set...
An Efferent-Inspired Auditory Model Front-End for Speech Recognition
efferent auditory model feature extraction
2014/11/27
In this paper, we investigate a closed-loop auditory model and explore its potential as a feature representation for speech recognition. The closed-loop representation consists of an auditory-based, e...

车载语音识别系统设计与试验（Design and Experiment of a Vehicular Speech Recognition System）
车辆 语音识别系统 动态时间归整算法
2010/1/28
用改进的动态时间归整（DTW）算法进行语音辨识，设计了语音识别系统软件，以SPCE061A单片机为核心设计了车载语音识别系统的电控单元（ECU）。在车内不同噪声环境下进行了语音识别试验，结果表明语音识别率随着车内环境噪声的增加而下降，随着语音字数的增加而降低；在车辆怠速车内噪声小于50dB(A)的环境中2字语音平均识别率为90%、4字语音的识别率为85%； 在车辆定置油门半开、车内噪声为60～70...
