中文摘要: 提出基于深层声学特征的端到端单声道语音分离算法,传统声学特征提取方法需要经过傅里叶变换、离散余弦变换等操作,会造成语音能量损失以及长时间延迟.为了改善这些问题,提出了以语音信号的原始波形作为深度神经网络的输入,通过网络模型来学习语音信号的更深层次的声学特征,实现端到端的语音分离.客观评价实验说明,本文提出的分离算法不仅有效地提升了语音分离的性能,也减少了语音分离算法的时间延迟.
Abstract:An end-to-end single channel speech separation algorithm based on deep acoustic feature is proposed. The traditional acoustic feature extraction methods require the Fourier transform, discrete cosine transform and other operations. This will cause speech energy loss and long latency. In order to improve these problems, the original waveform of the speech signal is used as an input to a deep neural network, deeper acoustic features of the speech signal are learned through a network model. Objective evaluation shows that the proposed algorithm not only improves the performance of speech separation effectively, but also reduces the time delay of speech separation algorithm.
