本文研究了一种基于非负矩阵分解(NMF)的方法来解决仅给出非平稳加性噪声信号的半监督单通道语音增强问题。所提出的方法依赖于语音生成的正弦模型,该模型使用字典原子的线性约束集成在 NMF 框架内。该方法进一步发展用于规范谐波幅度。提出了简单的乘法算法。实验评估是在混合有各类噪声的TIMIT语料库上进行的。事实证明,所提出的方法在信噪比方面优于一些最先进的噪声抑制技术。
This paper investigates a non-negative matrix factorization (NMF)-based approach to the semi-supervised single-channel speech enhancement problem where only non-stationary additive noise signals are given. The proposed method relies on sinusoidal model of speech production which is integrated inside NMF framework using linear constraints on dictionary atoms. This method is further developed to regularize harmonic amplitudes. Simple multiplicative algorithms are presented. The experimental evaluation was made on TIMIT corpus mixed with various types of noise. It has been shown that the proposed method outperforms some of the state-of-the-art noise suppression techniques in terms of signal-to-noise ratio.
