A survey of speech enhancement algorithms

Wei Zhang, Zhongzheng Wang, Xin Shi, Xiaojing Lao, Huihui Zhang


speech is easy to be interfered by the external environment in real applications, resulting in the reduction of speech
intelligibility and signal-to-noise ratio. In the past few decades, due to the wide application of speech based solutions in practical
applications, speech enhancement of noisy speech signals has aroused considerable research interest. This paper classifi es and introduces
several main speech enhancement methods, summarizes the advantages and disadvantages of several main methods, and fi nally puts forward
the next research direction of speech enhancement methods.
