Abstract

In this paper we propose a simple algorithm to enhance a speech signal with larger energy from a mixture of two sound sources. We used two microphones for acquisition of the sound signals and assume that either one of the speakers is closer of one of the microphones. In this algorithm, we use the concept of auditory filter banks with two psychoacoustic concepts: lateral inhibition and binaural masking. Preliminary computer simulations experiments confirm the validity of the proposed algorithm by objective and subjective measures

侧抑制和双耳掩蔽的语音增强

在本文中，我们提出了一种简单的算法来增强来自两个声源混合的具有较大能量的语音信号。我们使用两个麦克风来获取声音信号，并假设其中一个扬声器离其中一个麦克风更近。在该算法中，我们将听觉滤波器组的概念与两个心理声学概念相结合:侧抑制和双耳掩蔽。初步的计算机仿真实验从客观和主观两方面验证了该算法的有效性

期刊介绍： Journal of Signal Processing is an academic journal supervised by China Association for Science and Technology and sponsored by China Institute of Electronics. The journal is an academic journal that reflects the latest research results and technological progress in the field of signal processing and related disciplines. It covers academic papers and review articles on new theories, new ideas, and new technologies in the field of signal processing. The journal aims to provide a platform for academic exchanges for scientific researchers and engineering and technical personnel engaged in basic research and applied research in signal processing, thereby promoting the development of information science and technology. At present, the journal has been included in the three major domestic core journal databases "China Science Citation Database (CSCD), China Science and Technology Core Journals (CSTPCD), Chinese Core Journals Overview" and Coaj. It is also included in many foreign databases such as Scopus, CSA, EBSCO host, INSPEC, JST, etc.
