基于麦克风阵列的声源定向时延估计的研究

近年来随着传感器技术不断发展和语音信号定向处理技术的不断研究,应用在这种领域的技术以及应用也在逐渐进入人们的视野,比如语音定位、语音跟踪系统等,更是被广泛的应用于军用和民用领域,比如会议说话人的定位以及在战地勘探方面等,这都为语音信号处理等领域的技术发展提供了极大的推动。所以,研究探索技术的工程实践应用这方面的技术,对推动语音信号等处理理论发展和相关技术的成果,有着非常重大的意义。文章着重介绍了语音定向的相关算法与研究,主要探究了延时估计。延时估计是利用麦克风阵列解决宽带语音的信号的技术之关键,更是通过麦克风阵列进行声音源定向方法中最常用的一种。

In recent years, with the continuous development of sensor technology and the continuous research of directional pro- cessing technology of speech signal, the technology and application applied in this field are gradually entering people/s field of vision, such as speech localization, speech tracking system and so on. It is widely used in militaPy and civilian fields, such as conference speaker positioning and field exploration, which provide a great impetus to the development of speech signal processing and other fields. Therefore, it is of great significance to study and explore the technology- of engineering practice and application of this technol- ogy to promote the development of speech signal processing theory and related technology-. This paper focuses on the related algo rithms and research of speech orientation, and mainly explores the delay estimation. Delay estimation is the key technology to solve the broadband speech signal using microphone array, and it is also one of the most commonly used methods of sound source orientation through microphone array.
