特定人语音控制音乐播放器软件系统设计

摘要

语音识别技术是人类迈向高度智能化和自动化的信息社会所必备的关键技术之一。经过几十年的艰苦探索和研究，语音识别技术获得了极大的发展，一些比较成熟的技术已经逐步应用于日常生活中。

语音识别是解决机器“听懂”人类语言的一项技术。作为智能计算机研究的主导方向和人机语音通信的关键技术，语音识别技术一直受到各国科学界的广泛关注。如今，随着语音识别技术研究的突破，其对计算机发展和社会生活的重要性日益凸现出来。以语音识别技术开发出的产品应用领域非常广泛，如声控电话交换、信息网络查询、家庭服务、宾馆服务、医疗服务、银行服务、工业控制、语音通信系统等，几乎深入到社会的每个行业和每个方面。

本文阐述了基于MATLAB软件上实现的特定人语音控制播放器软件系统的设计，实现应用MATLAB软件编程达到控制播放器的功能，语音控制模式能够识别特定人“开”、“关”、“暂停”等语音指令并实现相应控制，以代替传统的鼠标或按键操作控制播放器的开关机和播放。

Abstract

Speech recognition is one of the most indispensable technologies for human to realize a highly intellectual and fully roboticized information society in the future. With many researchers' enormous efforts, the past tens of years have witnessed significant progress in speech recognition technologies and parts of them have already been applied in people's daily life.

Speech recognition is to solve machine "understand" a human language technology. As the leading direction of the intelligent computer study and the key technology of man-machine voice communication, speech recognition technology has received extensive attention of national science. Now, with voice recognition technology research breakthroughs, the development of computer and the importance of social life is becoming more and more apparent. Based on speech recognition technology developed has a very wide range of product applications, such as voice-activated telephone exchange, information query, family services, hotel services, medical services, banking services, industrial control, voice communication system, etc., almost into every industry and every aspect of society.

This paper describes the design of specific human voice control player software system based on the MATLAB software, and realizes the application of MATLAB software to control the functionality of the player, voice control mode to identify the specific "open", "closed", "pause" voice command and control, to replace the traditional mouse or keyboard operation switch control the player and play.
