已经观察到，现代重工业受到诸如高温、高压等危险工作环境的困扰，这些危险工作环境对人类操作员的生命构成严重威胁。最常见的例子是钢铁厂和矿山，它们每年都报告有巨大的生命损失。因此，需要开发一种系统，任何人员都可以使用该系统来控制过程，而不会使自己暴露于任何类型的普遍工作危险。本文介绍了一种远程语音控制和安全系统（RNTH），以解决上述问题。这是一个系统，可以控制任何过程（例如，开关直流电机的实验目的）从世界任何地方通过发声适当的命令到移动的电话。该系统的硬件包括一个GSM手机连接到TI TMS C6713 DSP入门套件通过立体声音频电缆。远程位置的授权操作员使用他的GSM手机连接到位于过程现场的该系统。系统提示操作员进行访问认证（安全功能），一旦通过认证，用户就会通过发出适当的预定义命令（例如启动和停止电机）来控制工厂操作。DSK工具包执行用于访问认证的真实的时间说话人识别和用于解码语音命令的语音验证。系统软件在Code Composer Studio平台上用ANSIC语言开发。
It has been observed that modern heavy industries are plagued with hazardous working environments like high temperature, high voltage etc. that pose a severe threat to the life of a human operator. Most common examples are steel plants and mines which report huge losses of life every year. Thus, there is a need to develop a system which any human personnel can use to control a process without exposing himself to any type of prevailing work hazards. This paper describes a remote voice control and security system (RVCS) to solve the above problem. It is a system that can control any process (e.g. switching ON/OFF a dc motor for experimental purposes) from anywhere in the world by vocalizing appropriate commands into a mobile phone. The hardware of the system comprises of a GSM handset connected to a TI TMS C6713 DSP Starter Kit via a stereo audio cable. An authorized operator at a remote location uses his GSM handset to connect to this system located at the process site. The system prompts the operator for access authentication (security feature) and once authenticated the user controls the plant operation by voicing the appropriate predefined commands (e.g. starting and stopping a motor). The DSK kit carries out real time speaker recognition for access authentication and speech verification for decoding the vocal commands. The software of the system has been developed in ANSIC in Code Composer Studio Platform.
