远程无线网络语音通信控制系统设计

Design of remote voice communication control system for wireless network

由于语音通信受环境的影响较大,导致传统的语音通信控制系统无法满足用户需求,控制质量较低。因此,构建远程无线网络语音通信控制系统,系统中的语音识别模块利用CG6565语音卡进行语音信号的收集,并对其进行降噪处理。降噪后的语音信号被转换成便于处理的数字信号,并将数字信号的特性参数提取出来。语音识别模块对特性参数进行识别、调整和测量后组成语音文件夹,并将语音文件夹反馈到远程无线网络控制模块。远程无线网络控制模块对语音文件夹中的语音文件进行一系列的处理,处理后的语音文件被传输到用户手中,实现系统对用户设备的远程语音控制。软件给出了语音通信信号的目标函数,以及该目标函数的调用代码。实验结果表明,所设计的系统具有较高的控制效率和控制准确率,控制质量总体较高。

A remote speech communication control system for wireless network was established to eliminate the environmen tinfluence in the voice communication and satisfy the users′ requirements and improve the control quality. The CG6565 voice card is adopted in speech recognition module of the system to collect the speech signal and carry out the noise reduction processing.After the noise reduction,the speech signal is converted into digital signal easy to process,and the feature parameters of the digital signal are extracted. The feature parameters are identified,adjusted and measured by the voice identification module to form a speech folder,which is fed back to the remote wireless network control module. The remote wireless network control mod?ule is adopted to process the speech files in the speech folder. The processed audio files are transmitted to the user,by which the system can implement the remote voice control to the user′s equipment. The objective function of the voice communication signal and the calling code of the objective function are given by the software. The experimental results show that the designed system has high control accuracy and efficiency,and its overall control quality is high.
