【摘要】：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。
[Abstract]:Because the voice communication is greatly affected by the environment, the traditional voice communication control system can not meet the needs of users, and the control quality is low. Therefore, the remote wireless network speech communication control system is constructed. The speech recognition module in the system collects the speech signal by using the CG6565 speech card, and carries on the noise reduction processing to it. After noise reduction, the speech signal is converted into a digital signal which is easy to process, and the characteristic parameters of the digital signal are extracted. The speech recognition module recognizes the characteristic parameters, adjusts and measures them to form the speech folder, and feedback the speech folder to the remote wireless network control module. The remote wireless network control module carries on a series of processing to the speech file in the speech folder, the processed speech file is transferred to the user's hand, realizes the system to the user's equipment remote voice control. The software gives the target function of the speech communication signal and the calling code of the objective function. The experimental results show that the designed system has high control efficiency and accuracy, and the overall control quality is high.
