基于智能语音交互的多媒体阅读辅助系统设计

Design of multimedia reading assistance system based on intelligent voice interaction

传统阅读辅助系统在捕获阅读数据时产生混乱,影响辅助系统的进程且占据过多的利用资源,针对该问题,设计基于智能语音交互的多媒体阅读辅助系统。在硬件设计上,选择微控制器TM4C 123GH6PZ作为主控芯片,构建智能语音交互控制板,以多媒体核心处理芯片作为驱动,设计多媒体设备的连接电路结构。在软件设计上,控制阅读文本的相似度,拓展语音识别引擎为两条通信通道,设定多个语音检测端点,控制阅读数据分帧加窗为文件形式,搭建为音频辅助通信过程。准备系统的开发参数,设定具有文本特征的阅读数据,应用两种传统阅读辅助系统与所设计的阅读辅助系统进行测试,结果表明:所设计的阅读辅助系统的CPU使用率在15%左右,实际占据的利用资源最少。

The traditional reading assistance system generates confusion when capturing reading data, which affects the process of the assistance system and occupies too many utilized resources, and a multimedia reading assistance system is designed based on intelligent voice interaction to address this problem. In the hardware design, the microcontroller TM4C 123GH6PZ is selected as the main control chip to build the intelligent voice interaction control board, and the multimedia core processing chip is used as the driver to design the connection circuit structure of multimedia devices. In the software design, the similarity of the reading text is controlled, the speech recognition engine is expanded into two communication channels, multiple speech detection endpoints are set, the reading data is controlled in frames and windows into file form, and it is built as an audio-assisted communication process. Preparing the development parameters of the system, setting up reading data with text characteristics, applying two conventional reading assistance systems and testing the designed reading assistance system. The results show that the designed reading assistance system has a CPU usage rate of about 15% and actually occupies the least amount of utilized resources.
