基于TTS的实验自主学习系统的实现

在大多数高等教育院校中,电子技术实验学时少、内容多、内容复杂,表现出学生难学、老师难教的现状.利用TTS及单片机技术研制实验自主学习系统,即将教师在课堂上要讲的相关内容(如实验方法、实验步骤等)以文本方式存储,然后系统将文本转换成语音方式输出,播放的内容同时在LCD上同步显示.学生利用本系统在课余时间进行实验可以解决没有教师指导的难题,该系统现在已经应用到模拟电子技术实验中.经过实验表明,该系统取得了较好的应用效果、具有较强实用性和推广性.

Implementation of the Self-Study Experiment System Based on TTS

In most domestic universities,there are limited class hours with massive complicated teaching content for the electronic technology experiments,which makes it difficult for students to learn and for teachers to teach.Using the TTS(text-to-speech) and the single-chip technology,the authors have developed a Self-study Experiment System,which stores all the interrelated contents that teachers will talk about in class,such as experiment methods and experimental procedures,into the system memory using the text mode.Then,the system turns the text messages into voice output,broadcasts the contents,and simultaneously displays them on the LCD.Therefore,the system can overcome the difficulty of the students that no teacher guides them when they do experiments in their spare time.Now,the system has been applied to the analog electronic technology experiments already.The experimental results have shown that the system has a good application prospect,practicability and validity.
