摘要
为了更好地发挥三维罗经仿真系统的作用,将语音识别技术引入其中。在分析语音信号预处理、特征提取及语音识别解码等关键技术的基础上,利用Speech SDK5.1开发命令控制型语音识别,实现三维罗经仿真系统的语音交互功能。测试结果表明,该语音交互具有较高的识别率;结合语音识别关键技术分析语音交互指令测试结果,得到影响识别率的主要因素,实现了用语音控制三维罗经仿真系统的目的。
The technique of speech recognition was introduced in order to better play the role of simulation system of 3 D compass. Based on the research of the key technologies of speech signal preprocessing,feature extraction and decoding of speech recognition,the Speech SDK5. 1 was used to exploit the command and control speech recognition to realize the speech interaction of the 3 D gyrocompass simulation system. It can be seen from the test results that the speech interaction has a high recognition rate. Combined with the key technologies of speech recognition,the test results of speech interactive instruction were analyzed and the main factors that affect the recognition rate were obtained,so as to control the 3 D compass simulation system by speech recognition.
