语音识别技术可以实现真正意义上的人机对话，但在航海模拟器中还没有得到应用。以GMDSS模拟器中甚高频设备为例，重点设计人机交互界面、操作菜单、数据输入方式等方面，利用Visual Studio 2010进行仿真设备的实现；在研究语音信号、语音识别等关键技术基础上，使用Microsoft Speech SDK开发语音识别功能模块，实现对甚高频仿真设备的语音控制。首次将语音识别技术应用在航海模拟器中，取得了较理想的效果，对于语音技术应用在其他航海仿真系统有较好的借鉴作用。

Speech recognition technology can achieve the man-machine dialogue truly, but it has not been application for Marine Simulator. In this paper, an example of VHF of GMDSS simulator to be given to do a briefly introduce from man-machine interface, menu design and data input, and then implemented it on the Visual Studio 2010 platform. Based on researching the key technology about speech signal and recognition, A speech recognition system developed with Microsoft Speech SDK, and operated VHF simulator by using this system. It is the first time to application speech recognition technology on marine simulator, and achieved a satisfactory results, it has a good reference for the speech technology used in other marine simulator systems.
