3. System Overview


In the experiment, the user communicates to the driver by talking through tablets and microphones attached to the rear seat and microphones in the driver's seat. Each conversation is translated into the target language by the Multiple Language Voice Translation platform located on the cloud. By additionally using GPS information, it is possible to select regional dictionaries to improve the accuracy of the system by identifying specific geographical terms and homonym.
