Speech communications system for a vehicle and method of operating a speech communications system for a vehicle |
摘要 |
A speech communications system for a vehicle includes a microphone system provided in the vehicle interior in order to detect audio information. An interaction manager provides grammar information to a speech recognizer. The speech recognizer provides speech recognition results to the interaction manager. An acoustic echo canceller eliminates portions of the audio information detected by the microphone system. A sound localizer determines a sound source location in the vehicle interior. A method of operating a speech communications system in a vehicle is also provided. An interruptible text-to-speech operation provides a speech output to a user. Voice information is requested from the user for a maximum number of times if insufficient voice information or no voice information is provided in response to the speech output provided by the interruptible text-to-speech operation. The dialog context of an unfinished speech interaction is saved. |
