Abstract
Voice-interfaced, in-vehicle assistance includes receiving a voice-based query from a user in the vehicle, and then determining at least one of a user emotional state, user expertise level and speech recognition confidence level associated with the voice-based query. A text-based query may then be derived from the voice-based query, and used to search a help database for answers corresponding to the voice-based query. At least one response is then provided to the user in the form of voice-based assistance in accordance with at least one of the user emotional state, user expertise level and speech recognition confidence level.
Claims26
A method for providing voice interaction in a vehicle, the method comprising the acts of:
- receiving, by a voice interface server, a voice-based query from a user in the vehicle;
- determining, by the voice interface server, an emotional state for the user based on a detected valence and arousal level associated with the voice-based query;
- deriving, by the voice interface server, a text-based query from the voice-based query;
- searching, by the voice interface server using the text-based query, a help database for at least one response to the voice-based query;
- and
- providing, by a voice interface server, the at least one response to the user in the form of voice-based assistance in accordance with the emotional state of the user.
A computer program product, comprising:
- a processor readable medium having processor executable code embodied therein to provide voice interaction in a vehicle, the processor readable medium having:
- processor executable program code to receive a voice-based query from a user in the vehicle,
- processor executable program code to determine an emotional state for the user based on a detected valence and arousal level associated with the voice-based query,
- processor executable program code to derive a text-based query from the voice-based query,
- processor executable program code to search, using the text-based query, a help database for at least one response to the voice-based query, and
- processor executable program code to provide the at least one response to the user in the form of voice-based assistance in accordance with the emotional state of the user.
