Abstract: A system and method of recognizing speech in a vehicle. The method includes receiving a voice command at the vehicle via a microphone in the vehicle, and obtaining a recognition result from speech recognition performed on the received voice command. The recognition result may represent the voice command and be indicative of any of two or more available vehicle commands. The method may further include selecting one of the two or more available vehicle commands based on a secondary characteristic and an attribute of the selected one of the vehicle commands. The system may be implemented as vehicle electronics that include a microphone located within the vehicle and configured to receive a voice command from a user located within the vehicle, and a controller in communication with the microphone. The controller may be configured to perform speech recognition on the voice command and obtain a disambiguated recognition result.

Abstract: A system and method of adjusting digital audio sampling used with wideband audio includes: performing audio sampling on an analog audio signal at an initial sampling rate and an initial bit rate over a wideband audio frequency range; generating a digital audio signal based on the audio sampling; detecting a qualitative error rate between the analog audio signal and the digital audio signal; and decreasing the initial sampling rate, the initial bit rate, or both for sampling subsequent analog audio when the qualitative error is below a threshold.

Abstract: A method for classifying a road surface being traversed by a vehicle. The method comprises receiving one or more electrical signals each representative of a vibration detected by a sensor carried by the vehicle. The method further comprises identifying, for at least one of the received electrical signals, a pattern in the detected vibration represented by that/those signal(s), and matching the identified pattern to one of one or more known patterns, wherein each known pattern corresponds to a respective road surface classification. The method further comprises classifying the road surface in accordance with the road surface classification corresponding to the known pattern matching the identified pattern. A system comprising one or more sensors carried by the vehicle that is/are configured to detect a vibration, and a pattern classification system for performing the methodology described above, is also provided.
