Abstract: An embodiment an infotainment system for an automobile includes a navigation system, an entertainment system, an audio output device and a control system coupled to the navigation system, the entertainment system and the audio output device. The control system controls access by the navigation system and the entertainment system to the audio output device and includes a conversation recognizer that determines if a conversation is being conducted. The control system of this embodiment varies operation of the audio output device in the event a conversation is being conducted.

Abstract: A method and system can control a speech recognition system in a vehicle. The method includes monitoring adaptive feature data about interactions between a user and the speech recognition system. The method includes determining a first group of samples of the adaptive feature data and creating a control chart based on the first group of samples. The control chart includes a control limit. The method further includes determining a second group of samples of the adaptive feature data after creating the control chart. Furthermore, the method includes calculating an arithmetic mean of each sample of the second group of samples to determine a sample mean, comparing the sample mean to the control limit in order identify unexpected performance of the speech recognition system. The method includes adjusting the speech recognition system based on the identified unexpected performance if the unexpected performance is identified.

Abstract: Systems and methods for arbitrating spoken dialog services include determining a capability catalog associated with a plurality of devices accessible within an environment. The capability catalog includes a list of the plurality of devices mapped to a list of spoken dialog services provided by each of the plurality of devices. The system arbitrates between the plurality of devices and the spoken dialog services in the capability catalog to determine a selected device and a selected dialog service.

Abstract: A method of speech recognition in a vehicle. Audio including noise and a speech signal representative of an utterance from a user is received via a microphone, and a signal-to-noise ratio (SNR) for the received audio is calculated using a processor. It is determined whether the calculated SNR is greater than a predetermined SNR. If so, then a noise distribution is identified for addition to the received audio, and noise corresponding to the identified noise distribution is injected into the received audio to produce noise-injected audio including the speech signal.

Abstract: A speech recognition system is provided. The speech recognition system includes a speech recognition module; a plurality of domain specific dialog manager modules that communicate with the speech recognition module to perform speech recognition; and a speech interface module that that communicates with the plurality of domain specific dialog manager modules to selectively enable the speech recognition.
