Abstract: A processor receives a broadcast in a vehicle, select audio data from the broadcast, processes the audio data selected from the broadcast, determines a phonetic pattern of the selected audio data based on the processing, selects additional instances of audio data from the broadcast that resemble the selected audio data, processes the additional instances of audio data from the broadcast, determine phonetic patterns of the additional instances of audio data, and selects a plurality of phonetic patterns from the phonetic pattern of the selected audio data and the phonetic patterns of the additional instances of audio data. A transmitter transmits the plurality of phonetic patterns to a server to determine an optimal pronunciation of the selected audio data based on a statistical analysis of the plurality of phonetic patterns and to add the optimal pronunciation of the selected audio data to a database used to recognize speech in the vehicle.

Abstract: An infotainment system of a vehicle includes: a primary intent module configured to determine a primary intent included in voice input using automated speech recognition (ASR); and an execution module configured to, via a first hardware output device of the vehicle, execute the primary intent. A secondary intent module is configured to: based on the primary intent, determine a first domain of the primary intent; based on the first domain of the primary intent, determine a second domain; and based on the voice input and the second domain, determine a secondary intent included in the voice input using ASR. A display control module is configured to display a request for user input indicative of whether to execute the secondary intent. The execution module is further configured to, via a second hardware output device of the vehicle, execute the secondary intent in response to user input to execute the secondary intent.

Abstract: A system and method of changing features of an existing automatic speech recognition (ASR) system includes: monitoring speech received from a vehicle occupant for one or more keywords identifying a feature to remove from or add to the ASR system; detecting the keywords in the monitored speech; and adding the identified feature to or removing the identified feature from from the ASR system.

Abstract: A method for recognizing speech in a vehicle includes receiving speech at a microphone installed to a vehicle, and determining whether the speech includes a navigation instruction. If the speech includes a navigation instruction, the speech may be sent to a remote facility. After sending the speech to the remote facility, a local speech recognition result is provided in the vehicle to the user. The speech sent to the remote facility may be used to provide corrective action. A system for recognizing speech in a vehicle may include a microphone, and may be configured to determine a local speech recognition result from the speech command and determine when the speech command includes a navigation instruction. The system may further include a remote server in communication with the vehicle that receives a sample of the speech command from the speech recognition system when the speech command includes a navigation instruction.
