摘要： Methods and apparatus are provided for diagnosing a vehicle. In one embodiment, a method includes: initiating, by a processor, a recording of a noise by at least one microphone based on user selection data from a user of the vehicle; receiving, by the processor, audio signal data based on the recording; generating, by the processor, vector data based on the audio signal data; processing, by the processor, the vector data with at least one trained machine, by the processor, learning model to determine a classification of the noise; predicting, by the processor, an action to be taken based on the classification; and storing, by the processor, the audio signal data, the classification, and the action in a datastore.

摘要： 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.

摘要： 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.
