Claim 13:
14. A method, comprising:
transmitting, via a network, an audio sample including speech and ambient sounds to a vehicle computer;
broadcasting the audio sample in a vehicle of the vehicle computer;
recording, from the vehicle computer, audio from the audio sample;
recognizing, by the vehicle computer, speech in the recorded audio from the audio sample;
receiving, via the network from the vehicle computer, the recorded audio including the audio sample:
receiving, via the network from the vehicle computer, the recognized speech from the recorded audio;
identifying text of the recognized speech from the recorded audio;
inputting the recognized speech and the identified text of the recognized speech to a machine learning program that outputs whether the recognized speech matches the identified text; and
when the output from the machine learning program indicates that the recognized speech does not match the text, including the recognized speech and the text in a training dataset for the machine learning program;
wherein the machine learning program is trained to output, from the recorded audio, a detection of a vibration from a vehicle subsystem indicating potential maintenance for the vehicle subsystem; and
identifying a variation with the vehicle subsystem based on the output detected vibration from the recorded audio and a vibration predicted by a prognostics model of the vehicle subsystem.
