1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to:
transmit, via a network, an audio sample including speech and ambient sounds to a vehicle computer;
broadcast the audio sample in a vehicle of the vehicle computer;
record, from the vehicle computer, audio from the audio sample;
recognize, by the vehicle computer, speech in the recorded audio from the audio sample;
receive, via the network from the vehicle computer, the recorded audio including the audio sample;
receive, via the network from the vehicle computer, the recognized speech from the recorded audio;
identify text of the recognized speech from the recorded audio;
input 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 include 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
identify a variation in 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.
