Abstract: Implementations are directed to determining an audio delay, of a computing device, by causing an audio data stream to be transmitted to the computing device via a wireless communication channel. The computing device causes audio output generated using the audio data stream to be rendered via speaker(s). The rendered audio output is captured via microphone(s), and the audio delay determined by comparing the captured audio output with the audio data stream. A delay audio segment can be appended to an additional audio data stream transmitted to the computing device, where the length of the delay audio segment is determined using the audio delay. A noise reduction technique can additionally or alternatively be adapted based on the audio delay. Implementations are additionally or alternatively directed to determining if an audio data stream transmitted to a computing device for rendering through speaker(s) driven by the computing device—is actually being rendered.

Abstract: Implementations are directed to causing a computing device to transmit an audio data stream, via a communication channel, to a vehicle computing device of a vehicle. Various implementations include one or more vehicle speakers driven by the vehicle computing device to render audible output. Additionally or alternatively, various implementations include determining whether the audible output is captured by at least one microphone of a vehicle interface device within the vehicle. In many implementations, the vehicle interface device is communicatively coupled to the computing device.
