M2 and newer MacBooks have an IMU on-board, which is just a funny way of spelling microphone. Admittedly a very low quality one; I'm not sure if you could pick up understandable speech at the 1.6kHz sample rate Bosch's IMUs seem to support.

Are there examples of using IMUs to get audio data you could point to? A quick search didn't reveal anything.

There's this paper, which made the news at the time I think: https://crypto.stanford.edu/gyrophone/files/gyromic.pdf

And there's this post, which includes an audio clip: https://goughlui.com/2019/02/02/weekend-project-mma8451q-acc...
