Reconstruct sound using smartphone accelerators? What do you mean? That accelerometers can act as speakers and produce sound? Or they can act as microphones and record sound as numerical data of vibrations etc? Can you point me to any articles or sources?

Tangentially related: Did you know, that it‘s technically also possible to reconstruct sound via smartphone accelerometers and there‘s no restrictions on which apps can use it. Have fun with this info (:

are you saying that a cellphone accelerometer can be used as a microphone? That sounds… interesting. Do you have a source?

I am not the person you are replying to, but if the accelerometers are sensible enough, the vibration of the voice will be picked up by the accelerometer.
Since the sound we make when talking are periodical, it can probably easier to track that periodicity and reconstruct the sound from there.
It’s all my (un)educated guess.

Thanks, I hate it.
