No, that would require a precision that's probably still decades away. It could be used to grossly place people and large objects, and notice their movement. Sensing voice would require to monitor vibrations in either the person speaking or anything that vibrates with the emitted sound.
Funnily, there are much easier ways to do that, although they require direct line of vision [1]. Another option would be to measure the vibrations on walls (think glass on the wall, but hitech).
