You could also get a sketch map of the keyboard from key press volume, louder means closer, find backspace, model phone position in relation to keyboard position, take it from there.

I'm not good with onomatopoeia but normal keys generally go tack-tack-tack while the spacebar goes tchick-tchick-tchick. It's noticeably different. This could actually prove quite scary since if you know the length of the 'tack', you're basically doing stupidly simple linear cryptanalysis.
