Laugh detection in Android I'm trying to detect laughs in Android. Something like a score if your laugh is louder or something similar. 

Is it possible to detect laughs maybe through microphone, or facial detection through cameras? Any libraries/APIs or ideas how to achieve this?
Sources of facial detection, on a phone that detects face rests at:

/system/vendor/pittpatt/models
/system/vendor/pittpatt/recognition


I'm using CM13 for my case. They are located there. Maybe facial detection might do that
