"Researchers at Dartmouth College have developed new software that uses
the microphone on the iPhone to track and interpret a user's everyday
activity using sound. The software, called SoundSense,
picks up sounds and tries to classify them into certain
categories. SoundSense can recognize completely unfamiliar
sounds and runs entirely on the phone. It automatically classifies
sounds as "voice," "music," or "ambient noise." If a sound is repeated
often enough or for long enough, SoundSense gives it a high "sound
rank" and asks the user to confirm that it is a significant sound and
offers the option to label the sound. In testing, the SoundSense
software was able to correctly determine when the user was in a
particular coffee shop, walking outside, brushing her teeth, cycling,
and driving in the car. It also picked up the noise of an ATM machine
and a fan in a particular room. The results
of the experiments were recently presented at the MobiSys
2009 conference."
