'Darwin'-a new software was invented by Emiliano Miluzzo and his colleagues of Dartmouth College, New Hampshire.
This new system will recognize an event, such as a specific person's voice, and how the voice may change in different conditions, such as when that person is in a noisy room.
The phones then share this information with other phones that contain the software.
This sharing allowed phones with Darwin to correctly identify which person was speaking with up to 90 per cent accuracy.
This software will help a lot the persons who have the system in their cellphone than those who didn't have the software.
"By relying on the resources around you, you get better results. The idea is to make the sensing process on phones scalable,"said Miluzzo.
He added that Darwin could be used to improve other cell phone applications that rely on sensor data, such as Global Positioning System (GPS).
