Development of sound source separation as hand-free interface for in-vehicle infotainmenet system (IVIS)

In order for in-vehicle infotainment systems (IVISs) to be used using sound detection, it is important for the system to detect a strong and accurate signal. A direct sound source recorded is blended with a mixture of unwanted signal called noise from its surrounding where it does not represent the...
