Kind Code:
A1
Abstract:
Disclosed are tone compensation device and method for an earset. A tone compensation device (method) for an earset, according to the present invention, is characterized by: extracting, in a parameter extraction unit, phase and amplitude parameters for each frequency from a voice signal transmitted from an in-ear microphone and an out-ear microphone; comparing, in a parameter comparison unit, the extracted phase and amplitude parameters for each frequency of the in-ear microphone and the extracted phase and amplitude parameters for each frequency of the out-ear microphone, respectively; and compensating, in a parameter compensation unit, for parameters having differentials between measurement values by means of the phase and amplitude parameter value for each frequency of the out-ear microphone.
