PROBLEM TO BE SOLVED: To correct input voice of a user in an abnormal state into input voice in a normal state. SOLUTION: An operator depresses a reference registration button 141 of a telephone set and inputs an optimum voice to a handset 105 in advance to register the voice to a reference value storage section 121. When the operator starts the processing, the operator depresses a confirmation button 142 and inputs the voice from the handset 105 to register the voice to a measurement value storage section 122. A correction value storage section 123 stores a level difference between the reference voice registered in the reference value storage section 121 and the input voice stored in the measurement value storage section 122. A central control section 101 reads the data stored in the correction value storage section 123, displays a difference between the data and the reference voice on a display section 103, the central control section 101 obtains the difference between both the input voice and the reference voice for the comparison between them and an adder 114 and level correction sections 1091-109n to correct the input voice. |
