PROBLEM TO BE SOLVED: To provide a voice signal adjustment device for suppressing a volume change unintended by a user.SOLUTION: A voice signal adjustment device includes: a level optimization part configured to be switched to an operational state and a non-operational state on the basis of the operation of a user, and to output a first input signal related to a voice whose level is variable as an output signal in a desired level in the operational state, and to output a signal in a level corresponding to the level of the first input signal as an output signal in the non-operational state; and a level adjustment part for adjusting the level of a second input signal based on the output signal from the level optimization part to a level based on the operation of the user. The voice signal adjustment device includes: an input level detection part for detecting the level of the first input signal; a level correction part for correcting the level of the second input signal; and control means for allowing the level correction part to correct the level of the second input signal in a direction of returning to the level of the first input signal on the basis of a difference between the detected level of the first input signal and the desired level when the level optimization part is switched from the non-operational state to the operational state.SELECTED DRAWING: Figure 2 |
