Abstract:
1. A voice correction device comprising: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, detecting a response from a user; calculating a first acoustic characteristic amount of an input voice signal and a second acoustic characteristic amount of an input signal different from the voice signal; outputting an acoustic characteristic amount of a predetermined amount when having acquired a response signal due to the response from the detecting; storing input response history information in which the presence or absence of a response detected by the detecting, the first acoustic characteristic amount, and the second acoustic characteristic amount are associated with one another; extracting input response history information including values corresponding to a value of the first acoustic characteristic amount and a value of the second acoustic characteristic amount, respectively, calculated by the calculating; calculating a correction amount for the first acoustic characteristic amount on the basis of the extracted input response history information; and correcting the voice signal on the basis of the correction amount.
