PROBLEM TO BE SOLVED: To provide an audio generation apparatus capable of adjusting a gain of output audio according to loudness of ambient noise so that the output audio is not audible unnaturally for a listener. SOLUTION: An utterance unit dividing section 13 divides an output sentence into utterance units, and an output audio data forming section 14 stores an audio data for expressing audio of each utterance unit in an audio data reproduction section 17. A correction timing control section 23 repeats the sequential processing steps of: issuing an instruction of correction application to a correction application section 22; instructing utterance unit audio output to an audio data reproduction section 17; and waiting a report of audio output termination from the audio data reproduction section 17. When the audio data reproduction section 17 receives the utterance unit audio output instruction, the audio signal is reproduced from the audio data for expressing the audio of each stored utterance unit and output, and the audio output termination is reported. The correction application section 22 sets a gain of the audio signal in an amplifier 18 according to power of the ambient noise at that time, according to the correction application instruction.
