PROBLEM TO BE SOLVED: To provide a voice compensation system that can reduce the sense of incongruity when compensating the voice. SOLUTION: This voice compensation system 100 has, a microphone 26 placed at the listening position, variable filters 16, 14, 38 to predict the guide voice signals outputted from the microphone 26 and the ambient noise signals when the guide voice signals are inputted and the guide voice from a loudspeaker 40 reaches the microphone 26, and a voice compensation filter 10 and a loudness compensation gain-calculating section 12, to correct the sound pressure of the guide voice outputted from the speaker 40 by using the compensation gain set up from the average power of the guide voice signals and the average power of the ambient noise predicted by the variable filters.
