PROBLEM TO BE SOLVED: To provide a game machine which enables the adjustment of the volume of sounds output from a speaker to that corresponding to the volume of sounds within a game parlor. SOLUTION: The game machine is provided with a microphone, a speaker, a data conversion means for converting input sounds to data based on an electric signal output from the microphone, a waveform determination means which determines whether the specified waveform pattern is contained in the waveforms of the input sounds from the data generated by the data conversion means, a sound volume measuring means for measuring the volume of the input sounds from the data generated by the data conversion means and a sound volume decision means which determines the volume of the input sounds from the volume of the input sounds measured by the sound volume measuring means after the determination by the waveform determination means that the specified waveform pattern is contained in the waveforms of the input sounds and a sound output control means which carries out a processing of outputting the electric signal to be converted to the output sounds, whose volume is determined by the sound volume decision means, to the speaker.
