VEHICLE-MOUNTED INSTRUMENT, AUDIO INFORMATION OUTPUT METHOD, AND AUDIO INFORMATION OUTPUT PROGRAM

A voice output unit is mounted on a vehicle. A determiner determines whether or not voice information generated in connection with traveling of the vehicle and output from the voice output unit is information for which an output point of the voice information is specified. A musical piece interval detector detects a time point at which there arrives an interval between musical pieces being reproduced, which are output from the voice output unit. An output controller changes an output time to the arrival time of the interval between musical pieces when the output time, which is specified for the voice information determined by the determiner as not being information for which the output point is specified, arrives at a time point other than the interval between musical pieces.
