PROBLEM TO BE SOLVED: To surely hear a guide sound, and to ensure even the hearing of an audio sound in a voice output device capable of simultaneously outputting a guide sound signal outputted from an onboard navigation device and an audio signal outputted from an AV apparatus. SOLUTION: When an important path guide sound is outputted, an output from the audio sound is stopped temporarily and recorded previously. The recorded audio sound is outputted by skipping a small sound-volume section until the audio sound catches up a sound at a real time after the important path guide sound is outputted. When the audio sound catches up the sound at a real time, a sound recording is stopped, and a sound output at the real time is restarted. COPYRIGHT: (C)2007,JPO&INPIT |
