ELECTRONIC DEVICE, INFORMATION TERMINAL SYSTEM, AND METHOD OF STARTING SOUND RECOGNITION FUNCTION

An on-vehicle device can simultaneously connect smart phones provided with a sound recognition function through short-distance wireless communications. The on-vehicle device determines whether a specific keyword for starting the sound recognition function of the smart phones is included in an utterance sound of a user. When the keyword is included, the on-vehicle device selects the smart phone identified with the keyword, and transmits a sound signal of the utterance sound to the selected smart phone.
