PROBLEM TO BE SOLVED: To selectively supply an audio signal recorded on a specified part to a user by selecting the specified recorded part based on punctuation positional information in accordance with the inputted judgement and supplying the audio signal of an unselected recorded part to the user with the volume more suppresive than that of the selected part signal. SOLUTION: A selector signal inputted from a headphone stereo 1 by a remote controller 11 functions as information showing stop positions of respective recorded parts, and then, a DTMF decoder 15 functions as an information input part. Further, a controller 13 functions as a selection part selecting the specified recorded part, and a selector 18 functions as a volume suppression part for suppressing the volume of the audio signal. When the judgement inputted by the user is decided as a right answer as an answer of a question, the controller 13 forms a control signal for releasing a temporary stop state to output it from a signal output part 12. When the connection of the selector 18 is switched to the headphone stereo side 18b, a right answer message is started to be reproduced.
