PROBLEM TO BE SOLVED: To suppress the generation of unnecessary voice data generated by stopping a CPU clock when silence data are reproduced.SOLUTION: A voice reproduction device 100 to which a clock and voice data are supplied, and which reproduces an analog voice signal analog-converted from the voice data by using the clock, includes: a data comparison apparatus 104 for generating a clock stop signal when the voice data are equal to a threshold value or close to a zero value rather than the threshold value; an output data generator 114 for generating fadeout data which gradually decreases the voice data in a zero value direction, according to the clock stop signal; an output switching control portion 115 for outputting a switch signal which switches the voice data to the fadeout data, according to the clock stop signal; and a CG portion 107 for stopping the clock according to the clock stop signal. |
