Abstract: PURPOSE: A digital voice speed variable reproducing method and an apparatus of the same are provided for repeatedly outputting a voice without any degradation in a voice quality by adjusting a reproducing speed by a user. CONSTITUTION: A microphone(10) converts a voice signal into a certain level electrical signal and receives an external voice signal. A deck unit(12) outputs a voice signal from a storing unit such as a recording tape, etc. and may be a cassette tape recorder, a compact disk player or an AM/FM radio. An analog/digital converter(14) converts an analog signal outputted from the microphone(10) or the deck unit(12) into a digital signal. A sampling unit(16) samples the digital signal converted by the analog/digital converter(14) at a certain sampling period which depends on pre-determined setting inputted external conditions.
