声再生装置。[Claims for Utility Model Registration] A memory that stores digitized audio data, an arithmetic circuit that demodulates the audio data read from this memory, a register that stores the arithmetic results of this arithmetic circuit, and In an audio reproduction device comprising a digital-to-analog converter that converts the output of a register into an analog signal, and a speaker, an audio level detection means detects when the output content of the register is related to a predetermined audio level or higher. and, at the start of the playback operation, the audio data is read from the memory at a faster rate than the normal playback rate, and after the audio level detection means detects the audio data, the audio data is read out from the memory at a predetermined amount higher than the audio data currently being read from the memory. 1. An audio reproduction device comprising: control means for re-reading previous audio data at a normal reproduction rate.
