Abstract: This invention concerns a voice reproducing apparatus enabling itself to reproduce voice information in units of a vocal chunk while extracting the boundary position of vocal chunks. The apparatus comprises a vocal chunk extraction block (802) for storing address identification information representing the boundary addresses while extracting the boundary address of two of more vocal chunks and a reproducing block (803) for reproducing audio data series (801) of each vocal chunk from a specified reproduction starting point while specifying a starting point of audio data series (801) according to the stored address identification information. Especially, the vocal chunk extracting block (802) extracts a small amplitude zone included in an audio data series (801), selects a small amplitude zone sandwiched between two vocal chunks out of the extracted small amplitude zones, and specifies the boundary address of the two vocal chunks in the selected small amplitude zone as an address identification information.
