ABSTRACT:
A data output apparatus judges whether or not sound data that has not yet been outputted has been accumulated. When a judgment is made that there is no accumulation of sound data that has not yet been outputted, the data output apparatus reads already-outputted sound data that was outputted previously and saved, and reproduces (outputs) sound based on the read sound data. Since it is possible to reduce occurrence of abnormality such as sound interruption in the data output apparatus such as an IP telephony terminal apparatus, a lowering of communication quality such as voice quality can be prevented.
