ABSTRACT:
Electronic apparatus such as a cordless phone, the electronic apparatus includes detection means for detecting the error of received data and at least two speech buffers as speech buffers for temporarily storing the received voice data. In case the electronic apparatus is in a position where it can communicate with a repeater and a base unit, the electronic apparatus stores the voice data transmitted from the base unit into one speech buffer and stores voice data transmitted from the repeater into the other speech buffer, and uses the voice data of a lower error rate. This maintains high speech quality. In case the electronic apparatus roams from a second wireless network formed around the repeater to a first wireless network formed around the base unit, smooth roaming is provided without degrading the speech quality by using the voice data of a lower error rate stored in either of the two speech buffers, even when the conversation state is gradually degraded and more errors are detected in the received data.
