A two-way voice messaging terminal for communicating with a receiving terminal which may or may not be capable of reproducing a voice message transmitted from the voice messaging terminal. A voice message is digitally encoded and stored in a memory. A receiving terminal selection unit connected to the first memory preferably allows for the selection of the receiving terminal(s) to which the voice message is to be transmitted. The receiving terminal selection unit then receives the stored, digitally encoded voice message and determines whether the selected receiving terminal(s) is(are) capable of reproducing the voice message. If the receiving terminal(s) can reproduce the voice message, the voice message is transmitted to the selected receiving terminal(s). If the terminal(s) is(are) not capable of reproducing the voice message, the voice message is converted into a text message in a speech-to-text converter in the voice messaging terminal and then transmitted to the selected receiving terminal(s). The voice messaging terminal may also have a text-to-speech converter to convert a response text message into a synthesized voice message, the response text message being sent from the selected receiving terminal(s) in response to the voice message transmitted by the voice messaging terminal.
