A data communication terminal, such as a cellular telephone, capable of synthesizing speech. The data communication terminal can establish a communication session with a base station over a transmission facility implementing a voice channel and a data channel. The data communication terminal includes a speech synthesizer engine that receives from the remote entity a signal transmitted over the data channel and that conveys the vocal tract characteristics of the message to be delivered as a spoken announcement. The base station generates the signal containing the vocal tract characteristics from a text-based signal of the message to be synthesized. The invention also extends to a base station that can convert the text based message to be synthesized into a signal containing vocal tract characteristics and that sends the signal to a remote terminal over the data channel.
