1. An apparatus including an electronic device, the electronic device comprising: a processor comprising: a speech synthesizer; and a speech recognizer including a recognition set and an echo canceller; an analog to digital converter coupled to receive an analog speech input signal and provide corresponding digital speech data to the speech recognizer; a digital to analog converter coupled to receive synthesized speech data from the speech synthesizer and provide a corresponding analog speech output signal; and a memory coupled to provide recorded voice prompt data to the speech synthesizer, the memory comprising: data corresponding to a plurality of recorded voice prompts, wherein an audio input channel is activated to receive the analog speech input signal, wherein the speech synthesizer outputs one of the voice prompts as the analog speech output signal, and wherein after the audio input channel is activated and during the outputting of the voice prompts, the audio input channel receives a user speech input signal, and in accordance therewith, the volume of the analog speech output signal is reduced and the echo canceller is enabled and uses data for said one of the voice prompts from memory to perform echo cancellation on the user speech input signal.
