CA 2062425

An arrangement providing voice activated prompt interrupt for a voice messaging system. The exemplary apparatus includes a telephone line interface, amemory device, a processor, a prompting device and a recording device. Once a call is established at the interface, the processor causes the prompt to be played and simultaneously the incoming signal to be sampled. An echo estimate is determined, subtracted from the incoming signal and a determination is made if incoming speech is detected. If incoming speech is detected, the prompt is stopped and the buffered incoming signal is directed to the recording device.
