A interactive voice response system that automatically adapts to suit the speed at which the caller interacts with the system. The caller interacts with the system utilizing the keypad buttons on a DTMF-type telephone or by speaking verbal instructions over any type of telephone, and hears spoken instructions and information over the telephone in response to those entries. The system is programmed to measure the response times of the caller and adjust the playing speed of the application dialogue's voice messages accordingly using a caller adaptive response algorithm incorporated into the application software of the voice response system. If the caller is responding relatively fast and without error to the voice message prompts, the caller adaptive response algorithm software will gradually speed up subsequent voice message prompts to a preset, reasonable maximum speech rate. If the caller is responding more slowly to the voice message prompts or is making errors in their responses, the caller adaptive response algorithm software will slow down subsequent voice message prompts to a reasonable, preset minimum speech rate. This process continues throughout the application dialogue such that said system is always closely approximating the natural conversational pace of the caller.
