Abstract

This invention relates to an interactive voices recognition system and in particular relates to speech recognition processing within an interactive voice response (IVR) system. One problem with speech recognition in an IVR is that two time intensive tasks, the speech recognition and forming a response based on the result of the recognition are performed one after the other. Each process can take up time of the order of seconds and the total time of the combined processes can be noticeable for the user. There is disclosed a method for processing in an interactive voice processing system comprising: receiving a voice signal from user interaction; extracting a plurality of formant values from the voice signal; calculating an average of the formants; locating look ahead text associated with a closest reference characteristic as an estimate of the full text of the voice signal. Thus the invention requires only acoustic analysis of a first portion of a voice signal to determine a response. Since it does not require full linguistic analysis of the signal to convert into text and then a natural language analysis to extract the useful meaning from the text considerable processing time is saved.
