Abstract
Extraction of articulatory factors from an acoustic signal to distinguish between different languages and further identify the original accent of a foreign speaker. Previous language identification systems require identification of the individual phonemes which is not ideal for interactive voice response systems which do not have speech recognition capability. A method of determining a language set for use in an interactive voice response system including the steps of providing a plurality of samples from a voice signal, calculating a first and second format frequency for each sample, calculating a first factor based on the average first and second format frequency for the plurality of samples, finding a nearest matching reference to the first factor, and selecting a corresponding language set to the nearest matching reference.
