PRIORI KNOWLEDGE, CANONICAL DATA FORMS, AND PRELIMINARY ENTRENTROPY REDUCTION FOR IVR

Abstract:

Apparatus and methods for interactive voice recognition. The apparatus and methods may include a canonical phrase derivation engine configured to derive canonical phrases from voice data. The apparatus may include an input engine configured to parse utterances. The apparatus may include a knowledge extraction engine to disambiguate the utterances into words, form a sequence from the words, extract context from the sequence, pair the sequence with a phrase of the canonical phrases, merge the sequence and the phrase to form a hybrid phrase, vectorize the hybrid phrase into a vector, and feed the vector into a non-linear classification engine to determine an intent corresponding to the utterances.
