Interactive voice recognition electronic device and method

摘要

An interactive voice recognition electronic device converts a received voice signal to a text, and searches a voice databases to find a matched voice text of the converted text. The matched voice text is taken as a recognized voice text of the voice signal if the matched voice text exists in the voice database. The electronic device obtains a predetermined number of similar voice texts if no matched voice text exists in the voice database. The electronic device converts the predetermined number of similar voice texts to the voice signals, outputs the converted voice signals in turn, and selects one of the similar voice texts as the recognized voice text according to the selection of the user. The electronic device obtains the associated answer text of the recognized voice text in the voice database and converts the answer text to voice signals.
