US 2017/0365251 A1 · METHOD AND DEVICE FOR PERFORMING VOICE RECOGNITION USING GRAMMAR MODEL

Abstract

A method of updating speech recognition data including a language model used for speech recognition, the method including obtaining language data including at least one word; detecting a word that does not exist in the language model from among the at least one word; obtaining at least one phoneme sequence regarding the detected word; obtaining components constituting the at least one phoneme sequence by dividing the at least one phoneme sequence into predetermined unit components; determining information regarding probabilities that the respective components constituting each of the at least one phoneme sequence appear during speech recognition; and updating the language model based on the determined probability information.

A method of updating speech recognition data comprising a language model used for speech recognition, the method comprising:

obtaining language data comprising at least one word;
detecting a word that does not exist in the language model from among the at least one word;
obtaining at least one phoneme sequence regarding the detected word;
obtaining components constituting the at least one phoneme sequence by dividing the at least one phoneme sequence into predetermined unit components;
determining information about probabilities that the respective components constituting each of the at least one phoneme sequence appear during the speech recognition;
and
updating the language model based on the determined probability information.

A method of performing speech recognition, the method comprising:

obtaining speech data for performing speech recognition;
obtaining at least one phoneme sequence from the speech data;
obtaining information about probabilities that predetermined unit components constituting the at least one phoneme sequence appear during the speech recognition;
determining one of the at least one phoneme sequence based on the information about the probabilities that the predetermined unit components appear during the speech recognition;
and
obtaining a word corresponding to the determined phoneme sequence based on segment information for converting the predetermined unit components included in the determined phoneme sequence into a word.
