US 10,706,838 B2 · 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.

Claims13

Dependent claims

A method, performed by an electronic device, of performing speech recognition, the method comprising:

from a first device and a second device receiving a user's voice, receiving first audio data and second audio data comprising the voice;
determining sound quality of each of the first audio data and the second audio data;
selecting at least one audio data from among the first audio data and the second audio data, based on the determined sound quality;
performing speech recognition with respect to the voice, based on the selected audio data;
determining a command corresponding to the voice, based on a result of the speech recognition;
selecting an application for performing the command, from among at least one application, based on the result of the speech recognition;
and
transmitting the command to the selected application.

5 more elements

An electronic device comprising:

a communication unit configured to, from a first device and a second device receive a user's voice, receive first audio data and second audio data comprising the voice;
and
at least one processor configured to determine sound quality of each of the first audio data and the second audio data, select at least one audio data from among the first audio data and the second audio data, based on the determined sound quality, perform speech recognition with respect to the voice, based on the selected audio data, determine a command corresponding to the voice, based on a result of the speech recognition, select an application for performing the command, from among at least one application, based on the result of the speech recognition, and transmit the command to the selected application.
