Abstract
A method, which is performed by an electronic device, for obtaining a speaker-independent keyword model of a keyword designated by a user is disclosed. The method may include receiving at least one sample sound from the user indicative of the keyword. The method may also generate a speaker-dependent keyword model for the keyword based on the at least one sample sound, send a request for the speaker-independent keyword model of the keyword to a server in response to generating the speaker-dependent keyword model, and receive the speaker-independent keyword model adapted for detecting the keyword spoken by a plurality of users from the server.
Claims22
A method, performed by an electronic device, for obtaining a speaker-independent keyword model associated with a keyword designated by a user, the method comprising:
- receiving at least one sample sound from the user indicative of the keyword;
- generating a speaker-dependent keyword model associated with the keyword based on the at least one sample sound;
- after generating the speaker-dependent keyword model associated with the keyword, sending, to a server, a request to obtain the speaker-independent keyword model associated with the keyword;
- receiving, from the server, the speaker-independent keyword model;
- and
- selecting one of the speaker-dependent keyword model and the speaker-independent keyword model to detect the keyword based on a type of keyword or a function associated with the keyword.
An electronic device, comprising:
- a sound sensor configured to receive at least one sample sound indicative of a keyword designated by a user;
- a keyword model generator configured to generate a speaker-dependent keyword model associated with the keyword based on the at least one sample sound;
- and
- a keyword model management unit configured to:
- send a request to obtain a speaker-independent keyword model associated with the keyword to a server after the speaker-dependent keyword model associated with the keyword is generated;
- receive the speaker-independent keyword model;
- and
- select one of the speaker-dependent keyword model and the speaker-independent keyword model to detect the keyword based on a type of keyword or a function associated with the keyword.
