Abstract

A method, performed in an electronic device, for assigning a target keyword to a function is disclosed. In this method, a list of a plurality of target keywords is received at the electronic device via a communication network, and a particular target keyword is selected from the list of target keywords. Further, the method may include receiving a keyword model for the particular target keyword via the communication network. In this method, the particular target keyword is assigned to a function of the electronic device such that the function is performed in response to detecting the particular target keyword based on the keyword model in an input sound received at the electronic device.

8. The method of claim 7, further comprising:

receiving the input sound;

performing the function in response to detecting the particular target keyword in the input sound based on the combined keyword model; and

performing the at least one other function in response to detecting the second particular target keyword in the input sound based on the combined keyword model.

9. The method of claim 1, wherein the keyword model is received in an application file, and further comprising extracting the keyword model from the application file, wherein the function to which the particular target keyword is assigned includes activating the application.

10. The method of claim 1, further comprising receiving a voice tone model associated with the particular target keyword, wherein the voice tone model is adapted to modify a voice tone of speech output by the electronic device.

11. The method of claim 10, wherein the voice tone model is adapted to modify the voice tone of speech that is converted from text, and further comprising:

receiving the input sound;

detecting the particular target keyword in the input sound based on the keyword model; and

if the particular target keyword is detected in the input sound, modifying the voice tone of the speech converted from the text based on the voice tone model associated with the particular target keyword.

12. The method of claim 1, further comprising:

receiving the input sound;

detecting the particular target keyword in the input sound based on the keyword model; and

if the particular target keyword is detected in the input sound, performing the function.

13. The method of claim 1, wherein the function is one of activating a voice assistant, activating a camera, activating a music player, activating a voice recorder, taking a photograph, and unlocking the electronic device.

14. The method of claim 1, wherein the keyword model is non-user specific and includes information to model fewer than all phonemes of a language of the particular target keyword.

15. An electronic device comprising:

a user interface unit to receive input selecting a particular target keyword from a list of a plurality of target keywords;

a download management unit configured to receive, via a communication network, a keyword model for the particular target keyword; and

a keyword setting unit configured to assign the particular target keyword to a function of the electronic device such that the function is performed in response to detecting the particular target keyword based on the keyword model in an input sound received at the electronic device.

16. The electronic device of claim 15, wherein the download management unit is further configured to receive response sound data to generate a response sound indicative of detection of the particular target keyword in the input sound.

17. The electronic device of claim 16, further comprising:
