Speaker-dependent voice-activated camera system
View Patent ↗A voice-activated camera system for a computing device. The voice-activated camera system includes a processor, a camera module, a speech recognition module and a microphone for accepting user voice input. The voice-activated camera system includes authorized for only a specific user's voice, so that a camera function may be performed when the authorized user speaks the keyword, but the camera function is not performed when an unauthorized user speaks the keyword.
1 . A speaker-dependent voice-activated system, comprising:
at least one processor;
at least one stored set of voice characteristics coupled to one of the at least one processor, wherein each stored set of voice characteristics identifies an authorized voice of an authorized user;
a plurality of stored keywords coupled to one of the at least one processor, wherein each keyword is associated with one function of a list of functions performed by the system and available for execution in response to voice recognition of the keyword as being from the authorized user;
at least one code segment coupled to at least one of the at least one processor, wherein the at least one code segment is configured to perform the steps of:
receive a voice input from a user;
compare the voice input to at least one of the at least one set of voice characteristics to determine if the voice input matches one authorized voice;
when the voice input matches to one authorized voice, determine if the voice input includes one of the plurality of keywords; and
upon determining that the voice input includes one of the plurality of keywords, execute the function associated with the keyword.
2 . The speaker-dependent voice-activated system of claim 1 , wherein at least one of the performed steps is performed by a first module.
3 . The speaker-dependent voice-activated system of claim 2 , wherein at least one of the performed steps is performed by a second module.
4 . The speaker-dependent voice-activated system of claim 1 , wherein the system further comprises a user interface.
5 . The speaker-dependent voice-activated system of claim 1 , wherein the system further comprises a microphone configured to receive the voice input.
6 . The speaker-dependent voice-activated system of claim 1 , the at least one code segment configured to, when the voice input does not match to one authorized voice, perform an action indicating to the user that the voice input does not match one authorized voice.
7 . The speaker-dependent voice-activated system of claim 6 , wherein the action includes requesting another voice input.
8 . The speaker-dependent voice-activated system of claim 1 , the at least one code segment configured to, when the voice input does not include one of the plurality of keywords, perform an action indicating to the user that the voice input does not include one of the plurality of keywords.
9 . A method for operating a speaker-dependent voice-activated system, comprising the steps of:
receiving of a user voice input by the system, wherein the system includes at least one processor and at least one code segment coupled to at least one of the at least one processor;
comparing the user voice input to at least one of at least one set of voice characteristics stored on the system and coupled to one of the at least one processor, wherein each stored set of voice characteristics identifies an authorized voice of an authorized user;
determining if the user voice input matches one authorized voice;
when the user voice input matches to one authorized voice, determine if the user voice input includes one keyword of a plurality of keywords stored on the system and coupled to at least one of the at least one processor, wherein each keyword is associated with one function of a list of functions performed by the system and available for execution in response to voice recognition of the keyword as being from the authorized user; and
upon determining that the user voice input includes one keyword of the plurality of keywords, executing the function associated with the keyword.
10 . The method for operating the speaker-dependent voice-activated system of claim 9 , wherein at least one of the steps is performed by a first module.
11 . The method for operating the speaker-dependent voice-activated system of claim 9 , wherein at least one of the steps is performed by a second module.
12 . The method for operating the speaker-dependent voice-activated system of claim 9 , wherein the system further comprises a user interface.
13 . The method for operating the speaker-dependent voice-activated system of claim 9 , wherein the system further comprises a microphone configured to receive the user voice input.
14 . The method for operating the speaker-dependent voice-activated system of claim 9 , further comprising the step of, when the user voice input does not match to one authorized voice, the system performing an action indicating to the user that the voice input does not match one authorized voice.
15 . The method for operating the speaker-dependent voice-activated system of claim 14 , wherein the action includes requesting another voice input.
16 . The method for operating the speaker-dependent voice-activated system of claim 9 , further comprising the step of, when the user voice input does not include one of the plurality of keywords, the system performing an action indicating to a user that the user voice input does not include one of the plurality of keywords.
