Abstract
A method for detecting whispered speech of a user of a mobile computerized device, the method comprises: detecting, by the mobile computerized device, whispered speech context; and attempting to detect, by the mobile computerized device and by using whispered speech detection parameters, the whispered speech; and wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech.

A method for detecting whispered speech of a user of a mobile computerized device, the method comprises:
- detecting, by the mobile computerized device, whispered speech context;
- and
- attempting to detect, by the mobile computerized device and by using whispered speech detection parameters, the whispered speech;
- wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech;
- wherein the attempting to detect the whispered speech comprises:
- applying a whispered speech trigger detection process for detecting a whispered speech trigger;
- wherein a detecting of the whispered speech trigger is followed by applying a whispered speech recognition process for detecting the whispered speech;
- wherein the whispered speech recognition process differs from the whispered speech trigger detection process;
- and
- wherein the whispered speech trigger detection process is associated with a power consumption that is lower than a power consumption associated with the applying of the speech recognition process.
A method for detecting whispered speech of a user of a mobile computerized device, the method comprises:
- detecting, by the mobile computerized device, whispered speech context;
- and attempting to detect, by the mobile computerized device and by using whispered speech detection parameters, the whispered speech;
- wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech;
- wherein the detecting of the whispered speech context comprises determining that the mobile computerized device is positioned at a location selected out of a group that consists of a theatre, a cemetery and a library.
A method for detecting whispered speech of a user of a mobile computerized device, the method comprises:
- detecting, by the mobile computerized device, whispered speech context;
- and attempting to detect, by the mobile computerized device and by using whispered speech detection parameters, the whispered speech;
- wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech;
- wherein the detecting of the whispered speech context is responsive to a location of the mobile computerized device;
- wherein the method comprises determining the location of the mobile computerized device based on short range transmitted content received by the mobile computerized device;
- and
- wherein the short range transmitted content received by the mobile computerized device is a targeted advertisement that has a local distribution.
A non-transitory computer readable medium that stores instructions that once executed by a mobile computerized device cause the mobile computerized device to detect whispered speech of a user of a mobile computerized device by:
- detecting, by the mobile computerized device, whispered speech context;
- and attempting to detect, by the mobile computerized device and by using whispered speech detection parameters, the whispered speech;
- and wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech;
- wherein the attempting to detect the whispered speech comprises:
- applying a whispered speech trigger detection process for detecting a whispered speech trigger;
- wherein a detecting of the whispered speech trigger is followed by applying a whispered speech recognition process for detecting the whispered speech;
- wherein the whispered speech recognition process differs from the whispered speech trigger detection process;
- and wherein the whispered speech trigger detection process is associated with a power consumption that is lower than a power consumption associated with the applying of the speech recognition process.
A mobile computerized device that comprises one or more sensors, a microphone, a processor;
- wherein the processor is configured to detect whispered speech context and to attempt to detect, by using whispered speech detection parameters, whispered speech of the user that is sensed by the microphone;
- wherein at least one whispered speech detection parameter of the whispered speech detection parameters differs from at least one corresponding non-whispered speech parameter that is used for detecting non-whispered speech;
- wherein processor is configured to attempt to detect the whispered speech by applying a whispered speech trigger detection process for detecting a whispered speech trigger;
- wherein the processor is configured to apply, following a detection of the whispered speech trigger, a whispered speech recognition process for detecting the whispered speech;
- wherein the whispered speech recognition process differs from the whispered speech trigger detection process;
- and wherein the whispered speech trigger detection process is associated with a power consumption that is lower than a power consumption associated with the applying of the speech recognition process.
