Abstract

A method for voice triggering, the method may include coupling, by an interface of a voice trigger sensor, the voice trigger sensor to a computer; receiving, by the voice trigger sensor, from the computer configuration information; configuring the voice trigger sensor by using the configuration information; coupling, by the interface, the voice trigger sensor to a target device during a voice activation period; receiving, by a processor of the voice trigger sensor, during the voice activation period, input signals; applying, by the processor, on the input signals a voice activation process to detect a voice command; and

at least partially participating in an execution of the voice command.

Claims

configuring the voice trigger sensor by using the configuration information;

coupling, by the interface, the voice trigger sensor to a target device during a voice activation period;

receiving, by a processor of the voice trigger sensor, during the voice activation period, input signals;

applying, by the processor, on the input signals a voice activation process to detect a voice command; and

at least partially participating in an execution of the voice command.

2. The method according to claim 1 wherein the applying of the voice activation process comprises applying user independent voice activation.

3. The method according to claim 1 wherein the coupling of the voice trigger sensor to the computer occurs during a training period;

wherein the configuration information metadata comprises a training result that is generated by the computer during the training period;

wherein the applying of the voice activation process comprises applying, by the processor, on the input signals a training based voice activation process while using the training result to detect the voice command.

4. The method according to claim 3, comprising generating, by a microphone of the voice trigger sensor, first detection signals, during the training period, in response to first audio signals outputted by a user;

sending, by the interface the detection signals to the computer; and

generating, by the microphone the input signals during the voice activation period.

5. The method according to claim 1, comprising receiving the input signals from the target device.

6. The method according to claim 1, comprising wirelessly coupling the voice trigger sensor to at least one of the computer and the target device.

7. The method according to claim 1, comprising detacheably connecting the voice trigger sensor to at least one of the computer and the target device.

8. The method according to claim 1, comprising operating the voice trigger sensor in a first power consuming mode before detecting the voice command and to operating the voice trigger sensor in a second power consuming mode in response to the detection of the voice command;

and

wherein a power consumption related to the second power consuming mode exceeds the power consumption related to the first power consuming mode.

9. A voice trigger sensor comprising an interface, a memory module, a power supply module, and a processor;

wherein the interface is adapted to couple the voice trigger sensor to a computer and to receive configuration information;

wherein the voice trigger sensor is adapted to be configured in response to the configuration information;
