Abstract
Systems and methods are described for determining whether to activate a voice activated device based on a speaking cadence of the user. When the user speaks with a first cadence the system may determine that the user does not intend to activate the device and may accordingly not to trigger a voice activated device. When the user speaks with a second cadence the system may determine that the user does wish to trigger the device and may accordingly trigger the voice activated device.
Claims20
A method for avoiding inadvertent triggering of a voice capable device, the method comprising:
- detecting a voice input comprising a trigger word;
- and
- in response to detecting the voice input comprising the trigger word:
- determining a cadence of the voice input;
- identifying a user associated with the voice input;
- retrieving, from a profile of the user, a speaking cadence of the user;
- determining whether a difference between the cadence of the voice input and the speaking cadence of the user is less than a threshold value;
- in response to determining that the difference is less than the threshold value, refraining from triggering the voice capable device;
- and
- in response to determining that the difference is not less than the threshold value, triggering the voice capable device.
A system for avoiding inadvertent triggering of a voice capable device, the system comprising control circuitry configured to:
- detect a voice input comprising a trigger word;
- and
- in response to detecting the voice input comprising the trigger word:
- determine a cadence of the voice input;
- identify a user associated with the voice input;
- retrieve, from a profile of the user, a speaking cadence of the user;
- determine whether a difference between the cadence of the voice input and the speaking cadence of the user is less than a threshold value;
- in response to determining that the difference is less than the threshold value, refrain from triggering the voice capable device;
- and
- in response to determining that the difference is not less than the threshold value, trigger the voice capable device.
