Abstract

A system and method for validating a wake-up-word. Embodiments of the present disclosure may include receiving, at a first computing device, an audio signal from a second computing device, the audio signal being identified as possibly including a wake-up-word. Embodiments may further include rewinding the audio signal to a starting point of the wake-up-word, to generate a rewound audio signal. Embodiments may also include determining if the rewound audio signal includes the wake-up-word. Embodiments may further include transmitting feedback to the second computing device, wherein the feedback includes at least one of a go-back-to-sleep directive and an accepted detection directive.

Claims

1. A computer-implemented method comprising:

receiving, at a first computing device, an audio signal;

determining if the audio signal possibly includes a wake-up-word;

rewinding the audio signal to a starting point of the wake-up-word, to generate a rewound audio signal; and

transmitting the rewound audio signal to a second computing device.

2. The method of claim 1, wherein the starting point includes a pre-determined amount of silence prior to the wake-up-word.

3. The method of claim 1, further comprising:

transmitting the determined wake-up-word to the second computing device.

4. The method of claim 1, further comprising:

receiving feedback from the second computing device, wherein the feedback includes at least one of a go-back-to-sleep directive and an accepted detection directive.

5. The method of claim 4, wherein feedback includes at least one of an improved pronunciation for the wake-up-word and a threshold setting change recommendation.

6. The method of claim 1, further comprising:

performing a voice biometrics analysis on at least one of the audio signal and the rewound audio signal.

7. The method of claim 1, further comprising:

calculating a confidence score associated with the possible wake-up-word.

8. The method of claim 7, further comprising:

determining whether to transmit the rewound signal, based upon, at least in part, the confidence score.

9. A computer-implemented method comprising:

receiving, at a first computing device, an audio signal from a second computing device, the audio signal being identified as possibly including a wake-up-word;

rewinding the audio signal to a starting point of the wake-up-word, to generate a rewound audio signal;

determining if the rewound audio signal includes the wake-up-word; and

transmitting feedback to the second computing device, wherein the feedback includes at least one of a go-back-to-sleep directive and an accepted detection directive.

10. The method of claim 9, wherein the starting point includes a pre-determined amount of silence prior to the wake-up-word.

11. The method of claim 9, further comprising:

receiving a possible wake-up-word from the first computing device.

12. The method of claim 9, wherein feedback includes at least one of an improved pronunciation for the wake-up-word and a threshold setting change recommendation.

13. The method of claim 9, further comprising:

performing a voice biometrics analysis on at least one of the audio signal and the rewound audio signal.

14. A system comprising:

one or more processors configured to receive, at a first computing device, an audio signal from a second computing device, the audio signal being identified as possibly including a wake-up-word, the one or more processors configured to rewind the audio signal to a starting point of the wake-up-word, to generate a rewound audio signal, the one or more processors further configured to determine if the rewound audio signal includes the wake-up-word, the one or more processors further configured to transmit feedback to the second computing device, wherein the feedback includes at least one of a go-back-to-sleep directive and an accepted detection directive.

15. The system of claim 14, wherein the starting point includes a pre-determined amount of silence prior to the wake-up-word.

16. The system of claim 14, wherein the one or more processors are configured to receive a possible wake-up-word from the first computing device.

17. The system of claim 14, wherein feedback includes at least one of an improved pronunciation for the wake-up-word and a threshold setting change recommendation.

18. The system of claim 14, wherein the one or more processors are configured to perform a voice biometrics analysis on at least one of the audio signal and the rewound audio signal.
