Suspending noise cancellation using keyword spotting |
摘要 |
Aspects of the disclosure provide suspension of noise cancellation at a noise-cancelling device using keyword spotting. In one aspect, a predetermined word or phrase can be spotted within an utterance received at the noise-cancelling device, and in response, noise cancellation can be suspended or otherwise terminated. The predetermined word or phrase can be specific to an end-user that utilizes the noise-cancelling device and/or a person that interacts with the end-user. In another aspect, interaction between an operator and the noise-cancelling device can be monitored after noise cancellation is suspended, and based at least on such interaction, a model for keyword spotting can be refined. In certain aspects, noise cancellation at the noise-cancelling device can be suspended or otherwise terminated in response to receiving a suspension directive via an electronic non-audio signal, for example, from a peripheral device. In other aspects, the noise-cancelling device can resume noise cancellation in response to a control signal. |

1. A method, comprising:
receiving a first external audio signal from a microphone of a noise-cancelling device; determining that the first external audio signal does not comprise a keyword corresponding to suspension of noise cancellation; generating a noise-cancellation signal for cancelling the first external audio signal; causing a speaker of the noise-cancelling device to generate audio corresponding to the noise-cancellation signal; receiving a second external audio signal from the microphone of the noise-cancelling device; determining that the second external audio signal comprises the keyword corresponding to suspension of noise cancellation; facilitating presentation of at least a portion of the second external audio signal at the noise-cancelling device by suspending noise cancellation for at least the portion of the second external audio signal; determining that a defined interaction with the noise cancelling device occurred, the defined interaction corresponding to an event to resume noise cancellation; and resuming the noise cancellation for at least a second portion of the second external audio signal. |
