Abstract
A method for wake word detection during a communication session includes receiving a local audio signal from a microphone of a local communication device, the microphone capturing sound from a local environment of a local communication device, and receiving a far-end audio signal from a far-end communication device on a far-end of the communication session, the far-end communication device connected to the local communication device during the communication session. A first occurrence of a wake sound in the local audio signal is detected, and responsive to detecting the first occurrence of the wake sound in the local audio signal and determining that the far-end audio signal does not contain a second occurrence of the wake sound within a threshold period of time from the first occurrence, activation signal is transmitted to a controller. The activation signal causes a processor associated with the communication device to perform an operation.
