Abstract: A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input from a user and determining, by the voice-controlled device, that a power state of an AV display device that is coupled to the voice-controlled device is an ON or OFF state. Based on the user intent determined from the speech input and the power state of the AV display, the voice-controlled device sends data to the AV display device to switch the AV display device ON or OFF. The method can further include receiving, by the voice-controlled device, content from a content source location and sending the content to the AV display device via an AV port.

Abstract: A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input, generating an electrical signal having a first gain level that is below a gain threshold for audible detection by a user, transmitting the electrical signal to the speaker and detecting, by the microphone, an audio signal that includes a combination of ambient noise and a probe audio signal, wherein the probe audio signal is output by the speaker based on the electrical signal. The method further includes determining a power level of the probe audio signal and determining a state of the display based on the power level of the probe audio signal.
