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.

Detection of TV state using sub-audible signal

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.

Voice-controlled multimedia device

Devices and methods are provided for dynamically switching states of remote control devices. A remote control device may receive voice data from a user, send the voice data to another device which may pass the voice signals to a server. The server may determine instructions associated with responding to the voice signals and send the instructions to the other device, which may convert the instructions to remote control commands. The other device may send the commands along with state information to the remote control device, allowing the remote control device to emit commands determined by the other device and to map other command signals to possible inputs which the remote control device may receive.
