1. A computer-implemented method, comprising:
receiving, at a microphone of a voice-controlled device having an internal speaker and being in an audio mode, first speech input, the voice-controlled device being operatively connected to a first high-definition multimedia interface (HDMI) port of a television, the first speech input requesting at least video content;
determining, by the voice-controlled device, that a video response should be played at the television based at least in part on the first speech input;
playing, by the voice-controlled device in the audio mode, an audio message over the internal speaker, the audio message indicating that the video response will be played at the television;
switching, by the voice-controlled device, to an audio video (AV) mode from the audio mode, the switching to the AV mode comprising sending a control signal to the television, the control signal associated with changing an active input port of the television to the HDMI port; and
sending, by the voice-controlled device in the AV mode, the video response to the television over the HDMI port.
