You can use voice control if the device you use has a microphone and uses Amazon Alexa (Fire TVs) or Google Assistant.

Either press the microphone button or activate the device with the codeword (e.g. Alexa, Echo, Hey Google...).

The following commands are then available:

Play / Resume / Play (to start playback from the overview or to resume from a paused recording)

Pause (to pause recordings, timeshift cannot be activated with this function)

Next (advances to the next channel on Live TV, or by 5 minutes on recordings)

Back (Switches to the previous channel for Live TV, and back by 5 minutes for recordings)

x minutes/seconds forward/backward (jumps the specified time within a recording, e.g. 5 minutes forward)
