Go to the Roku website and check out their products and accessories. They sell voice remotes that work with all (most) their Roku TV's. If you buy it from them it has to be paired. Under Settings on your TCL Roku TV, go to Remote and Devices, Pair NEW device and follow the instructions. The pairing button is inside the battery compartment. If you have a Roku voice remote from a Roku player you may be able to pair it, but only some will work your TCL TV.
