A:Answer The TCL Roku TVs are specifically designed to be used with the TCL Roku remote that comes with it. However, you can download the free Roku app on your smartphone or tablet to use with your TCL Roku TV. By using the app you can use voice search, voice control, and experience private listening. However, voice search is not designed to be used within individual streaming channels, but rather with the operating system and general system searches. Hope this helps!
