What to do if a voice command is not recognized
If your spoken phrase is not captured correctly, follow the on-screen prompts to try again. Make sure you are speaking naturally – there is no need to speak any slower or louder than you do in a normal conversation. Also try not to over-pronounce syllables or words. A clear and direct command works best.
With push-to-talk voice, try holding your handheld remote 2 to 3 inches from your mouth. If you have a tabletop remote, you should be no more than 2 to 3 feet away.
When using hands-free voice, speak in the direction of your remote and not your TV, and keep your remote nearer to you (within 10 to 12 feet) than it is to your television. You want it hearing you over noise from your TV. Also, be sure to use a clear and direct "Hey Roku...". For examples, check out the tutorial video about using hands-free voice commands.
If voice searches are not working to your satisfaction, remember that you can also use Roku Search with the on-screen keyboard.
- Tip: If you notice a long delay from when you say "Hey Roku" to when your voice command is recognized, try turning on Fast Start in the Power menu.
