1) I believe that if I use an IOS or ANDROID app I can use it as a VOICE search within the app, I think I point to the channel's search and then use the microphone of the Smartphone/Tablet. I guess the APP does the Voice to text recognition.
2) I STRONGLY suggest that the voice remote of ROKU, allow this. When I am in the channel's search, allow me to Push/Hold the "Microphone" button, and then dictate what I want the APP to search for and have ROKU do the Voice to text recognition.
p.s. What do we do to see wishlist items and vote for them?
