How can I build voice search for my app on Tizen smart tv similar to youtube?

I am building a voice search feature for my OTT application. However I can’t find any API that Tizen TV SDK exposes me to be able to listen to the user’s voice from the magic remote. I tried a voice search on the Youtube app and it worked.

Please help me know how this voice search flow works!

  1. Solution
  2. APi or Service I can use

Thank all!
