You would see a second tile called Voice Control next to Mobile Devices
in Settings Connected Devices
You haven’t missed much. It only seems to allow a search you still have to use the remote to select the programme you want from the search list. Also doesn’t allow switching channels or power options. Still needs more work.
BT did say last week
Roll out of the voice control feature to BT TV customers set top boxes starts nationwide from today and runs until mid-December
I believe it enables a hands free search.
Not got this update as yet. I always seem to get updates to my boxes a few weeks after it comes out.
Hopefully though time Alexa voice search will improve. I do like use Amazon on my Amazon Echos.
Got the update today. I like it. Saves time searching for a show. Ok that’s all you can do for now but I’m sure more features will come soon with BT Alexa integration.
