Voice Search also rolling out to T2100 & T2200 boxes https://support.youview.com/youview-box/software-updates/bt-software-update-32-36-0-3-6-154/
According to here https://support.youview.com/youview-box/software-updates/latest-software-versions/ the rollout to T4000s is complete as stated by @SeanD above.
Works an absolute treat. Nice feature.
I'm not sure that's true. I have enabled Alexa and whilst she can find programmes such as Corrie or Assenders (which we never watch) when I ask her to move to a different channel she's stumped. 'Hmm! I don't seem to know that one' is her reply.
Now if you want to experience a great voice search experience try Sky Q. That system will do just about anything on voice, really top notch.
Can’t say I disagree with you. Other than testing the feature, I haven’t used it. But then this is true of so much automation. It’s there for the sake of being there.
