IndiaQues. How to use CORTANA in Lumia 625 or any other Windows 8.1 phone? Keeping the search button pressed starts the speech interaction but after saying anything, the program searches any word we say. Is any download needed?
Ans. Language and region/country should be set to US, regional format should be set to "match phone language". Also you need to download the US speech pack.
During these changes your phone will require a restart 1 or 2 times.
To check out if Cortana is now available on your phone go to settings> swipe left> you will see Cortana in the list of applications. If it is visible then click on it and you will see an option to enable Cortana there. That's it after enabling it you will be able to use Cortana on your phone.
