Samsung previously described Bixby as "a new way to interact with your phone", and "fundamentally different from other voice agents or assistants in the market".
Samsung told INQ in a statement that Bixby Voice will "expand to more languages globally over time", following its United States launch in June, so it's unlikely the feature will make its way to UK any time soon.
Although Bixby has been hit by delays, early S8 adopters will still be able to enjoy Siri alternatives, with the Android 7.0 enabled Google Assistant onboard.
However, the company made a swift U-turn and announced Bixby availability for United Kingdom users, but said it would be optimised for Korean and American users.
"Key features of Bixby, including Vision, Home and Reminder, will be available with the global launch of the Samsung Galaxy S8 on April 21", Samsung said. However, in a statement given to The Verge, Samsung admits that Bixby's headline feature - voice control - won't be ready in time for when the device ships to United States consumers on April 21.
Bixby, which was introduced in March as Samsung's first step in "revolutionizing the human-to-machine interface", was set to make its debut on the Galaxy S8. Samsung is "proudly" claiming that Bixby is the most intelligent virtual assistant on the market yet, capable of performing tasks that other virtual assistants can not.
So the company did indicate that Bixby may have a slow start, but the lack of one of the most important traits at the very beginning will make it more hard for the new virtual assistant to leave a mark.
