Wondering why Samsung still hasn't enabled Bixby voice features in English despite promising a launch in the spring? Apparently, it's down to a lack of info. A spokesperson tells the Korea Herald that the company just doesn't have enough "big data" to make its AI-powered voice assistant available in languages besides Korean. It needs that extra knowledge to train Bixby's deep learning system, the Herald says. That's borne out by US beta testing: Samsung says there have been some 'unsatisfactory' responses so far.
