One of the reasons why the Samsung Bixby release has been delayed is because Samsung was having problems with getting the system to learn a few other languages and just when we thought that Samsung might be getting close to solving the issue, new reports now claim that Samsung still working on finding a solution.
Those that have tested out the Samsung Bixby quickly reported that despite everything that Samsung did, the system still had trouble understanding the user. Instead of picking up on what you are saying, the system will pick our keywords and try to guess what you are saying.
Samsung is still trying to work things out but we do not know how long more the users will have to wait before they can enjoy a Siri-like Bixby. As of now, Siri and Alexa from Amazon are clearly the winners.
