It's been almost three years since Samsung introduced Bixby. Samsung joined the game pretty late, so Bixby Voice naturally doesn't have the robust language support that we see with competing virtual assistants like Google Assistant, Apple Siri, and Amazon's Alexa. Right now, Bixby can speak and understand US and UK English, Chinese, Korean, French, German, Italian and Spanish, and soon, Portuguese will be added to the list as well.
Samsung has started beta tests for adding Portuguese support to Bixby Voice this week in Brazil. Those who are using any of the Galaxy S10 smartphones can take part in the beta. Samsung isn't saying if any other smartphones, like older flagships or the Galaxy Note 10, will be included, although it's possible the beta test will expand to those devices somewhere down the line.
Adding new languages to voice assistants is a time consuming affair, and Samsung would benefit from including more of its user base so that it doesn't take too long to finish completing work on Portuguese support. Not preloading Bixby on budget and mid-range phones for the first year or two was partly the reason why Bixby has been so slow to catch up to the competition, and Samsung would do well not to repeat that mistake when it comes to adding new languages to its virtual assistant.
