Samsung knows its Bixby virtual assistant needs to be smarter. The company announced version 2.0 of the assistant on Wednesday at its developer conference in San Francisco.

Among the upcoming improvements, Bixby will be able to recognize different people speaking to it. That feature has recently come to the Amazon Echo and Google Home smart speakers, which come with Alexa and the Google Assistant, respectively.
