More than one voice option might exist for the Samsung Galaxy S8’s artificial intelligence (AI) system. Samsung appears to be planning a release of a male and female version of the AI. A trademark for the name “Bixby” was discovered earlier this month and is believed to refer to the system.

GalaxyClub has since come across a registration for the name “Kestra,” indicating there are multiple names that may be used for the AI. Kestra seems to be a more feminine name than Bixby.

There’s still a lack of hard evidence connecting either name to the AI, so the name of the system and the voices it’ll use aren’t fully known.
