Following an earlier beta test, the latest PlayStation 5 firmware update is out now, adding 1440 HDMI video output and gamelists (AKA folders), along with some new social features.
In addition to the previously announced features in the beta, the new PS5 firmware update allows players to search for content on YouTube through voice commands. Players can say, “Hey, PlayStation, find [keyword] on YouTube.” This will open the YouTube app and search for what you asked.
This new voice command option is currently available through a preview test, and is limited to the US and UK. English is the only supported language right now.
