Everquest II and Star Wars Galaxies players are now able to use Vivox's Station Voice service in-game for free, Sony Online Entertainment announced today.

The service, which will also launch in Everquest in September, allows players to talk to each other through integrated voice chat.

It also provides for moderator controls, through which a user can manage group and user chat activity, including individual volume and mute settings per users.

SOE says it will implement other Vivox services "later this year," such as voice fonts and connectivity with the game's Station Launcher tool. The company also aims to extend these same features to other current titles, as well as future games like The Agency.

John Smedley, president of Sony Online Entertainment, explained, "The integration of Station Voice into these initial games was seamless, and we look forward to incorporating this added gaming experience into other SOE titles, as well as implementing the next phase of features to come soon."
