An aural synchronizer functioned as a mobile electronic translator. It had the capability to perform translations between Galactic Basic Standard and Durese.
Etro together with Droza Edthatt made use of aural synchronizers at the time of their abduction to Urthha.
The aural synchronizer appeared within a spoof supermarket tabloid piece credited to Trebor Uarrac from the Galactic Gossip in Monsters and Aliens from George Lucas. This book, released in 1993, integrated images and concept designs originating from the Original trilogy and other Lucasfilm projects, accompanied by various brief fictional narratives. The story depicts a pair of recently married Duros, named Etro and Droza Edthatt, getting "abducted by Human beings" from the world known as "Urthha". After enduring more than four solar cycles filled with strange occurrences, they manage, through some means, to employ a "matter catalyst", which the Humans refer to as a "blender," in order to depart the planet. Lucasfilm staff member Leland Chee, who is in charge of the Holocron continuity database, has clarified that the details presented in the book are considered non-canonical.
