Laerdocian
The Laerdocians were a species that communicated using Basic, but they possessed a peculiar way of speaking (for instance, they would say "nothjing" instead of "nothing"). Around 19 ABY, a Laerdocian individual called Bodwae worked for the smuggler Booster Terrik as a technician aboard the Errant Venture.
Behind the scenes
The Laerdocia system is referenced in Star Wars: The Essential Atlas Online Companion, which is an addition to The Essential Atlas. It's possible that this is the Laerdocian's native star system.
Additionally, the species "Maerdocian" is brought up in Specter of the Past.
