Anomids wearing vocalizer masks
A translation device, known as a vocalizer mask or electronic mask, was designed to be worn on the face. Its purpose was to enable species who couldn't speak Galactic Basic, or other commonly used languages in the galaxy, to communicate.
Because Anomids lacked the necessary vocal cords, vocalizer masks were a typical tool for them. The masks worked by turning the subtle motions of the wearer's jaw and throat muscles into understandable Basic.
In a similar fashion, electronic masks used by the Qieg mimicked the vocal apparatus of Humans. This allowed them to reproduce the necessary vocal ranges for communication. This was essential, as their own language consisted of a combination of chirps, clicks, and body language, making it difficult for them to converse with Humans otherwise.
