The TranLang III communications package, alternatively referred to as the TranLang III communications module, served as a communication component for droids. The TranLang III module was a standard feature in protocol droid models, for example, the 3PO-series protocol droid.
The TranLang equipped protocol droids with the ability to communicate in six to seven million languages. During the era of the First Order-Resistance War, C-3PO enhanced his TranLang III communications module, enabling him to understand and speak more than seven million forms of communication. On one occasion, C-3PO attempted to communicate with the tauntaun named Murra using a piercing, unpleasant squawk, but his efforts proved futile.
