In the question What happened to the Federation Universal Translator Technology?, it's mentioned that the alien Kalara in Star Trek Beyond speaks a language that standard translator technology struggles to translate. However, we later discover that
Kalara is actually Jessica Wolff, a human Starfleet officer who served aboard the USS Franklin. Presumably, therefore, she also speaks at least one language in common use throughout the quadrant.
What language is she speaking when she's first picked up at Yorktown, and where did she learn it?
