Hale championed the importance of under-studied minority languages in linguistic study, stating that a variety of linguistic phenomena would never have been discovered if only the major world languages had been studied. He argued that any language, whether it has a hundred million native speakers or only ten, is equally likely to yield linguistic insight. Hale was also known as a champion of the speakers of minority languages, and not just of their languages, for which his MIT colleague Noam Chomsky called him "a voice for the voiceless".
