Finno-Ugric transcription
Finno-Ugric transcription (FUT), or the Uralic Phonetic Alphabet (UPA), is a phonetic transcription or notational system used predominantly for the transcription and reconstruction of Uralic languages. It was first published in 1901 by Eemil Nestor Setälä, a Finnish linguist; it was somewhat modified in the 1970s.
