Estonian
Eva Liina Asu, Pire Teras · Journal of the International Phonetic Association · 2009
Estonian belongs to the Finnic branch of the Finno-Ugric language family and is closely related to Finnish. It has about one million native speakers in Estonia and about 150,000 elsewhere in the world. In phonetics, Estonian is probably best known for its three degrees of contrastive quantity: short (Q1), long (Q2) and overlong (Q3).
