Batad Ifugao is spoken by about 43,000 people, and is also known as Amganad and Ifugaw.
Amganad Ifugao is spoken by about 27,100 people, and is also known as Ifugaw, Mayaoyaw and Mayoyao.
Mayoyao Ifugao is spoken by about 30,000 people, and is also known as Ayangan Ifugao, Batad and Ifugaw.
Tuwali Ifugao is spoken by about 30,000 people, and is also known as Gilipanes, Ifugaw, Kiangan Ifugao and Quianga.
Ifugao is closely related to Bontok and Kankana-ey, and contains loanwords from Ilocano.
This is the united Ifugao alphabet used for all four dialects. The pronounciation varies from dialect to dialect.
