Southern Alta is spoken primarily in the Sierra Madre of eastern
Nueva Ecija and in nearby coastal areas of
Quezon Province.
History Prior to 1937, no information is available on the early history of the language.
Endangerment of the language Today, Southern Alta risks becoming extinct in the near future. With only 1,000 speakers, or less, the language is categorized as critically endangered. Due to Southern Alta not being a common spoken language in the Philippines, it is likely that the language will soon be lost and will not continue to be passed down, eventually becoming a "dead language". ==Phonology==
