X-SAMPA

The Extended Speech Assessment Methods Phonetic Alphabet (X-SAMPA; /ˌɛksˈsæmpə/) is a variant of SAMPA developed in 1995 by John C. Wells, professor of phonetics at the University of London.[1] It is designed to unify the individual language SAMPA alphabets, and extend SAMPA to cover the entire range of characters in the International Phonetic Alphabet (IPA). The result is a SAMPA-inspired remapping of the IPA into 7-bit ASCII.
