For question about the Speech Assessment Methods Phonetic Alphabet (SAMPA) and its dialects (like X-SAMPA)

The Speech Assessment Methods Phonetic Alphabet (SAMPA) is an ASCII-based phonetic alphabet.

SAMPA covers a restricted subset of IPA sufficient to transcribe the major Eurpean langauges, Arabic, Hebrew, and Thai.

X-SAMPA attempts to cover the whole IPA range.
