X-SAMPA

Vedi anche: International Phonetic Alphabet.

The Extended SAM Phonetic Alphabet (X-SAMPA) is a variant of SAMPA developed in 1995 by John C. Wells, professor of phonetics at the University of London. It was designed to unify the individual language SAMPA alphabets, and extend SAMPA to cover the entire range of characters in the International Phonetic Alphabet.

The result is a SAMPA-inspired recasting of the IPA into 7-bit ASCII.

Notes

• The IPA symbols that are ordinary lower-case letters have the same value in X-SAMPA as they do in the IPA.
• X-SAMPA uses a following backslash as an escape character to create a new symbol. For example O is a distinct sound from O\, to which it bears no relation. (Note that it is a convention among some conlangers to use an asterisk (e.g., O*) instead of backslash).
• X-SAMPA diacritics follow the symbols they modify. Except for ~ for nasalization, = for syllabicity, and ` for retroflexion and rhotacization, diacritics are joined to the character with the underscore character _.
• The underscore character is also used to encode the IPA tiebar.
• The numbers _1 to _6 are reserved diacritics as shorthand for language-specific tone numbers.
