Lua error in package.lua at line 80: module 'strict' not found. The Extended Speech Assessment Methods 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 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.

SAMPA was devised as a hack to work around the inability of text encodings to represent IPA symbols. Later, as Unicode support for IPA symbols became more widespread, the necessity for a separate, computer-readable system for representing the IPA in ASCII decreased. However, X-SAMPA is still useful as the basis for an input method for true IPA.



  • 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 backslashes as modifying suffixes to create new symbols. For example O is a distinct sound from O\, to which it bears no relation. Such use of the backslash character can be a problem, since many programs interpret it as an escape character for the character following it. For example, you cannot use such X-SAMPA symbols in EMU, therefore you need to replace backslash with some other symbol (e.g. an asterisk: '*') when adding phonemic transcription to an EMU speech database.
  • 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.[clarification needed]
  • The numbers _1 to _6 are reserved diacritics as shorthand for language-specific tone numbers.
