TheExtended Speech Assessment Methods Phonetic Alphabet (X-SAMPA) is a variant ofSAMPA developed in 1995 byJohn C. Wells, professor ofphonetics atUniversity College London.[1] It is designed to unify the individual language SAMPA alphabets, and extend SAMPA to cover the entire range of characters in the 1993 version ofInternational Phonetic Alphabet (IPA). The result is a SAMPA-inspired remapping of the IPA into 7-bitASCII.

SAMPA was devised as ahack to work around the inability oftext encodings to represent IPA symbols. Later, asUnicode 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 aninput method for true IPA.

Summary

[edit]

Notes

[edit]
  • The IPA symbols that are ordinary lower case letters have the same value in X-SAMPA as they do in the IPA.
  • X-SAMPA usesbackslashes as modifying suffixes to create new symbols. For example,O is a distinct sound fromO\, to which it bears no relation. Such use of the backslash character can be a problem, since many programs interpret it as anescape character for the character following it. For example, such X-SAMPA symbols do not work inEMU, so backslashes must be replaced with some other symbol (e.g., anasterisk: '*') when adding phonemic transcription to an EMU speech database. The backslash has no fixed meaning.
  • X-SAMPA diacritics follow the symbols they modify. Except for~ fornasalization,= forsyllabicity, and` forretroflexion andrhotacization, diacritics are joined to the character with the underscore character_.
  • The underscore character is also used to encode the IPAtiebar:k_p codes for/k͡p/.
  • The numbers_1 to_6 are reserved diacritics as shorthand for language-specific tone numbers.
  • TheIETF language tags registry has assignedfonxsamp as the subtag for text transcribed in X-SAMPA.[2]

Since April 2008, the latter is the case of thelabiodental flap, symbolized by a right-hookv in the IPA:. A convention for the labiodental flap does not yet exist in X-SAMPA.
