Comparison of ASCII encodings of the International Phonetic Alphabet

The

Kiel Convention of 1989, and the vowel symbols again in 1993.[1]
Systems devised before these revisions inevitably lack support for the additions they introduced.

Only language-neutral systems are discussed below because language-dependent ones (such as ARPABET) do not allow for a systematic comparison.

PHONASCII George D. Allen at Purdue University 1988 1988 Not a direct mapping of the IPA. Segments are separated by spaces, and diacritics by commas. [4]

UCLA Phonological Segment Inventory Database (UPSID) Ian Maddieson at the University of California, Los Angeles 1984 ? Presented here is the scheme used for representing phonemes in the database of phonological inventories. Consequently, it is not designed for transcription of multiple segments and does not have symbols for values not found phonemically in the languages sampled. [7]

IPA Numbers
. Some of the IPA symbols to which a system lacks a corresponding symbol may still be represented in that system by use of a modifier (diacritic), but such combinations are not included unless the documentation explicitly assigns one for the value.

Notes

  1. ^ a b c d e f g h i j k l In Worldbet, these combinations are given as merely proposed for values "for which no machine-readable coding has yet been proposed".
  2. uvular approximant
    is represented by R in PHONASCII.
  3. ^ a b c L represents either a voiceless alveolar lateral fricative, a velar approximant, or a velarized alveolar lateral approximant in the Usenet IPA/ASCII transcription.
  4. ^ a b c! represents either an alveolar or palatal click in the Usenet IPA/ASCII transcription.
  5. ^ a b - represents either retracted or "velarized or pharyngealized" in Millar & Oasa's system.
  6. ^ a b ¿ and ¡ are not part of ASCII, but are nonetheless proposed as encoding advanced and retracted tongue root, respectively, in Worldbet.
  7. ^ . represents either raised or palatalized in Millar & Oasa's system.
  8. ^ a b * represents either non-syllabic or extra-short in Millar & Oasa's system.
  9. ^ )) representing a tie bar is placed after both segments, as in ts)), in Branner's system.
