;;; Commentary:

;; This is a new input method for IPA characters and diacritics, which follows
;; the conventions of Praat, a GPLed program for phonetic analysis.
;;
;; This input method is much more complete than the current ipa.el.

 "International Phonetic Alphabet input method.
This follows the input method of the phonetic analysis program
Praat (http://www.fon.hum.uva.nl/praat/).

For most of the codes, the first letter tells you the most
similar letter of the English alphabet.  The second letter can be
t (turned), c (capital), s (script), r (reversed), - (barred or
retracted), or / (slashed).  One symbol (ɛ) is a phonetic version
of a Greek letter.  The codes for ə, ɤ, ʊ and ɞ are abbreviations
for schwa, ram's horn, horseshoe, and kidney bean.

For most of the codes, the first letter tells you the most
similar letter of the English alphabet.  The second letter can
be t (turned), c (capital or curled), s (script), - (barred),
l (with leg), i (inverted), or j (left tail).  Some phonetic
symbols are similar to Greek letters but have special
phonetic (f) versions with serifs (ɸ, β, ɣ) or are otherwise
slightly different (θ, χ).  The codes for ŋ (engma), ð (eth),
ʃ (esh), and ʒ (yogh) are traditional alternative spellings.
The retroflexes have a period in the second place, because an
alternative traditional spelling is to write a dot under
them.  The code for ɾ is an abbreviation for fishhook.
