Subject: Ascii IPA: Klattese
In response to Allan Wechsler's request, here are 2 postings and 3 
versions of an Ascii IPA which I picked up on Usenet Sci.Lang a few 
months ago. Hope they're of use.

Klatt, Dennis H. Review of text-to-speech conversion for English. 
 J.Acoust.Soc.Am 82(3):737-793.

describes 2 transcription systems. One is case insensitive and requires
one or two characters per symbol. Klatt states this system is
"nearly identical to ARPAbet" The other system is a case sensitive one
character system.

Here's the chart from that article.

Actual IPA-ASCII mapping standards don't exist, partly because ASCII
doesn't have enough bits in it, unless you use digraphs for what
are single characters in IPA. However, there is an existing standard
for the ASCII transliteration of *phonemic* transcription of
*English*, using one character per phoneme. 

a = the V in cot I = the V in kit 
c = the V in caught o = the V in coat
 = the V in cat u = the V in coot
e = the V in Kate U = the V in put 
E = the V in pet ^ = the V in cut 
i = the V in Pete x = schwa 

b = the 1st Cons. in bat N = the Last Cons. in king 
d = the 1st Cons. in date p = the 1st Cons. in pat 
C = the 1st Cons. in chat r = the 1st Cons. in rat 
D = the 1st Cons. in that s = the 1st Cons. in sat 
f = the 1st Cons. in fat S = the 1st Cons. in shape 
g = the 1st Cons. in gate t = the 1st Cons. in tat 
h = the 1st Cons. in hat T = the 1st Cons. in thick 
j = the 1st Cons. in jilt v = the 1st Cons. in vat 
k = the 1st Cons. in cat w = the 1st Cons. in wet 
l = the 1st Cons. in late y = the 1st Cons. in yak 
m = the 1st Cons. in mat z = the 1st Cons. in Zach 
n = the 1st Cons. in Nate Z = the med. Cons. in leisure

I'm not a phonetician, just working with the phonetic alphabet.

Not that I know.

Not that I know.

However, there are several Computer-readable Phonetic Alphabets (CPA).
The one I work with is COST-CPA, described in proposal 209TD(87)138 by
Peter Molbaek Hansen, in: report EUR 12023 EN, 1989: Man-Machine
Communication bu Means of Speech Signals, European Research Project COS 209.

In this alphabet, most IPA-characters are assigned to ASCII-characters,
enterable on most keyboards en readable on most terminal screens.
If interested, I can send you more information by mail.

In answer to Allan Wechsler's question, the first 1990 issue
of the Journal of the International Phonetic Association
has an article on the proposed ASCII coding for IPA symbols--
issue 20.1 pp22-26. Since I just found this reference today,
I don't know what it is good for yet, but there *is* now a

As for IPA in ascii, Richard Sproat might have some useful information.

Message 5: IPA on ASCII

Date: Fri, 18 Jan 91 12:15:00 -0800
From: Paul Saka <>
Subject: IPA on ASCII

Altho I do not have a general solution for IPA characters, I would like
to propose the following convention for represennig common English
 /&/ central vowel
 // low front
 /$/ palatal fricative
These symbols are mnemonic: the ampersand is a stylized or modified "e",
just as the inverted "e" is a modified "e"; the at-sign is a modified
"a", just as the ash-symbol is a modified "a"; and the dollar-sign is a
modified "s", just as the esh-sign is a modified s. And for keyboards
that have the cent-sign, modified "c" can stand for the palatal affricate.

Message 6: IPA in Wordperfect

Subject: IPA in Wordperfect
Does anyone know of a source (hopefully cheap) for IPA symbols that can be
called up by Wordperfect 5.0 and can be used with HP laser printers? If so,
please let me know as soon as possible, as I need to produce a camera-ready
text over the next few months. Thanks. Alan Slotkin, English Department, Box
