Hi, I was wondering how one would locate a vowel in the IPA vowel
quadrangle using pd... Of course I would expect the corners of the vowel
to depend on individual characteristics, but I dont know where to start.
Anyone any ideas? Greetings, Ludwig
I'd like to know as well... about two years ago, I made a patch to play
Wikipedia's vowel samples according to three criteria (two [vradio] and
one [tgl]) :
0 1 2 3 4
6 [i][y] [ɨ][ʉ] [ɯ][u]
5 [ɪ][ʏ] [ʊ]
4 [e][ø] [o]
3 [ə]
2 [ɛ][œ] [ʌ][ɔ]
1 [æ] [ɐ]
0 [a][ɶ] [ɑ][ɒ]
And then some more. Personally I'm mostly interested in [iyɪʏeøeœaœəuʊøʌɑ]
(the nonnasals used in my own speech), but I'd like a language-independent
locator too.
Then for example I numbered the above like
001 = 6 0 1 = [ɶ]
200 = 4 0 0 = [ɛ]
511 = 1 1 1 = [ʏ]
531 = 5 3 1 = [ʊ]
The digits are : row number, column number, subcolumn number. I'd add a
fourth number that'd toggle nasals (because I need [ɛ̃̃œ̃ø̃ɑ̃ɔ̃õ] to reproduce
my speech) and perhaps a fifth number that would toggle [ː] but it might
be more appropriate to write them as a pair of identical vowels
(especially as some of them mutate to diphtongs in my speech).
I haven't looked much in the analysis part of it yet. I thought I could
analyse the sound samples, extract their cepstrums, cross-fade them,
resynthesise using a different envelope and tone... but I haven't tried
any of that at all in the end (well, maybe I started trying it and it
didn't work...).
