We know that following groups of syllables
- se, si, sa, so, su
- ce, ci, za, zo, zu
can be pronunced in 3 different ways:
|"s" + vowel||/s/||/s/||/θ/|
|"c/z" + vowel||/θ/||/s/||/θ/|
The question is: approximately how many people in Spain use each of these pronunciations?
I don't ask for Latin America because I know they use "seseo".
