V --> VgV for all
e.g. in Spanish:
<bueno tiempo> -->
<bueguenogo tieguempogo>, I presume.
(Writing just as a Spanish native speaker
not as phonetist that i'm just amateur) I think that i would transform in
buen tiempo --->
bugueguen tiguiegempogo /buguegen tigiegempogo/
The components in diptongs are
treated independently each one.
In another example:
rosa y azul -->
rogosaga igi agazugul
Would happen that
althought < y >
between vowels has the pronuntiation as a consonant, that is the [j] (with an
up-down circunflex instead of the point), it would be understood as a vowel
sound. But, in Spanish also, if the following word starts
with /i/ then the conjunction < y > use to change to /e/, < e >,
as for example in:
So that allophony for this particular
word -the copulative conjunction- is quite extreem and part explicit. The
disyunctive conjunction also has explicit allophony, as it is /o/ but
becomes /u/ if it's followed by /o/.
