Anonymous:I'm very confused after listening to audios from different websites!
For me, I've always read the hard D and T sounds in these words instead of J and CH sounds. Have I aways been wrong?
Take a two syllable word that has a form: CV[t/d]u, CCV[t/d]u, V[t/d]u, etc where the stress falls on V.
In this pattern, t and d get weakened or go thru lenition or get affricated.
udu: none that I know of
In lento, you can delete the "wuh" syllable, you get "wuh" because of "ua" cluster. This is called sonorant gemination.
Let me explain with one word actual:
'æktʃə-al (affrication thanks to the structure explained above)
'æktʃəwəl (sonorant /w/ gemination)
'ækʃəwəl (deletion of /t/ in some dialects, lento tempo)
'æktʃəl (in the fast/casual speec/allegro tempo/lower register:synope of the sonorant, its called degemination)
'ækʃəl (deletion of /t/ in some dialects, masks vs mass)
you can apply the similar processes on these words: mutual, ritual, individual, sexual, intellectual, manual.
The point is this: your typical pronunciation books don't go this far. And speech you hear can be analyzed this way, with the help of intonemes and preintomenes.
People are waiting to help.
