I'm looking for articles about the effects of tonal crowding in intonational languages (tone truncation, tonal compression, schwa epenthesis...). If you've published anything about this subject, I'll be grateful if you let me know.
Paolo, I have tonal crowding in Pescara, two pitch accents having to be aligned with the same (nuclear) syllable, the outcome being anticipation of the first to the pretonic syllable.
I remember reading about a comparative (I think English/Dutch or English/German) work on final crowding, the outcome being truncation in one language, compression in another...as soon as I find the reference I'll tell you
