I asked Sheila, who is from Argentina, if she heard certain pronunciations in this interview that were typically Argentinian.
Here is her comment on los abuelos in the clip below…
I don’t know what it is, but the way she almost skips the S in LOS, identifies her immediately as someone from the Province of Santa Fe, she speaks about it later (acento Santafecino). It’s hard to believe that even though they all heard italian growing up, if you gathered this family, which is spread out through Argentina, they would all probably sound different, they have all picked up the Spanish of the area where they settled.
Understand native Spanish speakers! Here is the full interview: Growing up in an Italian-speaking community in Argentina.
