Sofia Vergara revealed on Harry Connick Jr.’s talk show that she spent “so much money” on speech lessons when she first joined the film industry. She said, “I spent so much money when I decided I was going to act. I’m like, ‘I’m moving to Los Angeles, I’m gonna hire the best speech coach. I can’t understand why Salma Hayek and Penelope Cruz can’t learn how to speak perfectly. I’m gonna do it!’”
She also explained how her son, Manolo, grew increasingly frustrated with her as she kept pronouncing words wrong while the two would run lines together. She added, “He would run lines with me. And he’d say, ‘Mom, I just corrected you, like, two seconds ago and you said the word again wrong.'”
After some self-reflection, Sofia realized that she was who she was — accent and all. She told WWD, “When I would go to auditions I would get super self-conscious of what I was saying, and I couldn’t concentrate on the acting. I was just concentrating on the pronunciation. One day I said, ‘This accent is never going to change … I’m going to keep trying the way I am and, if it doesn’t work, I’ll go back to the Latin market.’”
