The 28-year-old singer says people never got to hear her original voice, reported Contactmusic.
"Since 'The Fame', 'The Fame Monster' and 'Born This Way', they've been auto-tuning it more, or changing the timbre. They take the vibrato out so you sound like a robot. They really control you especially in the beginning.
"Although it was still my songs, and I still had a lot to say about the production, the vocal was something that they really, really wanted to control. So my vocal presence has been kind of the smallest presence about me for a long time. So everything else becomes the focal point," she said.
"So when I say 'at this point in my career', he's changed my life for me because he's gonna make my art better from this moment on. Because he said: 'Hey, you're so much better than you're even letting yourself be'," she said.
