Pop star Lady Gaga has hit out at recording studio bosses for using voice-adjusting software on her music, insisting she often sounds like a "robot" on her albums.
The Poker Face hitmaker has accused officials at her record label of trying to "control" her early career and blames them for demanding that her singing should be made to sound more "radio-friendly".
She alleges studio staff were ordered to increase the use of pitch-tuning software to correct any imperfect singing during the early days of her career, which left her vocals sounding unnatural.
Gaga tells British magazine Seven, "There's been a part of me that has been quiet for a long time that is now being reawakened, after years of producers and record label people telling me to make my voice sound more radio-friendly.
"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."
