вот абзац из статьи о Ти-Пэйне с сайта ЭмТиВи

"Once he gets offstage, Pain doesn't slow down - he has a functional studio on his tour bus, and has been recording and producing for E-40 ("E-40 did like three songs"), Chris Brown and more. On Brown's upcoming single "Kiss Kiss," - a T-Pain production - he uses the Auto-Tune audio-processor effect he's made popular again in recent years. T is cool with Brown using the voice enhancement but says he doesn't appreciate anybody else trying to emulate his style."

"Pain says he was inspired almost three years ago to use the Auto-Tune by Teddy Riley, the pioneering king of New Jack Swing, who used a vocoder."
