About the Cartman voice

Eric Cartman is one of the main characters of South Park, the long-running animated comedy series created by Trey Parker and Matt Stone. A fourth-grader in the Colorado mountain town of the same name, he is famous for his loud opinions, his elaborate get-rich-quick schemes and his endless selfishness. Cartman has also appeared in the South Park feature film and in several video games based on the show, and his catchphrases have become part of pop culture.

Cartman's voice is that of a child: high-pitched, nasal and full of attitude. The delivery is brash and sing-song, with sudden jumps from smug and whiny to furious shouting. The pace is quick and punchy, with exaggerated emphasis on certain words and a petulant, stubborn edge. Expect a cartoonish, over-the-top character voice rather than a natural, neutral one.

On voicechange.io you can record or upload speech and hear it come back as Cartman, type text to have it spoken in this voice, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it yourself. For the best results, speak clearly and with plenty of energy: short, punchy lines with strong emphasis and attitude suit this character well. When typing text, use exclamation marks and short sentences to bring out the bratty, dramatic delivery.

Tips for the best Cartman result

This model is centred around 210 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) is shifted about 10 semitones up, and a typical higher voice (around 210 Hz) isn't shifted, since it already fits. Gaps under 4 semitones are left alone, and shifts stop at one octave. If the result sounds strained, nudge the slider one or two steps back toward your own voice; for song covers, keep it at 0, +12 or −12 so the vocal stays in key. How pitch works.

  • Record in a quiet room with no music in the background; noise is the main cause of robotic-sounding results.
  • Perform the line the way Cartman would say it. The model copies your timing and emotion, only the voice changes.
  • For song covers, pick a track with one clear lead vocal and little reverb.
