About the Butters Stotch voice

Butters Stotch is one of the main supporting characters of the animated series South Park, created by Trey Parker and Matt Stone. He is a sweet, naive and endlessly optimistic fourth grader, often the target of his friends' pranks and his strict parents' groundings. Butters also appears in South Park video games, and in the show's feature film, and he has a recurring alter ego, the would-be supervillain Professor Chaos.

The voice is soft, light and high-pitched, with a childlike sincerity. Delivery is gentle and eager, with a quick, bouncy pace when Butters is excited and a wavering, hesitant quality when he is nervous or upset. Expect cheerful politeness, innocent phrasing and a slightly wide-eyed, earnest tone, with sudden squeaks of worry or delight.

To get good results on voicechange.io, you can record or upload speech and hear it transformed, type text to hear 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 this voice, speak or write in a bright, friendly and slightly bashful way. Short, simple sentences with plenty of enthusiasm work best, and clear, steady audio with little background noise helps the result sound clean.

Voice details

Tips for the best Butters Stotch result

This model is centred around 260 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) is shifted a full octave up (the maximum), 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 Butters Stotch 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.
