Yes, Cartman does have a speech impediment. His vocal performance has become so popular that it has gone on to inspire many other similar cartoon characters. Parker voices Cartman in a very distinctive way, making him sound bratty, whiny, and often extremely selfish. He has been voicing him since the show’s debut in 1997 and shows no signs of slowing down anytime soon. Trey Parker is the voice for the iconic character of Eric Cartman on South Park. The final product is then mixed and mastered, giving us the iconic villainous tone of Cartman. The recorded audio is then edited using Pro Tools software, and the pitch is adjusted to make it sound like that of a fourth grader. To make Cartman’s voice, Matt Stone (the voice actor for Cartman) records his dialogue in his normal vocal range, with a childlike inflection. This resulted in a more gentle and less abrasive sound for the character. To avoid long-term damage to his vocal cords, he gradually softened Cartman’s voice over time. The Evolution of Eric Cartman’s VoiceĮric Cartman’s voice changed because Trey Parker found that after a few seasons of doing the same voice for the character, his throat was getting sore from the strain. Trey Parker has done an exceptional job in bringing Eric Cartman to life all these years – and while his voice may have changed slightly over time, it will forever be remembered for its unique qualities that make South Park so special. He also speaks from behind his teeth, pronouncing words such as “tomorrow” as “tuh-muh-ruh” instead of their full pronunciation. It’s also worth noting that Cartman has a slight lisp and tends to jumble letters together when speaking (e.g., saying “ku” instead of “cool”). This is then edited with Pro Tools and altered in pitch to make it sound like that of an elementary school student. To this day, Parker still voices Cartman with his natural vocal range but adds a childlike inflection to it. This was done without any computer manipulation – but as Parker’s throat started to hurt after a few seasons of performing this grueling vocal task, he slowly softened Cartman’s voice over the years.

He then added a layer of fatness to it, creating an unmistakable sound that perfectly embodied the egocentric fourth-grader. To give life to Cartman’s character, Trey Parker began by using his own voice as a base.
