Season 25 of South Park is finally underway, and although fans worldwide are excited to see what kind of hilarity the new episodes bring, there has seemingly been some concern over the voice of Stan Marsh. Some detail-oriented fans noticed a supposed change in the character's vocal inflection during one of its recent episodes, titled "The Big Fix," which aired on Feb. 9, 2022, causing a few to speak out about it online.

Some took to Twitter in the wake of it all to air out their worries about one of South Park's most beloved characters. "Stan Marsh’s voice sounds a bit off tonight in this new episode. Or is it just me?" wrote one user.

"Stan's voice is deeper; has anyone noticed?" Chimed in another Twitter user.

"First Mackey, and now Stan's voice is acting up. What's going on?" added in a third. Clearly, this is something that many people picked up on when tuning into the episode.

South Park co-creator Trey Parker is still listed as the actor who voices Stan on the show, so we can rule out a change in casting for the character immediately. An old South Park Q&A session revealed that the show utilizes the audio program Pro Tools to work on the vocals for each character. When the show first started, Trey used no technological help to alter his voice, but that changed as time went on.
