Today, Twenty Thousand Hertz kicks off 2022 with a deep dive into the strange, lovable sonic world of The Sims. Titled "Sul Sul," the episode uncovers the story behind Simlish, the gibberish vernacular of the game's life-simulating franchise — and why artists like Black Eyed Peas, The Flaming Lips, and Katy Perry have all recorded Simlish versions of their hit songs. Host Dallas Taylor begins by exploring the creation of the language with Claire Curtin, The Sims' Designer and Voice Over Director, before speaking with voice actor Krizia Bajos, Lead Composer and Audio Director Jerry Martin, and Sims fanatic Rachael (known online as Rachybop) about the technique behind the perfect Sim vocal.

Claire Curtin, The Sims' Designer and Voice Over Director, opens the episode by explaining the core dilemma the game's creators faced when inventing the language of The Sims: repetition. The in-game dialogue needed to ensure that as players worked tirelessly away at their perfect universe, their ears never became used to what they were hearing — or worse, bored of it. And so, Simlish was born, managing to entirely subvert the structures of language through carefully constructed gibberish. 

Though there are a few official Simlish words — for example, "sul sul" means hello and "dag dag" means goodbye — Curtin reveals that 99.9% of the dialogue in the game is improvised on the spot by voice actors. In allowing the gamer to imagine what the characters might be talking about, the player replaces the gibberish with their own personal experience, making the virtual reality all the more their own. 

Effectively, Simlish has become a unique means of expressing emotion and intent in the world of The Sims, and beyond. Veteran Sims voice actress Krizia Bajos explains how she puts herself in a free-flowing, improvisational mindset when speaking Simlish, while Audio Director Jerry Martin expresses that not just anyone can pull this off. As the game's Lead Composer, he's created both The Sims' sonic aesthetics and coached studio musicians to sing in this gibberish language. As the series grew, artists like Depeche Mode, The Black Eyed Peas, Soulja Boy, Fun., The Flaming Lips, Nelly Furtado, Katy Perry and more re-recorded their own hit songs in Simlish, for use in the games. Both Bajos and Martin agree: for the perfect Simlish, you've got to let go of control. Famously, actor and game show host Drew Carey just couldn't grasp the art — so he restrategized, and decided to write these strange sounds out phonetically. 

It's been more than twenty years since the first Sims game came out, and the series is still going strong. As host Dallas Taylor expresses, "Simlish is just one part of this game, but it's a crucial part. It's a gibberish language where the only meaning comes from the emotions behind the sounds. And that means that anyone can understand it, and anyone can speak it."
