AI tool builds entirely new languages, then checks its own grammar
ConlangCrafter creates new languages by building their sounds, grammar, and words in separate steps. The system checks its own work and fixes contradictions, producing more varied and consistent languages than a single AI prompt. The technology could assist fictional world-building and research involving languages with limited written examples. An artificial language with no consonants sounds like a puzzle. A language spoken through colors and tentacle gestures sounds stranger still. ConlangCrafter can build both, while trying to keep every rule, word, and translation consistent. “The idea of ConlangCrafter is: ‘How can we make new languages that have different linguistic features than what we normally see in natural languages?’” said Alper, the paper’s first author and an incoming University of Miami computer science professor. The team has created more than 60 languages and released the code online. Users can also set unusual constraints before generation begins. The system uses large language models to create constructed languages, or conlangs, one layer at a time.
