Rosetta Stone is proprietary computer-assisted language learning (CALL) software developed by Rosetta Stone Inc. Both its title and logo refer to the Rosetta Stone, an artifact inscribed in multiple languages that helped Jean-François Champollion to decipher Ancient Egyptian hieroglyphs. The company is headquartered in Arlington County, Virginia.
The Rosetta Stone software uses a combination of images, text, and sound, with difficulty levels increasing as the student progresses, in order to teach various vocabulary terms and grammatical functions intuitively, without drills or translation. They call this the "Dynamic Immersion method." According to the company, the software is designed to teach languages the way first languages are learned.
