Rosetta stone software for language learning is designed by Rosetta stone Ltd. The title of this software is given in the name of famous ancient artifact found in Egypt. The Rosetta stone is found very helpful to the archeologist to understand the hieroglyphic writing. The researchers were able to decipher the ancient Egyptian by doing the comparison of Greek and Egyptian inscription with the help of this stone.

The Rosetta stone is effective language learning software which uses the combination of text, image and sound to understand the difference while describing the vocabulary terms, grammar and punctuation in an intuitive manner, without any drill or translation. This is an award winning way of describing the language which is known as method of dynamic immersion.

One unit of instructions consists of a lesson which is made with ten groups. The number of lessons in a group increases with the difficulty of the level. Each unit consists of four images with a word or sentence associated with it which is written as well as spoken by the native speaker. Only written words are available for the languages like Latin which doesn’t have any native speaker.

Each lesson has a set of exercise of reading speaking and listening, for the languages which use the Latin alphabets, some writing exercises are also incorporated.

The last lesson of each unit is a revision of previous lessons, and each word described in the previous lesson is represented with an image. The software has no documentation of grammar, only phrase or word index are represented in the form of phrase or word index.
