The Pimsleur programs provide a method of self-practice with an expert teacher and native speakers in lessons specially designed to work with the way the mind naturally acquires language information. The various components of language -- vocabulary, pronunciation and grammar -- are all learned together without rote memorization and drills. Using a unique method of memory recall developed by renowned linguist, Dr. Paul Pimsleur, the programs teach listeners to combine words and phrases to express themselves the way native speakers do.
