Audio-based teaching system developed by Michel Thomas, a language teacher in the USA. It was originally done in person, although since his death it is done via recorded lessons. he method focuses on constructing long sentences with correct grammar and building student confidence. There is no listening practice, and there is no reading or writing. The courses are deliberately taught by non-native speakers.

The instruction is done entirely in the student's own language, although the student's responses are always expected to be in the target language.languages at some point in a sentence or utterance, is a commonly used communication strategy among language learners and bilinguals. While traditional methods of formal instruction often discourage code switching, students, especially those placed in a language immersion situation, often use it. If viewed as a learning strategy, wherein the student uses the target language as much as possible but reverts to their native.

 Language for any element of an utterance that they are unable to produce in the target language, then it has the advantages that it encourages fluency development and motivation and a sense of accomplishment by enabling the student to discuss topics of interest to him or her early in the learning process before requisite vocabulary has been memorized.
