Computer-Assisted Listening and Speaking Tutor (CALST)




The Computer-Assisted Listening and Speaking Tutor (CALST) is a pronunciation training platform with listening, pronunciation, and spelling exercises developed by the Norwegian University of Science and Technology. The exercises are demonstrated for Norwegian, but the explanations are equally valid for all languages.

Several target languages have been implemented in CALST: (British) English, (European) Spanish, Italian, Greek, and Norwegian. 

CALST offers exercises for a basic vocabulary of 1000 words and expressions, but the main goal of the platform is not vocabulary learning. CALST helps you to learn speech sounds in the target language that you do not have in your native language and may find difficult. Sometimes, sounds are familiar but can only occur in specific positions (and are difficult to pronounce in positions where they cannot occur in the native language). For this reason, there are exercises for sounds at the beginning and at the end of the word (if possible in the target language, of course).
