Survey on Computer Aided Language Learning using automatic accent assessment techniques

The automatic identification of prosodic events such as pitch accent in English has long been a topic of interest to speech researchers. Applications like Computer Aided Language Learning (CALL) and Computer Assisted Pronunciation Training (CAPT) applications plays an important role in English Learning. We are discussing the different methods to build automatic accent assessment system in which we can convert non native accent to native one. With the use of these algorithms we can detect the pronunciation mismatches in English learning process.
