The Burlington Speech Trainer (BST) uses a database based on tens of thousands of recordings of Spanish teenagers, which allows it to recognise and correct the typical errors of this type of speaker while ignoring other non-typical mistakes. Using its Spanish database, the BST listens and identifies the exact sound the student has difficulties with. The Train me button takes the student into a personalised pronunciation course. The pronunciation course helps the student recognise the error, and shows the student how to articulate the sound correctly. The BST then offers a variety of practice activities to perfect the pronunciation of a particular sound, such as minimal pairs differentiation practice and sound discrimination practice.
