Talkinn is a mobile application designed to improve English speaking skills. Talkinn, which has a curriculum structure based on CEFR standards, allows students to consolidate the gains they have made in the lessons. Talkinn processes the voice it receives from the user by converting it into text, and also transmits the text it receives from the database by speaking it back to the user. In addition, Talkinn connects to Open AI and other language models, allowing users to have voice conversations with artificial intelligence within certain limits.
