An AI language tutor lets you practise a new language by chatting or talking with an AI character, then gives feedback on what you said.
In plain words
The core is a conversation with a language model that plays a character in a set scene, such as ordering coffee. Speaking practice adds speech recognition to turn your voice into text and a synthetic voice to answer. After the chat, the model reviews your replies and suggests improvements. Good products keep people in the loop: Duolingo says humans write the scenarios for its Roleplay feature and it constantly reviews the AI content.
A quick example
Duolingo's Roleplay puts learners in scenes such as ordering coffee at a café in Paris. After the conversation, learners get AI feedback on how accurate and complex their answers were, plus tips for next time.
Where you'll meet it
