ChickyTutor (https://www.chickytutor.com/) allows you to practice a language with a vocal AI tutor, with corrections and feedback on pronunciation.

Choice of target language and language of instruction from 70 languages.
Three levels.
Three modes: Guided (explanations in the language of instruction), Conversation (only in the target language) or Journey (chapters with podcast generation possible).

The AI tutor analyzes the voice and via its avatar signals a useful improvement and then invites to reformulate.

Three additional tools: writing with translation and corrections, fill-in-the-blank exercises, placement test and listening comprehension podcasts.
Flashcards (in the menu at the top right) can be created.
A library of public podcasts is available.

Free in a limited version of 10 minutes per day.
