Conversation practice is the hardest part of language learning to get consistently. Voice AI provides an infinitely patient, always-available speaking partner. This guide shows you how to structure AI language practice sessions for real fluency gains.
WHAT TO LOOK FOR
Start with a language declaration
Begin each session by telling Lucy you are practicing a specific language. 'I am practicing French today — please respond in French and correct my errors' sets the frame immediately.
Use scenarios
Practice specific situations: 'Let us practice a job interview in French', 'I need to practice ordering at a restaurant in Italian', 'Help me practice a business presentation in Spanish.' Scenarios produce the most useful conversational practice.
Ask for corrections
Tell Lucy your error-correction preference: correct inline after each error, wait until the end of a sentence, or just flag errors without correcting. Adjust the frequency to your current level — too many corrections overwhelms beginners.
TLDR:Lucy OS1 speaks French, Spanish, German, Italian, Portuguese, Japanese, Chinese, Korean, and more. Switch to your target language and Lucy switches with you — correcting errors, expanding your vocabulary, and holding conversations at whatever pace you need.

When you do not know a word, describe it and ask Lucy for it. Then ask Lucy to use it in three sentences. In-context vocabulary acquisition is more durable than flashcard memorisation.
