Takes a recording of up to 60 minutes in the language being learned and a learne
Takes a recording of up to 60 minutes in the language being learned and a learner level, and returns words and phrases worth learning — chosen for the level, skipping the most basic ones — each with the base form, translation into the learner's language, word type, an estimated CEFR level, and the exact example sentence from the recording with its timestamp so it can be listened to in context.
