Analyzes an audio recording (up to 60 min) and returns level-appropriate vocabulary items with base form, translation, word type, CEFR level, and timestamped example sentences from the recording.

How this service works

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.

Output

Returns a list of vocabulary entries, each containing: the base/lemma form of the word or phrase, its translation in the specified output language, the grammatical word type, an estimated CEFR difficulty level, the exact verbatim example sentence from the recording, and the timestamp of that sentence so the learner can navigate directly to it in the audio.
