# Audio Intelligence

> Turn speech into actionable insights with translation, summarization, entities, chapters, sentiment and more

Audio intelligence turns raw speech into structured, useful data on top of transcription. Once the words are captured, these features help you understand, organize, and act on the content — from instant translation to key-point summaries, entity detection, chapter markers, or emotions analysis.
