AI Voiceover & Auto-Captions

# AI Voiceover & Auto-Captions Make your [Motion Studio](#/help/studio-motion-timeline) videos work with the sound off and add a professional narration — no microphone needed. ## AI voiceover Generate a **voiceover** from text: 1. Write the script. 2. Pick a **voice** and adjust the **speed**. 3. Generate — the narration drops onto an audio track in the [timeline](#/help/studio-motion-timeline). ## Auto-captions Auto-generate **captions** from the video's audio (including your voiceover) in several **languages**. Captions render on screen so the message lands even when the video plays muted in a feed — which is most of the time on social. ## Polish Pair voiceover with **royalty-free music** and **sound effects** from the [stock library](#/help/studio-stock-media), then [export to video](#/help/studio-video-export) and [post it](#/help/studio-social-posting).
