Voice & Sound Effects Generator

Generate voiceovers (TTS) and sound effects. For TTS, choose a concrete provider and voice before calling submit_voice.

When to Use

• Generate voiceover/narration from text
• Create text-to-speech audio for videos
• Add, replace, or redo narration/voiceover for an existing video, timeline, screen recording, slide animation, product demo, B-roll edit, MG explainer, or other visual sequence
• Keep existing narration/voiceover aligned after trimming, speeding up, slowing down, moving, reordering, or replacing the visuals it describes
• Offer and audition TTS voice choices when the user has not picked a concrete voice
• Generate custom sound effects from text descriptions only after checking the Sound Effects library first

TTS (Text-to-Speech)

If the current request has an existing visual target and the user wants narration, voiceover, dubbing, or replacement speech for that target, read references/video-sync.md before drafting new narration, using existing narration text to generate TTS, or placing audio. Do this even when the user did not explicitly say "sync" or "match the visuals"; the existence of a visual target means narration timing and meaning may need to follow on-screen content. Use the normal standalone TTS path only when there is no visual target or the user just wants an audio asset from text.

Also read references/video-sync.md when the timeline already has narration/voiceover and the user asks to change the visuals while keeping that voiceover aligned. This is a sync maintenance task even if no new TTS is needed.

Use submit_voice to create a TTS audio asset. The current MCP tool contract is:
