## Description

Text-to-Speech (TTS), voiceover, narration placement/sync, and custom sound effects (SFX) generator. Use when the user wants generated speech from text, wants to add/replace/align narration or voiceover for an existing video/timeline, wants to keep existing voiceover synced after visual retiming edits, needs voice audition/selection, or explicitly wants a newly generated/custom sound effect that is not available in the Sound Effects library.

# 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](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](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:
