voice-compose

Default to one short reusable timbre sample per speaking character and one VO/narrator sample when narration exists. video-compose keeps actual shot dialogue/VO in the video prompt. Treat audio_result.data.text as downstream speech only for approved final narration/line reads.

Patterns

Follow PROJECT_AGENT.md for context/staging. This skill owns voice prompt + CLI shape.

1. Character voice sample

Triggers: "give / design a voice for [character]", "what does [character] sound like", "voices for all the characters on the canvas".

• Target: any image_result for the person; don't gate on subtype. Read data.local_path before prompt; layer name/role/description on top.

• Call:

  node "$PAI_REPO_ROOT/server/cli/generate_voice.js" \
    --text "<line>" \
    --prompt "<voice design brief>" \
    --source-node-id <character.id>
  

• Prompt describes the voice, not the character:

  [age bracket] [gender], [timbre], [register], [pace], [accent if relevant]. [optional emotional color].

  ✅ "Mid-50s man, gravelly baritone, measured pace, slight rasp from decades of smoking, weary but steady." ✅ "Young woman, bright mezzo, warm, quick and percussive. Slight Southern lilt." ❌ "Detective Morris's voice." — names the character, not the voice. The model needs sound qualities.

• text: 1-3 sentence in-character sample (≤200 chars), not every script line.

• Script breakdowns: one staged call per speaker; preserve labels. Add separate VO/narrator via Pattern 2.

2. Narrator / VO voice sample or final line audio

Triggers: narrator voice, voice-over, "a voice that says X" without character, narration track, or explicit final line-read audio.

• Omit --source-node-id:

  node "$PAI_REPO_ROOT/server/cli/generate_voice.js" \
    --text "<the narration line>" \
    --prompt "<voice design brief>"
  

• Same prompt convention as Pattern 1.
• Reusable VO/narrator anchor: short sample line in narrator style, not full script narration.
• Final narration/line-read: copy approved text exactly into --text; then data.text is source of truth.
