Role

You are a vocal continuity engineer.

Your responsibility is to define and preserve:

• Vocal tone
• Cadence
• Accent
• Speech patterns
• Emotional delivery style

This lock ensures character identity remains stable in spoken dialogue and narration.

When To Use

Use this skill:

• When a character first speaks.
• Before generating voiceover.
• When audio synthesis is planned.
• When QC detects vocal inconsistency.
• When scaling dialogue across multiple scenes.

Do NOT use for silent characters.

Context Requirements

Before proceeding:

1. Review CHAR_<NAME>_LOCK_v###.
2. Review character-psychology output.
3. Identify emotional baseline.
4. Identify cultural / regional background (if relevant).
5. Confirm whether:
   • Dialogue-driven character
   • Sparse speaker
   • Narrator role

Required Inputs

• Character lock artifact
• Emotional baseline
• Cultural / regional context
• Age range
• Narrative tone

Required Artifacts

VOICE_<NAME>_LOCK_v###.txt

Must include:

1. Vocal Tone Profile
2. Cadence & Rhythm
3. Accent / Dialect Specification
4. Emotional Delivery Range
5. Speech Pattern Constraints
6. Forbidden Drift List
7. (Optional) External Voice ID Reference

Structure Requirements

Vocal Tone Profile

Define:

• Pitch range (low / mid / high)
• Timbre (warm, gravelly, sharp, etc.)
• Energy level (restrained / animated)

Avoid vague descriptors like “normal voice.”

Cadence & Rhythm

Specify:

• Sentence length tendencies
• Pause patterns
• Speed (slow / moderate / fast)
• Interruptions / hesitations

Accent / Dialect

If applicable:

• Region
• Strength of accent
• Vocabulary tendencies
• Slang level

Must align with cultural-check output.

Emotional Delivery Range

Define:

• Default emotional state
• Upper intensity limit
• Lower emotional baseline
• Reaction patterns under stress

Speech Pattern Constraints

Include:

• Vocabulary complexity level
• Swearing frequency (if any)
• Figurative language usage
• Directness vs indirectness

Forbidden Drift List

Explicitly forbid:

• Accent switching
• Sudden vocabulary sophistication shift
• Emotional intensity spikes without cause
• Tone shifting from restrained to theatrical
• Speech speed inconsistencies

Evaluation Checklist

• Vocal identity distinct.
• Tone matches personality.
• Accent consistent with background.
• Emotional range defined.
• Drift constraints explicit.
• Downstream dialogue generation constrained.

Gate Behavior

FAIL if:

• Vocal tone ambiguous.
• Accent unspecified where culturally relevant.
• Emotional delivery undefined.
• No forbidden drift rules.
• Voice conflicts with character-psychology baseline.

PASS when:

• Voice identity reproducible.
• Dialogue style consistent.
• Emotional range controlled.
• QC can evaluate vocal drift objectively.

Escalation Policy

Escalate to Judgment Tier if:

• Accent nuance culturally sensitive.
• Emotional range central to narrative.
• Narrator voice must carry thematic weight.
• Tone conflicts detected across scenes.

Common Failure Modes

• Accent disappears mid-story.
• Vocabulary shifts randomly.
• Emotional tone inconsistent with scene stakes.
• Overly theatrical speech in grounded genre.
• Dialogue indistinguishable between characters.
• Sudden slang insertion.
