## Voice Design Prompts

### Template
"A [gender] voice in their [age range], with a [accent] accent.
The voice is [tone qualities] with [delivery characteristics].
[Additional characteristics or limitations]."

### Examples

**Corporate Explainer**:
"A male voice in his late 30s, with a neutral American accent.
The voice is warm and professional with clear articulation and
measured pacing. Sounds like a trusted advisor, not a salesman."

**E-learning Instructor**:
"A female voice in her early 40s, with a slight British accent.
The voice is encouraging and patient with a natural, conversational
delivery. Sounds like a supportive teacher who makes complex
topics accessible."

**Tech Product Demo**:
"A young male voice in his late 20s, with a West Coast American accent.
The voice is confident and energetic with a modern, casual delivery.
Sounds knowledgeable but not condescending, like explaining to a
friend who's also into tech."

**Luxury Brand**:
"A female voice in her 30s, with a subtle French accent.
The voice is sophisticated and understated with elegant pacing
and restrained emotion. Sounds exclusive but welcoming, never rushed."

### Tips for Better Results
- Be specific about age (not just "young" but "late 20s")
- Describe the feeling, not just mechanics
- Reference the context/listener relationship
- Iterate: try 3-5 variations, pick the best

## Voice Casting for Multi-Speaker Content

### Dialogue Principles

**Contrast**:
- Different pitches (one higher, one lower)
- Different timbres (one warm, one bright)
- Different energies (one measured, one dynamic)

**Cohesion**:
- Similar quality level
- Compatible accents
- Both feel "from the same world"

### Example Cast

**Corporate Training Video (3 voices)**:

| Role | Voice Type | Platform Choice |
|------|-----------|-----------------|
| Narrator | Authoritative female, 40s | ElevenLabs "Charlotte" |
| Employee A | Friendly male, 30s | ElevenLabs "Daniel" |
| Employee B | Energetic female, 20s | ElevenLabs "Elli" |

**Podcast-Style Explainer (2 voices)**:

| Role | Voice Type | Characteristics |
|------|-----------|-----------------|
| Host | Warm male, mid-30s | Conversational, asks questions |
| Expert | Authoritative female, 40s | Knowledgeable, explains |

### Casting Checklist

□ Verify consistency across sample content

## After Selection

□ Document voice settings
