## 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

□ Voices are clearly distinguishable by ear
□ Voices complement (not clash)
□ Power dynamic appropriate for content
□ All voices pass the "would I trust this person?" test
□ Consistent quality/processing across all voices

## Examples

### Example 1: SaaS Product Demo Voice

**Context**: Choosing an AI voice for product demo videos.

**Input**:
> Help me choose an AI voice for our SaaS product demos. Brand is professional but friendly, audience is B2B decision makers (30-50 years old), and we produce 4-5 videos per month.

**Output**:

## Voice Selection: SaaS Demo Videos

### Requirements Analysis
- **Brand**: Professional + friendly (approachable authority)
- **Audience**: B2B decision makers, 30-50
- **Volume**: 4-5 videos/month (~30-60 min total)
- **Implicit needs**: Trustworthy, clear, not salesy

### Platform Recommendation: ElevenLabs Creator ($22/mo)

**Why**:
- Quality matches professional B2B expectations
- Volume fits within plan limits
- Professional voice library
- Room to clone founder voice later if desired

### Voice Selection

**Primary Voice**: Rachel (ElevenLabs)
- Female, American, mid-30s sound
- Professional warmth, clear articulation
- Works for both feature demos and testimonial reads
- Doesn't sound "AI" to most ears

**Alternative**: Josh (ElevenLabs)
- Male, American, early 40s sound
- Authority without stuffiness
- Good for technical deep-dives

### Settings

### Sample Script Test

Before committing, test with representative content:

"DataFlow integrates with your existing tools in minutes,
not months. Here's how: Simply connect your Salesforce instance
using our secure OAuth flow, and we'll automatically map your
custom fields. No IT tickets required."

→ Listen for: Natural flow, clear tech terms, appropriate pace

### Example 2: Multi-Language Brand Voice

**Context**: Expanding content to multiple markets with consistent voice.

**Input**:
> We need to create content in English, French, and Spanish with a consistent brand voice. Same "person" across all languages. Budget is flexible for the right solution.

**Output**:

## Multi-Language Voice Strategy

### Challenge
Maintain consistent brand "character" across languages—not just translation, but the same perceived person speaking.

### Recommended Platform: ElevenLabs Pro ($99/mo)

**Why ElevenLabs for multilingual**:
- Same voice can speak 29+ languages natively
- Preserves tone and character across languages
- Better than separate native voices for brand consistency
- Dubbing feature maintains lip-sync

### Implementation Approach

**Option 1: Design Voice, Use Across Languages**

1. Create perfect English voice using Voice Design
2. Use that exact voice for French and Spanish
3. ElevenLabs handles accent authentically per language

**Voice Design Prompt**:
"A warm, confident voice in the early 30s. Gender-neutral leaning
slightly feminine. Clear, professional articulation with a modern,
international quality. Should sound equally at home in New York,
Paris, or Madrid. Approachable expert energy."

**Option 2: Clone Founder/Spokesperson**

If you have a real person who embodies the brand:
1. Clone their voice (30+ min sample)
2. Use clone for all languages
3. Their "essence" transfers, accent adapts

### Language-Specific Notes

| Language | Consideration |
|----------|--------------|
| English | Base voice, primary development |
| French | Slightly slower pace, French pronunciation patterns |
| Spanish | Choose Castilian vs Latin American variant |

### Quality Control

- Native speaker review for each language
- Check for unnatural pronunciation of brand terms
- Verify numbers and dates sound correct
- Test technical vocabulary
