AI Voice Design

> Select and create the perfect AI voice for your content using ElevenLabs, Qwen3-TTS, and other platforms—matching voice characteristics to brand personality and audience.

When to Use This Skill

• Choosing an AI voice for video narration
• Creating a consistent brand voice across content
• Cloning a voice for scalable production
• Comparing voice synthesis platforms
• Designing voice characteristics by description
• Casting multiple voices for different characters/uses

Methodology Foundation

**Source**: ElevenLabs + Qwen3-TTS + Voice Design Best Practices

**Core Principle**: "La voix est 50% de l'impact d'une vidéo"—a poorly chosen or generated voice breaks the illusion. The best AI voice is one listeners don't notice is AI. This requires matching voice characteristics (age, gender, tone, pace) to content type and audience expectations.

**Why This Matters**: AI voice synthesis has reached human-level quality for most use cases, enabling content creation at scale. But the technology is only as good as the voice selection. A mismatched voice undermines content regardless of how natural it sounds.

Instructions

When designing AI voices, follow this methodology:

Step 1: Define Voice Requirements

Before choosing a platform or voice, document what you need.

## Voice Requirements Worksheet

### Brand Alignment
**Brand personality** (3-5 traits):
**Tone of voice** (formal/casual/playful/etc.):
**Existing brand sounds** (if any):

### Audience Match
**Primary audience** (age, context):
**What voice would they trust?**
**What voice would feel authentic to them?**

### Technical Requirements
**Languages needed**:
**Monthly volume** (minutes/hours):
**Real-time needed?** (yes/no):
**Voice cloning needed?** (yes/no):
**Budget** (monthly):

### Content Types
□ Long-form narration (courses, audiobooks)
□ Short-form video (social, ads)
□ Conversational (chatbots, assistants)
□ Character voices (multiple speakers)
□ Localization (same voice, multiple languages)
