Choosing Voices

- Your cloned voices — Custom voices you've created
Filter by: gender, age, accent, use case (narration, conversational, news, etc.)
Controlling Output
Stability — How consistent the voice stays:
- Low stability = more expressive, variable (good for storytelling)
- High stability = more consistent, predictable (good for narration)
Similarity Boost — How closely it matches the original voice:
- Higher = more accurate to the original
- Lower = more natural-sounding but less precise
Style Exaggeration — Amplifies the voice's emotional characteristics
Speaker Boost — Enhances clarity and presence
Text Formatting Tips
- Use punctuation for natural pauses: commas, periods, ellipses
- CAPITALIZE for emphasis (use sparingly)
- Add "..." for dramatic pauses
- Use paragraph breaks for breathing pauses
- Spell out numbers and abbreviations for consistent pronunciation
- Add pronunciation guides in parentheses for unusual words
Output Formats
- MP3 (default, good for most uses)
