SimilarityBoost	0.0-1.0	Higher = closer to original voice
Style	0.0-1.0	Higher = more stylized/exaggerated

    VoiceSettings: settings,

Tips¶

Test with your voice - Presets are starting points. Different voices respond differently to settings.

Consider duration - Longer content benefits from higher stability.
Platform expectations - TikTok audiences expect energy; podcast listeners expect calm.
A/B test - Try different presets and gather feedback.
