Best Practices

Choose the Right Voice: Match the voice personality to your content type - professional content benefits from Brian or Daniel, while conversational content works better with Rachel or Sarah
Optimize Stability Settings: Use higher stability (0.7-1.0) for consistent narration, lower stability (0.3-0.5) for more dynamic, expressive speech
Language Detection: The model automatically detects the input language, but for best results with mixed-language content, keep each request in a single language
Use Context for Continuity: For long-form content, use previous_text and next_text parameters to maintain natural flow between segments
Speed Adjustments: Slower speeds (0.7-0.9) improve clarity for educational content, while normal to slightly faster speeds (1.0-1.2) work well for casual content
