Best Practices
Write Naturally
Write as you speak. Use contractions, natural phrasing, and conversational language. Avoid overly complex sentences that are difficult to deliver naturally.
Provide Clear Direction
Whether using text, images, or video, give clear guidance about desired voice characteristics, emotion, and delivery style. The more specific, the better.
Match Voice to Content
Consider your content type. Corporate narration needs clarity and professionalism. Character voices need personality. Audiobooks need sustained engagement without listener fatigue.
Combine Input Types
You can combine inputs! Provide text with an image for mood-matched narration, or add audio reference with video for style-consistent voiceover.
Generate Multiple Takes
Create several versions and choose the best performance. Just like human voice actors, AI generates variations—use this to your advantage.
Test in Context
Always test voice content with its intended context—with music, sound effects, or against video. What sounds great in isolation may need adjustments in the final mix.
