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.
