How do I make an AI voiceover sound more human and less robotic?

To make an AI voiceover sound more natural, start by writing conversational scripts with shorter sentences and natural phrasing. Before you generate speech in Firefly, you can preview a word or phrase you’re not certain about by selecting it clicking the Play button in the toolbar. Then you can fix pronunciation, add pauses and emotion tags, or go to the Speech Settings panel to adjust speed and pitch.

What should I do if an AI voice sounds unnatural in long scripts?

If an AI voice starts sounding unnatural in long scripts, you can break the text into shorter sections and generate audio in chunks to maintain consistency. Before you generate, you can select words or phrases and preview them by clicking the Play button in the toolbar. Review for pacing and tone shifts, make adjustments to pronunciation, and add pauses where needed. This helps reduce voice drift and improves overall flow in long-form voiceovers.
