Manually adjusting emotion
You can refine delivery without changing your script:- Insert or remove emotion tags around phrases to increase or reduce intensity.
- Add pacing with ellipses (
...) and commas to slow down or breathe between ideas. - Regenerate just the line/segment after small prompt tweaks for fast iteration.
Example: “We did it [excited]! … But [calm] there’s more work ahead.”
Voice selection: Male vs. Female
Choose a voice that matches the on-screen actor to maintain realism and lip-sync believability.- Match appearance: If the actor presents as female, choose a female voice; if male, choose a male voice.
- Context matters: For narration over b‑roll, you can choose any voice; for talking-head shots, match gender and tone to the actor.
- Brand consistency: Keep the same voice across versions unless testing variants.
