Direct AI Voices with Emotion & Sound Tags: Complete Cheatsheet (2026)
Master voice pacing, pauses, excitement, sighs, and whispers to make AI narration sound indistinguishable from human voice actors.
Flat, monotone AI narration is a solved problem — if you know how to direct the voice. The same way a director annotates an actor's script, you can annotate your text with emotion and sound tags that tell the AI exactly how to deliver each line.
This cheatsheet is the full catalog of directional tags that make AI narration sound alive.
1. The Full Emotion & Sound Tag Catalog
| Tag | Effect |
|---|---|
[say excitedly] | Raises pitch and velocity for triumphant moments |
[whisper in a hushed style] | Breathier texture for secrets and suspense |
[say solemnly] | Deeper pitch, slower cadence for gravity |
[speak cheerfully] | Brighter tone with a warm, smiling timbre |
[say sarcastically] | Ironic, drawn-out inflection |
[laugh] / [chuckle] | Inserts authentic laughter |
[sigh] | Renders a weary or relieved exhalation |
[gasp] | Sudden intake of breath for shock |
[pause:2s] | Exact timed silence for suspense |
2. Directing a Scene, Beat by Beat
Good voice direction follows the emotional arc of the text. A suspense scene starts hushed, builds to a discovery with excitement, and lands the reveal in a whisper. The tags map directly onto that arc:
- Set the mood — open with
[sigh]or[whisper]. - Hit the peak — shift to
[say excitedly]at the reveal. - Release the tension — close with
[laugh]or a timed[pause:2s].

Expressive Script with Natural Speech Directions
Supports natural directions e.g. [say excitedly], [whisper in a hushed style], and sounds [laugh], [sigh].
[sigh] I've been digging through this dusty attic for three straight days. The air is heavy with dust, and honestly, I was about ready to give up and call it a day. But then... I moved that heavy, old leather trunk in the corner. [say excitedly] Look at this! I actually found it! It's Grandpa's missing compass! [laugh] I can't believe it was just wedged between a stack of old newspapers and a broken lamp all this time. I thought for sure it had been lost at sea decades ago. Wait a second. The glass is cracked, but the needle is moving. It's not pointing north, though. It's dipping downward. [whisper in a hushed style] It's pointing straight down... toward the floorboards. There's something else hidden right underneath us.
