How to make text-to-speech sound more natural and human

The voice model matters, but pacing is what most people actually notice as "robotic" or "natural" — and pacing is fixable regardless of which voice you pick.

Auto-breathe: natural gaps without manual work

One click adds small silences at the places a real speaker would naturally pause: a short beat after clauses, a longer one after sentences, and the longest after paragraphs. It's careful about it — abbreviations like "Mr." or "approx." and decimal numbers don't get treated as sentence ends, so it won't chop up things that aren't actually pauses. Run it once on a wall of text and the rhythm improves immediately, no manual tagging required.

Exact pauses where the script needs them

For a pause that matters — a dramatic beat, time for a viewer to act, a breath before a call to action — Insert pause places an exact silence, from a fraction of a second to minutes, right where you click. Auto-breathe handles the general rhythm; manual pauses handle the moments that matter.

Speed: small adjustments go a long way

The Speed control ranges 0.5×–2.0×. Full-speed (1.0×) is rarely wrong, but a touch slower (0.9×–0.95×) often reads as more deliberate and human for narration, while a touch faster suits energetic or casual content. Small changes (±0.1) are usually enough — extreme speed in either direction is what starts to sound synthetic again.

Put it together, then listen

Draft is free and unlimited specifically so you can iterate on pacing without cost — auto-breathe, add a couple of manual pauses where the script needs emphasis, nudge the speed, and replay until it sounds like someone actually talking, not a machine reading text.
