Running Your Script Through the Voice Tool

The script you wrote for yourself is not the script you feed the voice tool. Two different documents. Treating them as one is the fastest way to end up with a robotic-sounding video.

Start with the obvious disaster. Do not paste your formatted script in. Whatever's sitting in that file, the word "hook" at the top, your timestamps, the bracketed notes about what's on screen, the little stage directions you left yourself, all of it gets read out loud in a calm professional voice. You'll hear a narrator say "hook," then "zero to fifteen seconds," then finally your first real line.

The fix starts earlier than you think. When you're generating the script, tell the model explicitly what you want out of it: plain raw text, ready for voiceover, no headings, no stage directions, no music cues, no formatting symbols of any kind. Every stray asterisk and hash that survives into that file is a symbol some voice engine will eventually try to pronounce.

Then keep two files. One is the working script with the headings and directions intact, the one you proofread against. The other is stripped bare, nothing but the words that get spoken, in order. The clean one is the only thing the voice tool ever sees. Raw text, natural paragraph breaks, and if you genuinely must leave a visual note in there, put it in obvious brackets so you can spot it and pull it before you generate. Keep the whole file under ten thousand characters while you're at it.

Now the part that actually decides whether the audio sounds human.

Text-to-speech wants different sentences than a person does. Write complete, flowing sentences of ten to thirty words. Where you'd naturally write three punchy short ones in a row about the same subject, join them into one sentence of twenty to thirty-five words instead. The engine needs runway. Give it a real clause and it produces something with shape and momentum. Give it four words and it produces four words and a dead stop.

Which means a lot of what makes written narration good will hurt you here. Fragments come out clipped. One and two-word sentences sound like glitches. Rhetorical questions get read flat, with the lift landing in the wrong place. Ellipses and em-dashes chop a line into pieces the voice can't reconnect. Strip almost all of them. You're writing for a reader that has no idea what you meant, only what you punctuated.

When you generate, go a paragraph at a time. A sentence at a time if it's an important one. Slower than pasting the lot and walking away, obviously, and it's the difference between a video where every line lands and a video with three duds you never caught because you were skimming a nine-minute render.

Judge each piece as it comes out. If a line sounds mechanical, run it again. Every regeneration comes back slightly different, so the exact same text can give you a much better read on the second attempt for no reason other than luck. Your first two regenerations don't cost credits either, so there's no excuse for keeping a bad one.

Then assemble the good takes in order and that's your track.

It's fiddly, it isn't creative, and you'll want to rush it. Don't. This is the layer the audience actually hears.
