How to make a text-to-speech video
A text-to-speech video is written text read aloud over visuals. The narration is the whole production, which means the script carries everything and the voice settings decide whether it lands.
Most bad synthetic narration is not the voice's fault. It is punctuation the reader follows literally, numerals it pronounces oddly, and sentences written for the eye rather than the ear.
You end with a finished vertical video, narrated and captioned.
Steps
Write the script to be heard, not read
Short sentences, one idea each, and no construction that depends on punctuation the ear cannot hear. A listener who loses the thread cannot go back three words, which is the constraint that makes written prose fail as narration even when it reads beautifully on a page.
Spell out anything a reader would guess at
Numerals, abbreviations, symbols and units are where synthetic narration most often embarrasses itself. Writing "nineteen ninety-nine" rather than "1999" removes the ambiguity, and doing it in the draft is faster than fixing it after you hear the result.
Use punctuation as timing
Full stops and commas become pauses, so they are pacing instructions rather than grammar. A sentence that runs long without a break will be read without one. Breaking a line where you want a beat is the most direct control you have over rhythm.
Generate, then listen once end to end
Read-throughs catch what proofreading cannot: a mispronounced name, a pause in the wrong place, a sentence that scans on paper and stumbles aloud. One listen is enough, and it is the step people skip most.
What you end up with
A vertical video where the narration reads naturally enough that the synthetic voice stops being the thing you notice — numbers spoken correctly, pauses where the meaning breaks, and captions matching the read word for word.
Watch sample videosWhen this isn't the right approach
If the video depends on performance — comic timing, genuine emotion, a distinctive personal delivery — record it yourself. Synthetic narration is excellent at being clear and unobtrusive and poor at being funny. It is also the wrong choice if your channel's appeal is you specifically, because the voice is most of what people attach to on a faceless channel.

Generate a videoFrequently asked
Does YouTube penalise text-to-speech narration?
No. Synthetic narration is widespread on monetised channels and is not disqualifying by itself. What matters is whether the script has a point of view, because repetitive content with nothing added is what the policies target regardless of who or what reads it.
Why does the voice mispronounce names?
Because it is guessing from spelling, and unusual names give it little to go on. Writing the name phonetically in the script fixes it more reliably than any setting. This is worth doing for anything that recurs, since a name mispronounced in every episode of a series is more noticeable than one error.
How long should a text-to-speech video be?
The same as any video of its format — the narration method does not change the length that works. Under sixty seconds for a Short, longer for anything where the subject needs room. What synthetic narration does change is how cheaply you can produce a long one, which is a temptation worth resisting.
Can I change the voice partway through a series?
You can, and it costs you recognition. On a faceless channel the voice is a large part of the identity, and viewers register a change immediately even when they cannot say what altered. Pick one and keep it unless you have a real reason to switch.
Why does synthetic narration sound flat even when the words are right?
Usually because the script has no variation in sentence length. A reader with nothing to work with delivers everything at one pace, and the ear reads that as monotony rather than as clarity. Mixing short sentences against longer ones gives the voice somewhere to breathe, and it is a script fix rather than a settings one — no amount of adjusting the voice compensates for prose written in a single rhythm.
