AI Voice: Narration Without a Microphone

Text-to-speech is the easiest place to start, because the payoff is immediate. You paste in a script, pick a voice, and get an audio file you can put under slides, screen recordings or stock footage.

The voice matters less than the script. Text written for reading sounds stiff when spoken. Write for the ear: short sentences, plain words, and contractions. Read the script out loud yourself first and change anything that trips you up. If you would not say it that way to a friend, the AI voice will not make it sound natural.

Small controls make a big difference. Most tools let you adjust pace, add pauses, and fix the pronunciation of names and unusual words. Spell awkward words the way they sound, and listen to the whole thing once before you publish.

Choose a stock voice from a service whose terms allow commercial use, and check that before you put it on anything you sell. Free plans often limit commercial use or add a credit requirement.

A consistent voice across your videos also works like a brand. Pick one that suits your material and stick with it, rather than swapping every week.

Takeaway: write for the ear, fix pronunciation, listen to the whole thing, and check that your plan allows commercial use.
