Create an AI voiceover

An AI voiceover can sound genuinely human, or it can sound like a GPS unit reading a ransom note. The gap between those two outcomes is almost entirely in the settings and the cleanup — not the script. Most people generate once, wince at the robotic pacing, and give up. The fix takes about ten minutes and two tools, both with free tiers, and the result is good enough for YouTube videos, podcasts intros, e-learning, or explainer clips.

The core insight: the raw generation is a first take, not a final take. Real voice actors do multiple takes and get edited. Your AI voice should too — generate it, then edit the pacing like you'd edit a text document.

What you'll walk away with

• A natural-sounding voiceover exported as a clean MP3
• The right voice-and-stability settings for your content's tone
• A cleanup pass that removes the tells that give AI voices away
• A repeatable process that takes minutes, not hours

Step by step, with the judgment that matters

1. Generate with ElevenLabs — the voice choice is 80% of it. Browse the voice library and match the voice to your content's actual tone before you touch anything else. An energetic voice reading a somber script is instantly wrong. The stability slider is the setting nobody explains: lower it (around 40%) for expressive, varied delivery; raise it for flat, consistent narration. Lower is usually better for anything meant to hold attention — the little variations are what read as "human."

2. Clean up in Descript. This is the step that separates a passable voiceover from a professional one. Import the audio; Descript transcribes it so you can edit the *sound* by editing the *text*. Delete filler, tighten awkward pauses, and cut any word the model mangled — just delete it from the transcript and the audio follows. Export when the pacing reads naturally.

A real run

For a 60-second product explainer, you pick a warm, mid-energy voice, drop stability to ~40%, and generate. The raw take has one weird half-second pause after "however" and rushes the final sentence. In Descript, you delete the pause in the transcript and add a beat before the call to action by nudging the gap. Ninety seconds of editing turns a decent take into one nobody questions. Total time under ten minutes.

Where it goes wrong

• It sounds robotic. Stability is too high, or the voice is wrong for the content. Drop the slider and try a different voice — this fixes it 90% of the time.
• A word comes out mangled. Common with names, acronyms, and unusual spellings. Either respell it phonetically in the script (e.g. "kling" → "kling ay-eye") or delete and re-record just that word in Descript.
• The pacing feels rushed. The model doesn't pause like a human. Add commas or line breaks in the script to force breaths, or insert the gaps manually in Descript.

The honest cost

$0 to about $5. ElevenLabs' free tier includes a monthly character limit that's plenty for short voiceovers; Descript's free tier covers the editing and a limited number of export minutes. You'd only pay if you're producing long-form audio regularly, or want voice cloning (ElevenLabs, paid) to use your own voice.
