How to Add AI Voiceover to Videos (2026 Guide) | Viralance
Choose your settings and review the credit cost before generating.
Create your first videoA voiceover is the difference between a clip people scroll past and a story they finish. If you run faceless TikToks, Reels, or Shorts, you need narration on demand — without a microphone, a quiet room, or a second take. This guide walks through adding text-to-speech narration in Viralance: the exact workflow, the voices, what it costs, and how to make the audio sound like a person rather than a machine.
What is AI voiceover, and how does text-to-speech work?
AI voiceover (text-to-speech, or TTS) converts written text into spoken audio using a neural voice model. You write a script, pick a voice, and the model generates speech — including intonation, pacing, and pauses. Viralance's Voiceover tool runs on ElevenLabs' Eleven v3 model (via fal), which ElevenLabs describes as its most expressive speech model.
The output is a standard MP3 file. Because it is a plain audio file, you can drop it onto AI-generated clips, stock footage, screen recordings, or a product demo in any editor you already use. Viralance does not merge the audio into a video for you on this screen — that happens in your editor.

How do I add an AI voiceover in Viralance?
The whole process lives on one screen:
- Go to Dashboard → Voiceover. You will see a Script field on the left and a Choose a voice list on the right.
- Paste your script. The field accepts up to 5,000 characters per generation, with a live counter (e.g. 1,240/5000). ElevenLabs estimates 5,000 characters at roughly five minutes of speech; most short-form scripts are a few hundred characters.
- Choose a voice. Tapping a voice selects it and plays a short pre-recorded sample of that voice. The sample is free, but it is a fixed demo line — it does not read your script.
- Check the cost. The header shows "This costs N credits" for the current script length.
- Click Generate with [voice]. The audio renders and appears in a built-in player under "Your voiceover".
- Download the MP3 and add it to your edit.
Your ten most recent renders appear under Recent voiceovers, so you can play and re-download a past narration without paying again.

What voices and languages are available?
Viralance offers 21 Eleven v3 voices: Aria, Roger, Sarah, Laura, Charlie, George, Callum, River, Liam, Charlotte, Alice, Matilda, Will, Jessica, Eric, Chris, Brian, Daniel, Lily, Bill, and Rachel. Each has a short descriptor in the picker — for example Brian is "Male · deep narrator", Sarah "Female · soft & calm", Daniel "Male · authoritative (British)" and River "Neutral · calm".
There is no language selector in the Voiceover tool. ElevenLabs lists 70+ supported languages for Eleven v3, and in practice you write the script in the target language and the voice reads it. Accent and pronunciation quality vary by voice and language, so generate a short test line before committing a full script in a language you can't check yourself.

How much does an AI voiceover cost?
Viralance uses one-time credit packs with no subscription, and credits never expire. Voiceover cost is tied to script length:
- 1 credit per 500 characters, rounded up
- Minimum 2 credits per generation
| Script length | Credits | At Mini ($0.30/credit) | At Business (~$0.18/credit) |
|---|---|---|---|
| Up to 1,000 characters (a typical hook or 30s script) | 2 | $0.60 | $0.36 |
| 2,500 characters | 5 | $1.50 | $0.91 |
| 5,000 characters (maximum) | 10 | $3.00 | $1.81 |
Voice samples are free. If a generation fails, the credits are refunded automatically. New accounts get 4 free credits after email verification — enough for two short voiceovers.

How do I make AI narration sound natural?
Most of the realism comes from the script, not the model. A few habits make an audible difference:
- Write for the ear. Short sentences and contractions ("you'll," "it's") read more like speech. Say the line out loud before you paste it.
- Use punctuation as direction. Commas make small pauses; periods and line breaks make bigger ones; an ellipsis (…) adds a beat before a payoff.
- Match voice to tone. A softer voice like Sarah or Charlotte suits narrative content; a firmer one like Brian or Daniel fits explainers and ads.
- Front-load the hook. Your first line decides whether anyone stays — keep it short.
- Fix tricky names phonetically. If a brand or acronym sounds off, respell it the way it should sound and regenerate a short test first (a short test costs the 2-credit minimum).

How do I use AI voiceover for faceless content?
Faceless formats — motivational, history, finance, story-time, product reviews — are carried entirely by narration. A repeatable loop:
- Draft the script and keep the opening line under ten words.
- Generate the voiceover with one consistent voice so your channel has a recognizable sound.
- Generate matching visuals with Viralance's video models, or use your own B-roll.
- Sync audio to picture in your editor — cut on the rhythm of the narration.
- Add captions, since a lot of short-form viewing happens muted. Viralance's Auto Subtitles tool (Dashboard → Edit Video → Subtitles, 3 credits) burns captions into a finished video.
- Download and upload the finished video yourself to TikTok, Reels, or Shorts. Viralance does not post to social platforms for you.

When Viralance's voiceover is not the right tool
- You need a custom or cloned voice — the tool offers only the 21 preset voices.
- You need fine control over stability, emotion tags or per-language settings — the Voiceover screen exposes script and voice only.
- You need long-form narration beyond 5,000 characters — split it into parts and join them in your editor, or use a dedicated TTS product.
For short-form narration on the same credit balance you use for video and images, it is a quick option. Head to Dashboard → Voiceover, paste a script, and tap a voice to hear it.
