How natural do the voices sound?

Modern TTS has crossed the line where most listeners can't reliably tell it apart from a human VO in a short clip. AdLit's voices include realistic breath sounds, micro-pauses and emphasis variation. They're tuned for ad-length content — under 90 seconds is where they shine.

Can I clone my own voice?

Voice cloning is a Pro-tier capability. Upload a 30-second sample of your voice (or a founder's, or a brand spokesperson's, with their consent), and AdLit produces a voice profile you can use across projects. Cloned voices follow the same speed/stability/style controls as library voices.

Which languages are supported?

35 languages covering most paid-social media markets: US/UK/AU/CA English, Spanish (ES, MX), Portuguese (BR, PT), French (FR, CA), German, Italian, Dutch, Polish, Swedish, Danish, Finnish, Czech, Slovak, Romanian, Bulgarian, Greek, Turkish, Arabic (SA, AE), Hindi, Tamil, Japanese, Korean, Mandarin, Indonesian, Filipino, Malay, Croatian, Ukrainian.

Can I control speed, pitch and emphasis?

Yes. Every render exposes speed (0–100), stability (how consistent the voice stays across a long script), similarity (how close to the reference voice it stays), and style exaggeration (deadpan vs. expressive). The same script can produce a meaningfully different read by tweaking these.

Type a script, pick a voice, hit render. AdLit's text-to-speech produces broadcast-quality narration in 35 languages — US/UK/AU English, Spanish (Spain + LatAm), Portuguese (Brazil + Portugal), Mandarin, Hindi, Arabic, Japanese, Korean, French, German, Italian and 20+ more. Each voice supports speed, stability, similarity and style controls, so the same script can sound conversational for a TikTok ad or measured for a B2B explainer.

The reality

Why this is hard today

Voice talent is a scheduling problem

Booking a VO artist for a single 30-second script means going through an agency, paying minimums, and waiting 48–72 hours. For ad iteration, that's the killer step.

Native-speaker matching at scale

Hiring a native Brazilian Portuguese voice, a Mexican Spanish voice, and a Castilian Spanish voice for the same campaign means three separate booking flows.

Accents create credibility cliffs

A US voice on a Spanish-language ad reads as foreign. Audiences notice within two seconds and CTR drops accordingly. Native accents matter even more than translation fidelity.

What you can ship

Built for these workflows

Localize one ad to 10 markets

Write the script in English, translate to each target market, switch the voice — all without re-renderering the visuals. Lip-sync handles the mouth shapes automatically.

Dub a product demo

Drop in a tutorial video, paste the new narration script, and ship the localized version the same day. No re-recording, no studio time.

Tune voice style per platform

Use a high-energy, fast-paced voice for TikTok hooks and the same script with a calmer, slower delivery for YouTube pre-rolls. Same words, two different feels.
