What is Leelo?
Leelo is a voice cloning tool. A browser based text to speech and dubbing studio with 762 voices in 83 languages, per line direction for pace and emotion, sound effects, voice cloning and design, plus a REST API and MCP server on paid plans.
Leelo is a browser based voice studio that takes a written script and returns a finished audio mix. The library holds 762 voices spread over 83 languages and their regional accents, ranging from neutral newsreaders to character storytellers. Rather than a single text box that reads a paragraph aloud, Leelo splits pasted text into lines and assigns each speaker a voice, so a two person podcast or a five character scene can be drafted in one pass. The editing model is closer to a video timeline than a speech tool. Every line gets direction for pace, emotion and emphasis, and a pronunciation field lets a name like Leelo be fixed as LEE loh once for the whole project. Voices, music and sound effects sit on separate lanes with audible levels, and the export applies loudness targets suited to podcasts, audiobooks or broadcast. For work that does not fit cleanly into one language, a dubbing tool takes a video file or a link, translates it and re-voices each speaker while keeping their original voice, then hands the result back as an editable script per language. The surrounding toolkit covers the messy parts of production. Recordings can be transcribed with speaker attribution, cleaned of traffic and room hum, or re-performed by a different voice while keeping the original timing and delivery. Custom voices come in two flavours: design a voice from a written description and get three takes back, or clone a voice from about a minute of clean recording, with consent confirmation required on every attempt. A writing assistant generates scripts from a one line brief, rewrites prose for the ear, shortens lines, and translates up to 5,000 words at once. Independent creators are the obvious audience, but the pricing tiers and seat counts also point at small teams and agencies producing audio at volume. Anyone needing programmatic access gets a REST API, webhooks for long jobs and an MCP server for AI assistants. Buyers comparing against larger voice libraries should note that Leelo prices everything in one credit currency and shows the cost before any expensive job starts.
How do you use Leelo?
1Create an account and claim the free credits
Sign up with no card required. The account arrives with 1,000 free credits, roughly seven minutes of standard narration, which is enough to test the studio, dubbing and tooling before paying.
2Estimate the credit cost for your project
Check the use case page closest to your work to see a typical example cost, such as a ten minute voiceover at about 1,500 credits or a full phone menu at about 200.
3Pick voices from the library
Audition samples across languages and accents on the voices page, then note the ones that suit each speaker in your script.
4Build the mix in the Studio
Paste the script so it splits into lines, assign a voice per speaker, then set pace, emotion and emphasis line by line and fix any tricky pronunciations.
5Add sound effects and export
Place music and effects on their own lanes, balance the levels, and export one file with loudness set for your destination format.6Dub the finished piece into other languages
Upload the video or paste a link, choose target languages, review the per language script, and adjust any line back in the Studio.
Pros and cons
Pros
- Voice library is large and specific: 762 voices across 83 languages with regional accents, all playable as samples before signing upAI
- Line by line direction for pace, emotion, emphasis and pronunciation gives real control over how a script is deliveredAI
- Costs are shown before expensive jobs start, and failed jobs return their creditsAI
- Dubbing preserves each speaker's own voice and outputs an editable script per languageAI
- API, webhooks, MCP server and an embeddable article player are included from the Starter tier upwardAI
Cons
- Free plan is personal use only and its 1,000 credits do not renew, so commercial work requires paying from the startAI
- Monthly credit allowances reset and never roll over, which punishes projects with uneven month to month audio volumeAI
- Cloned and designed voices cost 5 credits per word against 1 for standard voices, a fivefold jump that adds up on long scriptsAI
- Clean up and the voice changer are priced at 1,300 credits a minute, so a single hour of source audio consumes a large share of a mid tier planAI
- Custom voices are limited per plan (one on Starter, three on Creator), so a cast of recurring characters needs a higher tier or extra spendingAI
