See how it works
Hear it before you sign up
Our free AI voice generator lets anyone turn a short script into a voice clip in seconds — no account, no credit card, no waiting. It's the fastest way to judge whether Sintra Studio's voices sound right for your video, post or show.
Real synthesis, not a mockup
Type two sentences, pick a male or female voice, and hear the actual TTS engine — the same Free voices you get in the studio.
Free MP3, no card required
Listen with no signup at all. Confirm an email address and the download is yours, free.
Human-verified, spam-free
A Cloudflare Turnstile check runs quietly in the background so the free tier stays usable and bot-free for everyone.
From your words to finished audio in 3 steps
No microphone, no recording booth, no audio editing software.
Paste your script or post
Paste the text you wrote, or upload a PDF, DOCX or TXT file. Tidy anything that only works on a page.
Choose a voice and generate
Pick a voice for each speaker and generate. Listen back, edit a line and regenerate just that line; unchanged lines are free.
Export your audio
Download an MP3 and add it to your video, your newsletter or blog post, or your podcast host.
What you can do today
A voice studio for people who write their own scripts. Everything listed here works now; we're in public beta and say so when something isn't ready.
Start from your own words
Paste a script, post or article, or upload a PDF, DOCX or TXT file.
Natural AI narration
Generate voice audio from your text and listen in the editor before you export.
A voice for every speaker
Write dialogue or interviews and give each speaker their own voice.
Free and Premium voices
24 Free voices in English and five other languages on every plan. Premium voices on Pro.
Fix one line, not the whole file
Edit a line and regenerate only that line. Unchanged lines cost no credits.
Export an MP3
Download loudness-normalized MP3 audio for your video editor, newsletter post or podcast host.
Why creators choose Sintra Studio
The terms matter as much as the voices.
Credits never expire
Credits are a one-time balance, not a monthly allowance. Publish weekly or once a quarter; unused credits stay yours.
Unchanged lines regenerate free
Fix one sentence and only that sentence costs credits. Lines you haven't changed come back at no cost.
Licensed Premium voices
Premium voices on the Pro plan come from a licensed voice library, so you know where the voice came from.
Your scripts stay yours
You keep ownership of what you write and upload. Sintra Studio processes it only to generate your audio.
An honest public beta
We say what works today and what doesn't yet, and early creators help decide what we build next.
Start free. Scale when you're ready.
1 credit = 1 character of generated speech, and regenerating unchanged lines is free. Free voices use Free-voice credits; Premium voices use Premium-voice credits. Credits never expire.

Built on trust and transparency
AI voice comes with responsibility. Here's what we do, and what we leave in your hands.
Disclose AI voice where platforms ask
YouTube, Apple Podcasts and Spotify each have rules for AI-generated voices. Our guides explain them so you can label your audio when you publish.
No voice cloning, no impersonation
Voice cloning isn't available yet. You choose from the voice library, so Sintra Studio can't be used to copy a real person's voice.
Your scripts stay yours
You keep ownership of the scripts you write and upload. We only process them to generate your audio.
Honest about the beta
We list what works today and say plainly what isn't ready yet, such as voice cloning and direct publishing.
