For streamers
Twitch TTS Generator
Speech studio
32 voices · 18 languages
Generate alert audio, intros, and test donation messages with natural AI voices — a donation TTS simulator and test bench in one, with MP3 download for OBS or your alert provider. Free and sign-up optional.
How it works
Three steps, about a minute
- 1
Paste or write your text
Drop in a script, a paragraph, or a whole article. Longer text is split into parts automatically and joined back into one file.
- 2
Pick a voice and preview it
Every voice previews before you spend anything, including the paid ones. Filter by language, then hear two or three before committing.
- 3
Generate and download
Audio comes back in seconds as MP3 or WAV, with a commercial licence on every tier — including the free one.
Examples
Donation and alert scripts to test
Every clip below was generated here on the free tier — no account, no credits. Play one to hear the voice on that kind of writing, or load the script into the generator and make your own version of it.
Donation alert
A typical tip message, the way an alert reader would get it.
“BigDog97 donated five dollars: you said one more game an hour ago. I have been counting. We are at four.”
Resub message
A resub with a message — the second most common TTS trigger.
“Resubscribed for eight months: I was here for the lava jump, I was here for the lava jump apology stream, and I will be here for whatever this run becomes.”
Raid welcome
Pre-recorded raid welcome you can fire from a hotkey.
“Raiders, welcome in. Chat rules are pinned, the run so far is a disaster, and you have arrived at exactly the right time.”
Included
What you get
- Free without an account
- Thousands of characters a day as a guest, no sign-up and nothing to install. An account raises the limit; it is not a gate on the tool.
- Commercial use included
- Monetised videos, client work and ads are all fine on every tier. You own what you generate.
- MP3 and WAV export
- MP3 for editors and uploads, WAV where you need uncompressed audio. Speed is adjustable from 0.75× to 1.5× on engines that support it.
- Long text, one file
- Text past the per-request limit is split at sentence boundaries, generated in order, and stitched back into a single download.
- Voices across 18 languages
- Several languages are read by voices trained on that language rather than an English voice reading foreign words — the difference is audible immediately.
- Credits that never expire
- Premium and ultra voices are billed from one-time credit packs. No subscription and no monthly reset.
Donation TTS vs. generated audio
Most of what streamers call "Twitch TTS" is donation text-to-speech: a viewer tips with a message, and your alert service reads it out live. That runs inside StreamElements, Streamlabs, or a similar provider, and you configure the voice, minimum amount, and word filters there.
This tool does something different but complementary: it produces audio files. That covers everything the live reader cannot — custom alert sounds, intros and outros, BRB and starting-soon segments, and pre-recorded bits you drop into OBS.
What streamers generate here
Common uses on and around stream:
- Custom alert audio for follows, subs, raids, and tips
- Starting soon / BRB / stream ending voice segments
- Channel-point redemption sound effects with spoken lines
- Testing how donation copy sounds before enabling it live
- Narration for VOD recaps, highlight reels, and YouTube exports
Test a donation message before it hits your stream
The fastest way to break an alert setup is to hear it for the first time live. Use this page as the test bench: paste the kind of message your chat actually sends and listen for the failure points before you enable anything.
Four things to check on every test read:
- Usernames — TTS mangles handles like xX_Kn1ght_Xx; hear how bad it gets before a $2 tip does it on stream
- Length — most alert providers cut TTS at a fixed duration; time your test read against your alert timeout
- Spam patterns — paste an emote wall or a link once, so you know what your filters must catch
- Volume against game audio — export the MP3, drop it in OBS, and set the alert gain with the game running
The Twitch TTS voice: Brian, and what replaces him
When people say “the Twitch TTS voice” they almost always mean Brian — the flat British male from Amazon Polly that Streamlabs shipped as its default reader, which a decade of donation memes turned into the sound of the platform. StreamElements offers the same generation of cloud voices.
This site runs different engines, so there is no Brian clone here — and anything sold as one is scraping the same Polly API. What you get instead: Adam is the clear, confident male read that suits donation alerts; Miles is the relaxed version; Dan is the casual one for raid welcomes and bits. For a British accent the free tier currently has Emma and Poppy (both female). Every voice has a play button in the library, so audition with your own alert copy rather than a sample line.
Keeping TTS from becoming a problem
Live donation TTS gets abused — that is why most streamers set a minimum amount, enable word filters, and add a short delay before the message plays. Pre-generated audio sidesteps the issue entirely for anything you script yourself, which is why a lot of channels use live TTS only for tips and generated audio for everything else.
