Donatty is a donation service with an alert widget where you can turn on TTS for messages. Many Russian-speaking streamers use it as their main way to receive support from viewers.
If you're choosing between Donatty TTS and TTS for your whole chat in character voices, here are the two compared, point by point. Donatty details come from its official help center as of November 2026.
In Donatty, TTS is part of the alert widget: a donation message is read along with the alert. Chat2Speech reads regular chat messages in character voices, with moderation and viewer voice subscriptions, half of which go to the streamer.
They don't get in each other's way: donations stay in Donatty, and chat speaks through Chat2Speech.
According to Donatty's help center, you turn TTS on in the alert widget settings, on the Properties tab, with a toggle. The Order row lets you choose when speech plays: before the alert sound, after it or during it. You can preview the result with the Play button before saving, and once saved, alerts on stream are read out loud.
That help article doesn't cover voice choice or whether donors can pick a voice themselves.
Alert TTS only fires on donations. On a smaller channel there aren't many, so the voice plays a couple of times per stream. Viewers who just chat stay as text in a corner, and new viewers see a quiet broadcast.
Whole-chat TTS in character voices gives everyone a reason to type and makes the stream feel alive even without donations.
A Donatty alert and Chat2Speech react to different events: the first reads a donation, the second reads regular chat messages. That makes them easy to run together: both go into OBS as separate sources, and you set each one's volume in the mixer. To keep voices from overlapping, set chat TTS a little quieter than the alert, or pick a Chat2Speech scheme where not every message speaks, such as the roulette for Channel Points or two rewards.
Setup takes a few minutes: sign in with Twitch, one link, a Browser source in OBS. No bot joins your chat and the service can't post there. Messages play about a second later in 250+ character, narrator and meme voices, filters skip links and bot commands, and mods run the queue with !tts skip, !tts clear and !tts mute @name right from chat.
The key differences between Donatty and Chat2Speech in one list.
A donation is a one-off: the viewer pays for one message, and the next one depends on their mood. A Chat2Speech voice subscription works differently: the viewer buys it on your channel for $9.99, $19.99, $49.99 and up, speaks in a premium voice with emotions for 30 days, is heard even after the daily limit and can change voice and name. Half of every purchase and every renewal goes to your balance, without Affiliate.
One doesn't replace the other: donations stay in Donatty, and subscriptions add recurring income from viewers who love to chat. Ten subscribers at $9.99 bring you about $49.90 for 30 days.
Yes. Chat2Speech is a separate OBS source and does not interfere with other services. Just watch the volume so two TTS sources do not speak at once.
Keep Donatty for donations if your viewers are used to it. If you want not just donations but your whole chat to speak in character voices, and give viewers one more way to support you, a voice subscription, add Chat2Speech.
You can try it free: 7 minutes of TTS a day, about 100 messages, no card. Plans for 70 minutes, 200 minutes or unlimited cost $5, $10 and $20 a month.
According to its help center: in the alert widget settings, on the Properties tab, switch the TTS toggle on and save.
