Stop using the default “Brian” robot voice for your Twitch donations. It’s boring, overused, and it doesn’t motivate your viewers to spend money.
Top streamers know a secret: text to speech for twitch is content.
If you set up a funny, realistic, or “meme” voice for your donations, viewers will spam that donate button just to hear it.
In this guide, I will show you how to upgrade your stream from the boring default TTS to high-quality ElevenLabs AI voices (like the viral “Adam” or Anime voices) in less than 10 minutes.
Listen to the difference:
Default TTS (Boring):
ElevenLabs Custom Voice (Engaging):
See the difference? The moment I set this voice up on my stream, viewers started spamming donations just to hear a ‘Sultry AI’ roast me. It is basically an Infinite Money Glitch.
Looking for the best text to speech for twitch? You are in the right place.
The Tech Stack: How It Works
ElevenLabs is the best text to speech for twitch generator, but it doesn’t connect directly to Twitch chat by itself. You need a “bridge” tool.
The easiest setup for 2025 is:
- Voice Engine: ElevenLabs (Generates the audio).
- The Bridge: Speaker.bot (A free tool that connects Twitch to ElevenLabs).
To get the best performance and lowest latency, we will use a dedicated desktop tool: Speaker.bot.
Step-by-Step Setup Guide
Here is exactly how to connect everything.
Step 1: Generate Your API Key (New 2025 Interface)
ElevenLabs recently updated their dashboard. First, you need an active account. If you don’t have one yet, click here to create a free account
Here is the new path to generate a key specifically for your stream:
- Click on the Developers tab in the bottom left corner.
- Go to API Keys and click the Create Key button.
You will see a popup with settings. Here is how to fill it out:
- Name: Type something simple like “Twitch Stream”.
- Permissions: Select “Access” and “Read” everywhere (otherwise, the bot won’t be able to load your voice list).
- SAFETY STEP: Set a Credit Limit!
- Do not skip this. Since you are granting full access, set a monthly limit (e.g., 10,000 characters).
- Why? This protects your wallet. Even if your key leaks on stream, hackers won’t be able to drain your bank account by generating hours of audio.
- Click “Create Key”. COPY THE KEY IMMEDIATELY and NEVER SHOW IT!
The Tool You Need: Speaker.bot
Since Twitch doesn’t support AI voices natively, you need a “bridge” application.
The best free tool for this is Speaker.bot. It’s a powerful software used by top streamers that allows you to connect external AI engines (like ElevenLabs) directly to your stream alerts and chat.
Step 2: Connect Speaker.bot to ElevenLabs
- Download and install Speaker.bot.
- Go to the “Settings” tab -> “Speech Engines”.
- Click “Add” and select ElevenLabs.
- Paste your API Key (the one you copied earlier).
- Now Speaker.bot can “see” all the voices from your ElevenLabs account (including Adam!).
Step 3: Create a Voice Alias
Now we need to create a “preset” for your donation voice.
- Stay in Settings and go to the “Voice Aliases” tab.
- Select your desired Voice from the list (e.g., Adam).
- Click “Test Speak” to make sure it works.
- Give it a Name (e.g., “Donate Reading Voice”).
- Click “Add”.
Step 4: Connect Voice to Donation Events
Finally, tell the bot to use this voice when someone donates.
- Go to the “Events” tab.
- In the Voice Alias section, select the new voice you just created (“Donate Reading Voice”).
- In the Pre-Event Setting, select “Donation”.
- In the Message field, type exactly:
%user% says: %message% - Click “Add”.
Step 5: Ensure OBS Hears It
You don’t need to add any special browser sources to OBS for the audio.
- Go to Settings -> Audio in Speaker.bot.
- Make sure the “Output Device” is set to your main headphones/speakers (the same device you hear your game on).
- In OBS, ensure your “Desktop Audio” is not muted.
Since Speaker.bot plays the voice through your default audio device, OBS will capture it automatically along with your game sound.
Best Text to Speech for Twitch Voices (My Recommendations)
I tested dozens of voices on stream. These three categories get the most engagement (and donations).
1. The “Gigachad” Narrator (Adam)
Perfect for “epic” donations or motivational messages. It commands respect.
- ElevenLabs Model: Adam (Premade). Adam is arguably the most famous AI voice right now. If you want to know why he went viral and hear more samples, check out my deep dive into the ElevenLabs Adam Voice here.
2. The “Anime/Waifu” Voice
If you have a gaming or anime-centric audience, using a high-pitched, energetic female voice prints money.
- ElevenLabs Model: Rachel or Glinda.
3. The “Troll” Voice
Clone a funny voice (or use an old man voice). Viewers love to use these voices to tell jokes. You can even clone a specific character voice for this. Read my ElevenLabs Voice Cloning Review to see how it works.
- Feature: Requires Voice Cloning (available in the Starter Plan).
The Cost: Is It Worth It?
Using ElevenLabs via API consumes characters (credits).
- Free Plan: You get 10,000 characters. That might last for 2-3 streams if your chat is slow.
- Starter Plan ($5/mo): You get 30,000 characters and Commercial Rights.
My Analysis: If this better voice setup encourages just one or two extra $3 donations per month, the subscription pays for itself immediately. It is an investment in your stream’s quality, not an expense.
Conclusion
Standard text to speech for twitch is dead. If you want to stand out on Twitch in 2025, you need a custom audio identity.
Setting up ElevenLabs with Speaker.bot takes 5 minutes, but the difference in viewer engagement is massive.
Pro Tip: You can use these same high-quality ElevenLabs voices to build a passive income stream on YouTube, without ever showing your face.
