How to Set Up TTS on Twitch: Complete 2025 Guide

By StreamChat AI • January 31, 2026

Text-to-speech (TTS) has become one of the most popular features for Twitch streamers. Viewers love hearing their messages read aloud, and it creates memorable moments that keep people engaged. But setting up TTS can be confusing with all the different options available.

This guide walks you through everything you need to know about adding TTS to your Twitch stream in 2025.

What is TTS on Twitch?

TTS (text-to-speech) converts viewer messages into spoken audio that plays on your stream. When a viewer sends a message - usually through channel points, bits, or donations - a voice reads it aloud for everyone to hear.

It's popular because it:

Creates memorable, often hilarious moments
Gives viewers a bigger presence on stream
Works well for Just Chatting and variety content
Adds another layer of interaction beyond text chat

TTS Options for Twitch

There are several ways to add TTS to your stream:

1. StreamChat AI (AI-Powered TTS)

StreamChat AI's TTS uses advanced AI voices that sound natural rather than robotic. It includes built-in moderation to catch inappropriate messages before they're spoken, queue management, and integrates with Twitch channel points.

Pros: Natural-sounding voices, AI moderation, easy setup, channel point integration

Cons: Premium voices require paid plan

2. StreamElements TTS

StreamElements offers TTS through their integrated platform. It works with their alert system and loyalty points.

Pros: Integrated with StreamElements ecosystem, free

Cons: Basic voices, must use their full platform

3. Streamlabs TTS

Similar to StreamElements, Streamlabs includes TTS as part of their donation alerts and tip jar system.

Pros: Works with Streamlabs alerts, familiar interface

Cons: Primarily tied to donations/tips

4. Sound Alerts

Sound Alerts focuses specifically on audio alerts including TTS. It's a dedicated solution if you only need TTS functionality.

Pros: Dedicated to audio/TTS, large sound library

Cons: Basic TTS voices, no AI features

Setting Up TTS with StreamChat AI

Here's how to set up AI-powered TTS on your Twitch stream:

Step 1: Create Your Account

Step 2: Configure TTS Settings

In your dashboard, navigate to TTS settings:

Choose your preferred AI voice
Set volume and speed preferences
Configure message length limits
Enable moderation filters

Step 3: Create a Channel Point Reward

In your Twitch dashboard, create a channel point reward for TTS. Common setups:

500-1000 points for standard TTS
Higher costs for priority queue
Subscriber discounts using reward settings

Step 4: Add the Browser Source to OBS

Copy your TTS browser source URL from StreamChat AI and add it to OBS:

In OBS, click "+" under Sources
Select "Browser"
Paste your StreamChat AI TTS URL
Set dimensions (recommended: 800x200)
Enable "Control audio via OBS"

Step 5: Test and Go Live

Redeem a TTS reward yourself to test the setup. Verify the audio plays through OBS and the visual alert appears if enabled.

TTS Best Practices

Moderation is Essential

Without proper filtering, TTS can quickly become a problem. StreamChat AI's AI moderation catches inappropriate content before it's spoken, but you should also:

Set up word filters for obvious problems
Enable cooldowns to prevent spam
Have a skip button ready for emergencies
Consider sub-only TTS if issues persist

Balance Cost and Accessibility

TTS should feel special but not impossible to use. If the cost is too high, nobody uses it. Too low, and it gets spammy. Start with 500-1000 channel points and adjust based on usage.

Natural Voices Matter

Robotic TTS voices were funny in 2015. In 2025, viewers expect better quality. AI-powered voices like those in StreamChat AI sound more natural and don't grate on you after hours of streaming.

Troubleshooting Common Issues

No audio in OBS: Check that the browser source audio is routed correctly in OBS audio mixer
Messages not triggering: Verify the channel point reward is linked correctly in StreamChat AI
Audio too quiet/loud: Adjust in both StreamChat AI settings and OBS audio levels
TTS cutting off: Check message length limits in your settings
