Voice Changer for OBS Studio

Add real-time AI voice conversion to your OBS stream. Sound like anyone on stream with Real-Time and studio-quality audio. Free during beta.

AI Voice Conversion for OBS Streams

Echo is a free voice changer for OBS that uses AI voice changer technology to transform your voice during live streams. OBS Studio is the most popular streaming software in the world, and Echo integrates seamlessly as an audio input source. It uses RVC technology — a neural network that reconstructs your entire voice identity rather than applying cheap pitch-shifting effects. The result sounds like a genuinely different person, not an obvious voice filter. Audio processing runs locally on your machine in real-time, so your stream audio stays perfectly synced with your video. Whether you are streaming on Twitch, YouTube, or TikTok Live, this is the most natural-sounding OBS voice changer available.

Quick Start

How to use with OBS Studio

Step 1

Download & Install

Download Echo Live from the download page. The installer takes under 60 seconds. Available for Windows and macOS — no OBS plugin installation required.

Step 2

Add Audio Source in OBS

In OBS Studio, click the "+" button in the Sources panel. Select "Audio Input Capture" and name it (e.g., "Voice Changer"). In the Device dropdown, select "Echo". This captures the AI-processed audio as a dedicated source in your OBS scene.

Step 3

Go Live with a New Voice

In Echo, select a voice model and click Start. Back in OBS, mute your original microphone source and keep the Voice Changer source active. Hit "Start Streaming" — your audience hears the transformed voice in real-time.

Features

Why Streamers Choose Echo for OBS

Dedicated Audio Source

Echo appears as a standard audio input device in OBS. Add it as a separate source so you can control volume, apply OBS filters, and mix it independently from game audio and alerts.

Zero Audio-Video Desync

Audio processing completes in real-time — well below a single video frame. Your lip movements and voice stay perfectly synchronized on stream. No need for audio delay offsets in OBS.

Stream-Ready DSP

Built-in noise gate, compressor, and EQ process your audio before it reaches OBS. Get broadcast-quality voice without stacking multiple OBS audio filters. The noise gate alone eliminates keyboard and fan sounds.

Works with Streamlabs

Echo is not an OBS plugin — it is a system audio device. It works with OBS Studio, Streamlabs, Twitch Studio, and any other streaming software that accepts microphone input.

Voice Models

Voice Models for Streaming

Echo supports any .pth voice model from the RVC community. Streamers use voice models to create recurring characters, build unique stream personas, or switch voices for different content segments. Browse thousands of models on Weights.gg and Hugging Face, or train a custom model from your own voice recordings. Our voice model guide explains everything from finding models to importing and training them.

Technology

How AI Voice Changing Works in OBS

Traditional voice changers apply pitch shifting and audio effects to your microphone signal. These sound obviously processed — listeners immediately recognize a voice effect, which can be distracting during a stream. Echo uses RVC voice conversion, an AI voice changer technology powered by deep learning neural networks. Instead of manipulating your voice frequency, the AI extracts your speech content and reconstructs it using a trained voice model. The output sounds like a natural human voice, not an audio filter. For streamers, this distinction is critical. Your audience engages with your content, not your voice effect. A natural-sounding AI voice lets you maintain character consistency across an entire stream without listener fatigue. Combined with the built-in DSP processing, the audio quality matches or exceeds what most streamers achieve with dedicated hardware compressors and noise gates.

FAQ

OBS Studio Voice Changer FAQ

Is Echo free for OBS?

Yes, completely free during the beta period. No watermark on audio, no trial timer, no feature restrictions. Full access to all voice models and DSP effects at no cost.

Does Echo cause audio desync in OBS?

No. Audio processing runs in real-time, which is less than a single video frame at any framerate. Your voice and video stay perfectly synchronized without needing to add an audio delay offset in OBS.

Does it work with Streamlabs?

Yes. Echo is a system audio device, not an OBS-specific plugin. It works with OBS Studio, Streamlabs, Twitch Studio, XSplit, and any other software that accepts microphone input. The setup is the same — select "Echo" as your audio input device.

Can I use OBS audio filters with Echo?

Yes. Since Echo appears as a standard audio source in OBS, you can apply any OBS audio filter on top — gain, VST plugins, additional noise suppression, etc. However, the built-in DSP already handles noise gating, compression, and EQ, so additional filters are usually unnecessary.

Will my viewers know I am using a voice changer?

AI voice conversion (RVC) sounds like a natural human voice, not a processed effect. Most viewers cannot distinguish AI-converted speech from a real voice. The quality depends on the voice model — well-trained models produce very convincing results.
