How to Install Chatterbox TTS: A Step-by-Step Guide for Beginners

In the ever-evolving world of artificial intelligence, voice cloning and text-to-speech (TTS) technologies have made significant strides. One of the most exciting developments in this space is Chatterbox, an open-source voice-cloning model developed by Resemble AI that’s making waves for its performance, flexibility, and accessibility.

Why Chatterbox Stands Out

Chatterbox isn’t just another TTS engine—it’s a next-generation solution designed with developers, creators, and enterprises in mind. Here are some of its standout features:

  • MIT License: Fully open-source and free to use for both personal and commercial purposes.
  • Emotional Control: Add expressive tones to your audio output—perfect for storytelling, customer service, or entertainment.
  • Low Latency & Real-Time Synthesis: Ideal for live applications such as virtual assistants or interactive games.
  • Zero-Shot Voice Cloning: Clone any voice using just a short reference audio clip—no training required.
  • On-Premise Deployment: Run everything locally without relying on cloud services.
  • Secure & Watermarked Output: Ensures authenticity and protects against misuse.

Performance Comparison

In blind evaluations, Chatterbox consistently outperforms 11 Labs, one of the leading proprietary models in the field. Its ability to generate natural-sounding speech with accurate emotional inflection makes it a top contender in the AI voice generation arena.

How to Get Started with Chatterbox Locally

Here are the steps to install and run Chatterbox TTS on your local machine:

Prerequisites

  1. Python 3.8 or higher
  2. pip (Python package installer)
  3. PyTorch with GPU support (CUDA) recommended
  4. Optional: A virtual environment like venv or conda

🔧 Installation Steps

1. Create a virtual environment (optional but recommended)

python -m venv chatterbox-env
source chatterbox-env/bin/activate  # On Windows: chatterbox-env\Scripts\activate

2. Upgrade pip

pip install --upgrade pip

3. Install PyTorch (with CUDA for GPU)

Go to https://pytorch.org/get-started/locally/ for the correct install command.

For example:

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

If you’re using CPU only, replace the index URL with:

pip install torch torchvision torchaudio

4. Install Chatterbox

pip install chatterbox-tts

Basic Usage

import torchaudio as ta
from chatterbox.tts import ChatterboxTTS

model = ChatterboxTTS.from_pretrained(device="cuda")  # Use "cpu" if not using GPU

text = "Ezreal and Jinx teamed up with Ahri, Yasuo, and Teemo to take down the enemy's Nexus in an epic late-game pentakill."
wav = model.generate(text)
ta.save("test-1.wav", wav, model.sr)

Using a Custom Voice (Audio Prompt)

AUDIO_PROMPT_PATH = "YOUR_VOICE_SAMPLE.wav"
wav = model.generate(text, audio_prompt_path=AUDIO_PROMPT_PATH)
ta.save("test-2.wav", wav, model.sr)

Optional: Run Demo from example_tts.py

Download the repo or files from the official Chatterbox GitHub or Hugging Face space and run:

python example_tts.py

Generating Speech with Chatterbox

Using the Gradio interface, you can:

  1. Enter your text prompt
  2. Adjust tone and emotion (e.g., neutral, excited, sad)
  3. Modify speed and temperature settings for fine-tuning
  4. Upload a reference audio for zero-shot voice cloning

For example, try generating audio from a quirky recipe like:

“Now let’s make my mom’s favorite. So three Mars bars into the pan. Then we add the tuna and just stir for a bit.”

You can then tweak the parameters and hear how the tone changes with each adjustment.

Final Thoughts

Chatterbox represents a major leap forward in open-source voice generation. It combines high-quality output, real-time performance, and developer-friendly tools—all while remaining completely free for commercial use.

Whether you’re building a voice assistant, creating content, or developing a game, Chatterbox offers the tools and flexibility to bring your ideas to life.
