Chatterbox: FREE voice cloning BEATS Elevenlabs! (100% Local)
By Mervin Praison
Key Concepts
- Chatterbox: An open-source voice cloning AI model.
- Text-to-speech (TTS): Converting text into spoken audio.
- Voice cloning: Replicating a specific person's voice.
- Gradio: A Python library for creating user interfaces.
- Zero-shot voice cloning: Cloning a voice from a single audio sample without training.
- On-premise deployment: Hosting the model on your own server.
- Emotion control: Adjusting the emotional tone of the generated speech.
Installation and Setup
- Prerequisites: Python version 3.10 is recommended.
- Installation:
- Open your terminal or command prompt.
- Run the command:
pip install chatterbox-tts gradio
chatterbox-tts
is the main package for text-to-speech.gradio
is for the user interface.
- Running the User Interface:
- Save the provided code (available in the video description and GitHub repo) to a Python file (e.g.,
app.py
). - Navigate to the directory where you saved the file in your terminal.
- Run the command:
python app.py
- Open the URL provided in the terminal in your web browser. This will launch the Gradio user interface.
- Save the provided code (available in the video description and GitHub repo) to a Python file (e.g.,
Using the User Interface
- Text-to-Speech Generation:
- Enter the text you want to convert to speech in the text prompt box.
- Adjust the emotion controls (e.g., neutral, adding more emotions), speed, and temperature as desired.
- Click the "Generate" button.
- The generated audio will appear on the right-hand side.
- Click the play button to listen to the generated audio.
- Voice Cloning:
- Upload a reference audio file (e.g.,
.mp3
) containing the voice you want to clone. - Enter the text you want the cloned voice to speak in the text prompt box.
- Click the "Generate" button.
- The generated audio with the cloned voice will appear.
- Upload a reference audio file (e.g.,
Using the Code Directly
- Example Code: The video provides example code for Mac (available in the GitHub repo).
- Reference Audio: Ensure the reference audio file (e.g.,
audio.mp3
) is named correctly and located in the same directory as the code. - Running the Code:
- Open your terminal.
- Navigate to the directory containing the code and the audio file.
- Run the command:
python example_for_mac.py
(or the appropriate file name for your operating system).
- Output: The generated audio file will be saved in the same directory.
Key Arguments and Features
- Open-Source and Free: Chatterbox is MIT licensed, making it free to use for commercial purposes.
- Performance: It outperforms 11 Labs in blind evaluations.
- Emotion Control: Users can adjust the emotional tone of the generated speech.
- Low Latency: Designed for real-time voice synthesis.
- On-Premise Deployment: Can be hosted locally on your own server.
- Zero-Shot Voice Cloning: Clones voices from a single audio sample without requiring training.
- Developer-First: Built for developers, creators, and enterprises.
Examples and Demonstrations
- Text-to-Speech Example: The video demonstrates generating speech from the text "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."
- Voice Cloning Example: The video demonstrates cloning a voice from a reference audio file and using it to generate speech from the same text. The results are compared to the original audio.
Technical Details
- Python Version: 3.10 is recommended.
- Dependencies:
chatterbox-tts
andgradio
. - GitHub Repo: Contains example code for Mac, text-to-speech, voice cloning, and Gradio.
Synthesis/Conclusion
Chatterbox is presented as a compelling open-source alternative to commercial voice cloning services like 11 Labs. Its key advantages include its free and open-source nature, superior performance, emotion control, low latency, and on-premise deployment capabilities. The video provides a step-by-step guide to installing and using Chatterbox, both through the user interface and directly through code, showcasing its text-to-speech and voice cloning functionalities. The zero-shot voice cloning capability is particularly impressive, allowing users to clone voices from a single audio sample. The presenter encourages viewers to experiment with the tool and share their feedback in the comments.
