Zonos TTS

Today, I’m walking you through an amazing tool that I recently explored — Zonos TTS v1. This is a multi-language voice cloning and text-to-speech tool that allows you to create highly expressive and natural-sounding voiceovers in over 30 languages.

You can not only clone voices across different languages, but also adjust emotions and expressions to suit your text. In this article, I’ll guide you step-by-step on how to install, set up, and use Zonos TTS v1.

What is Zonos TTS v1?

Zonos TTS v1 is a text-to-speech and voice cloning tool that supports more than 30 global languages. It’s designed for those who want to create voiceovers in different languages and tones, making it great for content creators, developers, and multilingual projects.

System Requirements

Before jumping into the installation, make sure your system meets the minimum requirements:

    You can modify how the speech sounds: Happy, Sad, Angry, Excited, Calm. Select the emotion that best fits your text.
  5. Step 5: Generate Speech
    Click the Generate button. Depending on your GPU, it may take a minute.

If you have a low-end GPU, you may run into memory issues. In my case, I got a CUDA Out of Memory error.

Limitations and Suggestions

While Zonos TTS v1 is powerful, there are a few things to note:

  • No System Requirements: The GitHub page doesn’t mention exact GPU requirements.
  • Heavy on Resources: You may need expensive GPUs or cloud credits to run it.
  • Limited Public Access: The Hugging Face demo isn’t always available due to GPU caps.

Suggestion: The developers should consider adding minimum system requirements in their documentation.

Running into GPU Issues?

If you’re using a GPU with less than 6GB VRAM (like mine), here’s what you can do:

Option 1: Use the Hugging Face Demo

Go to the Zonos demo on Hugging Face.

  1. Upload your text.
  2. Choose the language and emotion.
  3. Generate audio online without running it locally.

This way, you still get to test how the voice cloning and emotion adjustment features work.

Option 2: Use a Cloud GPU

If you’re comfortable working in the cloud, you can:

  1. Rent a GPU-powered server from services like Google Colab Pro, RunPod, or Paperspace.
  2. Install Zonos following the same steps, adjusted for Linux.

Final Thoughts

Zonos TTS v1 is an impressive tool for creating voiceovers that sound natural and expressive, making it ideal for various applications in content creation and multilingual projects.
