# ChatTTS_colab vs WaveRNN

*GraphCanon updated Jul 29, 2026*

## Verdict

Pick ChatTTS_colab if chatTTS_colab offers one-click deployment for ChatTTS text-to-speech applications on Colab and supports voice style selection, long audio generation, and streaming output; pick WaveRNN if waveRNN is a Python-based neural vocoder that can generate high-quality speech from text when used with TTS models like Tacotron.

[ChatTTS_colab](https://github.com/6drf21e/ChatTTS_colab) reports 2.6k GitHub stars, 324 forks, and 78 open issues, last pushed May 31, 2026. [WaveRNN](https://fatchord.github.io/model_outputs/) has 2.2k stars, 687 forks, and 108 open issues, last pushed Jul 2, 2022. Figures are from public GitHub metadata via [ChatTTS_colab's repository](https://github.com/6drf21e/ChatTTS_colab) and [WaveRNN's repository](https://github.com/fatchord/WaveRNN).

## Shared compatibility

- **Python**: [ChatTTS_colab](/tools/6drf21e-chattts-colab.md) - Python runtime; [WaveRNN](/tools/fatchord-wavernn.md) - Python runtime

## Decision facts: ChatTTS_colab

- **Adopt for:** ChatTTS_colab offers one-click deployment for ChatTTS text-to-speech applications on Colab and supports voice style selection, long audio generation, and streaming output.

## Decision facts: WaveRNN

- **Requirements:** Python version must be equal to or higher than 3.6; Pytorch 1 with CUDA support is a prerequisite
- **Adopt for:** WaveRNN is a Python-based neural vocoder that can generate high-quality speech from text when used with TTS models like Tacotron.

## Choose when

### Choose ChatTTS_colab if…

- Tags unique to ChatTTS_colab: chattts, colab-notebook.
- When you want a simplified setup with minimal configuration needed in a browser-based environment using Google Colab.
- More GitHub stars (2.6k vs 2.2k) - visibility, not fit.

### Choose WaveRNN if…

- Requirements: Python version must be equal to or higher than 3.6; Pytorch 1 with CUDA support is a prerequisite.
- Tags unique to WaveRNN: neural-vocoder, pytorch, speech-synthesis, tacotron.
- When you require a compact and efficient method to produce natural-sounding speech synthesis, specifically with the need for high fidelity in audio quality.

## When NOT to use ChatTTS_colab

- If your project needs do not include the ability to generate audio on-the-fly or manage multiple character readings.
- When you want to avoid Colab's resource limitations that could affect performance for heavy text-to-speech tasks.
- In scenarios where offline package support is not necessary, as this might introduce unnecessary complexities.

## When NOT to use WaveRNN

- Avoid using when you need extensive customization of the vocoder parameters, since it is optimized for specific configurations and might not offer the level of tweakability other frameworks provide.
- Not recommended if your setup does not support CUDA, as WaveRNN requires PyTorch with CUDA for execution.
