## Choose when

### Choose ChatTTS_colab if…

- Tags unique to ChatTTS_colab: chattts, colab-notebook, text-to-speech.
- When you want a simplified setup with minimal configuration needed in a browser-based environment using Google Colab.
- Leaner open-issue backlog (78).

### Choose VoxCPM if…

- Requirements: Python >= 3.10 (<3.13), PyTorch >= 2.5.0, CUDA >= 12.0.; For production deployment, Nano-vLLM is recommended for its high throughput and concurrent request support..
- Tags unique to VoxCPM: audio, deeplearning, minicpm, multilingual.
- Also covers Inference & Serving.
- When you need to generate high-quality, lifelike voice clones for multiple languages without the overhead of tokenizers.

## 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 VoxCPM

- If your project is constrained by hardware with less powerful GPUs than NVIDIA RTX 4090, as VoxCPM might not provide optimal real-time factor performance.
- When a simple text-to-speech solution suffices and does not require the advanced features like voice cloning or creative voice design that VoxCPM offers.
