What are openedai-speech and Hugging Face Transformers?

openedai-speech

openedai-speech is a self-hosted text-to-speech server that mimics the OpenAI audio speech API. It uses local models such as Piper and Coqui XTTS to generate audio without sending data to the cloud.

  • OpenAI speech API compatible
  • Piper and XTTS backends
  • Custom voice mapping
  • Drop-in replacement

Hugging Face Transformers

Transformers is a widely used library providing pretrained models for text, vision, audio, and multimodal tasks. It supports running and fine-tuning thousands of open models locally with PyTorch.

  • Thousands of pretrained models
  • Text, vision, audio support
  • Fine-tuning tools
  • Large ecosystem
