From the model card

What fishaudio says about fish-agent

Read the model card

Fish Agent V0.1 3B is a groundbreaking Voice-to-Voice model capable of capturing and generating environmental audio information with unprecedented accuracy. What sets it apart is its semantic-token-free architecture, eliminating the need for traditional semantic encoders/decoders like Whisper and CosyVoice.

Additionally, it stands as a state-of-the-art text-to-speech (TTS) model, trained on an extensive dataset of 700,000 hours of multilingual audio content.

This model is a continue-pretrained version of Qwen-2.5-3B-Instruct for 200B voice & text tokens.

Supported Languages

The model supports the following languages with their respective training data sizes:

  • English (en): ~300,000 hours
  • Chinese (zh): ~300,000 hours
  • German (de): ~20,000 hours
  • Japanese (ja): ~20,000 hours
  • French (fr): ~20,000 hours
  • Spanish (es): ~20,000 hours
  • Korean (ko): ~20,000 hours
  • Arabic (ar): ~20,000 hours
