The following table lists the folders for different tasks.

|Recipe        | Speech Input | Speech Output | Comment|
|--------------|--------------|---------------|--------|
|Qwen-omni like| Continuous Embeddins| Cosyvoice1 50Hz Single-codebook Token | Text-driven; using Thinker LLM for text token, small Talker LLM for speech token |

### [Qwen-omni like Speech2speech Recipe](./qwen_omni)

[Qwen2.5-Omni](https://github.com/QwenLM/Qwen2.5-Omni) style model using [worstchan/Belle_1.4M-SLAM-Omni](https://huggingface.co/datasets/worstchan/Belle_1.4M-SLAM-Omni) dataset.

Command for training is:
```bash
pip install -r whisper_llm_zh/requirements.txt

pip install huggingface_hub['cli']
mkdir -p models/whisper models/qwen

# For aishell fine-tuned whisper model
huggingface-cli download --local-dir models/whisper    yuekai/icefall_asr_aishell_whisper exp_large_v2/whisper-large-v2-aishell1-epoch-10-avg-6.pt
# For multi-hans fine-tuned whisper model
# huggingface-cli download --local-dir models/whisper    yuekai/icefall_asr_multi-hans-zh_whisper v1.1/whisper-large-v2-multi-hans-zh-epoch-3-avg-10.pt

# First, we only train the projector and freeze other modules.
torchrun --nproc_per_node 8 ./whisper_llm_zh/train.py \
