Qwen-omni like Speech2speech Recipe

Qwen2.5-Omni style model using worstchan/Belle_1.4M-SLAM-Omni dataset.

Command for training is:

torchrun --nproc_per_node $ngpu ./qwen_omni/train.py \
    --max-duration 50 \
    --enable-musan False \
    --exp-dir $exp_dir \
    --speech-encoder-path-or-name models/whisper/v1.1/whisper-large-v2-multi-hans-zh-epoch-3-avg-10.pt \
    --llm-path-or-name Qwen/Qwen2.5-0.5B-Instruct \
    --manifest-dir data/fbank \
    --deepspeed \
    --deepspeed_config ./qwen_omni/ds_config_zero1.json \
    --use-flash-attn True \
    --use-lora True --unfreeze-llm True --unfreeze-speech-projector True --enable-speech-output True

Command for decoding is:

python3 ./qwen_omni/decode.py \
    --max-duration 1 \
    --exp-dir $exp_dir \
    --speech-encoder-path-or-name models/whisper/v1.1/whisper-large-v2-multi-hans-zh-epoch-3-avg-10.pt  \
    --llm-path-or-name models/Qwen2.5-0.5B-Instruct \
    --epoch 999 --avg 1 \
    --manifest-dir data/fbank \
    --use-flash-attn True \
    --method e2e-epoch10_speech2speech \
    --enable-speech-output True \
    --token2wav-path models/CosyVoice-300M-SFT \
    --use-lora True
