• Feature: 80-dim fbank, mean normalization, speed perturb
• Training: lr [0.00005, 0.2], batch_size 256, 4 gpu(Tesla V100), additive angular margin, speaker embeddding=192
• Metrics: EER(%), MinDCF

• Train set: CNCeleb-dev + CNCeleb2, 2973 speakers
• Test set: CNCeleb-eval

Pretrained models are accessible on ModelScope.

• ERes2net-base: speech_eres2net_base_sv_zh-cn_cnceleb_16k
• ERes2Net-large: speech_eres2net_large_sv_zh-cn_cnceleb_16k
• 200k labeled speakers: speech_eres2net_sv_zh-cn_16k-common

Here is a simple example for directly extracting embeddings. It downloads the pretrained model from ModelScope and extracts embeddings.

# Install modelscope
pip install modelscope
# ERes2Net trained on CNCeleb
model_id=damo/speech_eres2net_base_sv_zh-cn_cnceleb_16k
# ERes2Net trained on 200k labeled speakers
model_id=damo/speech_eres2net_sv_zh-cn_16k-common
# Run inference
python speakerlab/bin/infer_sv.py --model_id $model_id --wavs $wav_path
