Model card
From the Hugging Face model README
CAM++ Chinese-English speaker embedding (sherpa-onnx)
This repository mirrors the complete public contents of iic/speech_campplus_sv_zh_en_16k-common_advanced at ModelScope revision v1.0.0 and adds a reproducibly exported ONNX model for sherpa-onnx.
The unmodified upstream files are stored in upstream/. The original model card is preserved as upstream/README.md.

The ONNX file is a format conversion of the upstream checkpoint. No training or fine-tuning was performed. Consumers must pin a repository commit and verify the ONNX SHA-256 instead of downloading from a floating branch.
Validation
The ONNX model passed onnx.checker.check_model. With the upstream example audio and sherpa-onnx's official test-onnx.py:
- same speaker: 0.6345000267028809
- different speaker: 0.06663094460964203
These two examples are conversion smoke tests, not a production authorization threshold. Applications must calibrate false-accept and false-reject behavior for their deployment conditions.
License and attribution
The upstream model card declares Apache License 2.0. A copy is included in LICENSE. This mirror preserves the upstream model card, attribution, examples, and configuration. The added ONNX conversion is clearly identified above.
