Usage with sherpa-onnx

bash

./sherpa-onnx-offline \
  --tokens=tokens.txt \
  --paraformer=encoder-5-seconds.axmodel,predictor-5-seconds.axmodel,decoder-5-seconds.axmodel \
  --provider=axera \
  audio.wav

Known Limitations

INT8 quantization may cause accuracy loss; recognition output may be empty or partially missing
Fixed 5-second input length; longer audio requires external chunking
For higher accuracy, use U16 encoder + FP32 predictor + FP32 decoder variants
