+# CPU Benchmark (ONNX)
+
+## Configuration
+### Data set:
+Aishell1 [test set](https://www.openslr.org/33/) , the total audio duration is 36108.919 seconds.
+
+### Tools
+#### Install [modelscope and funasr](https://github.com/alibaba-damo-academy/FunASR#installation)
+
+```shell
+pip3 install torch torchaudio
+pip install -U modelscope
+pip install -U funasr
+```
+
+#### Export [onnx model](https://github.com/alibaba-damo-academy/FunASR/tree/main/funasr/export)
+
+```shell
+python -m funasr.export.export_model --model-name damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch --export-dir ./export --type onnx --quantize True
+```
+
+#### Building for Linux/Unix
+
+Download onnxruntime
+```shell
+# download an appropriate onnxruntime from https://github.com/microsoft/onnxruntime/releases/tag/v1.14.0
+# here we get a copy of onnxruntime for linux 64
+wget https://github.com/microsoft/onnxruntime/releases/download/v1.14.0/onnxruntime-linux-x64-1.14.0.tgz
+tar -zxvf onnxruntime-linux-x64-1.14.0.tgz
+```
+
+Install openblas
+```shell
+sudo apt-get install libopenblas-dev #ubuntu
+# sudo yum -y install openblas-devel #centos
+```
+
+Build runtime
+```shell
+git clone https://github.com/alibaba-damo-academy/FunASR.git && cd funasr/runtime/onnxruntime
+mkdir build && cd build
+cmake  -DCMAKE_BUILD_TYPE=release .. -DONNXRUNTIME_DIR=/path/to/onnxruntime-linux-x64-1.14.0
+make
+```
+
+#### Recipe
+
+set the model, data path and output_dir
+
+```shell
+./bin/funasr-onnx-offline-rtf /path/to/model_dir /path/to/wav.scp quantize(true or false) thread_num
+```
+
+The structure of /path/to/models_dir
+```
+config.yaml, am.mvn, model.onnx(or model_quant.onnx)
+```
