# Using paraformer with grpc
We can send streaming audio data to server in real-time with grpc client every 10 ms e.g., and get transcribed text when stop speaking.
The audio data is in streaming, the asr inference process is in offline.


## Steps

Step 1) Generate protobuf file for grpc
```
python -m grpc_tools.protoc  --proto_path=./proto -I ./proto    --python_out=. --grpc_python_out=./ ./proto/paraformer.proto
```

Step 2) start grpc server
```
python grpc_main_server.py --port 10095
```

Step 3) start grpc client
```
python grpc_main_client_mic.py --host 127.0.0.1 --port 10095
```
