Customized Auto Speech Recognition
introduction
In some cases, we need to recognize the specific rare words with high accuracy. eg: address recognition in navigation apps. customized ASR can slove those issues.
this demo is customized for expense account, which need to recognize rare address.
-
this is address slot wfst, you can add the address which want to recognize.
-
after replace operation, G = fstreplace(G_with_slot, address_slot), we will get the customized graph.
Usage
1. Installation
install paddle:2.2.2 docker.
sudo docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.2
sudo docker run --privileged --net=host --ipc=host -it --rm -v $PWD:/paddle --name=paddle_demo_docker registry.baidubce.com/paddlepaddle/paddle:2.2.2 /bin/bash
2. demo
- run websocket_server.sh. This script will download resources and libs, and launch the service.
cd /paddle
bash websocket_server.sh
this script run in two steps:
-
download the resources.tar.gz, those direcotries will be found in resource directory.
model: acustic model
graph: the decoder graph (TLG.fst)
lib: some libs
bin: binary
data: audio and wav.scp -
websocket_server_main launch the service.
some params:
port: the service port
graph_path: the decoder graph path
model_path: acustic model path
please refer other params in those files:
PaddleSpeech/speechx/speechx/decoder/param.h
PaddleSpeech/speechx/examples/ds2_ol/websocket/websocket_server_main.cc
- In other terminal, run script websocket_client.sh, the client will send data and get the results.
bash websocket_client.sh
websocket_client_main will launch the client, the wav_scp is the wav set, port is the server service port.
- result: In the log of client, you will see the message below:
