# ASR Deployment by SpeechX
|
||||
|
||||
## Introduction
|
||||
|
||||
ASR deployment support U2/U2++/Deepspeech2 asr model using c++, which is good practice in industry deployment.
|
||||
|
||||
More info about SpeechX, please see [here](../../speechx/README.md).
|
||||
|
||||
## Usage
|
||||
### 1. Environment
|
||||
|
||||
* python - 3.7
|
||||
* docker - `registry.baidubce.com/paddlepaddle/paddle:2.2.2-gpu-cuda10.2-cudnn7`
|
||||
* os - Ubuntu 16.04.7 LTS
|
||||
* gcc/g++/gfortran - 8.2.0
|
||||
* cmake - 3.16.0
|
||||
|
||||
More info please see [here](../../speechx/README.md).
|
||||
|
||||
### 2. Compile SpeechX
|
||||
|
||||
Please see [here](../../speechx/README.md).
|
||||
|
||||
### 3. Usage
|
||||
|
||||
For u2++ asr deployment example, please to see [here](../../speechx/examples/u2pp_ol/wenetspeech/).
|
||||
|
||||
First go to `speechx/speechx/examples/u2pp_ol/wenetspeech` dir.
|
||||
|
||||
- Source path.sh
|
||||
```bash
|
||||
source path.sh
|
||||
```
|
||||
|
||||
- Download Model, Prepare test data and cmvn
|
||||
```bash
|
||||
run.sh --stage 0 --stop_stage 1
|
||||
```
|
||||
|
||||
- Decode with WAV
|
||||
|
||||
```bash
|
||||
# FP32
|
||||
./local/recognizer.sh
|
||||
|
||||
# INT8
|
||||
./local/recognizer_quant.sh
|
||||
```
|
||||
|
||||
Output:
|
||||
