基于SpeechX 的 ASR 部署

简介

支持 U2/U2++/Deepspeech2 模型的 C++ 部署，其在工业实践中经常被用到。

更多 Speechx 信息可以参看文档。

使用

1. 环境

  • 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

更多信息可以参看文档。

2. 编译 SpeechX

更多信息可以参看文档。

3. 例子

u2++ 识别部署参看这里。

以下是在 speechx/speechx/examples/u2pp_ol/wenetspeech.

  • Source path.sh

    source path.sh

  • 下载模型，准备测试数据和cmvn文件

    run.sh --stage 0 --stop_stage 1

  • 解码

    # FP32
./local/recognizer.sh

# INT8
./local/recognizer_quant.sh
