|
|
|
|
## Environment
|
|
|
|
We develop under:
|
|
* 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
|
|
|
|
> We make sure all things work fun under docker, and recommend using it to develop and deploy.

## Build
|
|
|
|
1. First to launch docker container.
|
|
|
|
```
|
|
docker run --privileged --net=host --ipc=host -it --rm -v $PWD:/workspace --name=dev registry.baidubce.com/paddlepaddle/paddle:2.2.2-gpu-cuda10.2-cudnn7 /bin/bash
|
|
```
|
|
|
|
* More `Paddle` docker images you can see [here](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/docker/linux-docker.html).
|
|
|
|
|
|
2. Build `speechx` and `examples`.
|
|
|
|
> Do not source venv.
|
|
|
|
```
|
|
pushd /path/to/speechx
|
|
./build.sh
|
|
```
|
|
|
|
3. Go to `examples` to have a fun.
|
|
|
|
More details please see `README.md` under `examples`.
|
|
|
|
|
|
## Valgrind (Optional)
|
|
|
|
> If using docker please check `--privileged` is set when `docker run`.
|
|
|
|
* Fatal error at startup: `a function redirection which is mandatory for this platform-tool combination cannot be set up`
|
|
```bash
|
|
apt-get install libc6-dbg
|
|
```
|
|
|
|
* Install
|
|
|
|
```bash
|
|
pushd tools
|
|
./setup_valgrind.sh
|
|
popd
|
|
```
|
|
|

## TODO

### Deepspeech2 with linear feature
|
|
* DecibelNormalizer: there is a small difference between the offline and online db norm. The computation of online db norm reads features chunk by chunk, which causes the feature size to be different different with offline db norm. In `normalizer.cc:73`, the `samples.size()` is different, which causes the different result.
