* More `Paddle` docker images you can see [here](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/docker/linux-docker.html).
* If you want only work under cpu, please download corresponded [image](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/docker/linux-docker.html), and using `docker` instead `nviida-docker`.
2. Build `speechx` and `examples`.
```
pushd /path/to/speechx
./build.sh
```
## Valgrind
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`.
1. Fatal error at startup: a function redirection which is mandatory for this platform-tool combination cannot be set up

## TODO
* DecibelNormalizer: there is a little bit difference between offline and online db norm. The computation of online db norm read feature chunk by chunk, which causes the feature size is different with offline db norm. In normalizer.cc:73, the samples.size() is different, which causes the difference of result.
