Kaldi Speech Recognition Toolkit

================================



To build the toolkit: see `./INSTALL`.  These instructions are valid for UNIX

systems including various flavors of Linux; Darwin; and Cygwin (has not been

tested on more "exotic" varieties of UNIX).  For Windows installation

instructions (excluding Cygwin), see `windows/INSTALL`.



To run the example system builds, see `egs/README.txt`



If you encounter problems (and you probably will), please do not hesitate to

contact the developers (see below). In addition to specific questions, please

let us know if there are specific aspects of the project that you feel could be

improved, that you find confusing, etc., and which missing features you most

wish it had.

Development pattern for contributors

------------------------------------



1. [Create a personal fork](https://help.github.com/articles/fork-a-repo/)

   of the [main Kaldi repository](https://github.com/kaldi-asr/kaldi) in GitHub.

2. Make your changes in a named branch different from `master`, e.g. you create

   a branch `my-awesome-feature`.

3. [Generate a pull request](https://help.github.com/articles/creating-a-pull-request/)

   through the Web interface of GitHub.

4. As a general rule, please follow [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).

   There are a [few exceptions in Kaldi](http://kaldi-asr.org/doc/style.html).

   You can use the [Google's cpplint.py](https://raw.githubusercontent.com/google/styleguide/gh-pages/cpplint/cpplint.py)

   to verify that your code is free of basic mistakes.



Platform specific notes

-----------------------



### PowerPC 64bits little-endian (ppc64le)



- Kaldi is expected to work out of the box in RHEL >= 7 and Ubuntu >= 16.04 with

  OpenBLAS, ATLAS, or CUDA.

- CUDA drivers for ppc64le can be found at [https://developer.nvidia.com/cuda-downloads](https://developer.nvidia.com/cuda-downloads).

- An [IBM Redbook](https://www.redbooks.ibm.com/abstracts/redp5169.html) is

  available as a guide to install and configure CUDA.



### Android



- Kaldi supports cross compiling for Android using Android NDK, clang++ and

  OpenBLAS.

- See [this blog post](http://jcsilva.github.io/2017/03/18/compile-kaldi-android/)

  for details.



### Web Assembly



- Kaldi supports cross compiling for Web Assembly for in-browser execution

  using [emscripten](https://emscripten.org/) and CLAPACK.

- See [this post](https://gitlab.inria.fr/kaldi.web/kaldi-wasm/-/wikis/build_details.md)

  for a step-by-step description of the build process.
