Versions of Kaldi

Versioning scheme

During its lifetime, Kaldi has has three different versioning methods. Originally Kaldi was a subversion (svn)-based project, and was hosted on Sourceforge. Then Kaldi was moved to github, and for some time the only version-number available was the git hash of the commit.

In January 2017 we introduced a version number scheme. The first version of Kaldi was 5.0.0, in recognition of the fact that the project had already existed for quite a long time. The basic scheme is major/minor/patch, but the "patch" version number may also encompass features (usually back-compatible ones). The "patch number" automatically increases whenever a commit to Kaldi is merged on github.

We only intend to change the major or minor version number when making relatively larger changes, or non-back compatible changes.

We always plan to recommend that Kaldi users check out the latest version of 'master', since actively supporting multiple versions would increase our workload.

Versions (and changes)

This section lists the version numbers of Kaldi with the commit messages for each patch commit (by "patch commit" we mean a commit that does not increase the major or minor version number). Each time we add a new major/minor version number we will include a longer section explaining the changes involved.

Version 5.0

This is the first major/minor version number after introducing the versioning scheme. The latest revision of version 5.0 is saved as branch "5.0" on github.

Below are patches corresponding to minor version numbers 5.0.x.

Version 5.1

Some of the major changes introduced in version 5.1 are:

  • Kaldi now requires C++11 to compile, and we support only the latest version of OpenFst (1.6.0). (This simplifies Kaldi's code, and will later enable the threading code to be rewritten to use C++11's better and more portable mechanisms).
  • The way chunk size and feature context is handled in nnet3 is changed to allow variable chunk size and shorter context at utterance boundaries. See Context and chunk-size in the "nnet3" setup for more information.
  • A new decoding mechanism, Looped decoding, is introduced in nnet3; this allows faster and more-easily-online decoding for recurrent setups (but only unidirectionally-recurrent ones, like LSTMs but not BLSTMs).
  • Online decoding with nnet3 models is now rewritten; it's faster and it supports models like LSTMs.
  • The sequence-training scripts in nnet3 are refactored and are now simpler and use less disk space.
  • There are scripts for segmentation of long transcribed audio files.

The latest revision of version 5.1 is saved as branch "5.1" on github.

Version 5.2

Some of the changes introduced between 5.1 and 5.2 are:

  • Upgrades to nnet3 to support batch-norm and convolutional components; recipes for certain image tasks (like CIFAR).
  • nnet3 training script simplifications and refactoring.
  • Some of the recipes are upgraded to include dropout and the –proportional-shrink option (which approximates l2 regularization); this improves results.

Many changes were made in the commits listed below (i.e. in the minor versions 5.2.x), including:

The latest revision of version 5.2 is saved as branch "5.2" on github.

Below are patches corresponding to minor version numbers 5.1.x.

Version 5.3

Version 5.3 is the current master branch. Major changes that were made between the end of 5.2.x and the start of the 5.3 branch include:

  • Create a nnet3-based setup for RNN language models (i.e. recurrent and neural net based language models)
  • Some extentions to the core of the nnet3 framework to support constant values and scalar multiplication without dedicated compoennts.

Below are patches corresponding to minor version numbers 5.3.x.
