pocketsphinx - 5.0.3: Major bugfix release Latest Release

Published by dhdaines 10 months ago

This release mainly fixes building for Python 3.12, but also fixes a serious bug in the NGramModel wrapper class along the way. Note that Python 3.6 and 3.7 are no longer supported.

pocketsphinx - 5.0.0: First official release in a decade or so

Published by dhdaines about 2 years ago

Finally, now that it is thoroughly obsolete, it is time to get PocketSphinx out of its eternal "prealpha" status. The version number is strangely large because "5prealpha" existed for such a long time that it became treated as a real release, and for some reason it did not have a conventional version number like, say, 1.0.0-alpha5.

The purpose of this release is to fix and document the public API, as well as to debug, stabilize, test, and fully document the current state of PocketSphinx. I do expect that there will be bug fixes and possibly some new APIs, but all 5.x releases are guaranteed to be backwards source and binary compatible.

Notably this release is not source-compatible in C with the previous versions. Your code will fail to compile. By contrast, in Python, old code should not fail at runtime, and if this isn't the case, please report it as an issue. Such is the way of the world with dynamic languages.

API documentation can be found at https://cmusphinx.github.io/doc/pocketsphinx/ and https://pocketsphinx.readthedocs.io/

Among other notable changes:

  • pocketsphinx_continuous is gone, replaced by plain old pocketsphinx, which is documented in the README file.
  • The configuration interface is now quite different. It is not a "command-line parser" anymore and the configuration parameters have lost their leading dashes.
  • All of the SphinxBase "utility" headers have also been made internal and their symbols will no longer be exported on Windows. Conversely, the JSGF and N-Gram language model API has been included in <pocketsphinx/model.h>.
  • The sphinx_fe and sphinx_cepview utilities have been moved to SphinxTrain.
  • The audio interface (<sphinxbase/ad.h>) has been removed.
  • The -remove_noise option is now controlled by the acoustic model as it needs to match the training.
  • The -remove_silence option has been removed as it is a Bad Idea and Considered Harmful for batch mode recognition. Please use the endpointer API as detailed in <pocketsphinx/endpointer.h> and examples/live.c or examples/live.py.
  • The -cmninit option is not controlled by the default acoustic model anymore. This may cause some problems for live recognition as the defaults may not match the feature extraction parameters.
  • The SWIG wrappers have been removed. Only Python 3 is directly supported as a dynamic language binding. Node.js may be supported in the near future. The C API is specifically designed to be easily supported through FFI, so you can do that.
  • Python support is much improved, fully documented, and builds a proper module directly from the (top level of the) source tree with pip or build.
  • Android support is gone but may come back (contributions welcome, I don't have time to support anything other than Linux on x86_64 and s390x)

pocketsphinx - 5.0.0rc5: Fifth (and final) release candidate

Published by dhdaines about 2 years ago

Basically everything I wanted to do is in this release, and more. If all goes well there will just be a final release in a couple days, then I can get on with the rest of my life.

pocketsphinx - 5.0.0rc4: Fourth Release Candidate

Published by dhdaines about 2 years ago

The purpose of this pre-release is to solidify and modernize the library API and ABI.

The configuration interface in particular is now quite different. It is not a "command-line parser" anymore and the configuration parameters have lost their leading dashes. So instead of this:

cmd_ln_set_str_r(ps_get_config(decoder), "-hmm", "/whatever/blah");

You now do this:

ps_config_set_str(ps_get_config(decoder), "hmm", "/whatever/blah");

As well, the parameter setting functions will coerce the value you give them to whatever the underlying parameter is instead of printing an error and failing (or worse, crashing the program, like they used to do in the bad old days). So it is okay to do this for instance:

ps_config_set_str(ps_get_config(decoder), "samprate", "16000");

As well, configurations can be saved and loaded as JSON (or a sort of pseudo-YAML as well). This is the recommended way to create configurations from scratch as well at the moment though I may bring back something like cmd_ln_init() as it was quite convenient.

All of the SphinxBase "utility" headers have also been made internal and their symbols will no longer be exported on Windows. Conversely, the JSGF and N-Gram language model API has been included in <pocketsphinx.h>.

The pocketsphinx command-line program now accepts input files on the command-line which can be raw, WAV, or NIST Sphere format.

pocketsphinx - 5.0.0rc3: Third Release Candidate

Published by dhdaines about 2 years ago

The main point of this pre-release is to reintegrate and reclaim the pocketsphinx-python module into the main source tree. The API is not precisely the same because some bits are no longer relevant, but it should support code written for that module. Some more rigorous testing will be done before the final release.

The secondary point is to begin improving the documentation, but it's not quite there yet.

pocketsphinx - 5.0.0rc2: Second Release Candidate

Published by dhdaines about 2 years ago

  • Fix system-wide installation (pkg-config, models, get_default_args())
  • Make Python module "batteries-included" unless USE_INSTALLED_POCKETSPHINX option is set (see Dockerfile for example)
  • Add a Dockerfile, but note that audio Does Not Work, Ever inside a Docker container, so don't even try and please don't file any bugs
  • Start writing real documentation
  • Reinstate something like pocketsphinx_continuous but just called pocketsphinx

pocketsphinx - 5.0.0rc1: First Release Candidate

Published by dhdaines about 2 years ago

Why This pre-Release?

PLEASE DO NOT BUILD DISTRIBUTION PACKAGES FROM THIS PRERELEASE. The API is nearly guaranteed to change before the true release. I do not want to end up with a shared library named libpocketsphinx.so.362.3.4. THIS IS A PRERELEASE AND NOT A REAL RELEASE!!! (sorry for the shouting but I want to make it clear that although PocketSphinx was a "prealpha" for 10 years, this is not going to be the way things work anymore)

The purpose of the 5.0.0 release will be to debug, stabilize, test, and fully document the current state of PocketSphinx. As part of this, some APIs have been removed, others are deprecated, and a few have changed and may still change. Notably:

  • SphinxBase is integrated into PocketSphinx now. The header files remain the same.
  • The sphinx_fe and sphinx_cepview utilities have been moved to SphinxTrain.
  • The audio interface (<sphinxbase/ad.h>) has been removed.
  • The -remove_noise option is now controlled by the acoustic model as it needs to match the training.
  • The -remove_silence option has been removed as it is a Bad Idea and Considered Harmful for batch mode recognition. Please use the endpointer API as detailed in <pocketsphinx/endpointer.h> and examples/live.c or examples/live.py.
  • The -cmninit option is not controlled by the default acoustic model anymore. This may cause some problems for live recognition as the defaults may not match the feature extraction parameters.
  • The SWIG wrappers have been removed. Only Python 3 is directly supported as a dynamic language binding. Node.js may be supported in the near future. The C API is specifically designed to be easily supported through FFI, so you can do that.
  • Python support is much improved, fully documented, and builds a proper module directly from the (top level of the) source tree with pip or build.
  • The GStreamer module is gone but it will come back, sorry.
  • Android support is gone but may come back (contributions welcome, I don't have time to support anything other than Linux on x86_64 and s390x)
