Build Status Build status Coverage Status License

SPTK.jl is a Julia wrapper for the Speech Signal Processing Toolkit (SPTK), which provides a lot of functionalities for speech signal processing such as linear prediction analysis, mel-cepstrum analysis, generalized cepstrum analysis and mel-generalized cepstrum analysis to name a few. See the original project page for more details.

NOTE: SPTK.jl is based on a modified version of SPTK (r9y9/SPTK).

Documentation

A reference manual of the SPTK can be found at http://sp-tk.sourceforge.net/.

Getting started

Functions that SPTK.jl provides are basically same as the SPTK, so if you are new to SPTK, please take a look at the original documentation first and then use SPTK.jl for your need. Also notice that there is no function exported, so you should explicitly import functions if you need.

e.g.

import SPTK: mcep, mgcep, freqt, mc2b

Supported Platforms

  • Linux
  • Mac OS X
  • Windows

Installation

Pkg.add("SPTK")

Info about upcoming removal of packages in the General registry

As described in https://discourse.julialang.org/t/ann-plans-for-removing-packages-that-do-not-yet-support-1-0-from-the-general-registry/ we are planning on removing packages that do not support 1.0 from the General registry. This package has been detected to not support 1.0 and is thus slated to be removed. The removal of packages from the registry will happen approximately a month after this issue is open.

To transition to the new Pkg system using Project.toml, see https://github.com/JuliaRegistries/Registrator.jl#transitioning-from-require-to-projecttoml.
To then tag a new version of the package, see https://github.com/JuliaRegistries/Registrator.jl#via-the-github-app.

If you believe this package has erroneously been detected as not supporting 1.0 or have any other questions, don't hesitate to discuss it here or in the thread linked at the top of this post.

Segmentation faults in mcep and mgcep

In runtests.jl

# TODO
function fail_tests()
    srand(98765)
    dummy_input = rand(1024)

    # segfaults
    mc = mcep(dummy_input, 40, 0.41)
    mgc = mgcep(dummy_input, 20, 0.41, 0.0)
end
