This toolkit compute posteriors probabilities of phonological classes from audio files for several groups of phonemes according to the mode and manner of articulation.

If you are not sure about what phonological classes are, have a look at thisPhonological classes tutorial

The list of the phonological classes available and the phonemes that are activated for each phonological class are observed in the following Table

Installation

From this repository:

git clone https://github.com/jcvasquezc/phonetcd phonetpython setup.py

Usage

Supported features:

  • Estimate probabilities of phonological classes for an audio file

Example use

Estimation of phonological classes

Estimate the phonological classes using the BGRU models for an audio file or for a folder that contains audio files inside:

pythonphon=Phonet([phonclass])get_phon_wav(self, audio_file, feat_file, plot_flag=True)
ParametersDescription
audio_filefile audio (.wav) sampled at 16 kHz
feat_filefile (.csv) to save the posteriors for the phonological classes
phonclasslist of phonological classes to be evaluatedThe list of phonological classes include:"consonantal", "back", "anterior", "open", "close", "nasal", "stop","continuant", "lateral", "flap", "trill", "voice", "strident","labial", "dental", "velar", "pause", "vocalic" or "all"
plot_flagTrue or False, whether you want plots of phonological classes or not
returnsIt crates the feat_file with the estimation of the phonological classes for each time-frame of the audio file.

Training

If you want to train Phonet in your own language, or specific phonological classes that are not defined here, please refer to the folder train and follow the instructions there.
