Common Use Cases

What can you do with this library?

• look up the list of phones and syllables for canonical pronunciations of a word

  isletool.LexicalTool('ISLEdict.txt').lookup('cat')
  

• map an actual pronunciation to a dictionary pronunciation (can be used to automatically find speech errors)

  pronunciationtools.findClosestPronunciation(isleDict, 'cat', ['k', 'æ',])
  

• automatically syllabify a praat textgrid containing words and phones (e.g. force-aligned text) -- requires the praatIO library

  pysle.syllabifyTextgrid(isleDict, praatioTextgrid, "words", "phones")
  

• search for words based on pronunciation

  isletool.LexicalTool('ISLEdict.txt').search('dVV') # Any word containing a 'd' followed by two vowels
  

  e.g. Words that start with a sound, or have a sound word medially, or in stressed vowel position, etc.

  see /tests/dictionary_search.py

Version History

Pysle uses semantic versioning (Major.Minor.Patch)

Please view CHANGELOG.md for version history.

Requirements

• Python 3.7.* or above (or below, probably)

Click here to visit travis-ci and see the specific versions of python that pysle is currently tested under

• The praatIO library is required IF you want to use the textgrid functionality. It is not required for normal use.

ISLE Dictionary

pysle requires the ISLEdict pronunciation dictionary (copyright Mark Hasegawa-Johnson, licensed under the MIT open source license). This is bundled with psyle. However, you may want to use a subset of the pronunciations or you may want to add your own pronunciations.

In that case, please get the original file.

ISLEX github page

Direct link to the ISLEX file used in this project (ISLEdict.txt)

See examples/isletool_examples.py for an example of how to load a custom ISLEdict file.

Installation

Pysle is on pypi and can be installed or upgraded from the command-line shell with pip like so

python -m pip install pysle --upgrade

Otherwise, to manually install, after downloading the source from github, from a command-line shell, navigate to the directory containing setup.py and type

python setup.py install

If python is not in your path, you'll need to enter the full path e.g.

C:\Python36\python.exe setup.py install

Example usage

Here is a typical usage

from pysle import isletool
isleDict = isletool.LexicalTool('C:\islev2.dict')
print(isleDict.lookup('catatonic')[0]) # Get the first pronunciation
# >> (([['k', 'ˌæ'], ['ɾ', 'ə'], ['t', 'ˈɑ'], ['n', 'ɪ', 'k']], [2, 0], [1, 1]),)

and another

from pysle import isletool
from pysle import pronunciationtools

isleDict = isletool.LexicalTool('C:\islev2.dict')

searchWord = 'another'
phoneList = ['n', '@', 'th', 'r'] # Actually produced (ASCII or IPA ok here)

returnList = pronunciationtools.findBestSyllabification(isleDict, searchWord, phoneList)
syllableList = returnList[2]
print(syllableList)
# >> [["''"], ['n', '@'], ['th', 'r']]

Please see \examples for example usage
