Pronounced like 'p' + 'isle'.

An interface for the ILSEX (international speech lexicon) dictionary, 
along with some tools for working with comparing and aligning 
pronunciations (e.g. a list of phones someone said versus a standard or 
canonical dictionary pronunciation).

Common Use Cases
================

What can you do with this library?

- look up the list of phones and syllables for canonical pronunciations 
  of a word::
  
    pysle.isletool.LexicalTool.lookup('cat')

- map an actual pronunciation to a dictionary pronunciation (can be used 
  to automatically find speech errors)::
  
    pysle.pronunciationtools.findClosestPronunciation(isleDict, 'cat', ['k', 'æ',])

- automatically syllabify a praat textgrid containing words and phones 
  (e.g. force-aligned text) -- requires my 
  `praatIO <https://github.com/timmahrt/praatIO>`_ library::
  
    pysle.syllabifyTextgrid(isleDict, praatioTextgrid, "words", "phones")

- search for words based on pronunciation::

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

Requirements
================

- Before you use this library (before or after installing it) you will need
  to download the ILSEX dictionary.  It can be downloaded here under the
  section 'English' linked under the text 'English Pronlex'
  (with a file name of ISLEdict.txt):

  `ISLEX project page <http://isle.illinois.edu/sst/data/g2ps/>`_

  `Direct link to the ISLEX file used in this project
  <http://isle.illinois.edu/sst/data/g2ps/English/ISLEdict.txt>`_ (ISLEdict.txt)

- ``Python 2.7.*`` or above

- ``Python 3.3.*`` or above

- The `praatIO <https://github.com/timmahrt/praatIO>`_ library is required IF 
  you want to use the textgrid functionality.  It is not required 
  for normal use.


Installation
================

If you on Windows, you can use the installer found here (check that it is up to date though)
`Windows installer <http://www.timmahrt.com/python_installers>`_

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:\Python27\python.exe setup.py install

	
Example usage
================

Here is a typical common usage::

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

and another::

    from pysle import isle
    from psyle import pronunciationTools
    
    searchWord = 'another'
    anotherPhoneList = ['n', '@', 'th', 'r'] # Actually produced (ASCII or IPA ok here)

    returnList = pronunciationTools.findBestSyllabification(isleDict, 
                                                            searchWord, 
                                                            anotherPhoneList)
    print syllableList
    >> [["''"], ['n', '@'], ['th', 'r']]
    

Please see \\examples for example usage
