#!python

import fuzzy
fdm = fuzzy.DMetaphone()
fdm10 = fuzzy.DMetaphone(10)

# note that this also trounces the 's' phoneme of 'decent'
>>> fdm('decent')
['TKNT', None]

>>> fdm('decentralization')
['TKNT', None]

>>> fdm10('decentralization')
['TKNT', None]


# ..for comparison:
import metaphone
mdm = metaphone.dm

>>> mdm('decent')
('TSNT', '')

>>> mdm('decentralization')
('TSNTRLSXN', '')

Expected behavior:

• produce phonemes for the whole word, or for the word up to the length specified.

Yes, this has bitten me too...

Here's an example I ran across:

for carbohydrate fuzzy gives KRPH as opposed to KRPHTRT for the original library.

It would be great to get this fixed.

Thanks!
