Docs for syllable_count assume phones_for_word returns string, not a list

[hugovk]

https://pronouncing.readthedocs.io/en/latest/pronouncing.html#pronouncing.syllable_count says:

>>> import pronouncing
>>> phones = pronouncing.phones_for_word("literally")
>>> pronouncing.syllable_count(phones)
4

Parameters: phones – a string containing space-separated CMUdict phones Returns: integer count of syllables in list of phones

However, phones_for_word returns a list, not a string (Python 2.7.12, pronouncing==0.1.3):

>>> import pronouncing

>>> phones = pronouncing.phones_for_word("literally")
>>> phones
[u'L IH1 T ER0 AH0 L IY0', u'L IH1 T R AH0 L IY0']

>>> pronouncing.syllable_count(phones)

The syllable_count examples in https://pronouncing.readthedocs.io/en/latest/tutorial.html#counting-syllables look fine.
