Description:
 def phonetic(s, method, concat=True, encoding='utf-8', decode_error='strict'):
 """Convert names or strings into phonetic codes. The implemented algorithms are `soundex <https://en.wikipedia.org/wiki/Soundex>`_, `nysiis <https://en.wikipedia.org/wiki/New_York_State_Identification_and_ Intelligence_System>`_, `metaphone <https://en.wikipedia.org/wiki/Metaphone>`_ or `match_rating <https://en.wikipedia.org/wiki/Match_rating_approach>`_. Parameters s : pandas.Series A pandas.Series with string values (often names) to encode. method: str The algorithm that is used to phonetically encode the values. The possible options are "soundex", "nysiis", "metaphone" or "match_rating". concat: bool, optional Remove whitespace before phonetic encoding. encoding: str, optional If bytes are given, this encoding is used to decode. Default is 'utf-8'. decode_error: {'strict', 'ignore', 'replace'}, optional Instruction on what to do if a byte Series is given that contains characters not of the given `encoding`. By default, it is 'strict', meaning that a UnicodeDecodeError will be raised. Other values are 'ignore' and 'replace'. Returns ------- pandas.Series A Series with phonetic encoded values. """
