spanish_metaphone

)

This is a Spanish version of the standard double metaphone tokenizer.

Metaphone allows matching of strings phonetically, but is very language- dependent. The standard metaphone algorithm is for English, and misses a few rules for Spanish. This is a version that takes Spanish pronunciation into account when generating tokens.

Returns:

a metaphone token for the given Spanish string.

Parameters:

string

The string to tokenize.
