>&#13;     Chaves soundex tem a propriedade que palavras pronunciadas similarmente
     produzem a mesma chave soundex, e assim podem ser usadas em pesquisas
     em bancos de dados aonde você conhece a pronuncia mas não exatamente
     como se escreve. Esta função soundex retorna uma string de 4 caracteres,
     começando com uma letra.

     em "The Art Of Computer Programming, vol. 3: Sorting And
