1. A method of determining the likelihood of confusing a first word for a second word, comprising the steps of:

  • phonemically transcribing first and second orthographies of the first and second words into first and second phonemic transcriptions;

    calculating a Levinstein distance between the first and second phonemic transcriptions, wherein the Levinstein distance corresponds to edit operations required to transform the first phonemic transcription into the second phonemic transcription;

    obtaining a phonematic transformation weight for each edit operation of the Levinstein distance; and

    summing the obtained phonemic transformation weights to generate a value indicating the likelihood of confusion between the first and second words.
