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.

The method of claim 1, wherein the step of obtaining the phonemic transformation weights includes the substep of determining the phonemic transformation weight based on phonological features of phonemes used for edit operations.
