9. A system for generating a lexicon for use with speech recognition, the system comprising: a processor; a first module configured to cause the processor to receive symbolic input as labeled speech data; a second module configured to cause the processor to overgenerate potential pronunciations based on the symbolic input, wherein the second module further causes the processor to: establish a set of conversion rules; and convert portions of the symbolic input into a number of possible lexical pronunciation variants based on the set of conversion rules; a third module configured to cause the processor to identify potential pronunciations in a speech recognition context to yield identified potential pronunciations; and a fourth module configured to cause the processor to store the identified potential pronunciations in a lexicon.
