1. A system for developing word-pronunciation pairs based on a spell word input, comprising: a transcription generator receptive of the spelled word input for generating a phonetic transcription that corresponds to the spelled word input, said phonetic transcription being segmented into syllabic portions; a phonemic editor connected to said transcription generator for displaying and editing syllabic portions of said phonetic transcription; and a storage mechanism for updating a lexicon with the spelled word input and said phonetic transcription, thereby developing the desired word-pronunciation pair.
