Title :
Letter-to-sound rules for Korean
Author :
Brew, C. ; Beckman, Moritz
Abstract :
We describe a Korean letter-to-sound (LTS) subsystem built within the Festival TTS framework. The subsystem has two major components. In the first step Korean orthography is deterministically mapped, without consideration of context, to a phonemic representation close to the ISO TR 11941:1996 transcription scheme. The second step is an implementation of the most important morphophonemic rules of Korean. This second component is somewhat more complex, and needs to respond to context, syllable structure, morphology and (ideally, but not implemented here) etymology. We outline the design principles of the TTS system of which this LTS module will be a part and describe the evaluation of the LTS rules against a large corpus.
