MU-Talk: Grapheme-to-Phoneme Module

Robert Mannell

An ideal grapheme-to-phoneme (GTP) conversion system would be likely to have the following modules (illustrated in figure 1):

  1. GTP Dictionary
  2. Affix Processor
  3. Compound Word Processor (not currently implemented in MU-Talk)
  4. GTP rules
  5. Stress Rules

For an overview of the early development (mid-1980's) of the GTP modules of the SHLRC TTS system, read the following article. It provides a useful overview of many GTP features that have been retained in the MU-Talk TTS system:
