RESEARCH ISSUES



  • Lexicon design and syllable definition

  • Acoustic model architecture

    -- Multiple paths
    -- HMM topologies
    -- Seeding techniques

  • Methods to integrate multiple levels of acoustic information

  • Statistical modeling of temporal information that exploits the syllable unit

  • Portability to new domains

    -- carefully defined syllabary
    -- choice of monosyllabic words
    -- triphone inventory
