WS97 SYLLABLE SYSTEM MILESTONES



  • Hybrid syllable-based system (WER: 49.0%) surpassed a comparable context-dependent phone system (WER: 49.8%)

  • A mixture of acoustic units and topologies is beneficial

    -- monosyllabic word modeling
    -- syllables + context-dependent phones
    -- finite duration syllables

  • Clustering of syllable models based on spectral features helps improve performance
