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
