In this paper, considering the monosyllabic structure of the Chinese language, a whole class of syllable-based indexing features, including overlapping segments of syllables and Syllable pairs separated by a few syllables, is extensively investigated based on a Mandarin broadcast news database. The strong discriminating capabilities of such syllable-based features were verified by comparing with the word- or character-based features. Good approaches for better utilizing such capabilities, including fusion with the word- and character-level information and improved approaches to obtain better syllable-based features and query expressions, were extensively investigated. Very encouraging experimental results were obtained.Confidence measure; Retrieval of speech information; Syllable-based features; Term association matrix[SDGs]SDG10Speech information; Database systems; Information retrieval; Internet; Speech recognition; Speech analysisjournal article10.1109/TSA.2002.8025412-s2.0-0036649836
