    摘要： A system and method are disclosed for retrieving audio segments from a spoken document. The spoken document preferably is one having moderate word error rates such as telephone calls or teleconferences. The method comprises converting speech associated with a spoken document into a lattice representation and indexing the lattice representation of speech. These steps are performed typically off-line. Upon receiving a query from a user, the method further comprises searching the indexed lattice representation of speech and returning retrieved audio segments from the spoken document that match the user query.

    摘要： For each of a plurality of performance parts, a database (221) stores therein a plurality of part performance data. The part performance data for each of the parts includes a sound generation pattern and tone data corresponding to the sound generation pattern. A query pattern indicative of a sound generation pattern to be made an object of search is input by a user. A search is made through the database for part performance data including a sound generation pattern matching the query pattern. In response to a user's operation, one part performance data is identified from among searched-out results from the database, and the sound generation pattern of the identified part performance data is instructed as a new query pattern (Sa8b). Then, a further search is made through the database for part performance data including a sound generation pattern matching the new query pattern. In accordance with a user's operation, one part performance data is identified from among searched-out results, and the identified part performance data is edited. The thus-edited data can be registered into the database as new part performance data.

    摘要： The present invention generally relates to the field of content-based music information retrieval systems, in particular to a method and a query-by-humming (QbH) database system (100') for processing queries in the form of analog audio sequences which encompass recorded parts of sung, hummed or whistled tunes (102), recorded parts of a melody (300a) played on a musical instrument and/or a speaker's recorded voice (400) articulating at least one part of a song's lyrics to retrieve textual background information about a musical piece whose score is stored in an integrated database (103, 105) of said system after having analyzed and recognized said melody (300a).
    According to one embodiment of the present invention, said method is characterized by the steps of recording (S1) said analog audio sequences (102, 300a, 400), extracting (S4a) and analyzing (S4b) various acoustic-phonetic speech characteristics of the speaker's voice and pronunciation from spoken parts (400) of a recorded song's lyrics (102") and recognizing (S4c) syntax and semantics of said lyrics (102"). The method further comprises the steps of extracting (S2a), analyzing (S2b) and recognizing (S2c) musical key characteristics from the analog audio sequences (102, 300a, 400), which are given by the semitone numbers of the particular notes, the intervals and/or interval directions of the melody and the time values of the notes and pauses the rhythm of said melody is composed of, the key, beat, tempo, volume, agogics, dynamics, phrasing, articulation, timbre and instrumentation of said melody, the harmonies of accompaniment chords and/or electronic sound effects generated by said musical instrument. The invention is characterized by the step of calculating (S3a) a similarity measure indicating the similarity of melody and lyrics of the recorded audio sequence (102, 300a) compared to melody and lyrics of various music files stored in said database (103, 105) by performing a Viterbi search algorithm on a three-dimensional search space, said search space having a first dimension ( t ) for the time, a second dimension ( S ) for an appropriate coding of the acoustic-phonetic speech characteristics and a third dimension ( H ) for an appropriate coding of the musical key characteristics, and generating (S3b) a ranked list (107) of said music files.
