摘要： Digital signal processing and machine learning techniques can be employed in a vocal capture and performance social network to computationally generate vocal pitch tracks from a collection of vocal performances captured against a common temporal baseline such as a backing track or an original performance by a popularizing artist. In this way, crowd-sourced pitch tracks may be generated and distributed for use in subsequent karaoke-style vocal audio captures or other applications. Large numbers of performances of a song can be used to generate a pitch track. Computationally determined pitch trackings from individual audio signal encodings of the crowd-sourced vocal performance set are aggregated and processed as an observation sequence of a trained Hidden Markov Model (HMM) or other statistical model to produce an output pitch track.

摘要： A method for following a musical score in real time. At least one sound emitted by a performer is recorded. At least one chromatic vector is estimated. The chromatic vector is compared with theoretical chromatic vectors of the musical score. A transition between the chromatic vector and a previous chromatic vector with theoretical transitions of the musical score is compared. A work position of the performer depending on a previous work position is estimated from the comparison of the chromatic vector and the comparison of the transition. The recording is carried out for a suitable period depending on the ratio between a period of the transition and a reference period.

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.

摘要： Methods and systems for performing audio synchronization with corresponding textual transcription and determining confidence values of the timing-synchronization are provided. Audio and a corresponding text (e.g., transcript) may be synchronized in a forward and reverse direction using speech recognition to output a time-annotated audio-lyrics synchronized data. Metrics can be computed to quantify and/or qualify a confidence of the synchronization. Based on the metrics, example embodiments describe methods for enhancing an automated synchronization process to possibly adapted Hidden Markov Models (HMMs) to the synchronized audio for use during the speech recognition. Other examples describe methods for selecting an appropriate HMM for use.
