| 20110000360 | Apparatus and Method for Creating Singing Synthesizing Database, and Pitch Curve Generation Apparatus and Method - Waveform data representative of singing voices of a singing music piece are analyzed to generate melody component data representative of variation over time in fundamental frequency component presumed to represent a melody in the singing voices. Then, through machine learning that uses score data representative of a musical score of the singing music piece and the melody component data, a melody component model, representative of a variation component presumed to represent the melody among the variation over time in fundamental frequency component, is generated for each combination of notes. Parameters defining the melody component models and note identifiers indicative of the combinations of notes whose variation over time in fundamental frequency component are represented by the melody component models are stored into a pitch curve generating database in association with each other. | 01-06-2011 |
| 20110004476 | Apparatus and Method for Creating Singing Synthesizing Database, and Pitch Curve Generation Apparatus and Method - Variation over time in fundamental frequency in singing voices is separated into a melody-dependent component and a phoneme-dependent component, modeled for each of the components and stored into a singing synthesizing database. In execution of singing synthesis, a pitch curve indicative of variation over time in fundamental frequency of the melody is synthesized in accordance with an arrangement of notes represented by a singing synthesizing score and the melody-dependent component, and the pitch curve is corrected, for each of pitch curve sections corresponding to phonemes constituting lyrics, using a phoneme-dependent component model corresponding to the phoneme. Such arrangements can accurately model a singing expression, unique to a singing person and appearing in a melody singing style of the person, while taking into account phoneme-dependent pitch variation, and thereby permits synthesis of singing voices that sound more natural. | 01-06-2011 |
| 20110132179 | AUDIO PROCESSING APPARATUS AND METHOD - Phase setting section sets virtual phases in a frequency series of an audio signal. Unit wave extraction section extracts, from the frequency series, a unit wave of one cyclic period defined by the set virtual phases, for each of a plurality of time points. First generation section generates velocity information corresponding to a degree of compression/expansion, to a predetermined length, of the unit wave. Second generation section generates shape information indicative of a shape of a frequency spectrum of the unit wave having been adjusted. Variation component impartment section generates a variation component by use of the velocity information and shape information generated for the individual time points. | 06-09-2011 |
| 20120031257 | TONE SYNTHESIZING DATA GENERATION APPARATUS AND METHOD - For each one note or for each plurality of notes constituting a reference tone, a segment setting section segments a time series of actual pitches of the reference tone into one or more note segments. For each of the one or more note segments, a relativization section creates a time series of relative pitches that are relative values of individual ones of the actual pitches of the reference tone to a normal pitch of the note of the note segment. Information registration section stores, into a storage device, relative pitch information comprising the time series of relative pitches of each individual one of the note segments. The segment setting section may use musical score data, time-serially designating the notes of the reference tone, to set each of the note segments for each note designated by the musical score data, and may correct at least one of start and end points of each of the set note segments in response to user's operation. | 02-09-2012 |
| 20120103167 | APPARATUS AND METHOD FOR CREATING SINGING SYNTHESIZING DATABASE, AND PITCH CURVE GENERATION APPARATUS AND METHOD - Waveform data representative of singing voices of a singing music piece are analyzed to generate melody component data representative of variation over time in fundamental frequency component presumed to represent a melody in the singing voices. Then, through machine learning that uses score data representative of a musical score of the singing music piece and the melody component data, a melody component model, representative of a variation component presumed to represent the melody among the variation over time in fundamental frequency component, is generated for each combination of notes. Parameters defining the melody component models and note identifiers indicative of the combinations of notes whose variation over time in fundamental frequency component are represented by the melody component models are stored into a pitch curve generating database in association with each other. | 05-03-2012 |
| 20120310651 | Voice Synthesis Apparatus - A voice signal is synthesized using a plurality of phonetic piece data each indicating a phonetic piece containing at least two phoneme sections corresponding to different phonemes. In the apparatus, a phonetic piece adjustor forms a target section from first and second phonetic pieces so as to connect the first and second phonetic pieces to each other such that the target section includes a rear phoneme section of the first piece and a front phoneme section of the second piece, and expands the target section by a target time length to form an adjustment section such that a central part is expanded at an expansion rate higher than that of front and rear parts of the target section, to thereby create synthesized phonetic piece data having the target time length. A voice synthesizer creates a voice signal from the synthesized phonetic piece data. | 12-06-2012 |
