To do.

<B: Operation>
Next, the operation of this embodiment will be described below. First, the CPU 11 of the authoring apparatus 1 reads voice data from the storage unit 14, performs voice analysis processing on the read voice data, calculates a pitch, power (volume), and spectrum corresponding to time from the voice data, Pitch data, power data, and spectrum data indicating the calculated pitch, power, and spectrum are generated. Subsequently, the CPU 11 analyzes the audio data and the accompaniment data in a predetermined frame unit, and detects a temporal correspondence between the audio data and the accompaniment data. Then, the CPU 11 analyzes a pattern of temporal change in pitch, power, and spectrum calculated from the audio data, determines whether or not the analysis result corresponds to a predetermined pattern, and corresponds to the case. Specifies the section corresponding to the pattern as a section in which a specific singing technique is used. Then, the CPU 11 associates the time information of the specified section with the identification information indicating the singing technique, and outputs it by storing it in the singing technique data storage area 14c of the storage unit 14.

  Here, the identification process of the area where each singing technique is used is demonstrated below. In the present embodiment, the CPU 11 specifies (detects) a section in which each singing technique of “vibrato”, “shakuri”, “fist”, “farset”, “tsukkomi”, “for” and “breathing” is used. ) Of these, “vibrato” and “shrimp” are detected based on the pitch calculated from the audio data. “Fist” and “Falset” are detected based on the spectrum calculated from the audio data. Further, “for” and “tsukkomi” are detected based on the pitch calculated from the audio data and the accompaniment data. Further, “breathing” is detected based on the power calculated from the audio data and the accompaniment data.

Based on the correspondence between the audio data and the accompaniment data, and the pitch calculated from the audio data, the CPU 11 determines the sound start time included in the audio data and the sound start time of the accompaniment data corresponding to the sound. Identify different sections. Here, the CPU 11 is a section where the pitch change timing of the audio data appears earlier than the pitch change timing of the accompaniment data, that is, the start time of the sound included in the audio data corresponds to the sound of the accompaniment data corresponding to the sound. For a section earlier than the start time, this section is specified as a section in which the “Tsukumi” singing technique is used. The CPU 11 stores the time information of the identified section and the identification information indicating “tsutsumi” in association in the singing technique data storage area 14 c of the storage unit 14.
On the contrary, the CPU 11 shows that the pitch change timing of the audio data appears later than the pitch change timing of the accompaniment data based on the correspondence between the audio data and the accompaniment data and the pitch calculated from the audio data. That is, a section where the start time of the sound included in the sound data is later than the start time of the sound of the accompaniment data corresponding to the sound, and the section where the singing technique of “for” is used as the detected section To be identified.

  Further, the CPU 11 analyzes the pattern of the temporal change of the pitch calculated from the audio data, detects a section where the pitch continuously fluctuates within a predetermined range above and below the center frequency, and detects it. This section is identified as a section in which the “vibrato” singing technique is used.

  Further, the CPU 11 analyzes the pattern of the temporal change of the pitch calculated from the audio data, detects a section in which the pitch continuously changes from a low pitch to a high pitch, and sings the detected section as a “shrimp” song. Identifies the interval in which the technique is used. This process may be performed based on the correspondence with the accompaniment data. In other words, the CPU 11 may detect a section in which the pitch of the audio data is continuously approaching the pitch of the accompaniment data from a low pitch based on the correspondence relationship between the audio data and the accompaniment data.

  Further, the CPU 11 is a section where the accompaniment data is sound and the power value of the audio data is higher than a predetermined threshold based on the correspondence between the audio data and the accompaniment data and the power calculated from the audio data. A small section is detected, and the detected part is specified as the "breathing" section.

Further, the CPU 11 analyzes the temporal change pattern of the spectrum calculated from the audio data, detects a section where the spectral characteristics are abruptly changed to the predetermined change state, and detects the detected section as “ It is specified that the section uses the “Falset” singing technique. Here, the predetermined change state is a state in which the harmonic component of the spectrum characteristic is extremely reduced. For example, as shown in FIG. 5, in the case of a local voice, many harmonic components are included (refer to FIG. 5A), but when a falset is formed, the magnitude of the harmonic components becomes extremely small (FIG. b)). In this case, the CPU 11 may also refer to whether or not the pitch has changed significantly upward. The falset is sometimes used even when generating the same pitch as the local voice, but is generally a technique used when generating high-pitched sounds that cannot be generated by the local voice. Therefore, “Falset” may be detected only when the pitch of the audio data is equal to or higher than a predetermined pitch. In addition, since the pitch range using the falset is generally different between male voice and female voice, gender detection is performed based on the voice data range and formants detected from the voice data, and based on this result, the pitch range for falset detection is determined. It may be set.
In addition, the CPU 11 detects a section in which the mode of change of the spectrum characteristic is variously switched in a short time, and identifies the detected part as a part where the “fist” singing technique is used. In the case of “fist”, it is a singing technique that adds a taste that changes the voice color and utterance method in a short section, so the spectral characteristics change variously in the section where this technique is used. .
As described above, the CPU 11 detects the section in which each singing technique is used from the voice data, associates the time information indicating the detected section with the identification information indicating the singing technique, and sings in the storage unit 14. The data is stored in the technique data storage area 14c. By this processing, the generated singing technique data is output.

  After finishing the singing technique data generation process, the CPU 11 of the authoring apparatus 1 stores the accompaniment data stored in the accompaniment data storage area 14a, the audio data stored in the audio data storage area 14b, and the singing technique data storage area 14c. The singing technique data and the lyrics data stored in the lyrics data storage area 14 d are combined to generate content in a predetermined format as shown in FIG. 4 and store it in the storage unit 14. At this time, instead of storing in the storage unit 14, the generated content may be transmitted to another device via a communication network or the like. In short, the CPU 11 may add singing technique data to at least one of audio data, accompaniment data, and lyrics data and output the content as content.

  Thus, according to this embodiment, the singing technique used by the singer can be automatically extracted from the voice data indicating the singer's voice. Moreover, the content containing the song technique data which show the extracted song technique can be created. If this content is used, the point of the singing technique can be displayed together with the lyric display in, for example, karaoke equipment, and thereby the singing technique used by the singer can be notified to the user of the karaoke equipment. . Moreover, you may make it evaluate a singer's singing ability based on this singing technique data.

Here, the specific example of the karaoke authoring tool using the content produced | generated by this embodiment is demonstrated below.
FIG. 6 is a diagram illustrating an example of a screen displayed in a karaoke authoring tool (karaoke tool) using content generated in the present embodiment. In the screen shown in FIG. 6, the content illustrated as a specific example in FIG. 4 is used. The controller of the karaoke authoring tool displays the screen shown in FIG. 6 based on the supplied content. Specifically, the control unit of the karaoke authoring tool displays the lyrics A1 based on the lyrics data included in the content, and the pitch of the audio data corresponding to the lyrics A1 based on the audio data included in the content. A graph A2 showing a temporal change is displayed. Further, the control unit displays a graph A3 indicating a temporal change in the pitch of the accompaniment data based on the accompaniment data included in the content. In addition, the control unit displays a time axis A4 corresponding to the progress of the music and specifies (detects) the tracks A51 to A55 for each singing technique, and in each track, based on the specified singing technique section. The two-way arrow is displayed in the section where the singing technique corresponding to the track is used. For example, the two-way arrow A541 displayed on the track A54 of “Vibrato” is displayed in the section corresponding to the lyrics “Chi”, indicating that the “Vibrato” technique is used in this section.

In this way, since the singing technique used by the singer is displayed on the screen, the user of the system, that is, the karaoke content creator, visually grasps the singing technique (vibrato, trial, etc.) used in the song. can do. If a karaoke system using such content is used, the user can visually grasp the singing technique used by the model singer, so the user can imitate the model singing technique. It becomes easy to sing.
The system using content according to the present embodiment is not limited to the karaoke authoring tool described above, and can be suitably used in a karaoke system (for example, a musical instrument karaoke system) or a singing practice system.

The present invention is not limited to voice data representing a person's voice, and can also be applied to voice data representing the performance of a musical instrument. Also in this case, the CPU of the authoring device detects and detects the section in which the performance technique (for example, vibrato, breath breathing, etc.) is used from the performance data of the musical instrument in the same manner as in the above-described embodiment. What is necessary is just to produce | generate the performance technique data which show an area. That is, the sound data may be sound data representing a human singing voice or sound data representing a performance sound of a musical instrument. The technique data may be technique data representing a technique in singing, or may be technique data representing a musical performance technique.

(2) In the above-described embodiment, the lyric data corresponding to the voice data is input by the operator using the operation unit, but instead, the CPU of the authoring apparatus performs the processing on the voice data. Voice recognition processing may be performed to automatically generate lyrics data from the voice data. In this case, the CPU may collate the accompaniment data with the pitch data extracted from the audio data, and automatically assign which lyrics are sung at which timing.

(3) In the above-described embodiment, the authoring device 1 automatically performs content generation. Instead, the operator operates the operation unit 17 to input or change data. You may make it perform. Specifically, for example, in the singing technique data generation process, when the CPU 11 detects a section in which the singing technique is used, a graph or the like indicating the section may be displayed on the display unit. In this case, the worker can confirm the section in which the singing technique is used by confirming the content displayed on the display unit. At this time, if the worker finds an erroneous detection or the like, the worker can operate the operation unit 17 to delete or correct the section.

(5) In the above-described embodiment, “vibrato” or “for” is detected as a singing technique, but the singing technique (or performance technique) to be detected is limited to that shown in the above-described embodiment. For example, it may be a staccato or a crescendo (decrescendo). Specifically, a section in which the power detected from the audio data appears strongly only for a certain short period may be detected as a staccato. Further, a section in which the power data value gradually increases (decreases) continuously may be detected as crescendo (decrescendo). In short, the pattern of the temporal change in pitch, spectrum, and power calculated from the audio data is analyzed to determine whether or not this analysis result corresponds to a predetermined pattern. What is necessary is just to specify the area corresponding to a pattern as an area where a specific technique is used.
