This practicer voice data is also in a data format such as WAVE format or MP3 format. In the instruction data storage area 126, instruction data representing instruction contents of singing is stored for each evaluation section.

<B: Operation of Embodiment>
Next, the operation of this embodiment will be described. First, the practitioner operates the operation unit 14 of the karaoke apparatus 1 to perform an operation of selecting a song to be sung. The operation unit 14 outputs an operation signal corresponding to the operated content to the control unit 11, and the control unit 11 selects music according to the operation signal output from the operation unit 14. Next, the control unit 11 causes the display unit 13 to display a screen that prompts selection of a practice course. FIG. 3 is a diagram illustrating an example of a screen displayed on the display unit 13. As shown in the drawing, on this screen, a screen for selecting one of the “phrase-by-phrase practice course”, “normal karaoke + partial practice course”, and “point practice course” is displayed. The “Practice Course for Each Phrase” is a course in which phrases are practiced in order by repeating reproduction of a model, singing, and guidance screen for each phrase (singing section). The “normal karaoke + partial practice course” is a course in which singing is performed as in normal karaoke, and a guidance screen is displayed by the input of the practitioner when it becomes a location where guidance is desired. The “point practice course” is a course for jumping to an arbitrary part of a song and practicing the jumped part.

  The practitioner confirms the screen displayed on the display unit 13 and operates the operation unit 14 to select a practice course. The operation unit 14 outputs an operation signal corresponding to the operated content to the control unit 11, and the control unit 11 determines the course selected according to the operation signal output from the operation unit 14, and the selected course The operation according to is performed.

<B-1: Operation when “Practice Course for Each Phrase” is selected>
First, processing when “Practice Course for Each Phrase” is selected will be described with reference to the flowchart shown in FIG. If the lyrics and instruction content are displayed in phrase units (single section units), there are the following problems. The resolution of the karaoke screen is usually not very high (about VGA (Video Graphics Array)), so if the phrase is long, it will not be possible to enter the instruction screen, while if the phrase is short, it is difficult to sing (it is difficult to practice singing). Therefore, in this embodiment, the singing unit and the evaluation unit are separated.

  When it is determined that the “practice course for each phrase” is selected, the control unit 11 first reproduces a model voice for each singing section (step S1). At this time, the control unit 11 can also reproduce the accompaniment sound in accordance with the model voice. Next, the controller 11 performs karaoke accompaniment by causing the speaker 17 to emit the accompaniment sound represented by the accompaniment data stored in the accompaniment data storage area 121 for each predetermined singing section (step S2). That is, the control unit 11 reads the accompaniment data from the accompaniment data storage area 121 and supplies the accompaniment data to the audio processing unit 16. The audio processing unit 16 converts the accompaniment data into an analog signal and supplies the analog signal to the speaker 17 to emit sound. . Further, the control unit 11 reads out the lyrics data from the lyrics data storage area 122 and causes the display unit 13 to display the lyrics telop.

  The practitioner sings along with the accompaniment emitted from the speaker 17. At this time, the voice of the practitioner is picked up by the microphone 15 and converted into a voice signal, which is output to the voice processing unit 16. The trainer speech data (second speech data) A / D converted by the speech processing unit 16 is stored (recorded) in the trainer speech data storage area 125 in time series together with information indicating the elapsed time from the start of accompaniment. (Step S3).

  Next, the control unit 11 compares the model voice data stored in the model voice data storage area 124 with the trainer voice data output from the voice processing unit 16, and based on the comparison result, the trainer voice data. Are evaluated for each evaluation section shorter than the singing section (step S4).

Here, the evaluation process performed by the control unit 11 in step S4 will be described in detail below. The control unit 11 detects the pitch, power, and spectrum of the model voice data and the practice person voice data in units of frames each having a predetermined time length (for example, “3 msec”). FFT (Fast Fourier Transform) is used for spectrum detection. In this embodiment, the pitch, power, and spectrum of the model voice data (or the practicer voice data) are referred to as “features” of the model voice data (or the practicer voice data).
Subsequently, the control part 11 calculates | requires the correspondence of both based on both spectrums detected from model audio | voice data and practitioner audio | voice data. There is a possibility that the model voice and the trainer voice are shifted in time. In this way, even if the model voice and the trainer voice are shifted forward and backward in time, time normalization (DTW) is performed so that the time axis of the trainer voice data is expanded and contracted so that they can be associated with each other. : Dynamic Time Warping) and adjust the time axis of both. As a technique for performing this DTW, DP (Dynamic Programming) is used in this embodiment.
Next, the control unit 11 compares the characteristics of the model voice data with the characteristics of the practitioner voice data, and evaluates the practitioner voice data for each evaluation section according to the degree of separation between the two. Specifically, for example, each feature of pitch, power, and spectrum may be compared, and evaluation (scoring) may be performed for each feature according to the degree of separation.

Returning to the description of FIG. The control part 11 alert | reports an evaluation result by displaying the evaluation result in step S5 on the display part 13 for every evaluation area (step S5). At this time, the control part 11 can also read the instruction | indication data corresponding to the evaluation area from the instruction | indication data storage area 126, and can also display the instruction | indication content which the read instruction | indication data represents on the display part 13 for every evaluation area.
The method of notifying the evaluation result is not limited to display, and may be notified by emitting a voice message indicating the evaluation result. In short, any method may be used as long as the evaluation result is notified. Also good.

FIG. 5 is a diagram illustrating an example of a screen displayed on the display unit 13 in step S5. As shown in the figure, the lyrics W1 included in one evaluation section are displayed, comments C1 to C4 representing teaching contents of the evaluation section, figures I10 to I14 representing singing techniques to be used in the evaluation section, The lyrics, instruction contents, and evaluation results corresponding to the evaluation section, such as graphics H1 to H9 (for example, “×” and “◯”) indicating the corresponding evaluation results, are displayed.
At this time, the control unit 11 adjusts the pitch A of the trainer voice and the graph A1 showing the temporal change in the pitch of the model voice as shown in FIG. It is also possible to display a graph A2 showing temporal changes. Further, as shown in FIG. 5, a graphic A3 representing the rhythm of the model voice and a graphic A4 representing the rhythm of the trainee voice can be displayed. Further, in order to compare the difference in volume and rhythm between the model voice and the practice person voice, the lyrics W2 corresponding to the practice person voice can be displayed together with the lyrics W1 corresponding to the model voice.

  Next, the control unit 11 determines whether or not there is a next evaluation section (step S6). If there is a next evaluation section (step S6; YES), the control unit 11 returns to the process of step S4 and performs the next evaluation. The section is evaluated (step S4), and the evaluation result is notified by displaying the screen illustrated in FIG. 5 on the display unit 13 (step S5). That is, the control unit 11 evaluates the trainer voice data for each evaluation section by repeating the processes of steps S4 to S6, and notifies the evaluation result. On the other hand, when it is determined that there is no next evaluation section, that is, it has been evaluated to the end of the singing section (step S6; NO), the control unit 11 determines whether there is a next singing section ( If it is determined in step S7) that there is a next singing section (step S7; YES), the process returns to step S1 to reproduce the model voice of the singing section (step S1). If it is determined in step S7 that there is no next singing section, that is, it has been played back to the end of the song (step S7; NO), the control unit 11 ends the process.

  When the control unit 11 performs the process shown in FIG. 4, “reproduction of a model voice in a singing section” → “singing practice in a singing section” → “evaluation result display in an evaluation section”. Repeated. Thus, in this embodiment, since the singing section unit for performing the singing practice and the evaluation section unit for displaying the evaluation result are separated, the singing practice can be easily performed, and the evaluation result is obtained. Easy to display.

<B-2: Operation when “normal karaoke + partial practice course” is selected>
In the “Practice Course for Each Phrase” described above, reproduction of a model voice, singing, and evaluation are performed for all parts of the song. On the other hand, the practitioner wants to practice only a part of the song, and the other part may want to sing through like ordinary karaoke. This “normal karaoke + partial practice course” is used in such a case.

FIG. 6 is a flowchart showing a flow of processing performed by the control unit 11 when it is determined that “normal karaoke + partial practice course” is selected. When it is determined that “normal karaoke + partial practice course” has been selected, first, the control unit 11 displays lyrics telop on the display unit 13 and starts karaoke accompaniment (step S11). That is, the control unit 11 reads the accompaniment data from the accompaniment data storage area 121 and supplies the accompaniment data to the audio processing unit 16. The audio processing unit 16 converts the accompaniment data into an analog signal and supplies the analog signal to the speaker 17 to emit sound. . Further, the control unit 11 reads out the lyrics data from the lyrics data storage area 122 and causes the display unit 13 to display the lyrics telop.
FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 13 when “normal karaoke + partial practice course” is selected. As illustrated, the display unit 13 displays a lyrics telop W3.
The practitioner sings along with the accompaniment emitted from the speaker 17. At this time, the voice of the practitioner is picked up by the microphone 15 and converted into a voice signal, which is output to the voice processing unit 16. The trainer speech data A / D converted by the speech processing unit 16 is stored (recorded) in time series in the trainer speech data storage area 125 together with information indicating the elapsed time from the start of accompaniment (step S12). .

In this “normal karaoke + partial practice course”, the control unit 11 causes the display unit 13 to display a button B1 for shifting to the partial practice mode, as shown in FIG. When the button B1 is selected by the practitioner operating the operation unit 14, the operation unit 14 outputs a signal corresponding to the operation content to the control unit 11. The control unit 11 shifts to the partial practice mode according to the operation signal output from the operation unit 14. The control unit 11 functions as an input receiving unit that receives an operation signal input from the operation unit 14 while an accompaniment sound is being emitted from the speaker 17. When the operation signal is input, that is, when it is determined to shift to the partial practice mode (step S13; YES), the control unit 11 sets the instruction data corresponding to the evaluation section of the accompaniment sound that has been emitted as instruction data. The instruction contents read from the storage area 126 and indicated by the read instruction data are displayed on the display unit 13 for notification (step S14).
Note that the guidance content notification method is not limited to display, and may be notified by emitting a voice message indicating the guidance content. In short, any method may be used as long as the guidance content is notified. Also good.

  FIG. 8 is a diagram illustrating an example of a screen displayed in step S14. As shown in the figure, the lyrics W4 included in one evaluation section are displayed, and the evaluation sections such as comments C1 and C2 representing the guidance contents of the evaluation section and figures I1 to I4 representing the singing technique to be used in the evaluation section. The lyrics and instruction contents corresponding to are displayed.

  Moreover, the control part 11 reproduces | regenerates the accompaniment of a song area by emitting the accompaniment sound of the song area corresponding to the instruction | indication content displayed on the display means from the speaker 17 (step S15).

  When the reproduction of the accompaniment in the singing section is finished, the control unit 11 determines whether or not to end the partial practice mode (step S16). In this determination, for example, whether or not the practitioner has performed an operation to end the partial practice mode is determined by an operation signal output from the operation unit 14. When it determines with complete | finishing partial practice mode (step S16; YES), the control part 11 returns to the process of step S11, and restarts karaoke accompaniment (step S11). On the other hand, when it is determined not to end the partial practice mode (step S16; NO), the control unit 11 returns to the process of step S14 and repeats the partial practice.

  In Step S13, when it is determined that the mode does not shift to the partial practice mode (Step S13; NO), the control unit 11 determines whether or not the song is finished (Step S17), and the song is finished. If it is determined (step S17; YES), the process is terminated as it is. On the other hand, if it is determined that the song is not completed (step S17; NO), the process returns to step S11, and karaoke is performed. Accompaniment is resumed (step S11).

  In this "normal karaoke + partial practice course" course, if the practitioner sings without any particular operation, the singing can be continued in the same way as normal karaoke, but places where you want to practice or where you cannot sing well When an operation such as pressing a predetermined key is performed, the instruction screen is displayed, and the practitioner can practice the phrase (singing section) again by watching it. When the practice of the singing section is finished, the practitioner can resume normal singing again by operating the operation unit 14.

<B-3: Operation when “Point practice course” is selected>
In the “Point Practice Course”, you can jump to the point you want to practice and practice the singing section.
FIG. 9 is a flowchart showing a flow of processing performed by the control unit 11 when it is determined that the “point practice course” is selected. If it is determined that the “point practice course” has been selected, the control unit 11 causes the display unit 13 to display a list for each song section of the lyrics stored in the lyrics data storage region 122 (step S21).
FIG. 10 is a diagram illustrating an example of a screen displayed in step S21. In the figure, each line L1 to L5 displays lyrics for each singing section.

  The practitioner operates the operation unit 14 to move the cursor, thereby selecting a phrase (singing section) to be practiced. The operation unit 14 outputs an operation signal corresponding to the operated content to the control unit 11. The control unit 11 selects one of lyrics (singing section) for each singing section displayed on the display unit 13 in accordance with the operation signal output from the operation unit 14 (step S22). The control unit 11 reads out the model voice data corresponding to the selected singing section of the lyrics from the model voice data storage area 124, and emits the model voice represented by the read model voice data from the speaker 17 (step S23). At this time, the control unit 11 can also emit the accompaniment sound represented by the accompaniment data corresponding to the reproduced model voice from the speaker 17 in accordance with the reproduction of the model voice.

Specifically, for example, when the cursor is moved to the line L4 on the screen shown in FIG. 10, the control unit 11 reproduces the model voice and the accompaniment corresponding to the singing section of the lyrics of the line L4.
As described above, when the phrase is selected, by reproducing the model voice for each phrase, it is easier to understand which part is the jump destination than only looking at the lyrics. Thereby, the operativity at the time of a practitioner practicing a song can be improved.

  The practitioner operates the operation unit 14 to move the cursor, and performs an operation for determining selection of a singing section to be practiced with reference to the displayed lyrics and a model voice that is emitted as the cursor moves. Do. The control unit 11 determines whether or not the selection of the singing section has been determined in accordance with the operation signal supplied from the operation unit 14 (step S24). If it is determined that it has not been determined (step S24; NO), the control unit 11 returns to the process of step S21, and corresponds to the singing section selected (displayed by the cursor) with the display of the singing section. Play sample audio. On the other hand, when it is determined that the selection of the singing section is determined (step S24; YES), the control unit 11 displays the singing section displayed on the display unit 13 in accordance with the operation signal supplied from the operation unit 14. The selection of any one of the lyrics is determined (step S25). The control unit 11 reads the accompaniment data corresponding to the singing section of the lyrics determined to be selected from the accompaniment data storage area 121, causes the speaker 17 to emit the accompaniment sound represented by the read accompaniment data, and the accompaniment to be emitted The lyrics data corresponding to the sound is read from the lyrics data storage area 122, and the lyrics represented by the read lyrics data are displayed on the display unit 13 for each evaluation section, thereby performing karaoke accompaniment in the determined singing section (step S26). ).
