DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus having a singing special training function for practicing a song while performing a step for each phrase.

[0002]

2. Description of the Related Art There is a karaoke apparatus having a special function for singing practice. For example, JP-A-8-30538
No. 5 discloses a cassette tape or CD in which lyrics and singing points are recorded immediately before a place to be sung in addition to karaoke accompaniment music. According to this, even if the user does not remember the lyrics, he / she can easily practice karaoke without seeing the lyrics card or the like and understanding the points of singing. In the karaoke apparatus described in JP-A-2000-122672, after a singer's singing is reproduced simultaneously with karaoke accompaniment music for each song phrase,
The performance of only the accompaniment music for the same phrase is executed. According to this, singing can be effectively practiced by first listening to the singing by the singer and learning the singing method for each phrase, and then singing the same phrase without listening to the singing by the singer.

[0003]

Among the practice functions as described above, particularly, those which can be uttered immediately after listening to a professional exemplary singing can be efficiently performed while imitating the exemplary singing method. The practice effect is high because you can learn songs. However, even if you think that you can sing well, you do not know if you can sing well objectively. Karaoke devices with a singing score function are also in widespread use, but it is unsatisfactory from the viewpoint of practice because it is not clear where to fix even if only the scoring result is shown. If you can immediately point out what was good and where it was short, you will be able to understand and practice efficiently. In addition, I would like to practice repeatedly for difficult phrases that are difficult to sing, and on the contrary, I want to omit the practice of phrases that can already be sung. However, since it depends on the person where the difficulty is felt, for example, even if the number of times of reproduction of the difficult part is increased, it cannot be decided uniformly.

Accordingly, the present invention displays the evaluation result by comparing and grading the singing voice of the trainee with the model singing for each phrase,
The purpose of the present invention is to provide a karaoke apparatus having a singing special training function that can be practiced as much as desired.

[0005]

According to a first aspect of the present invention, there is provided a step performance control means for playing and temporarily stopping music data in phrase units which are appropriately set; Model singing selection output means for controlling whether to output model singing by voice when performing or karaoke performance without substantially outputting model singing, and associated with a phrase when playing a certain phrase of a certain song Display means for displaying advice information set to the practicer to the practicer, and scoring means for collecting the practicer's singing voice from the microphone and grading the singing skill when performing a karaoke performance of a certain phrase of a certain song And evaluation display means for displaying the result of the scoring of a phrase by the scoring means to a trainee after playing the phrase. That was singing special training function with a karaoke machine.

According to a second aspect of the present invention, in the first aspect, for a certain phrase i of a certain music piece, the phrase i is played with a model song and the advice information of the phrase i is displayed. The karaoke apparatus with singing special training function is characterized in that the karaoke performance of i is performed together with the scoring process, the scoring result is displayed subsequently, and the process proceeds to the same processing stage as described above for the next phrase (i + 1).

DESCRIPTION OF THE PREFERRED EMBODIMENTS === Basic Functions of Karaoke Apparatus =
== FIG. 1 shows a configuration example of a karaoke apparatus according to an embodiment of the present invention. A central control unit 1 including a CPU, a RAM, and a ROM controls and controls each peripheral component via a control bus.

The hard disk device 2 stores a large number of karaoke data including accompaniment music data and lyrics data of the karaoke music. Upon receiving the request via the operation control unit 3, the central control unit 1 processes the corresponding karaoke data according to the order of the request input. That is, karaoke data corresponding to the requested music is extracted from the hard disk drive 2 and the included karaoke accompaniment music data is transferred to the synthesizer 4 to generate karaoke accompaniment music. The generated karaoke accompaniment music and the singing voice collected by the microphone 5 are mixed by the mixing amplifier 6 and sound output from the speaker 7. The display 8 displays a background image input via the image control unit 9 and a lyric image with a color change of a portion to be sung.

=== Special Training Mode === In the karaoke apparatus according to the present embodiment, the karaoke data described above is expressed in an ADPCM format for outputting a professional singing voice such as an original singer along with karaoke accompaniment music. Model singing data is included.

Further, phrase designation data is prepared in association with the karaoke data. This is to indicate the unit of performance in the special training mode described later, and the phrase number and the start and end points of the section so as to be a natural break such as a breathing point or a lyric break when singing. Is specified (see FIG. 3). One bar of musical score data of accompaniment music may be defined as one phrase, or a performance corresponding to one line in lyrics display may be defined as one phrase. Therefore, for example, the first phrase is from the first bar to the second bar of the third bar of the musical score display, and the second phrase is the fifth bar from the third beat of the second bar, depending on the break of the meaning of the lyrics or the interlude section. Until the end of the knot, the third phrase can be divided into ten to thirteenth bar, and so on.

Further, advice information and evaluation data are prepared in association with the phrase designation data. The advice information is document image data for displaying, on the display 8 or the like, a message on the display 8 or the like, along with lyrics, on matters that require special attention when singing the phrase. For example, while presenting a lyric character string to be sung by the phrase, a note at the time of pronunciation is indicated while pointing to a character to be pronounced. The evaluation data may include data necessary for performing a singing evaluation of the phrase, which will be described later.

In the karaoke apparatus according to the present embodiment, a user can select a karaoke mode or a special training mode by inputting an operation from an operation panel or the like. For example, as shown in FIG. 4 (A), two modes are displayed side by side on the display 8 before the music selection, and the selection can be made by placing the cursor on one of the modes and pressing the set key. When a karaoke mode is selected and a music selection number is entered, karaoke accompaniment music of the selected music is played as in the existing karaoke apparatus. When the special training mode is selected here, the central control unit 1 starts the special training process shown in FIG.

=== Performance with Model Song and Advice Display =
== In the central control unit 1 in which the special training mode is selected and the special training process is started, first, the display 8 prompts the user to input a music number. The user inputs the music number of the music to be practiced from the operation panel or the like (step 10 in FIG. 2).
After confirming 1) and (step 102), the processing of the first phrase is started.

First, a message is displayed on the display 8 based on the lyrics and advice information corresponding to the first phrase. (See FIG. 4B). For example, while showing the lyrics for one phrase, "Somebody is waiting, always waiting", "Like [while someone is waiting] whisper" A message such as "Be careful because it is easy to remove" or "Be careful of the starting position of [Waiting] in [Always waiting]. Let's listen to the model singing well and grasp the rhythm" (step 104 in FIG. 2) ).

While displaying the advice information, the karaoke accompaniment music data corresponding to the first phrase and the model singing data are synchronized and output as sound, thereby performing the model singing performance (step 105), and then temporarily stopping the performance. I do. At the same time as the stop, a message for selecting whether or not to repeat this is displayed on the display 8 (step 106). 1 again if the practitioner chooses to repeat
The advice display of the second phrase
When the display of the repetition selection is performed and the operation is stopped, and the user does not select the repetition, the following processing is performed.

=== Karaoke Performance with Singing Evaluation === When the repetition of the model performance with singing is stopped, the start of the karaoke performance is confirmed (step 107), and the karaoke accompaniment music corresponding to the first phrase is played. With
The singing voice of the trainee is collected from the microphone (step 108), and then the performance and voice collection are temporarily stopped.

For each of the collected singing voices, evaluation items such as utterance start timing / utterance end timing, average value of pitch, stability / variation width, and volume during the utterance period are detected and used as singing evaluation criteria. The data, for example, the main melody part of the accompaniment music data and the model singing data are compared and evaluated by an appropriate algorithm, and the result is displayed (step 109).

A specific embodiment will be described. First, the singing voice collected from the microphone is processed by voice recognition and frequency analysis, and the uttered character, its utterance start timing / utterance end timing, the average value and fluctuation range of pitch, etc. are obtained to obtain data to be evaluated. . On the other hand, from the main melody part and the lyrics data of the accompaniment music data, the character to be sung, its pitch, the timing to start uttering and the timing to end it can be known. By comparing these reference data with the singing voice data, the singer's utterance is numerically evaluated for each lyric character in terms of how much the utterance start timing, utterance end timing, average pitch and fluctuation range, etc. deviate from the reference And evaluate and analyze the accuracy.

Based on the evaluation result, the contents are transmitted to the singer in an easy-to-understand message. Here, several fixed phrases for displaying an evaluation message are prepared for each evaluation item, and the evaluation message is displayed by pointing to the pronounced character while presenting the lyrics characters of the sung phrase. For example, when the pitch average value is low, a fixed sentence “slightly higher sound of ○” is prepared, and the pronounced character is applied to the 部分 portion. On the display 8, while displaying the lyric character of the phrase "Let's decorate in the room on the day you can't meet", a message such as "Make the sound of [ju] a little higher" is displayed, and pay particular attention Point out what should be done. Similarly, if the utterance timing is shifted to the front, "Sound of [Let's go ahead. Let's calm down." ] Should be cut off exactly. ",
Otherwise, if the pitch is unstable, the pitch of [Let's play] is unstable, and if the volume is not enough, the sound of [Heya] is clearly loud. Displays an evaluation message.

Here, evaluation items and fixed phrases to be compared and evaluated for each phrase may be set in advance in the evaluation data, and the singing evaluation and the result display may be performed in accordance with the evaluation items and the fixed phrases. For example, for phrases for which many people are likely to lose pitch, the average pitch value as an evaluation item in the evaluation data and the standard sentence "Evaluate the pitch average value slightly lower (higher)" when evaluating the pitch average value Is designated, and when the phrase is trained, the pitch is evaluated. Alternatively, specify each part of the phrase to be evaluated specifically and specifically, and analyze the average pitch of "Masho" and the timing of utterance start and utterance end for the phrase "Let's decorate in the room when you can't meet" To do
As a result of the analysis, if the length of each pronunciation is incorrect, the "rhythm of [shosho] is incorrect", or if the pitch of each pronunciation is incorrect, "the pitch of [shosho] is unstable. "
If the pitch, the utterance start timing, and the utterance end timing are all incorrect, it is also possible to set in advance the evaluation data to display "[Let's say] as the score" or the like.

After the evaluation message is displayed on the display 8, the trainee selects whether or not to repeat the above-described performance with model singing and the following karaoke performance with singing evaluation. The processing ends (steps 110 to 112), and the processing shifts to the processing of the next phrase (step 113). That is,
Start performance with advice display and model singing for the second phrase.

In this manner, the performance with the model singing and the karaoke performance with the singing evaluation are repeated until the trainee is satisfied.
When the processing is completed up to the last phrase of the song, the special training process for the song ends.

=== Second Embodiment === In the second embodiment, the selection of the phrase repetition as described above is not performed by the trainee, and the same phrase is repeated until the singing evaluation reaches a predetermined level or higher. Repeat practice. That is, a step of judging “whether it is equal to or more than a predetermined criterion” is added after the scoring result display (step 109 in FIG. 2). Karaoke performance (Step 108)
To 109). This may be incorporated into the previous embodiment as a guts mode, and the trainee may select the mode as appropriate. Similarly, a review mode may be provided in which the performance with model singing and the performance of karaoke with singing evaluation are performed once.

The display of advice may be omitted, for example, by selecting whether or not to display the advice. Practicers who practice many times and do not need advice can use it comfortably without any hassle.

=== Third Embodiment === In another embodiment, when a performance with model singing or a karaoke performance with singing evaluation is repeated a plurality of times, advice information displayed every time the number of repetitions is repeated, Make the evaluation message different. That is, different messages are displayed before and after the performance with the model singing, and before and after the performance and evaluation of the karaoke performance with the singing evaluation after the performance with the model singing. This can be easily realized by storing the number of repetitions, the display contents, and the evaluation contents in association with the advice information and the evaluation data. For example, while displaying the lyric character of the phrase, "Every time I think I'll forget, the mysterious heart will be awkward" Display advice information. After performing the performance with the model singing once, the second time after displaying more specific advice information such as "[Let's forget] singing with one beat. Listen to the model singing again." Perform with model singing. By displaying more specific advice information each time the practice is repeated, the practicer can listen to the model performance more carefully, thereby increasing the effect of the practice.

Next, when performing a performance with singing evaluation, 1
In the evaluation of the second singing, "[Let's forget] 's singing is too slow. It's half a beat earlier.' In the second singing,"[Let's forget] 's singing became accurate. Next "Be careful about singing [Mysterious]", and so on. It is also possible to display an evaluation reflecting the previous evaluation result. This allows the practitioner to receive a more elaborate evaluation and makes the singing lessons more effective.
