<First Embodiment>
A first embodiment of the present invention will be described below. FIG. 1 is a block diagram of a singing voice output control device 100 according to the first embodiment. The singing voice output control device 100 generates and outputs a voice signal indicating the singing voice of the lyrics designated by the user by segment-connected voice synthesis.

  For example, the singing voice output control device 100 is realized by an electronic musical instrument (for example, an electronic organ or an electronic piano). Note that the singing voice output control device 100 can also be realized by an information processing device connected to an electronic musical instrument via an interface. Alternatively, the singing voice output control device 100 can be realized by a single information processing device. That is, the singing voice output control device 100 is a stationary information processing device (for example, a desktop computer or a stationary game machine) or a portable information processing device (for example, a laptop computer, a tablet computer, a mobile phone, or It can also be realized by a portable game machine or the like.

  Below, as shown in FIG. 1, the case where the singing voice output control apparatus 100 is implement | achieved with the electronic musical instrument provided with the arithmetic processing part 10, the memory | storage part 12, the operation part 14, the sound emission part 16, and the display part 18 is demonstrated. . More specifically, a case where the singing voice output control device 100 is realized by an electronic organ will be mainly described as an example.

  The arithmetic processing unit 10 includes one or a plurality of microprocessors, and executes arithmetic processing based on the program PGM and various data stored in the storage unit 12. The storage unit 12 includes one or a plurality of recording media (for example, a semiconductor recording medium or a magnetic recording medium). For example, the program PGM executed by the arithmetic processing unit 10 and various data used by the arithmetic processing unit 10 are stored in the storage unit 12.

  The operation unit 14 is for accepting a user operation, and includes one or a plurality of operation elements operated by the user. For example, the operation unit 14 is for receiving a user's performance operation, and includes a plurality of performance operators (for example, keys and strings). As shown in FIG. 1, the operation unit 14 includes a first operation unit 30 and a second operation unit 32. For example, if the singing voice output control device 100 is realized by an electronic organ having a first keyboard and a second keyboard, the first keyboard corresponds to the first operation unit 30 and the second keyboard is a second operation. It corresponds to the section 32.

  The sound emitting unit 16 is a speaker or a headphone, for example, and radiates a sound wave corresponding to the sound signal supplied from the arithmetic processing unit 10. The display unit 18 is, for example, a liquid crystal display or an organic EL display, and displays a screen based on the control of the arithmetic processing unit 10.

  In the singing voice output control device 100, the singing voice of the lyrics specified by the user is synthesized and outputted, and in particular, the user selects a chord (a sound composed of three or more sounds having different pitches). You can specify the lyrics by playing. Hereinafter, such a function will be described.

  As shown in FIG. 1, the speech unit group G and the correspondence data D are stored in the storage unit 12 as data for realizing the above functions.

  The speech unit group G is a set (speech synthesis library) of a plurality of speech units used as a material for generating a speech signal. A phoneme segment is a phoneme (for example, a vowel or a consonant) that is the smallest unit that can distinguish linguistic meaning, or a phoneme chain (for example, a diphone or a triphone) that connects a plurality of phonemes.

  The correspondence data D is data in which chord information is associated with pronunciation content information indicating the pronunciation content. FIG. 2 shows an example of the correspondence data D. In the correspondence data D shown in FIG. 2, one chord is associated with one phonetic character (phonetic symbol), and the phonetic character (phonetic symbol) and the chord are correlated one-to-one. . In the correspondence data D shown in FIG. 2, the phonetic characters (phonetic symbols) correspond to the phonetic content information.

  In the example shown in FIG. 2, a chord root note (for example, C, C #, D, etc.) is associated with each line of 50 Japanese sounds, and five types of codes (major code, minor code, and seventh code). , Minor seventh code, major seventh code) are associated with each character in each line. In other words, the root of the chord is associated with the consonant (k, s, t, n, h, m, y, r, w), and the above five types of chords are the vowels (a, i, u, e). , O), respectively. For example, in the example shown in FIG. 2, chords “C”, “Cm”, “C7”, “Cm7” are respectively added to the phonetic characters “A”, “I”, “U”, “E”, “O” belonging to that row. ”And“ CM7 ”. In the example shown in FIG. 2, the phonetic characters "ka", "ki", "ku", "ke", and "ko" belonging to the line are respectively chords "C #", "C # m", and "C #". 7 ”,“ C # m7 ”, and“ C # M7 ”are associated with each other. As described above, in the example shown in FIG. 2, these pronunciation characters “a”, “i”, “u”, “e”, “o”, “ka”, “ki”, “ku”, “ke” "," "Ko", etc. each correspond to an example of pronunciation content information. As described above, in the example shown in FIG. 2, the root of the chord is associated with each line of 50 Japanese sounds, and five types of codes are associated with each character in each line. This makes it easier for the user to understand the correspondence between chords and pronunciation characters.

  In the example shown in FIG. 2, tension codes such as adnain (add9), ad elevens (add11), and adflat nines (add ♭ 9) are associated with muddy sound, semi-turbid sound, and stuttering sound, respectively. For example, a chord “D” is associated with “sa”, and a chord “D7 (add9)” is associated with “za”, which is the muffled sound of “sa”. For example, chord “F” is associated with “ha”, and chord “F (add11)” is associated with “pa”, which is a semi-turbid sound of “ha”. Further, for example, the chord “D # (add ♭ 9)” is associated with the chord that belongs to the line, and the chord “D # m (add ♭ 9)” is associated with “chu”. , “Cho” is associated with the chord “D # 7 (add 9)”. In the example shown in FIG. 2, these pronunciation characters “za”, “pa”, “cha”, “chu”, “cho”, and the like correspond to examples of pronunciation content information.

  In the singing voice output control device 100, the user can designate lyrics by playing chords by using the correspondence data D described above. Here, a performance operation performed by the user for designating lyrics will be described with reference to FIGS. FIG. 3 is a musical score showing an example of a performance operation performed by the user for designating lyrics. In FIG. 3, it is assumed that the lyrics “I wonder if it will be fine tomorrow” in Japanese are specified. Note that the chords shown in FIG. 3 indicate chords associated with the characters constituting the lyrics (see FIG. 2), and are not chords for accompaniment. FIG. 4 is a diagram for explaining an example of a performance operation performed by the user for designating the lyrics. In FIG. 4, it is assumed that a part “ASU” meaning “Tomorrow” is specified in Japanese in the lyrics. In FIG. 4, the t-axis indicates the time axis.

  When designating lyrics, the user plays the first keyboard (first operation unit 30) with one hand (for example, the left hand) and the second keyboard (second operation unit 32) with the other hand (for example, the right hand). To do. First, the user designates “A” as the first character of the lyrics using the first keyboard. As shown in FIG. 2, the chord “C” is associated with the phonetic character “A”. For this reason, as shown in FIG. 4, the user presses the key corresponding to the chord “C” on the first keyboard. Furthermore, in this state, the user designates the pitch when the sound of “A” is emitted using the second keyboard. In the example shown in FIG. 3, “Fa” is designated as the pitch when the sound “A” is emitted. In this case, as shown in FIG. 4, the user presses the “Fa” key on the second keyboard. In this case, the singing voice of “A” having the pitch of “Fa” is synthesized and emitted from the sound emission unit 16.

  Next, the user designates “su” as the second character of the lyrics using the first keyboard. As shown in FIG. 2, the chord “D7” is associated with the phonetic character “su”. For this reason, as shown in FIG. 4, the user presses the key corresponding to the chord “D7” on the first keyboard. Further, in this state, the user designates the pitch when the sound of “su” is emitted using the second keyboard. In the example shown in FIG. 3, “La” is designated as the pitch when the sound of “su” is emitted. In this case, as shown in FIG. 4, the user presses the “L” key on the second keyboard. In this case, the singing voice of “su” having the pitch “ra” is synthesized and emitted from the sound emitting unit 16. Thereafter, the user designates the third and subsequent characters of the lyrics in the same manner as described above.

  In the correspondence relationship data D shown in FIG. 2, chords are not associated with the prompt sounds, but the prompt sounds can be emitted as described below. For example, if the singing voice of “Tat”, which is the sound of “T”, is to be emitted, the user uses a key corresponding to the chord “D #” associated with the phonetic character “T” on the first keyboard. After pressing the key corresponding to the pitch at which the sound of “ta” is released on the second keyboard, the finger is released from the first keyboard and the second keyboard immediately after the key is pressed. Can be released.

  As described above, in the singing voice output control device 100, the user can designate lyrics by playing chords. Such a lyrics designating function is realized when the arithmetic processing unit 10 executes processing based on the program PGM and the correspondence data D stored in the storage unit 12. That is, as shown in FIG. 1, the chord information acquisition unit 20, pitch information acquisition unit 22, pronunciation content information acquisition unit 24, singing voice output control unit 26, and singing voice synthesis unit 28 are realized by the arithmetic processing unit 10. As a result, the above-described lyrics designating function is realized. The chord information acquisition unit 20, the pitch information acquisition unit 22, the pronunciation content information acquisition unit 24, the singing voice output control unit 26, and the singing voice synthesis unit 28 can also be realized by being distributed over a plurality of integrated circuits. In addition, some or all of these can be realized by a dedicated electronic circuit (DSP).

  The chord information acquisition unit 20 acquires chord information indicating the chord input using the first operation unit 30. For example, the chord information acquisition unit 20 acquires chord information indicating a chord played using the first keyboard (first operation unit 30). For example, in the singing voice output control apparatus 100, first performance operation data indicating the performance content (for example, the key pressing state of each key) being performed on the first keyboard is supplied to the arithmetic processing unit 10. Based on the first performance operation data, the chord information acquisition unit 20 determines whether or not a chord is being played on the first keyboard, and identifies the type of chord being played on the first keyboard.

  The pitch information acquisition unit 22 acquires pitch information indicating the pitch input using the second operation unit 32. For example, the pitch information acquisition unit 22 acquires pitch information indicating the pitch played using the second keyboard (second operation unit 32). For example, in the singing voice output control device 100, second performance operation data indicating the performance content (for example, the key pressing state of each key) being performed on the second keyboard is supplied to the arithmetic processing unit 10. Based on the second performance operation data, the pitch information acquisition unit 22 specifies the key pressed by the user on the second keyboard and specifies the pitch corresponding to the key.

  The pronunciation content information acquisition unit 24 acquires the pronunciation content information associated with the chord information acquired by the chord information acquisition unit 20 based on the correspondence data D stored in the storage unit 12. For example, the pronunciation content information acquisition unit 24 refers to the correspondence data D shown in FIG. 2 and acquires the pronunciation character (pronunciation content information) associated with the chord specified by the chord information acquisition unit 20.

  The singing voice output control unit 26 emits the singing voice based on the pronunciation content information acquired by the pronunciation content information acquisition unit 24 and the pitch information acquired by the pitch information acquisition unit 22. Sound). That is, the singing voice output control unit 26 emits the singing voice of the pronunciation character indicated by the pronunciation content information from the sound emitting unit 16 at a pitch corresponding to the pitch information.

  For example, the singing voice output control unit 26 supplies the singing voice information and the pitch information to the singing voice synthesizing unit 28, so that it is the singing voice of the pronunciation character indicated by the pronunciation content information and corresponds to the pitch information. A singing voice having a pitch is generated by the singing voice synthesizing unit 28 and emitted from the sound emitting unit 16.

  In this case, the singing voice synthesizing unit 28 reads the waveform data of the speech unit corresponding to the phonetic character from the speech unit group G. In addition, the singing voice synthesizing unit 28 performs pitch conversion on the waveform data of the read speech segment so that the pitch corresponds to the pitch information. Then, the singing voice synthesizing unit 28 emits the singing voice from the sound emitting unit 16 based on the waveform data after the pitch conversion.

  In FIG. 1, the singing voice output control unit 26 and the singing voice synthesizing unit 28 are realized as separate functions, but the singing voice output control unit 26 and the singing voice synthesizing unit 28 are realized as one function. You may do it. That is, the function of the singing voice synthesizing unit 28 may be included in the singing voice output control unit 26.

  Next, an example of processing executed by the arithmetic processing unit 10 according to the program PGM stored in the storage unit 12 will be described. FIG. 5 is a flowchart showing an example of processing executed by the arithmetic processing unit 10. The arithmetic processing unit 10 executes the processing shown in FIG. 5 according to the program PGM, so that the chord information acquisition unit 20, the pitch information acquisition unit 22, the pronunciation content information acquisition unit 24, the singing voice output control unit 26, and the singing voice synthesis The unit 28 is realized.

  As shown in FIG. 5, the arithmetic processing unit 10 determines whether or not any key of the second keyboard is pressed based on the second performance operation data indicating the performance content of the second keyboard ( S100). When it is determined that any key of the second keyboard is depressed, the arithmetic processing unit 10 acquires a pitch corresponding to the depressed key (S102). The arithmetic processing unit 10 determines whether any chord is played on the first keyboard based on the first performance operation data indicating the performance content on the first keyboard (S104). That is, the arithmetic processing unit 10 determines whether or not a plurality of keys respectively corresponding to a plurality of sounds constituting the chord are pressed. The arithmetic processing unit 10 determines whether or not a chord used in the correspondence relationship data D (in other words, a chord associated with any phonetic character) is played. Ignore chords that are not used.

  When it is determined that a chord is being played on the first keyboard, the arithmetic processing unit 10 refers to the correspondence data D and acquires a pronunciation character associated with the chord (S106). And the arithmetic processing part 10 emits the singing voice of the phonetic character acquired by step S108 from the sound emission part 16 with the pitch acquired by step S104 (S108). For example, the arithmetic processing unit 10 reads out the waveform data of the speech unit corresponding to the phonetic character acquired in step S108 from the speech unit group G, and reads out the speech so as to be the pitch acquired in step S104. Pitch conversion is performed on the waveform data of the segment. And the arithmetic processing part 10 starts sound emission from the sound emission part 16 based on the waveform data after pitch conversion.

  After step S108 is executed, the arithmetic processing unit 10 monitors whether or not the key pressed on the second keyboard has been released (S110). When it is determined that the key pressed on the second keyboard has been released, the arithmetic processing unit 10 stops the sound emission started in step S108 (S112). And the arithmetic processing part 10 performs a process again from step S100. If it is not determined in step S100 that any key of the second keyboard is pressed, or if it is not determined in step S104 that any chord is played on the first keyboard. Also, the process is executed again from step S100.

  In the example shown in FIG. 5, it is determined whether any chord is being played on the first keyboard after determining that any key on the second keyboard is pressed (S104), Acquisition of pronunciation characters corresponding to the chord being played on the first keyboard is executed (S106). These determinations and acquisitions are based on the determination that any key on the second keyboard is pressed. It may be executed in advance before being executed.

  According to the singing voice output control apparatus 100 according to the first embodiment described above, the user can designate lyrics by playing chords. According to the singing voice output control device 100, the fingering for designating the lyrics becomes the fingering for playing the chord, and the fingering performed in the normal performance. It becomes easy to do. According to the singing voice output control apparatus 100, the user can easily specify both lyrics and pitches, and can easily generate singing voices having arbitrary lyrics and pitches. In addition, according to the singing voice output control apparatus 100, there is an advantage that even a user who is not accustomed to playing can wear fingering for playing chords by specifying lyrics.

  Although the case where Japanese lyrics are specified has been described above, the singing voice output control apparatus 100 can also specify lyrics in languages other than Japanese. For example, when it is possible to specify lyrics in a language other than Japanese, correspondence data D that associates chords with pronunciation characters (pronunciation symbols) in languages other than Japanese is used. That's fine. In the correspondence data D in this case, the phonetic characters (phonetic symbols) may be associated with chords in syllable units. That is, one syllable may be associated with one chord. For example, in the case of the English word “september”, the syllables “sep”, “tem”, and “ber” may be associated with chords.

Second Embodiment
A second embodiment of the present invention will be described below. In the correspondence data D of the first embodiment, chords and pronunciation characters are associated one-to-one. In the correspondence data D of the second embodiment, chords and pronunciation character strings are associated one-to-one. The block diagram of the singing voice output control device 100 according to the second embodiment is the same as that of the first embodiment. In the following description, components and functions that are different from those of the first embodiment will be mainly described, and detailed descriptions of components that have the same functions and operations as those of the first embodiment will be omitted.

  FIG. 6 shows an example of the correspondence data D stored in the storage unit 12 of the second embodiment. In the example shown in FIG. 6, one chord is associated with one phonetic character string (phonetic symbol string), and the phonetic character string (phonetic symbol string) and the chord are correlated one-to-one. Yes. Similar to the correspondence data D of the first embodiment, the correspondence data D of the second embodiment is data obtained by associating chord information with pronunciation content information indicating the content of pronunciation. In the example shown in FIG. 6, a pronunciation character string (a pronunciation symbol string) corresponds to the pronunciation content information. For example, in the example shown in FIG. 6, a pronunciation character string “Mabushi” meaning “dazzling” in Japanese is associated with a chord “Cm7”, and this pronunciation character string “Mabashi” is an example of pronunciation content information. It corresponds.

  In the example shown in FIG. 6, the pronunciation character string “Kei na Sora” meaning “beautiful sky” in Japanese is associated with the chord “C #”, meaning “dark sky” in Japanese. The pronunciation character string “Okusora” is associated with the chord “C # m”.

  That is, in the example shown in FIG. 6, the chord and the pronunciation character string are associated with each other so that the characteristics of the chord correspond to the contents of the pronunciation character string. Specifically, the chord and the pronunciation character string are associated with each other so that the impression that the chord gives to the listener corresponds to the impression that the content of the pronunciation character string gives to the listener. For example, a phonetic character string having a content that gives a bright impression to the listener is associated with a chord (for example, a chord of a major chord) that gives the listener a bright impression, and a phonetic character string having a content that gives a dark impression to the listener The chord is associated with a chord that gives the listener a dark impression (for example, a chord of a minor chord). Thus, the chord and the pronunciation character string are associated with each other, so that the user can guess the contents of the pronunciation character string associated with the chord.

  In the example shown in FIG. 6, Japanese pronunciation character strings are associated with chords, but for example, as shown in FIGS. 7 and 8, pronunciation character strings in languages other than Japanese are associated with chords. It may be. FIG. 7 shows an example of correspondence data D in which an English pronunciation character string (pronunciation content information) is associated with a chord, and FIG. 8 shows a German pronunciation character string (pronunciation content information) as a chord. An example of the correspondence data D associated with each other is shown. In singing voice synthesis using English or German, it is common to synthesize a singing voice by converting a word into a phonetic symbol. Therefore, in the correspondence data D shown in FIG. 7 and FIG. A sequence may be associated with a chord. In this case, the phonetic symbol string corresponds to the pronunciation content information.

  For example, in the example shown in FIG. 6, the user uses the first keyboard (first operation unit 30) to play chords in the order of “C7”, “C #”, “E”, “D # m7”. When the performance is performed, the pronunciation character strings respectively associated with these chords are designated as lyrics according to the order of the chords, and the singing voices of those pronunciation character strings are emitted in order from the sound emission unit 16. The That is, in this case, the singing voice of “Let's try it alone alone” is emitted from the sound emitting unit 16.

  Here, a performance operation performed for the user to specify lyrics in the second embodiment will be described with reference to FIG. FIG. 9 is a diagram for explaining an example of a performance operation performed by the user for designating lyrics. In FIG. 9, it is assumed that the pronunciation character string “Magai” meaning “dazzling” in Japanese is designated as the lyrics. In FIG. 9, the t-axis represents the time axis.

  As shown in FIG. 9, first, the user plays a chord “C7” associated with the pronunciation character string “Dazzle” using the first keyboard (first operation unit 30). Further, the user uses the second keyboard (second operation unit 32) to designate a pitch when the sound of the first character “ma” in the pronunciation character string is emitted. In the example shown in FIG. 9, the key “Fa” is pressed and “Fa” is designated.

  In this case, the pronunciation character string “Mabushii” associated with the chord “C7” is selected as the lyrics, the singing voice of the first character “MA”, and having the pitch of “Fa” The sound is synthesized and emitted from the sound emitting unit 16. Note that the sound continues to be emitted until the user releases the “Fa” key.

  After releasing the “Fa” key on the second keyboard, the user presses any key on the second keyboard to release the pitch of the second character “B”. Is specified. In the example shown in FIG. 9, since the key of “SO” is pressed, the singing voice of the second character “BU” and the pitch of “SO” is synthesized. Sound is emitted from the sound emitting unit 16.

  After releasing the “So” key on the second keyboard, the user presses any key on the second keyboard to obtain the pitch when outputting the third character “Shi”. specify. In the example shown in FIG. 9, since the key “La” is pressed, the singing voice of the third character “Shi” and the pitch of “La” is synthesized. Sound is emitted from the sound emitting unit 16.

  After releasing the “L” key on the second keyboard, the user presses any key on the second keyboard to obtain the pitch when the fourth character “I” is output. specify. In the example shown in FIG. 9, since the key of “shi” is pressed, the singing voice of the fourth character “i” and the pitch of “shi” is synthesized. Sound is emitted from the sound emitting unit 16.

  Next, the chord information acquisition unit 20, the pitch information acquisition unit 22, the pronunciation content information acquisition unit 24, the singing voice output control unit 26, and the singing voice synthesis unit 28 of the second embodiment will be described. However, since the chord information acquisition unit 20 and the pitch information acquisition unit 22 are the same as those in the first embodiment, detailed description thereof is omitted here.

  The pronunciation content information acquisition unit 24 refers to correspondence data D as shown in FIG. 6 (or FIGS. 7 and 8), for example, and generates a pronunciation character string associated with the chord information acquired by the chord information acquisition unit 20 ( Get pronunciation content information).

  The singing voice output control unit 26 outputs the singing voice of the pronunciation character string acquired by the pronunciation content information acquisition unit 24 from the sound emission unit 16 according to the pitch corresponding to the pitch information acquired by the pitch information acquisition unit 22. Let it sound. For example, the singing voice output control unit 26 emits the singing voice of each phonetic character included in the phonetic character string from the sound emitting unit 16 at a pitch specified by the user for each phonetic character. The singing voice output control unit 26 causes the singing voice synthesizing unit 28 to generate the singing voice as described above and emits the sound from the sound emitting unit 16.

  Next, an example of processing executed by the arithmetic processing unit 10 according to the second embodiment will be described. FIG. 10 is a flowchart illustrating an example of processing executed by the arithmetic processing unit 10 according to the second embodiment. When the arithmetic processing unit 10 executes the process shown in FIG. 10 according to the program PGM, the chord information acquisition unit 20, the pitch information acquisition unit 22, the pronunciation content information acquisition unit 24, and the singing voice output control unit 26 of the second embodiment. And the singing voice synthesis unit 28 are realized.

  As shown in FIG. 10, the arithmetic processing unit 10 determines whether or not any key of the second keyboard is pressed based on the second performance operation data indicating the performance content in the second keyboard ( S200). When it is determined that any key of the second keyboard is depressed, the arithmetic processing unit 10 acquires a pitch corresponding to the depressed key (S202). In addition, the arithmetic processing unit 10 determines whether any chord is played on the first keyboard based on the first performance operation data indicating the performance content on the first keyboard (S204). The processing in steps S200 to S204 is the same as that in steps S100 to S104 in FIG.

  When it is determined that a chord is being played on the first keyboard, the arithmetic processing unit 10 refers to the correspondence data D and acquires a pronunciation character string associated with the chord (S206). Then, the arithmetic processing unit 10 acquires the number N of characters of the pronunciation character string acquired in step S206 (S208). The arithmetic processing unit 10 initializes the variable i to 1 (S210).

  Next, the arithmetic processing unit 10 starts sound emission of the singing voice of the i-th character of the phonetic character string acquired in step S206 (S212). That is, the arithmetic processing unit 10 causes the sound emitting unit 16 to emit the singing voice of the i-th character of the pronunciation character string acquired in step S206 at the pitch acquired in step S202. For example, the arithmetic processing unit 10 reads the waveform data of the speech unit corresponding to the i-th character of the phonetic character string acquired in step S206 from the speech unit group G, and the pitch acquired in step S202. Thus, pitch conversion is performed on the waveform data of the read speech unit. Then, the arithmetic processing unit 10 emits the singing sound from the sound emitting unit 16 based on the waveform data after the pitch conversion.

  After step S212 is executed, the arithmetic processing unit 10 monitors whether or not the key pressed on the second keyboard has been released (S214). If it is determined that the key pressed on the second keyboard has been released, the arithmetic processing unit 10 stops the sound emission started in step S212 (S216).

  After step S216 is executed, the arithmetic processing unit 10 determines whether or not the variable i is less than N (S218). When it is determined that the variable i is less than N, the arithmetic processing unit 10 determines whether any key of the second keyboard is pressed based on the second performance operation data indicating the performance content of the second keyboard. It is determined whether or not (S220). When it is determined that any key of the second keyboard is depressed, the arithmetic processing unit 10 acquires a pitch corresponding to the depressed key (S222). And the arithmetic processing part 10 adds 1 to the variable i (S224), and performs step S212. That is, the arithmetic processing unit 10 starts sound emission of the singing voice of the i-th character in the pronunciation character string acquired in step S206 (S212). In this case, the arithmetic processing unit 10 causes the sound emitting unit 16 to emit the singing voice of the i-th character of the pronunciation character string acquired in step S206 at the pitch acquired in step S222. Thereafter, the arithmetic processing unit 10 executes the processing after step S214.

  The case where it is determined in step S218 that the variable i is not less than N is a case where sound emission of the singing voice of the pronunciation character string acquired in step S206 is completed. In this case, the arithmetic processing unit 10 executes the process again from step S200. If it is not determined in step S200 that any key of the second keyboard is pressed, or if it is not determined in step S204 that any chord is played on the first keyboard. In addition, the arithmetic processing unit 10 executes the processing again from step S200.

  In the example shown in FIG. 10, after determining that any key of the second keyboard is pressed, it is determined whether any chord is played on the first keyboard (S204), Acquisition of the pronunciation character string corresponding to the chord being played on the first keyboard (S206) was executed, but these determinations and acquisitions were made when any key on the second keyboard was pressed. It may be executed in advance before the determination.

  According to the singing voice output control apparatus 100 according to the second embodiment described above, the lyrics can be designated by the user playing a chord as in the first embodiment. Also, according to the singing voice output control device 100, the fingering for designating the lyrics becomes fingering for playing the chord and the fingering performed in a normal performance. Is easier to specify. In the second embodiment, since chords and pronunciation character strings are associated with each other, it is easier to specify lyrics compared to the first embodiment in which lyrics are specified one character at a time.

<Third Embodiment>
A third embodiment of the present invention will be described below. In the third embodiment, the pronunciation content information acquired by the pronunciation content information acquisition unit 24 for the same chord information is changed.

  FIG. 11 is a block diagram of the singing voice output control device 100 according to the third embodiment. As shown in FIG. 11, the third embodiment is different from the first embodiment and the second embodiment in that the correspondence changing unit 40 is included in the arithmetic processing unit 10. Note that components and functions that are different from those of the first and second embodiments will be mainly described, and detailed descriptions of components that have the same functions and operations as those of the first and second embodiments are omitted. .

  The correspondence change unit 40 changes the correspondence between the chord information and the pronunciation content information as time passes. That is, the correspondence changing unit 40 changes the pronunciation content information associated with the chord information as time elapses.

  For example, a plurality of correspondence data D is stored in the storage unit 12 of the third embodiment. The correspondence change unit 40 switches the correspondence data D referred to by the pronunciation content information acquisition unit 24 among the plurality of correspondence data D stored in the storage unit 12 as time elapses.

  For example, for each predetermined time (predetermined measure), the correspondence changing unit 40 selects any one of the plurality of correspondence data D stored in the storage unit 12. This selection may be performed randomly or according to a predetermined order. In this case, the pronunciation content information acquisition unit 24 refers to the correspondence data D selected by the correspondence change unit 40 and acquires the pronunciation content information. In this manner, in the third embodiment, the correspondence data D referred to by the pronunciation content information acquisition unit 24 changes with time.

  According to the singing voice output control device 100 according to the third embodiment described above, the lyrics of the singing voice are rich in change by changing the correspondence between chords and pronunciation content information over time. It becomes possible to.

  Note that the storage unit 12 may store time series data of pronunciation content information to be input by the user and time series data of chords to be played by the user. For example, model lyrics data (in other words, time-series data of pronunciation character strings (pronunciation content information) to be input by the user) and time-series data of chords to be performed by the user are stored in the storage unit 12. May be. Then, the correspondence changing unit 40 may change the correspondence data D based on these time series data.

  For example, in the above time-series data, a pronunciation character string Sx is defined as a pronunciation character string (pronunciation content information) to be input by a user at a certain timing Tx, and a chord Cx is a chord to be played by the user at the timing Tx. If so, the correspondence changing unit 40 changes the pronunciation character string (pronunciation content information) associated with the chord Cx to the pronunciation character string Sx shortly before the timing Tx arrives. For example, the correspondence relationship changing unit 40 uses the correspondence relationship data D referenced by the pronunciation content information acquisition unit 24 slightly before the timing Tx arrives, and the correspondence relationship data in which the pronunciation character string Sx is associated with the chord Cx. Change to D.

  Note that a plurality of correspondence data D may be stored as model lyric data in a format that can specify the switching order or switching timing. The correspondence change unit 40 may switch the correspondence data D referred to by the pronunciation content information acquisition unit 24 according to the switching order or the switching timing among the plurality of correspondence data D.

  In this aspect, for example, the name of the chord to be played by the user is displayed on the display unit 18 to guide the user. Or, for example, the user is guided to a key to be pressed (that is, a key corresponding to a chord to be played by the user). In this way, the user can designate exemplary lyrics by playing chords on the first keyboard according to the guidance.

<Fourth embodiment>
A fourth embodiment of the present invention will be described below. Similarly to the third embodiment, the pronunciation content information acquired by the pronunciation content information acquisition unit 24 for the same chord information is also changed in the fourth embodiment. However, the block diagram of the singing voice output control device 100 according to the fourth embodiment is the same as that of the first embodiment and the second embodiment. In the following description, components and functions that are different from those of the first and second embodiments will be mainly described, and detailed descriptions of components that have the same functions and operations as those of the first and second embodiments will be omitted. To do.

  In the correspondence data D of the fourth embodiment, chords and pronunciation content information are associated one-to-many. FIG. 12 shows an example of the correspondence data D of the fourth embodiment. In the correspondence data D shown in FIG. 12, a plurality of pronunciation character strings (pronunciation content information) are associated with one chord. Specifically, in the example shown in FIG. 12, three pronunciation character strings are associated with one chord. In the example shown in FIG. 12, a plurality of Japanese pronunciation character strings are associated with one chord. However, as in the examples shown in FIGS. A pronunciation character string (pronunciation content information) may be associated with one chord. Alternatively, a plurality of phonetic symbol strings (phonetic content information) in languages other than Japanese may be associated with one chord.

  The pronunciation content information acquisition unit 24 of the fourth embodiment, when a plurality of pronunciation content information is associated with the chord information acquired by the chord information acquisition unit 20, selects one of the plurality of pronunciation content information. select.

  For example, in the correspondence data D shown in FIG. 12, since a plurality of phonetic character strings are associated with one chord, a plurality of phonetic character strings are included in the chord information acquired by the chord information acquisition unit 20. It will be associated. In such a case, the pronunciation content information acquisition unit 24 selects any one of the plurality of pronunciation character strings. For example, the pronunciation content information acquisition unit 24 randomly selects one of a plurality of pronunciation character strings. Alternatively, the pronunciation content information acquisition unit 24 may select any one of the plurality of pronunciation character strings in accordance with a predetermined order. For example, when the first performance of the chord “C” is performed on the first keyboard, the pronunciation content information acquisition unit 24 selects the first of the plurality of pronunciation character strings associated with the chord “C”. When the second pronunciation character string is selected and the second performance of the chord “C” is performed on the first keyboard, the second pronunciation character string associated with the chord “C” is selected. The pronunciation character string may be selected. In this way, each time the chord “C” is played on the first keyboard, the pronunciation content information acquisition unit 24 determines in advance one of a plurality of pronunciation character strings associated with the chord “C”. You may make it select in order according to order.

  Also in the fourth embodiment, the processing as shown in FIG. 10 is executed. However, in the fourth embodiment, in step S <b> 206, the arithmetic processing unit 10 refers to the correspondence data D and selects and acquires one of a plurality of pronunciation character strings associated with the chord.

  According to the singing voice output control apparatus 100 according to the fourth embodiment described above, it is possible to make the lyrics of the singing voice rich in change as in the third embodiment.

  In the fourth embodiment, selection history data indicating a selection history of pronunciation content information may be stored in the storage unit 12. In addition, the pronunciation content information acquisition unit 24 selects one of the plurality of pronunciation content information as a selection history when a plurality of pronunciation content information is associated with the chord information acquired by the chord information acquisition unit 20. You may make it select based on data.

  FIG. 13 shows an example of selection history data. In the example shown in FIG. 13, a selection history of a pronunciation character string (pronunciation content information) is stored for each chord. For example, a selection history of the pronunciation character string associated with the chord “C” is stored in association with the chord “C”. In the example shown in FIG. 13, for example, the selection history “1, 3” indicates that the first pronunciation character string is selected and then the third pronunciation character string is selected.

  In this case, the pronunciation content information acquisition unit 24, when a plurality of pronunciation character strings (pronunciation content information) are associated with the chord information acquired by the chord information acquisition unit 20, among the plurality of pronunciation character strings. Either of them may be selected based on the selection history data shown in FIG.

  For example, the pronunciation content information acquisition unit 24 may preferentially select a pronunciation character string that has not been previously selected over a previously selected pronunciation character string. Specifically, the pronunciation content information acquisition unit 24 may select a pronunciation character string that has not been previously selected, and may not select a previously selected pronunciation character string. Alternatively, the pronunciation content information acquisition unit 24 sets the probability information so that the probability that a pronunciation character string that has not been selected last time is selected is higher than the probability that a pronunciation character string selected last time is selected. Thus, any one of the plurality of pronunciation character strings may be selected based on the probability information.

  Further, for example, the pronunciation content information acquisition unit 24 may select a pronunciation character string with a small number of selections more preferentially than a pronunciation character string with a large number of selections. Specifically, the pronunciation content information acquisition unit 24 may select a pronunciation character string with the smallest number of selections. Alternatively, the pronunciation content information acquisition unit 24 sets probability information so that a pronunciation character string having a smaller number of selections has a higher probability of being selected, and then selects one of the plurality of pronunciation character strings as probability information. You may make it select based on.

  In this way, it is difficult to repeatedly select the same pronunciation character string (pronunciation content information), so that the lyrics of the singing voice can be made more varied.

<Fifth Embodiment>
A fifth embodiment of the present invention will be described below. In the fifth embodiment, the user can register arbitrary lyrics (pronunciation content information) in the correspondence data D.

  FIG. 14 is a block diagram of the singing voice output control device 100 according to the fifth embodiment. As shown in FIG. 14, the fifth embodiment is different from the first to fourth embodiments in that a registration receiving unit 50 and a pronunciation content information registration unit 52 are included in the arithmetic processing unit 10. Hereinafter, functions and operations will be mainly described with respect to components that are different from those of the first to fourth embodiments, and detailed descriptions will be omitted with respect to components that have the same functions and operations as those of the first to fourth embodiments. .

  The registration accepting unit 50 accepts registration of new pronunciation content information. For example, the registration receiving unit 50 displays a screen for receiving an input of a pronunciation character string (pronunciation content information) on the display unit 18. In addition, the registration receiving unit 50 acquires the pronunciation character string input on the screen.

  The pronunciation content information registration unit 52 registers new pronunciation content information in the correspondence data D. The pronunciation content information registration unit 52 determines to which chord information the new pronunciation content information is associated. The pronunciation content information registration unit 52 determines the chord information associated with the new pronunciation content information based on the pronunciation content indicated by the new pronunciation content information.

  For example, when the new pronunciation character string (pronunciation content information) has bright content (in other words, when the content of the new pronunciation character string is a content that gives a bright impression to the listener), the pronunciation content information The registration unit 52 determines a chord that gives a bright impression to the listener (for example, a chord of a major chord) as a chord associated with the new pronunciation character string.

  For example, the storage unit 12 of the fifth embodiment stores a keyword group that gives a bright impression to the listener. The pronunciation content information registration unit 52 determines whether or not the keyword is included in a new pronunciation character string. If the keyword is included in the new pronunciation character string, the pronunciation content information registration unit 52 associates the new pronunciation character string with the chord corresponding to the keyword. That is, the pronunciation content information registration unit 52 determines that the new pronunciation character string has bright content, and adds the new pronunciation character string to a chord (for example, a chord of a major chord) that gives a bright impression to the listener. Associate.

  On the other hand, if the new pronunciation character string (pronunciation content information) has a dark content (in other words, the content of the new pronunciation character string is a content that gives a dark impression to the listener), the pronunciation content information The registration unit 52 determines a chord that gives a dark impression to the listener (for example, a chord of a minor chord) as a chord associated with the new pronunciation character string.

  For example, the storage unit 12 of the fifth embodiment stores a keyword group that gives a dark impression to the listener. The pronunciation content information registration unit 52 determines whether or not the keyword is included in a new pronunciation character string. If the keyword is included in the new pronunciation character string, the pronunciation content information registration unit 52 associates the new pronunciation character string with the chord corresponding to the keyword. That is, the pronunciation content information registration unit 52 determines that the new pronunciation character string has dark content, and adds the new pronunciation character string to a chord (for example, a chord of a minor chord) that gives a dark impression to the listener. Associate.

  According to the singing voice output control apparatus 100 according to the fifth embodiment described above, the user can register arbitrary lyrics (pronunciation content information) in the correspondence data D. Furthermore, according to the singing voice output control apparatus 100 according to the fifth embodiment, the lyrics are chords such that the lyrics input by the user correspond to the impression that the content gives to the listener and the impression that the chord gives to the listener. Are associated with each other, it is easy for the user to specify lyrics having desired contents (for example, lyrics having bright contents or lyrics having dark contents) among the lyrics inputted by the user.

<Modification>
The present invention is not limited to the first to fifth embodiments described above.

  (1) Correspondence relationship data D is not limited to the examples shown in FIGS. For example, in the correspondence data D shown in FIG. 2, phonetic characters and chords may be associated in consideration of the appearance frequency of characters and character chains (phoneme chains) in Japanese. Specifically, pronunciation characters that are frequently used may be associated with chords that are easy to play.

  Further, for example, a chord inversion may be associated with another pronunciation character or pronunciation character string. For example, in the correspondence data D shown in FIG. 2, the chord “C” is associated with the phonetic character “a”, but the first inverted form of the chord “C” is changed to another phonetic character (for example, “ka”). The second inverted form of the association and chord “C” may be associated with another pronunciation character (for example, “sa”).

  Further, for example, chords that are not used in the examples shown in FIGS. For example, since the chords “Cm” and “Cm7” may be difficult to distinguish depending on the user, other chords “Csus4”, “C-5”, or “Commit3” may be used. For example, in the correspondence data D shown in FIG. 2, the phonetic characters “A”, “I”, “U”, “E”, “O” are mixed with chords “C”, “Cm”, “Commit3”, “Csus4”, “C-5” may be associated with each other.

  (2) In the above, the case where the singing voice output control device 100 is realized by an electronic organ has been mainly described. However, the singing voice output control device 100 can also be realized by an electronic musical instrument other than the electronic organ.

  (2-1) For example, the singing voice output control device 100 can be realized by a keyboard instrument such as an electronic piano.

  If the keyboard instrument has only one keyboard, the chord playing operation to specify the pronunciation character or the pronunciation string and the pitch when the pronunciation character or the pronunciation string is emitted Both the performance operation for designating is performed using a single keyboard. In this case, for example, as shown in FIG. 15, one keyboard may be divided according to the sound range. In the example shown in FIG. 15, a key group (operator group) corresponding to a pitch range lower than a predetermined pitch (for example, C3) is set as a region for performing the former performance operation. On the other hand, a key group (operator group) corresponding to a range above a predetermined pitch (for example, C3) is set as an area for performing the latter performance operation. In this case, a key group corresponding to a range below a predetermined pitch (for example, C3) corresponds to the first operation unit 30 shown in FIG. 1 and the like, and a key group corresponding to a range above a predetermined pitch (for example, C3). Corresponds to the second operation unit 32 shown in FIG.

  (2-2) Also, for example, the singing voice output control device 100 can be realized by a stringed instrument such as an electronic guitar. For example, it can be realized by an electronic guitar compatible with the MIDI format.

  In this case, for example, a part of strings (operator group) is used for a chord playing operation for designating a pronunciation character or a pronunciation character string, and the remaining strings (operation group) are used as a pronunciation character or a pronunciation. What is necessary is just to use it for performance operation for designating the pitch at the time of emitting a character string. Specifically, for example, the first to fifth strings may be used for the former performance operation, and the sixth string may be used for the latter performance operation. In this case, the first to fifth strings correspond to the first operation unit 30 shown in FIG. 1 and the like, and the sixth string corresponds to the second operation unit 32 shown in FIG. 1 and the like.

  Alternatively, for example, the first to sixth strings of the neck portion may be used for the former performance operation, and the first to sixth strings of the body portion may be used for the latter performance operation. In this case, the first to sixth strings of the neck portion correspond to the first operation unit 30 shown in FIG. 1 and the like, and the first to sixth strings of the body portion correspond to the second operation unit 32 shown in FIG. Equivalent to. In this case, the pitch at which the phonetic character or the phonetic character string is emitted may be specified by the strength of playing the first to sixth strings.

  (2-3) For example, the singing voice output control apparatus 100 may be realized by a percussion instrument such as glocken, marimba, or xylophone. In this case, for example, the performance content may be acquired by installing a sensor.

  (3) The singing voice output control device 100 can also be realized by an information processing device connected to an electronic musical instrument via an interface. That is, the case where the arithmetic processing unit 10, the storage unit 12, the sound emitting unit 16, and the display unit 18 are incorporated in the electronic musical instrument has been described above. The display unit 18 may be provided in an information processing apparatus connected to an electronic musical instrument via an interface. In this case, performance operation data indicating a performance operation performed on the electronic musical instrument is supplied to the information processing apparatus via the interface, and the information processing apparatus executes processing based on the performance operation data.

  (4) The singing voice output control device 100 can also be realized by a single information processing device. That is, the arithmetic processing unit 10, the storage unit 12, the operation unit 14, the sound emitting unit 16, and the display unit 18 may be provided in the information processing apparatus.

  For example, the singing voice output control device 100 can be realized by an information processing device (a personal computer, a mobile phone, a portable information terminal, a game machine, or the like) provided with a touch panel. In this case, a performance operation may be received by displaying a virtual performance operator group on the touch panel.

  For example, two virtual keys may be displayed on the touch panel. In this case, as in the case of an electronic organ, one key is used for playing chords to specify pronunciation characters or pronunciation strings, and the other keyboard is used to emit pronunciation characters or pronunciation strings. You may make it use for the performance operation for designating the pitch of. In this case, the touch panel corresponds to the operation unit 14 shown in FIG. 1 and the like, and one key displayed on the touch panel (in other words, the part where one key in the touch panel is displayed) is shown in FIG. The other keyboard corresponding to the first operation unit 30 (in other words, the portion where the other keyboard is displayed in the touch panel) corresponds to the second operation unit 32 shown in FIG.

  For example, one virtual keyboard may be displayed on the touch panel, or a plurality of virtual strings may be displayed on the touch panel.

  (5) All or part of the data (speech segment group G or correspondence data D) stored in the storage unit 12 is stored in another device that can communicate with the singing voice output control device 100 via a communication network. May be.

  (6) The singing voice synthesizing unit 28 and the sound emitting unit 16 are connected to a device including a chord information acquiring unit 20, a pitch information acquiring unit 22, a pronunciation content information acquiring unit 24, and a singing voice output control unit 26 via a communication network. It may be provided in other devices that can communicate with each other. That is, the singing voice output control unit 26 may cause the singing voice synthesizing unit 28 to generate a singing voice and emit the sound from the sound emitting unit 16 via the communication network.
