<A: First Embodiment>
FIG. 1 is a block diagram of a sound processing apparatus 100 according to the first embodiment of the present invention. The sound processing device 100 is a speech synthesizer that generates a sound such as a singing sound (hereinafter referred to as “synthetic sound”) in which a plurality of designated sounds are arranged in time series. As shown in FIG. This is realized by a computer system including a storage device 12, an input device 14, a display device 16, and a sound emitting device 18.

  The arithmetic processing unit (CPU) 10 executes a plurality of functions (acoustic generation unit 22, display control unit 24, information management unit 26) necessary for generating the acoustic signal SOUT by executing the program PG stored in the storage device 12. Realize. The acoustic signal SOUT is a signal indicating a waveform of the synthesized sound on the time axis. A configuration in which each function of the arithmetic processing device 10 is realized by a dedicated electronic circuit (DSP), or a configuration in which each function of the arithmetic processing device 10 is distributed over a plurality of integrated circuits may be employed.

  The input device 14 is a device (for example, a mouse or a keyboard) that receives an instruction from a user. The display device 16 (for example, a liquid crystal display device) displays an image instructed from the arithmetic processing device 10. The sound emitting device 18 (for example, a speaker or headphones) reproduces a synthesized sound corresponding to the acoustic signal SOUT generated by the arithmetic processing device 10.

  The storage device 12 stores a program PG executed by the arithmetic processing device 10 and various data (segment group DV, score information DS) used by the arithmetic processing device 10. A known recording medium such as a semiconductor recording medium or a magnetic recording medium or a combination of a plurality of types of recording media is arbitrarily employed as the storage device 12. A configuration in which the program PG and each data (DV, DS) are distributed and stored in a plurality of recording media may be employed.

  The unit group DV is a set (library) of a large number of unit data d corresponding to different speech units. The segment data d is data indicating the waveform and feature amount of the speech segment, and is used as a material for synthesized sound. The phoneme segment is a phoneme which is the smallest unit that can be distinguished auditorily or a phoneme chain in which a plurality of phonemes are connected. A plurality of segment data d corresponding to different attributes (hereinafter referred to as “segment attributes”) is prepared for each speech segment. In the present embodiment, the pitch and volume of the speech unit and the speaker are exemplified as the unit attributes. That is, the segment data d is stored in the storage device 12 for each combination (segment attribute) of pitch, volume, and speaker.

  The musical score information DS is information (score data) for designating a designated sound in time series, and is composed of a plurality of unit information U corresponding to different designated sounds as shown in FIG. Each unit information U includes note information UN, character information UL, and one or more piece information UV. The note information UN is information for designating the note of the designated sound, and includes the start point, duration and pitch of the designated sound. The character information UL is information that specifies the content of pronunciation of the designated sound, and includes a pronunciation character (lyric syllable) and a phonetic symbol (phonetic). A phonetic symbol (for example, a SAMPA (Speech Assessment Methods Phonetic Alphabet) symbol) is automatically set according to a phonetic character. The unit information UV is information for specifying the unit data d used for the synthesis of the designated sound. For each speech unit necessary for the synthesis of the designated sound, the unit identifier and the unit attribute (pitch, volume, Speaker). The unit identifier is a code (unit name) for identifying a speech unit. The symbol “Sil” in FIG. 2 means silence.

  As described above, the musical score information DS includes a plurality of types of control information (start point, continuation length, pitch, phonetic character, phonetic symbol, segment identifier, segment attribute) that define the specified sound for each specified sound. Are arranged in time series. As can be understood from FIG. 2, the score information DS can also be grasped as a set of a time series of a plurality of note information UN, a time series of a plurality of character information UL, and a time series of a plurality of segment information UV.

  When the user instructs the generation of the synthesized sound by operating the input device 14, the sound generation unit 22 in FIG. 1 uses the segment group DV and the score information DS stored in the storage device 12 to generate the sound of each designated sound. A signal SOUT is generated. Specifically, the sound generation unit 22 adjusts the segment data d corresponding to the segment identifier and the segment attribute of the score information DS in the segment group DV to the duration and pitch defined by the note information UN. Then, the adjusted segment data d is arranged at the start point defined by the note information UN and then connected to each other to generate (synthesize speech) the acoustic signal SOUT. The sound signal SOUT generated by the sound generation unit 22 is supplied to the sound emitting device 18 and reproduced as sound.

  The display control unit 24 shown in FIG. 1 generates the score image 40 shown in FIG. 3 and the editing chart 50 shown in FIG. 4 which are visually recognized by the user for generating and editing the score information DS and displaying them on the display device 16. As shown in FIG. 3, the score image 40 is an image that presents the temporal change in the pitch of each designated sound within a region in which the pitch axis (vertical axis) and the time axis (horizontal axis) are set. Piano roll image). Specifically, the sound indicator 42 in which the designated sound is made into a graphic is arranged in the score image 40 in time series. The display control unit 24 variably sets the position of the pitch indicator 42 in the direction of the pitch axis according to the pitch specified by the note information UN, and the sound indicator 42 according to the start point specified by the note information UN. The position in the direction of the time axis is set to be variable. The size of the sound indicator 42 in the direction of the time axis is variably set according to the duration of the note information UN. In addition, pronunciation characters (lyrics) and phonetic symbols specified by the character information UL are arranged on the sound indicator 42.

  The section where the sound indicator 42 is arranged in the musical score image 40 in the time series of the designated sound defined by the musical score information DS is changed (scrolled) in accordance with an instruction from the user to the input device 14. The user can select and edit one sound indicator 42 (designated sound) from the score image 40 by appropriately operating the input device 14. The display control unit 24 sets the sound indicator 42 of the designated sound selected by the user (the sound indicator 42 of the pronunciation character “sa” in FIG. 3) different from the other sound indicators 42 (color and gradation). ).

  The editing chart 50 is an image that presents the score information DS stored in the storage device 12 to the user in a tabular form, and is arranged in a matrix in the X and Y directions orthogonal to each other as shown in FIG. The plurality of unit regions 52 (cells) are configured. Control information (start point, duration, pitch, phonetic character, phonetic symbol, segment identifier, segment attribute) included in the score information DS is arranged in each unit area 52. That is, in the score image 40, the control information of the note information UN and the character information UL of the designated sound is schematically displayed as a figure, whereas in the editing chart 50, each control of the score information DS including the segment information UV. Information is displayed in detail as specific numerical values and characters. The user can select a desired unit area 52 and change the control information in the unit area 52.

  A set of a plurality of unit areas 52 arranged in the X direction (hereinafter referred to as “row area 54”) corresponds to one specified sound (one unit information U in the score information DS) specified by the score information DS. . A plurality of types of control information corresponding to one designated sound in the score information DS are arranged in each unit area 52 (for one line of the editing chart 50) in the row area 54 corresponding to the designated sound. In each unit area 52 (one column of the editing chart 50) arranged in the Y direction, the same type of control information of each designated sound is arranged in time series.

  The display control unit 24 includes a predetermined number of designated sounds including a designated sound selected by the user in the musical score image 40 in the time series of the designated sounds defined by the score information DS (for example, the selected designated sound and the predetermined number before and after the selected sound). A row area 54 corresponding to each of the designated sounds) is arranged in the editing chart 50. For example, a configuration in which a line area 54 is set in the editing chart 50 for each designated sound in the section being displayed in the score image 40, or an editing chart for each designated sound over a wider range than the section being displayed in the score image 40. A configuration in which the row area 54 is set to 50 may be employed. The display control unit 24 selects a line area 54 corresponding to the designated sound of one sound indicator 42 selected by the user from the musical score image 40 in the editing chart 50 (in FIG. 4, the line corresponding to the phonetic character “sa”). The area 54) is displayed in a mode (color or gradation) different from the other row areas 54. Therefore, there is an advantage that the user can easily confirm the correspondence between each sound indicator 42 in the score image 40 and each row area 54 in the editing chart 50.

  The information management unit 26 updates the score information DS at any time in accordance with an instruction from the user with respect to the score image 40 and the editing chart 50. The display control unit 24 matches the contents of both images by updating the score image 40 and the editing chart 50 as needed so that the change of the score information DS by the information management unit 26 is reflected. Specific operations of the information management unit 26 and the display control unit 24 relating to the update of the musical score information DS will be exemplified below.

  The user can instruct editing (addition, change, deletion) of each sound indicator 42 in the musical score image 40 by appropriately operating the input device 14. For example, when the user instructs addition of the sound indicator 42, the display control unit 24 adds the sound indicator 42 instructed by the user to the score image 40, and the information management unit 26 sends the sound indicator 42 to the sound indicator 42. The corresponding unit information U of the designated sound is added to the score information DS. The display control unit 24 adds to the editing chart 50 a row area 54 in which the control information of the unit information U added to the score information DS is arranged in the unit area 52.

  When the user instructs to change the selected sound indicator 42, the display control unit 24 changes the position and size of the sound indicator 42 according to the instruction from the user, and the information management unit 26 displays the score. In the information DS, the unit information U of the designated sound corresponding to the sound indicator 42 is changed according to the change of the sound indicator 42. The display control unit 24 updates each control information in the editing chart 50 so as to be consistent with the change of the unit information U.

  When the user instructs the deletion of the selected sound indicator 42, the display control unit 24 deletes the sound indicator 42 from the score image 40, and the information management unit 26 designates the designation corresponding to the sound indicator 42. The sound unit information U is deleted from the score information DS. The display control unit 24 deletes the row area 54 corresponding to the unit information U deleted from the score information DS from the editing chart 50.

  In addition to the instruction for editing the musical score image 40 described above, the user instructs to edit (add, change, delete) the control information in the desired unit area 52 of the editing chart 50 by operating the input device 14. Is possible. A specific procedure for editing each control information will be described below by dividing each control information of the note information UN and the character information UL and editing each control information of the segment information UV.

[A] Editing control information of note information UN and character information UL
There are a fixed mode and a floating mode as operation modes applied to the editing of the note information UN and the character information UL. In fixed mode, the position on the time axis of control information other than the object to be edited is maintained before and after editing. In floating mode, the position on the time axis of subsequent control information moves in conjunction with the addition or editing of control information. (Down / up). The information management unit 26 variably selects an operation mode in accordance with an instruction from the user to the input device 14.

  In the following description, the operations in the fixed mode and the floating mode are illustrated for each of the case where the addition of control information is instructed and the case where the deletion of existing control information is instructed. 5 and 6 referred to in the following description, for the sake of convenience, editing of pronunciation characters among a plurality of types of control information is illustrated for convenience. Editing of control information other than pronunciation characters is also executed in the same procedure.

[A1] When control information addition is instructed
The user can instruct addition of desired control information to the editing chart 50 by appropriately operating the input device 14. For example, control information directly input by the user by operating the input device 14 can be added to the editing chart 50. Further, existing control information corresponding to one or more unit areas 52 selected by the user from the editing chart 50 can be added to other unit areas 52 of the editing chart 50. The addition of the existing control information in the editing chart 50 includes duplication (copy and paste) and movement (cut and paste) of the control information in the editing chart 50. The user can select the control information of the unit area 52 over a plurality of lines (that is, a plurality of designated sounds) of the editing chart 50 as a target of duplication or movement.

  When the addition of the control information is instructed in the fixed mode, the information management unit 26 instructs the addition of the control information of the unit area 52 selected by the user in the editing chart 50 in the score information DS. Replace (overwrite) with control information. The display control unit 24 updates the editing chart 50 so that the change of the score information DS by the information management unit 26 is reflected. For example, when the user designates “Asa” and gives an instruction to add “Hirumo” in the situation where the pronunciation character “Asakura” exists as shown in part (A) of FIG. 5, the display control unit 24, “Asa” is replaced with “Hirumo” as shown in part (B) of FIG. Further, the display control unit 24 updates the score image 40 so as to correspond to the change of the score information DS (change of the editing chart 50).

  On the other hand, when addition of control information is instructed in the floating mode, the information management unit 26 instructs the addition to the position of the unit area 52 selected from the editing chart 50 by the user in the score information DS. Control information is inserted, and the subsequent control information is decremented by the amount of control information added this time. The display control unit 24 updates the editing chart 50 so that the change of the score information DS by the information management unit 26 is reflected. For example, in the situation of part (A) in FIG. 5, when the user designates “Asa” and instructs to add “hiruga”, the display control unit 24 is as shown in part (C) of FIG. 5. In addition, “Hirumo” is inserted immediately after “Asa” and the existing “Kuru” is moved down immediately after “Hiruga”. Further, the display control unit 24 updates the score image 40 so as to correspond to the change of the score information DS (change of the editing chart 50).

  As described above, when control information is added in the floating mode, subsequent control information is deferred, and therefore unit information U that does not include control information other than the deferred control information may be generated. For example, FIG. 4 exemplifies a case where the unit information U of the designated sound of the pronunciation character “Kuru”, which is deferred by the addition of the pronunciation character in the floating mode, does not include the note information UN and the unit information UV. When a phonetic character is added in the procedure exemplified above (fixed mode, floating mode), the information management unit 26 specifies a phonetic symbol corresponding to each phonetic character and sets it in the character information UL.

[A2] When control information deletion is instructed
When the deletion of the control information is instructed in the fixed mode, the information management unit 26 changes the control information of the unit area 52 selected as the deletion target in the editing chart 50 among the score information DS to the initial value. . The display control unit 24 updates the editing chart 50 so that the change of the score information DS by the information management unit 26 is reflected. For example, when the user instructs to delete “Asa” in the situation where the pronunciation character “Asakura” exists as shown in part (A) of FIG. 6, the display control unit 24 displays the part (FIG. As shown in B), each pronunciation character of “Asa” is replaced with an initial value “A”. Further, the display control unit 24 updates the score image 40 so as to correspond to the change of the editing chart 50 (score information DS).

  On the other hand, when deletion of the control information is instructed in the floating mode, the information management unit 26 deletes the control information instructed by the user from the score information DS and advances the subsequent control information by the current deletion. . The display control unit 24 updates the editing chart 50 so that the change of the score information DS by the information management unit 26 is reflected. For example, in the situation of part (A) in FIG. 6, when the user instructs deletion of “Asa”, the display control unit 24 deletes “Asa” as shown in part (C) of FIG. And the subsequent “coming” is advanced. Further, the display control unit 24 updates the score image 40 so as to correspond to the change of the editing chart 50 (score information DS).

[B] Editing each piece of control information (segment attribute) of the segment information UV
When the user selects a unit area 52 corresponding to the segment attribute (pitch, volume, speaker) of the segment information UV in the editing chart 50, the display control unit 24, as illustrated in FIG. Then, a list 56 in which a plurality of choices of segment attributes are arranged is displayed in the vicinity of the unit area 52 (the “volume” unit area 52 in FIG. 7) selected by the user. The element attributes of the element data d actually included in the element group DV are arranged in the list 56 as options. The user can select any of a plurality of options from the list 56 by operating the input device 14. The information management unit 26 changes the segment attribute corresponding to the unit area 52 selected by the user in the score information DS to the content of the option selected from the list 56 by the user. The display control unit 24 updates the segment attribute in the editing chart 50 so that the change of the score information DS by the information management unit 26 is reflected.

  As described above, in the present embodiment, each control information included in the score information DS is displayed in a tabular format as the editing chart 50 and is updated according to an instruction from the user. Therefore, the user can edit while confirming the detailed contents of the score information DS efficiently. Further, by visually recognizing the musical score image 40 displayed together with the editing chart 50, there is an advantage that the user can intuitively grasp the outline of the time series of the designated sound.

  Further, since the control information over the plurality of unit areas 52 of the editing chart 50 is collectively copied or moved, the control information of each designated sound is individually edited by an instruction to each sound indicator 42 of the score image 40. There is also an advantage that the musical score information DS can be edited efficiently compared to the case.

<B: Second Embodiment>
Next, a second embodiment of the present invention will be described. In addition, about the element which an effect | action and function are equivalent to 1st Embodiment in each following illustration, the code | symbol referred by the above description is diverted and each detailed description is abbreviate | omitted suitably.

  FIG. 8 is a schematic diagram of the editing chart 50 in the second embodiment. As understood from FIG. 8, the character information UL in the musical score information DS of the second embodiment includes voice management information in addition to phonetic characters and phonetic symbols similar to those of the first embodiment. The voice management information is control information for designating permission / prohibition of changing the voice symbol. As shown in FIG. 8, the editing chart 50 is configured to include a unit area 52 in which voice management information is arranged for each designated sound (for each row area 54). In the example of FIG. 8, the voice management information that specifies prohibition of changing the voice symbol is expressed by the symbol “v”. The voice management information for designating permission to change the voice symbol is blank.

  When addition of pronunciation characters (control information) is instructed in the fixed mode, the information management unit 26 replaces the existing pronunciation characters in the unit area 52 selected by the user in the editing chart 50 with additional control information (above The phonetic symbol corresponding to each phonetic character is updated to the phonetic symbol corresponding to the character information after replacement. However, for the designated sound that the voice management information designates prohibition, the voice symbol is maintained as it was before editing even when the pronunciation character is changed.

  For example, as shown in part (A) of FIG. 9, the voice management information of the designated sound of “ru” among the pronunciation characters “Asa Hiruga” designates prohibition (symbol v), and the sound of the other designated sound. Assume that the management information specifies permission. As shown in part (A) of FIG. 9, when the user selects the pronunciation character “Asa” in the fixed mode and gives an instruction to add (duplicate) to the position of “Hiruga”, the information management unit 26 As shown in part (B) of FIG. 9, “Hiruga” in the musical score information DS is replaced with “Asa”, and the voice symbol “ci” of “Hi” before the replacement is replaced with the voice of “A” after the replacement. Update to symbol “a”. The phonetic symbol "ga" does not change, so the phonetic symbol is not updated. On the other hand, since the voice management information designates prohibition for “RU” before replacement, the information management unit 26 replaces “RU” in part (A) of FIG. 9 with “SA” in part (B). Nevertheless, the phonetic symbol is maintained at the “RU” phonetic symbol “4M” before the replacement (shaded portion). The display control unit 24 updates the score image 40 and the editing chart 50 so that the change in the score information DS is reflected.

  Although FIG. 9 illustrates the case where the user selects only the pronunciation character “Asa”, as shown in the part (A) of FIG. 10, both the pronunciation character and the phonetic symbol of “Asa” are used by the user. Is selected and the addition is instructed, the information management unit 26 selects “Hiruga” as shown in part (B) of FIG. 10 regardless of the content of the voice management information of “Hiruga” as the paste destination. Phonetic characters, phonetic symbols, and voice management information are changed to phonetic characters, phonetic symbols, and voice management information of “Asa”. That is, the phonetic symbol “ci” of “hi” is replaced with the phonetic symbol “a” of “a”, and the phonetic symbol “4M” of “ru” is replaced with the phonetic symbol “sa” of “sa”.

  The contents of the voice management information in the score information DS are changed from one of permission and prohibition to change the phonetic symbol to the other in accordance with an instruction from the user to the editing chart 50. For example, the user can individually select each unit area 52 of the editing chart 50 to change the sound management information, or can simultaneously select a plurality of unit areas 52 (columns) of the editing chart 50 to select a plurality of unit areas 52. It is possible to instruct an operation for collectively changing the sound management information of the designated sound. When the voice management information is changed from prohibition to permission, the voice symbol of the designated sound is updated to the content corresponding to the pronunciation character. For example, when the voice management information (speech management information of the second pronunciation character “sa”) that is designated as prohibited in the state of part (B) in FIG. The phonetic symbol “4M” is automatically updated to the original phonetic symbol “sa” corresponding to the phonetic character “sa”.

  In the second embodiment described above, the same effect as that of the first embodiment is realized. In the second embodiment, a pronunciation character is used for the designated sound whose voice management information designates prohibition of the change of the phonetic symbol. Since the phonetic symbols are maintained even when changed, there is an advantage that the musical score information DS can be edited with the desired phonetic symbols fixed.

<C: Third Embodiment>
FIG. 11 is a schematic diagram of the editing chart 50 in the third embodiment. As understood from FIG. 11, the segment information UV in the score information DS of the third embodiment is added to the segment identifier and segment attributes (pitch, volume, speaker) similar to those of the first embodiment. And includes waveform management information. The waveform management information is control information for designating display / non-display of the waveform of the speech unit. As shown in FIG. 11, the editing chart 50 is configured to include a unit area 52 in which waveform management information is arranged for each piece information UV. In the example of FIG. 11, the waveform management information for designating the display of the speech unit waveform is represented by the symbol “v” (the non-displayed waveform management information is blank).

  The content of the waveform management information is changed from one of display and non-display to the other in accordance with an instruction from the user to the editing chart 50. For example, the user can individually select each unit region 52 of the editing chart 50 to change the waveform management information, or can simultaneously select a plurality of unit areas 52 (columns) of the editing chart 50 to select a plurality of unit areas 52. It is possible to instruct an operation for collectively changing the waveform management information of the designated sound.

  The display control unit 24 causes the display device 16 to display the waveform image 60 of FIG. 12 in addition to the score image 40 and the editing chart 50 similar to those in the first embodiment. As shown in FIG. 12, the waveform image 60 is an image in which the waveform 62 indicated by the segment data d of the speech unit is arranged for each speech unit that the waveform management information of the unit information UV designates display. . FIG. 12 illustrates a case where the waveforms 62 of three speech elements (Sil-a, a-s, sa) whose waveform management information designates display are arranged in parallel on the waveform image 60.

  The information management unit 26 adjusts the speech unit waveform 62 (segment data d) in accordance with an instruction from the user to the waveform image 60. For example, the information management unit 26 uses a range used for synthesizing a specified sound in the waveform 62 of the speech unit (for example, a reference range used for normal synthesis, a maximum range used for synthesizing a long sound, The minimum range used at the time of synthesis), the change in volume of the speech unit (envelope on the time axis), and the range that overlaps the previous and next speech units in the speech unit waveform 62 are used for the input device 14. It is variably set according to instructions from the person. The sound generation unit 22 generates the sound signal SOUT using the segment data d after the waveform adjustment by the information management unit 26.

  In the third embodiment described above, the same effects as in the first embodiment are realized. In the third embodiment, the waveform 62 of the speech unit specified by the display management information is displayed on the display device 16 and edited in accordance with an instruction from the user. While confirming in detail the waveform 62 of the speech unit actually used for synthesis, it is possible to efficiently adjust it to its desired characteristics. Note that the second embodiment using voice management information and the third embodiment using waveform management information may be merged.

  Note that the control information (control information displayed in the editing chart 50) constituting the score information DS is exemplified in the above-described forms (designated sound start point, duration, pitch, phonetic character, phonetic symbol, (Voice management information, segment identifier, segment attribute, waveform management information). The musical score information DS applied to the present invention is included as information in which a plurality of types of control information including information applied to the synthesis of the designated sound are arranged in time series.

  Further, the form of the editing chart 50 is not limited to the illustration in each of the above forms. For example, an editing chart 50 in which each control information is arranged with the X direction (horizontal direction) as a time axis may be employed. In addition, the sound generation unit 22 is omitted in the sound processing apparatus 100 (information editing apparatus) for editing the score information DS.
