1. Configuration FIG. 1 is a diagram illustrating a schematic configuration of a speech synthesizer 1 according to an embodiment of the invention. The voice synthesizer 1 is a device that synthesizes a singing voice in real time. The speech synthesizer 1 includes an input device 10 and a song synthesis control device 20. In order to synthesize a singing voice, at least information on lyrics and pitch is required. In this example, lyrics are input at the input device 10, and pitches are input at the singing synthesis control device 20. In order to transmit lyrics input by the input device 10, the input device 10 and the singing voice synthesis control device 20 are connected using a cable 30 for transmitting and receiving information. However, the input device 10 and the song synthesis control device 20 may be connected wirelessly instead of wired.

  The song synthesis control device 20 is a device that performs song synthesis. In this example, the singing synthesis control device 20 has an external appearance imitating a keyboard instrument exemplified by an electronic piano. The singing synthesis control device 20 includes an operation unit 21 on the front surface. The operation unit 21 includes a plurality of operation elements 211 imitating keys. The singing voice synthesis control device 20 controls the synthesis of the singing voice based on the lyrics input from the input device 10 and the pitch determined according to the operation of pressing any one of the operators 211.

  The input device 10 is a device for inputting lyrics. The lyrics are composed of a combination of vowels and consonants. The input device 10 has a rod shape. The input device 10 includes a gripped part 11 and a light emitting part 12. The gripped part 11 is a part gripped by the user. The light emitting unit 12 is a part that emits light. As described above, the input device 10 also functions as a lighting fixture exemplified by chemical lights. A well-known technique is used for the light emission part 12 and its control.

  FIG. 2 is a diagram illustrating the configuration of the gripped portion 11. The gripped portion 11 has a contact surface 11A that comes into contact with the user's finger in the use state. A plurality of switches 111 to 116 are provided on the contact surface 11A. The switch provided on the contact surface 11A is, for example, a momentary push switch. According to this switch, ON is input while these switches are pressed, and OFF is input while the switches are not pressed. The switch may not be a push type as long as an on / off input is possible.

  In this embodiment, the vowels of the vowels and consonants constituting the lyrics are designated by the operation of the switches 111 to 114. For example, while only the switch 111 is pressed, [a] (A) is designated. While only the switch 112 is being pressed, [i] (yes) is designated. [U] (U) is designated while only the switch 113 is pressed. While only the switches 111 and 112 are pressed, [e] (e) is designated. While only the switches 111 and 113 are pressed, [o] (O) is designated.

  While the switch 114 is being pressed, use of stuttering (semi-vowel) is designated. For example, the roar of [ka] (ka) is [kja] (kya). For this reason, while the switch 114 is pressed, it is designated to insert the semi-vowel [j] immediately before the vowel [a] in order to express the stuttering.

  The consonant of the vowel and consonant of the lyrics is designated by the operation of the switches 115 and 116 and the movement of the input device 10. In this example, the “movement” of the input device 10 is a change (that is, movement) of the position of the input device 10 due to the input device 10 being shaken.

  In this embodiment, clear sound is designated by the movement of the input device 10, whether or not muddy sound is used is designated by operating the switch 115, and whether or not semi-voiced sound is used is designated by operating the switch 116. For example, when [k] (or line) is designated as a consonant and use of muddy sound is designated, [g] (ga line) is designated. [H] (ha line) is specified as a consonant, and [p] (pa line) is specified when use of a semi-turbid sound is specified.

  FIG. 3 is a diagram illustrating the relationship between the movement of the input device 10 and the specified consonant. Here, the central axis extending from the bottom to the top of the input device 10 is defined as “L”. [K] is designated while the input device 10 is swung in the axial direction of the central axis L, and [h] is designated while the input device 10 is swung in the opposite direction. While the input device 10 is swung in the direction rotated 45 degrees clockwise with respect to the central axis L, [s] (running) is swung in the opposite direction, while [m] (Line) is specified. While the input device 10 is swung in the direction rotated 90 degrees clockwise with respect to the central axis L, [t] (the row) is swung in the opposite direction, [y] (Or line) is specified. While the input device 10 is swung in a direction rotated 135 degrees clockwise with respect to the central axis L, [n] (a row) is swung in the opposite direction, [r] (Ra line) is specified. When the input device 10 is not swung in any direction, [a] (row) is designated. When the input device 10 is swung in a direction other than the direction indicated by the arrow shown in FIG. 3, the consonant corresponding to the closest direction is designated.

  The relationship between the movement of the input device 10 and the designated consonant is not limited to the example of FIG. In the example of FIG. 3, when the input device 10 is used while standing perpendicular to the ground, a consonant is defined according to the movement of the input device 10 in a plane substantially perpendicular to the ground. However, the central axis L in the example of FIG. 3 may be set laterally in the input device 10 (specifically, for example, a direction perpendicular to the surface of the gripped portion 11 where the switch is provided). According to this example, consonants are defined according to the movement of the input device 10 on a surface substantially horizontal to the ground.

  Note that the sounds [wa], [o], and [n] are specified by turning on the switch 115 and not moving the input device 10, for example. In addition, when expressing small characters such as [］], [］] [［], a switch for designating this may be provided separately.

  FIG. 4 is a diagram illustrating a functional configuration of the input device 10 and the song synthesis control device 20. The input device 10 includes an operation detection unit 101, a first specification unit 102, a motion detection unit 103, a second specification unit 104, and a transmission unit 105.

The first designation unit 102 designates a vowel of the vowels and consonants of the lyrics according to the operation state of the switches 111 to 114 detected by the operation detection unit 101. The motion detection unit 103 detects the motion of the input device 10. In this embodiment, the motion detection unit 103 detects at least the direction in which the input device 10 has been moved (the direction in which the input device 10 has been shaken) based on information from a sensor (not shown). The sensor includes, for example, a biaxial or triaxial acceleration sensor. The motion detection unit 103 detects the motion of the input device 10 based on, for example, the acceleration measured by the acceleration sensor, the speed obtained from the acceleration, and the magnitude of the displacement. The motion detection unit 103 may detect the motion of the input device 10 using a sensor other than the acceleration sensor. The second designation unit 104 converts the consonant of the vowels and consonants of the lyrics into the movement of the input device 10 detected by the movement detection unit 103 and the operation state of the switches 115 and 116 detected by the operation detection unit 101. Specify accordingly. The transmitting unit 105 transmits the vowel specified by the first specifying unit 102 and the consonant specified by the second specifying unit 104 to the singing synthesis control device 20.

  Each function of the input device 10 is equipped with an arithmetic processing unit exemplified by a CPU (Central Processing Unit), a memory exemplified by a ROM (Read only memory) and a RAM (Random access memory), and a communication module. Implemented by the processor. Each function of the input device 10 is implemented by, for example, a processor and a program executed by the processor. The function of the input device 10 may be implemented by two or more processors or programs.

The singing voice synthesis control device 20 includes a receiving unit 201, an operation detection unit 202, a determination unit 203, a synthesis instruction unit 204, a voice synthesis unit 205, and a voice output unit 206. The receiving unit 201 receives lyrics vowels and consonants from the input device 10 (transmitting unit 105). The operation detection unit 202 is based on a signal input from each operator 211 of the operation unit 21.
The state of operation of each operator 211 is detected. Based on the detection result of the operation detection unit 202, the determination unit 203 determines a pitch according to the operation element 211 pressed by the user. The synthesis instruction unit 204 instructs the speech synthesis unit 205 to synthesize the singing voice based on the consonant and vowel received by the reception unit 201 and the pitch determined by the determination unit 203. The voice synthesizer 205 synthesizes a singing voice in accordance with a synthesis instruction from the synthesis instruction unit 204 to generate a singing voice (synthesized voice). The voice synthesis unit 205 outputs a sound signal indicating the synthesized singing voice to the voice output unit 206. The sound output unit 206 outputs sound according to the sound signal output from the sound synthesis unit 205.

  Note that each function of the receiving unit 201, the operation detecting unit 202, the determining unit 203, the synthesis instructing unit 204, and the voice synthesizing unit 205 includes an arithmetic processing unit exemplified by a CPU, a memory exemplified by a ROM and a RAM, and a communication module. Etc. are mounted by a processor equipped with. Each function of the song synthesis control device 20 is implemented by, for example, a processor and a program executed by the processor. Moreover, the function of the song synthesis control apparatus 20 may be implemented by two or more processors or programs. The audio output unit 206 includes, for example, a signal processing circuit, an amplifier, and a speaker.

2. Operation FIG. 5 is a flowchart showing operations of the input device 10 and the song synthesis control device 20. The flow in FIG. 5 is executed, for example, during a period in which the input device 10 and the song synthesis control device 20 are turned on.

  In the input device 10, the first designation unit 102 determines whether or not at least one of the switches 111 to 113 is pressed based on the detection result of the operation detection unit 101 (step S11). When it is determined that none of the switches is pressed (step S11; NO), the first designation unit 102 stands by. When it is determined that at least one of the switches 111 to 113 has been pressed (step S11; YES), the first designation unit 102 designates a vowel (step S12). The first designation unit 102 designates one of vowels among [a], [i], [u], [e], and [o] according to the operation state of the switches 111 to 113, and A semi-vowel for expressing a stuttering is designated according to the operation state of the switch 114.

  Next, the motion detector 103 detects the motion of the input device 10 (step S13). The second designation unit 104 designates a consonant according to the direction in which the input device 10 is detected detected by the motion detection unit 103 and the operation state of the switch 115 and the switch 116 detected by the operation detection unit 101 ( Step S14). The second designating unit 104 selects [a], [k], [s], [t], [n], [h], [m], [g], [z] (zag), [d] One of the consonants is specified among (line), [b] (line), and [p] (line).

  Next, the transmission part 105 transmits the designated vowel and consonant to the song synthesis control apparatus 20 (step S15). After this transmission, the process of the input device 10 is returned to step S11. That is, the transmission unit 105 transmits vowels and consonants to the singing synthesis control device 20 while at least one of the switches 111 to 113 is pressed.

  In the singing synthesis control device 20, the receiving unit 201 determines whether or not a vowel and a consonant have been received from the input device 10 (step S21). If it is determined that vowels and consonants are not received (step S21; NO), the receiving unit 201 waits. When it is determined that a vowel and a consonant have been received (step S21; YES), the determination unit 203 determines whether or not at least one of the operators 211 has been pressed based on the detection result of the operation detection unit 202 ( Step S22). When it is determined that none of the operators 211 is pressed (step S21; NO), the processing of the singing synthesis control device 20 is returned to step S21.

  If it is determined that at least one of the operators 211 has been pressed (step S22; YES), the determination unit 203 determines a pitch corresponding to the pressed operator 211 (step S23). The determination unit 203 determines a pitch specific to the operator 211. An operator 211 is an operator imitating a key. Therefore, the determination unit 203 may determine a higher pitch as the operator 211 corresponding to a key corresponding to a higher pitch is pressed.

  The synthesis instruction unit 204 instructs the voice synthesis unit 205 to synthesize the singing voice based on the received consonants and vowels and the determined pitch (step S24). Specifically, the synthesis instruction unit 204 converts the lyrics determined according to the consonant and the vowel into phonetic symbols, generates an instruction for synthesizing the phonetic symbol and the voice of the determined pitch, and sends it to the voice synthesis unit 205. Output. The voice synthesizer 205 synthesizes a singing voice according to the inputted synthesis instruction (step S25). Since a well-known technique can be used for synthesis of the singing voice, only the outline will be described here. The speech synthesis unit 205 has a segment library. The segment library is a database including musical segments (singing voice fragments) sampled from a voice of a specific singer. The segment library includes a plurality of segment data collected from the singing voice waveform of the singer. Segment data refers to speech data obtained by extracting and encoding phonetic features from a singing speech waveform.

  Here, the case of synthesizing the singing voice of the lyrics “sai” with respect to the segment data will be described as an example. The lyrics of [sai] are represented by phonetic symbols [saita]. When the waveform of the voice represented by the phonetic symbol [saita] is analyzed by features, the rising part of the sound of [s], the sound of [s], the transition part from the sound of [s] to the sound of [a], [ The sound of [a] is continued and ends with the attenuation part of the sound of [a]. Each piece of data is audio data corresponding to these phonetic features. The element change library stores element data relating to all sounds and combinations of sounds. In the following description, segment data corresponding to the rising portion of a sound represented by a phonetic symbol is represented as [#s] with [#] in front of the phonetic symbol. In addition, segment data corresponding to a sound attenuation portion represented by a certain phonetic symbol is expressed as [a #] by adding [#] after the phonetic symbol. Further, segment data corresponding to a transition portion from a sound represented by a certain phonetic symbol to a sound represented by another phonetic symbol is inserted between those phonetic symbols, and [s-a ].

  For example, a voice [Pa] is synthesized by arranging and connecting segment data [#p], [p], [pa] and [a] in order. The speech synthesizer 205 adjusts the pitch after combining these segment data. The speech synthesizer 205 outputs a sound signal of synthesized speech whose pitch is adjusted. The voice output unit 206 outputs a synthesized voice according to the sound signal output from the voice synthesis unit 205 (step S26).

  Next, the synthesis instruction unit 204 determines whether or not the vowel or consonant received from the input device 10 has changed (step S27). Specifically, the synthesis instruction unit 204 determines whether at least one of the vowels and consonants has changed, and whether the vowels and consonants are no longer received. If it is determined that there is no change in the vowels and consonants (step S27; NO), the synthesis instruction unit 204 determines whether there is a change in pitch (step S28). Specifically, the composition instruction unit 204 determines whether the operator 211 is no longer pressed (a finger is released from the operator 211) and whether another operator 211 is pressed. When it is determined that there is no change in the pitch (step S28; NO), the synthesis instruction unit 204 does not instruct the synthesis of a new singing voice. Specifically, the processing of the leaf and singing synthesis control device 20 is returned to step S25, and the speech synthesis unit 205 continues to output synthesized speech of the same lyrics (characters) using the speech output unit 206 (step S25). , S26). The speech synthesizer 205 outputs a sound signal that continues to extend the last vowel ([a] in the previous example).

On the other hand, when the synthesis instruction unit 204 determines that the vowel or consonant received from the input device 10 has changed (step S27; YES), or when the pitch has been changed (step S28; YES). The process of the song synthesis control device 20 is returned to step S21.
When the vowel and the consonant are received from the input device 10 (step S21; YES) and the pitch is specified by the operation of the operator 211 (step S22; YES), the synthesis instruction unit 204 receives a new one. The voice synthesis unit 205 is instructed to synthesize the singing voice, and singing voice is synthesized and the synthesized voice is output (steps S23 to S26).

  According to the speech synthesizer 1 described above, the user can hold the input device 10 with one hand, and can specify vowels and consonants of lyrics by an operation of pressing a switch and an operation of moving the input device 10. Furthermore, the user can designate the pitch of the lyrics by operating the singing synthesis control device 20 with the other hand. Therefore, the user can easily specify the vowels, consonants, and pitches of the lyrics, and cause the singing synthesis control device 20 to output the synthesized speech.

The type and number of switches provided on the contact surface 11A of the gripped portion 11 are not limited to the example of FIG. In this modified example, as shown in FIG. 6, the contact surface 11A is not provided with a switch 115 for designating muddy sound and 116 for designating semi-turbid sound. Instead, a switch 117 for switching modes is provided. . While the switch 117 is off, the first designation unit 102 uses [a], [k], [s], [t], [n], [n], as consonants as shown in the left diagram of FIG. [H], [m], [y], [r] can be specified. On the other hand, as long as the switch 117 is on, the first designation unit 102 uses [y], [w], [g], [z], [d ], [B], and [p] can be specified.

  FIG. 8 is a diagram illustrating the structure of the grasped portion 11 according to another modification, and FIG. 9 is a diagram illustrating the relationship between the movement of the grasped portion 11 and the specified consonant. The input device 10 may designate a consonant according to the operation of a switch provided on the contact surface 11 </ b> A and a vowel according to the movement of the input device 10. In this example, as shown in FIG. 8, switches 111 to 114 and 118 are provided on the contact surface 11 </ b> A as switches for designating consonants. In this case, a total of 16 consonants including clear sound, muddy sound and semi-muddy sound can be designated by the combination of on / off of the four switches 111 to 113 and 118. The switch 114 is a switch for designating whether or not the stuttering is used, as in the above-described embodiment. As shown in FIG. 9, in this modification, a first specifying unit 106 and a second specifying unit 107 are provided instead of the first specifying unit 102 and the second specifying unit 104. The first designation unit 106 designates a consonant among the vowels and consonants of the lyrics according to the operation state of the switches 111 to 113 and 118 detected by the operation detection unit 101. The second designation unit 107 designates the vowels of the lyrics vowels and consonants of the singing voice according to the operation state of the switch 114 and the movement of the input device 10 detected by the movement detection unit 103. The transmitting unit 105 transmits the consonant specified by the first specifying unit 106 and the vowel specified by the second specifying unit 107 to the singing synthesis control device 20. The configuration of the singing synthesis control device 20 may be the same as that of the above-described embodiment.

  FIG. 10 is a flowchart showing operations of the input device 10 and the song synthesis control device 20 according to this modification. The flow in FIG. 10 is executed, for example, while the input device 10 and the song synthesis control device 20 are powered on. In the input device 10, the first designation unit 106 determines whether at least one of the switches 111 to 113 and 118 has been pressed based on the detection result of the operation detection unit 101 (step S31). When it is determined that none of the switches is pressed (step S31; NO), the first designation unit 106 stands by. When determining that at least one of the switches 111 to 113 and 118 has been pressed (step S31; YES), the first designation unit 106 designates a consonant (step S32).

  Next, the motion detector 103 detects the motion of the input device 10 (step S33). The second designation unit 107 designates a vowel according to the direction of movement of the input device 10 detected by the motion detection unit 103 (step S34).

  Next, the transmission part 105 transmits the designated consonant and vowel to the song synthesis control apparatus 20 (step S35). After this transmission, the process of the input device 10 is returned to step S31. That is, while at least one of the switches 111 to 113 and 118 is pressed, the transmission unit 105 transmits the consonant and the vowel to the song synthesis control device 20.

3-2. The relationship between the movement of the input device 10 and the consonant The relationship between the direction of movement of the input device 10 and the specified consonant described in the above-described embodiment is merely an example. For example, a three-axis orthogonal coordinate system may be defined, and different consonants may be associated with each axial direction. Further, the movement of the input device 10 is not limited to the vibration of the input device 10 and may be a change in the posture of the input device 10 (rotation, twist) or the like. The input device 10 should just be comprised so that the consonant or vowel according to the motion may designate.

3-3. Other Modifications The specific shape of the input device 10 is not limited to that illustrated in the embodiment. For example, the input device 10 may be a rod-shaped device such as a guide light for traffic control. Further, the input device 10 may not have a lighting function, and may be, for example, a walking stick or a command stick. The shape of the input device 10 is not limited to a rod shape, and may be a device that is not a rod shape, such as a dumbbell or a device (for example, a glove-type device) that is attached to a body part of a user. . The input device 10 may be a portable device (for example, a smartphone). In this case, the input device 10 may detect the movement of the user's finger tracing the surface of the touch screen and specify a vowel or consonant corresponding to the movement. In this case, the direction in which the finger moves on the touch screen may be associated with the vowel or consonant.

  The input device 10 may detect the movement of the input device 10 only during a period in which a switch used for designating a vowel or consonant is being pressed. Thereby, compared with the case where the movement of the input device 10 is always detected, a reduction in power consumption of the input device 10 can be expected.

  An operator used for designating a vowel or consonant in the input device is not limited to a momentary switch. Instead of or in addition to the momentary switch, an alternate switch may be used. Alternatively, a lever, a slider, a dial, or the like may be used instead of or in addition to the switch.

  The singing synthesis control device 20 may not have an external appearance imitating an electronic keyboard instrument, may have an external appearance imitating a stringed instrument, a wind instrument, a wind instrument, or the like, or imitate an instrument. It does not have to be the appearance. Singing synthesis control device 20 should just have a function which controls composition of at least singing voice. The number of operators included in the operation unit 21 may be any number as long as it is one or more.

  A part of the configuration or operation of the input device 10 and the singing voice synthesis control device 20 described in the above-described embodiment may be omitted. For example, the input device 10 may be configured not to specify at least one of stuttering, muddy sound, and semi-muddy sound.
