The voice recognition device 40 is configured to convert a registered voice instruction into command data. The generated command data includes a command code that can be executed by the stage mechanism control device 50. The detailed configuration of the command data will be described later.

  The stage mechanism control device 50 is configured to be able to communicate with a plurality of stage devices 60_1 to 60_n. As a communication method, either wired or wireless communication is possible. In the present embodiment, a case where the stage mechanism control device 50 communicates directly with each stage device will be described.

Each stage device may transmit status information to the stage mechanism control device 50 together with identification information (device name or device number) for identifying the device itself.

[Operation of voice operation system]
Next, the operation of the voice operation system 100 according to the present embodiment will be described.

  FIG. 3 is a diagram for explaining the flow of data among the operator, the voice operation system 100, and the stage mechanism.

  Referring to FIG. 3, first, the operator inputs a voice instruction to voice type operating device 10 (OP1 in the figure). When receiving the voice instruction from the operator, the voice operation apparatus 10 transmits voice data indicating the voice instruction to the voice recognition apparatus 40.

  When the voice recognition device 40 receives a voice instruction (voice data) from the voice type operation device 10, the voice recognition device 40 registers the received voice instruction. The voice recognition device 40 converts voice instructions that are voice data into command data. Specifically, the voice instruction from the operator includes stage device identification information in order to identify the stage device to be operated. The voice instruction further includes operation information indicating the operation content of the stage apparatus to be operated. The voice recognition device 40 converts the identification information and the operation information into a command code that can be executed by the stage mechanism control device 50.

FIG. 4 is a diagram for explaining an aspect of code conversion in the speech recognition apparatus 40.
Referring to FIG. 4, voice recognition device 40 stores a plurality of command codes. Each of the plurality of command codes is associated with identification information or operation information.

  In the example of FIG. 4, the plurality of command codes include a code associated with the device name of the stage device (for example, codes 001 to 100) and a code associated with the operation amount of the stage device (for example, codes 101 to 200). And codes (for example, codes 201 to 300) associated with the operation direction of the stage apparatus.

  The device name of the stage device includes, for example, names of large tools, lighting fixtures, screen equipment, notebooks, acoustic reflectors, and the like, or the names of hanging mechanisms that raise and lower them, and names of floor mechanisms. A command code can be assigned to each stage apparatus. Alternatively, when a plurality of stage apparatuses are grouped as a group of two or more stage apparatuses that require collective operation, a command code can be assigned to each group.

  The operation amount of the stage device includes, for example, the moving distance and rotation angle of the stage device. For example, for each of the movement distance and the rotation angle, the allowable range can be subdivided, and a code can be assigned to each subdivided range. The amount of movement of the stage device includes, for example, the height position of the stage from the floor and other target positions of the stage device. A code can be assigned for each target position.

  The operation direction of the stage apparatus includes, for example, the up-down direction, the front-rear direction, the left-right direction, the rotation direction, and the like. A code can be assigned to each of these directions.

  The voice recognition device 40 stores a table showing the correspondence between identification information and operation information and a plurality of command codes, as shown in FIG. When the voice recognition device 40 receives a voice instruction from the voice operation device 10, the voice recognition device 40 refers to the table and converts the voice instruction into a code.

  Here, for example, as shown in FIG. 5, a case is assumed in which the voice instruction from the operator is “lift the notebook to 22 m above the floor”. This voice instruction is made up of “tap” (device name) that is identification information of the operation target, “22 m above the floor” (target position) that is the operation amount of the operation target, and “rise” that is the operation direction of the operation target. It consists of three words. In this case, the speech recognition device 40 refers to the table and converts each of the three words to a command code. The voice recognition device 40 generates command data by combining the converted command codes.

  In the example of FIG. 5, the phrase “book” is converted to the command code “001”, the phrase “22 m on the floor” is converted to the command code “122”, and the phrase “rising” is converted to the command code “210”. Is done. Therefore, the voice instruction “raise the pad to 22 m above the floor” is converted into command data including the command code “001, 122, 210”.

  In addition, in order to ensure the accuracy of the code conversion process in the voice recognition device 40, the syntax (word order) of the voice instruction can be determined in advance. For example, as shown in FIG. 5, the order of identification information, operation information (motion amount), and operation information (motion direction) can be used.

  Alternatively, an instruction for starting transcoding can be included at the beginning of the voice instruction. For example, when receiving a voice instruction “command”, the voice recognition device 40 may start the code conversion process and convert the voice instruction input following the “command” into a command code.

  Returning to FIG. 3, when receiving the command data from the speech recognition device 40, the stage mechanism control device 50 generates information such as characters representing the received command data. Specifically, the stage mechanism control apparatus 50 converts the received command data back into information such as characters by referring to the table of FIG. For example, when the command data shown in FIG. 5 (codes “001, 122, 210”) is received, the stage mechanism control device 50 uses the command data to display three phrases, “padbook”, “22 m above the floor”, and “rise”. And information such as characters including the extracted three phrases is generated.

  When the stage mechanism control device 50 acquires the status information from each of the plurality of stage devices 60_1 to 60_n, the stage mechanism control device 50 extracts the status information of the stage device to be operated from the acquired status information. At this time, the status information of the stage apparatus linked to the stage apparatus to be operated can be extracted together. The stage apparatus linked to the stage apparatus to be operated is, for example, a stage apparatus having a movable range overlapping with the stage apparatus to be operated.

  The stage mechanism control device 50 converts the extracted status information into information such as characters. The stage mechanism control device 50 transmits information such as the generated characters to the display device 30.

  The display device 30 displays information such as characters generated by the stage mechanism control device 50 on the display screen. FIG. 6 is a diagram for explaining an example of a screen displayed on the display device 30. Referring to FIG. 6, the display screen of display device 30 includes “device name”, “attribute name”, “speed”, “target position”, “current position”, “motion direction”, and “status”. Seven items are listed.

  In “device name”, the name of the stage device to be operated is displayed. The device number assigned to the stage device may be used. In the “attribute name”, information for specifying a group to which the stage device to be operated belongs is displayed.

  In “Speed”, a target speed at which the stage apparatus to be operated is to be operated is displayed. In “target position”, the target position of the stage apparatus to be operated is displayed. In “current position”, the current position of the stage apparatus to be operated is displayed.

  In “Status”, status information of the stage apparatus to be operated is displayed. For example, information indicating whether the stage apparatus to be operated is currently operating or stopped, information indicating whether the stage apparatus is normal, or an abnormality has occurred, and the like are displayed. The “status” may also display status information of the stage device linked to the stage device to be operated.

  As described above, the display screen of the display device 30 displays the contents of the voice instruction registered based on the voice input OP1 of the operator and the status information of the stage apparatus to be operated specified by the voice instruction. The The operator looks at the display screen to confirm whether or not his / her voice input OP1 matches the registered voice instruction, that is, whether or not his / her voice instruction is correctly registered. (OP2 in FIG. 3).

  In addition, since the operator can grasp the current state of the stage device to be operated by looking at the display screen, it is necessary to confirm whether the stage device can be operated according to the voice instruction. (OP2 in FIG. 3).

  For example, if there is an operator's misunderstanding about the current position of the stage device to be operated, if the stage device is operated according to the voice instruction, the stage device moves to a position different from the intention of the operator, and the May affect the stage equipment. Alternatively, when the stage device to be operated is operating in accordance with a voice instruction from another operator, there is a possibility that the voice instruction of the other operator and his / her voice instruction may be batting. The operator can foresee the possibility of these problems by grasping the current state of the stage apparatus to be operated from the display screen.

  Returning to FIG. 3, when it is confirmed that the voice instruction is correctly registered and the stage device to be operated can be operated according to the voice instruction (OP 2 in the figure), the operator An input operation is performed on the operation unit of the operation device 30 (OP3 in the figure). The operator performs an input operation to an operation button corresponding to an operation command for operating the stage apparatus to be operated among the plurality of mechanical operation buttons included in the operation unit.

  When an input operation is performed on the operation button, the mechanical operation device 30 generates an operation command and outputs it to the stage mechanism control device 50. The stage mechanism control device 50 generates a control command (electric signal) for controlling the stage device to be operated based on the operation command from the mechanical operation device 30. The stage mechanism control device 50 outputs the generated control command to the stage device to be operated. As a result, the stage device to be operated operates according to the voice instruction.

  In addition, during operation of the stage apparatus to be operated, when it is desired to stop the stage apparatus against the voice instruction, the operator performs an input operation to the operation button corresponding to the stop command with the mechanical operation apparatus 30. Can be performed.

  On the other hand, if it is confirmed that the voice instruction is registered incorrectly, such as when there is an error or omission in the registered content, or the voice instruction is correctly registered, When it is confirmed that the stage device cannot be operated, the operator can input a voice instruction to the voice operation device 10 again (OP1 in the figure). Then, the operator also operates the stage apparatus to be operated in accordance with the voice instruction based on the display screen of the display device 30 for the newly input voice instruction and whether the voice instruction is correctly registered. Can be confirmed again (OP2 in the figure).

  As described above, in voice operation system 100 according to the present embodiment, a voice instruction registered in voice recognition device 40 is converted into command data and transmitted to stage mechanism control device 50. Thereafter, the command data is reversely converted into information such as characters by the stage mechanism control device 50 and displayed on the display screen of the display device 20. That is, the voice instruction given from the operator is fed back to the operator as information such as characters. Thereby, the operator can confirm whether or not the voice instruction issued by himself / herself is correctly registered in the voice operation system 100 based on information such as characters.

  Further, since the status information of the stage device to be operated is displayed as information such as characters on the display screen of the display device 20 in addition to the voice instruction, the operator designates the stage device to be operated as a voice instruction. It can be confirmed whether or not it can be operated safely according to the above.

  Furthermore, when it is confirmed that the voice instruction is correctly registered and the stage device to be operated can be safely operated, the operator operates the mechanical operation device 30 to operate the operation target. The stage equipment can be operated. In other words, the operation of the stage apparatus to be operated is executed not by a voice instruction from the operator but by a manual instruction by the operator as a trigger. In this way, since the voice instruction is correctly registered and the safe operation of the stage apparatus to be operated is guaranteed, the stage apparatus to be operated can be operated. The safe and accurate operation of the stage equipment can be realized.

  Further, in the conventional operation device, since the operator usually operates according to the instruction from the conductor at the site in an operation room or the like away from the site, the state of the stage device to be operated is determined through voice instructions from the conductor. There was a situation that could only be known. On the other hand, according to voice operation system 100 according to the present embodiment, the conductor himself / herself operates as an operator to operate the stage apparatus, so that the operator can visually recognize the state of the stage apparatus to be operated. it can. Furthermore, since the operator does not require a complicated manual operation in the mechanical operation device 30, the operator can concentrate his / her line of sight on the stage device to be operated. As a result, the operator can operate the stage apparatus accurately and safely while grasping the latest state of the stage apparatus to be operated.

  Further, according to the voice operation system 100, the operator issues an instruction by voice, and the instruction content is visually confirmed in the form of information such as characters, so the instruction and the confirmation are performed in parallel without confusion. Can do. Thereby, the operator can perform operation efficiently.

  Specifically, in the voice recognition technology, there is a method in which when an operator issues an instruction by voice, the instruction content is notified to the operator by voice so that the operator confirms the instruction. However, in such a system, since pronunciation and listening sound are mixed, it is difficult to perform the instruction and the confirmation in parallel. Therefore, by confirming after the instruction, the confusion of the operator is avoided.

  On the other hand, in the present embodiment, as described above, instructions are issued using auditory senses and confirmed using visual senses, so that the operator performs instructions and confirmations in parallel without confusion. Can do. Therefore, the operation efficiency of the stage mechanism can be improved.

  Further, in the voice operation system 100, as shown in FIG. 6, the operator is registered by displaying the identification information and the operation information of the stage apparatus to be operated as a list on the display screen of the display device 30. You can easily find that there are mistakes or omissions in the voice instructions.

  Furthermore, when the operator issues a voice instruction while viewing the list on the display screen, the operator can be prompted to make the voice instruction in a syntax format following the list. For example, a plurality of items listed in the list of FIG. 6 can be input by voice in order from the top item. According to this, the recognition accuracy in the speech recognition apparatus 40 can be increased.

  However, in the voice operation system 100 according to the present embodiment, when an abnormality occurs in the voice operation system 100, such as when any of the plurality of stage devices 60_1 to 60_n fails, the entire plurality of stage devices 60_1 to 60_n An emergency stop is required. In such a case, the operator who has detected an abnormality can input a voice instruction such as “emergency stop” to the voice operation device 10. When the voice instruction for emergency stop is converted into command data by the voice recognition device 40 and given to the stage mechanism control device 50, the stage mechanism control device 50 quickly does not wait for a manual command from the mechanical operation device 30. The entire stage apparatuses 60_1 to 60_n can be stopped.

[Voice recognition in voice operation system]
A configuration example for voice recognition in voice operation system 100 according to the present embodiment will be described below with reference to FIGS. Each of FIGS. 7 to 9 exemplifies a case where two operators OPA and OPB issue voice instructions independently of each other. There may be three or more operators.

  FIG. 7 is a diagram illustrating a first configuration example of voice recognition that can be applied to the voice operation system 100. Referring to FIG. 7, operator OPA can issue a voice instruction and a manual instruction using voice operation device 10 </ b> A and mechanical operation device 30 </ b> A, respectively.
