And mode control switch 13b and communication device 13
f is provided. Furthermore, the communication device 13f is connected to the signal processing device 15.

The mode control switch 13b performs an operation of switching between driving and stopping of the control device 3, and also performs processing of switching between two control modes of "text reading processing" or "text reading position control".
Each of these modes will be described later.

The communication device 13f is the signal processing device 15
When the driving operation is performed by the mode control switch 13b, the information output from the signal processing device 15 is output to the wheel control CPU 13d.

FIG. 4 is an explanatory view schematically showing the connection relationship among the wheel 13a, the drive motor 13c, and the wheel position sensor 13e. As shown in FIG. 4, the wheel 13a is connected via the shaft 14. The wheel position sensor 1 is connected to the output shaft of the drive motor 13c.
3e is arranged near the wheel 13a so that the rotation angle of the wheel 13a can be detected.

FIG. 5 is an explanatory view showing how the wheel 13a is mounted on the steering wheel 8 of the vehicle. The wheel 13a can be easily operated with one hand while the driver is operating the steering wheel 8. It is attached to the proper spoke 9 in place. Then, as shown in FIG. 6, a desired operation amount can be input by reversibly rotating the wheel 13a. Also, the wheel 13a
It is also possible to provide a push select function by pressing.

Further, as shown in FIG. 7, the wheel 13a
It is also possible to arrange the mode control switch 13b in the vicinity of the side portion of.

Next, FIG. 8 shows the first processing operation of the speech conversion apparatus 100 according to the present embodiment configured as described above.
This will be described with reference to the flowchart shown in FIG. In addition,
In the description here, a case will be described as an example in which text data such as e-mail or distributed news is converted into voice data and presented to a driver of a vehicle or other occupants as input data.

First, the data input section 1 acquires the transmission data transmitted from the information communication base station 7 shown in FIG.
This is downloaded (D / L) (step S000).
Thereby, the text data can be obtained (step S001).

Next, the signal processing unit 15 shown in FIG. 3 divides the obtained text data into clauses (steps S002, S003). For example, when the text data as shown in FIG. 9 is given, as shown in FIG. 10, the text data is divided into each clause,
Furthermore, the index Ist (Ist = 0, 1, 2,
・ ・) Is added (step S004). In this example, Ist =
The phrase that becomes 0 becomes the text data of "paid music distribution service".

Then, the entire text data is divided into phrases (YES in step S002), and when the mode control switch 13b is turned on by the operator, a process of reading the text data is started (step S005), and the phrase is read. Index Ist of is reset to zero (step S006).

Next, when the text reading process mode is selected by the mode control switch 13b (NO in step S007 and YES in S008), the phrase of the index Ist is converted into voice by the voice conversion unit 2. (Step S013), the audio output unit 4 outputs. That is, the text data is read aloud. Further, the index Ist is incremented (step S014) to continue reading the text data.

After that, the index Ist becomes "n" (n
Is the index number of the last phrase (YES in step S007), it means that all the text data has been read aloud, and the reading process by voice is terminated (step S012).

On the other hand, when the wheel 13a is operated, the mode is switched to the text reading position control mode (YES in step S009), and the wheel 13a is rotated to become a reading target in the text data. You can change the clause index. For example, when reading the phrase “Monthly usage fee is” with index Ist = 1 shown in FIG.
By rotating 3a by a predetermined angle, it is possible to shift to the phrase "July 25, US time" of index Ist = 9.

At this time, the wheel control CP shown in FIG.
In U13d, the operation reaction force acting on the wheel 13a is set according to the index Ist of the selected phrase and the operation angle of the wheel 13a (step S01).
0).

The relationship between the index Ist, the operation angle ω, and the generated operation reaction force (torque) N is represented by the following equation (1) when the index number of the final clause is n.

N = −k (Ist / n) * ω (1) The negative sign “−” indicates that the operation reaction force acts in the direction opposite to the operation direction. Further, k is a coefficient.

The relationship between the operation angle ω and the operation reaction force N is a characteristic curve as shown in FIG. 11, and the operation reaction force N changes in proportion to the magnitude of the operation angle ω. That is, as the rotation angle of the wheel 13a increases, the operation reaction force increases. Note that, here, as an example, the case where the operation angle ω and the operation reaction force N have a proportional relationship is described, but the operation angle ω and the operation reaction force N may be set so as to change in a smooth curved shape.

In addition, "k (Ist / n)" and "Ist /
As shown in FIG. 12, the relationship with "n" changes in three steps such that it decreases as "Ist / n" increases (as it approaches 1). In the figure, "H" indicates the first 1/3 clause when all text data is divided into 3 parts, and "M" indicates the middle 1/3 clause.
“S” indicates the last 1/3 clause.

Therefore, the coefficient "k (Ist / n)" decreases from the index Ist = 0 toward the end of the sentence, and the operation reaction force changes in three steps. As a result, the operator can recognize the change in the magnitude of the operation reaction force by tactile sensation, and easily grasp the current reading position (position of the phrase to be set) in all text data. Will be able to.

In this way, in the vehicle-mounted voice conversion device 100 according to the present embodiment, the reading position of the text data can be appropriately changed by rotating the wheel 13a, so that the visual sense is required. It is possible to search for a desired reading position without (without looking at the display or the like). In addition, since the operation reaction force of the wheel changes according to the current position of the phrase with respect to the entire text data, the operator can easily recognize the current reading position in all the text data.

As a result, it is possible to grasp the remaining amount of the currently processed text data without relying on the visual sense, and the operator can continue the reading process of the text data, or control the middle stage, skip, and back. Can be accurately judged. Further, it is possible to appropriately determine whether the read out data should be dealt with immediately or later.

In the present embodiment, the index Ist
Although an example in which the value of the coefficient “k (Ist / n)” changes in three steps is shown in correspondence with the change of, it is also possible to set it in two steps or four or more steps.

Next, the second processing operation of this embodiment will be described with reference to the flowchart shown in FIG. The flowchart is different from the flowchart shown in FIG. 8 only in the process of “step S110”. That is, in this processing operation, the phrase index Ist and
This is different from the above-described first processing operation in that the control is performed so that an operation reaction force is generated according to a change in the operation amount. Here, “change in manipulated variable” is the time derivative of the manipulated variable,
Control is performed so that an operation reaction force N having a magnitude proportional to the rotational speed of operating the wheel 13a is generated.

Therefore, the index Ist, the operation angle ω,
The relation between the generated operation reaction force (torque) N and the generated reaction force (torque) N is expressed by the following equation (2), where n is the index number of the final clause.

N = −B (Ist / n) * dω / dt (2) As in the above, the negative sign “−” has the operation reaction force in the direction opposite to the operation direction. It is shown that. Also, B
Is a coefficient.

Then, the time differential value dω / dt of the operation angle
, And the operation reaction force N becomes a characteristic curve as shown in FIG. 14, and the operation reaction force N changes in proportion to the magnitude of the differential value dω / dt.

Further, "B (Ist / n)" and "Ist /
As shown in FIG. 15, the relationship with “n” changes in three steps such that it becomes smaller as “Ist / n” becomes larger (closer to 1). In the figure, "H" indicates the first 1/3 clause when all text data is divided into 3 parts, and "M" indicates the middle 1/3 clause.
“S” indicates the last 1/3 clause.

Therefore, as in the case of the first processing operation described above, the coefficient "B (Ist / n)" decreases from the index Ist = 0 toward the end of the sentence, and the operation reaction force decreases in three steps. Changes to. As a result, the operator can recognize the change in the magnitude of the operation reaction force by tactile sensation, and can easily grasp the current reading position in all the text data.

That is, it becomes possible to recognize the current reading position without restraining the visual sense, and to judge whether the read data should be dealt with immediately or later. It can be done properly.

Next, the third processing operation of this embodiment will be described with reference to the flowchart shown in FIG. The flowchart is different from the flowchart shown in FIG. 8 only in the process of “step S210”. That is, in this processing operation, the operation reaction force corresponding to only the phrase index Ist (that is, not depending on the rotation angle of the wheel 13a) is controlled to be generated. It differs from the processing operation.

Therefore, the relationship between the index Ist and the generated operation reaction force (torque) N is represented by the following expression (3) when the index number of the final clause is n.

N = −τ (Ist / n) (3) As in the above, the negative sign “−” indicates that the operation reaction force acts in the direction opposite to the operation direction. There is. Also, τ
Is a coefficient.

The relationship between the operation angle ω and the operation reaction force N is a characteristic curve as shown in FIG.
With a change in the sign of the operation reaction force N, a constant value is obtained.

Further, "τ (Ist / n)" and "Ist /
As shown in FIG. 18, the relationship with “n” changes in three steps such that it becomes smaller (as it approaches 1) as “Ist / n” becomes larger. In the figure, "H" indicates the first 1/3 clause when all text data is divided into 3 parts, and "M" indicates the middle 1/3 clause.
“S” indicates the last 1/3 clause.

Therefore, similar to the above-mentioned first and second processing operations, the coefficient "τ (Ist / n)" becomes smaller from the index Ist = 0 toward the end of the sentence, and the operation reaction force becomes three stages. It changes to become smaller. As a result, the operator can recognize the change in the magnitude of the operation reaction force by tactile sensation, and can easily grasp the current reading position in all the text data.

That is, it becomes possible to recognize the current reading position without restraining the visual sense.

In each processing operation of the above-described embodiment, the coefficients k (Ist / n) and B (Ist
/ N) and torque itself τ (Ist / n) are
2, When passing through the change points of H to M or M to S shown in FIGS. 15 and 18, the operation reaction force changes discontinuously (that is, with a click feeling) with respect to each change. You can also set By doing so, the operator can surely recognize the change in the operation reaction force, and can more surely grasp the current position with respect to all the text data.

Further, in order to ensure the continuity of the operation reaction force, a discontinuous change of the operation reaction force is generated in the series of loops of steps S001 to S011 (FIGS. 8, 13, and 16). Instead, it is also possible to configure so as to generate a discontinuous change in the operation reaction force when shifting to the next loop.

In the above embodiment, the text data is taken as an example of the input data, but the input data may be music data.

Next, a second embodiment of the present invention will be described. Since the device configuration is the same as that shown in FIGS. 1, 3 and 4, the description of the configuration will be omitted.

In the vehicle-mounted voice conversion device according to the second embodiment, as described in the first embodiment, the operation reaction corresponding to the position of the phrase currently undergoing voice conversion with respect to the entire text data is performed. Perform a process to generate force. Furthermore,
By superimposing on this, an operation reaction force that changes each time a predetermined amount of clauses is read aloud is generated.

The processing operation of the vehicle-mounted voice conversion device according to the second embodiment will be described below with reference to the flowchart shown in FIG. The flowchart shown in FIG. 19 is
The difference from the flowchart shown in FIG. 8 is that the process of step S012 is added.

In this process, the operation reaction force is set to change every time the index Ist increases by a predetermined number (for example, two clauses). That is, in addition to the processing of the first embodiment in which the operation reaction force is generated according to the position of the phrase currently undergoing voice conversion with respect to the entire text data,
Further, a change in the operation reaction force is generated along with the change in the phrase.

20 (a) and 20 (b) are explanatory views showing the operation reaction force generated for each increment of a phrase, FIG. 20 (b) is an overall explanatory view, and FIG. 20 (a) is a detailed explanatory view. In the figure, reference numeral x1 is text data divided into clauses, reference numeral x2
Indicates a group of clauses (in this case, a break for every two clauses), and a symbol x3 indicates a change in the operation reaction force.

Then, from the position of the symbol A in FIG.
Reading position (position of phrase to be set) to the position of code B
When shifting the wheel 13 at the position of symbol C
The operation reaction force generated in a changes. FIG. 21 is an explanatory diagram showing a profile of torque change with respect to the rotation angle of the wheel 13a, and when passing through the position of reference C in FIG. 20, an operation feeling (Detent) as if tracing a depression.
Feeling).

Thus, in addition to the effects of the first embodiment described above, the vehicle-mounted voice conversion device according to the present embodiment is further operated every time when it passes through a position divided for each group of phrases. Since the reaction force is configured to change,
The operator can recognize the transition of the phrase by tactile sensation, and the operability can be significantly improved.

Next, a first modified example of the second embodiment will be described. FIG. 22 is a flowchart showing the processing operation of the vehicle-mounted voice conversion device according to the modification. The flowchart is different from the flowchart shown in FIG. 19 described above only in the process of step S115, and the other processes are the same. That is, in this modification,
The operation reaction force is changed every time the integrated value of the reading required time Tst of each phrase reaches a predetermined value.

Hereinafter, this processing will be described in detail with reference to the explanatory views shown in FIGS. 23 and 24. FIG. 23
Indicates corresponding data created by dividing the text data shown in FIG. 9 described above into clauses. As shown in the figure, this correspondence data describes the reading required time of each clause. That is, for index Ist = 0,
The phrase "Paid music distribution service" corresponds, and the required reading time T (Ist) is described.

At this time, the reading required time T (Ist) is
The character strings contained in each clause are further decomposed into phoneme data,
It is calculated based on the phoneme data included in each phrase and the currently set reading speed.

In this modification, if the integrated value ΣT (Ist) of the reading required time T (Ist) exceeds a preset predetermined value, the operation is performed at the beginning of the next clause. Change the reaction force.

That is, as indicated by reference numeral y1 in FIG.
When text data including each clause is given and the reading position is moved from the position of the code A to the position of the code B, the required time T (Ist) (code y2) described for each clause is given. ) Are sequentially integrated, and when the integrated value exceeds a predetermined value, the operation reaction force is changed at the start point of the next bunsetsu, that is, the position of the code C, as indicated by the code y3 (code (See y4).

With such a configuration, the operator can recognize that the text data for a predetermined reading time has been skipped every time the user feels Detent, and sets the reading position of the text data. Alternatively, it is extremely useful for searching.

Next, a second modified example of the second embodiment will be described. In this modified example, the maximum rotation angle of the wheel 13a is set in advance, and all text data is set to be distributed within this angle range. That is,
If the maximum rotation angle is 360 degrees, the position at the rotation angle of 0 degrees corresponds to the beginning of the text data, and the rotation angle 36
The position of 0 degree corresponds to the end of the text data. Further, similarly to the example shown in FIG. 20, the operation reaction force is set to be changed for each section of one or more clauses.

FIG. 25 is an explanatory diagram showing the clauses and operation reaction forces set by the modified example. Now, when the rotation angle of 0 to 360 degrees of the wheel 13a shown in FIG. 9A is shown as a horizontal scale as shown in FIG. 9B, the entire text data is shown in FIG. As indicated by the symbol a1 of 0, it is distributed from 0 degrees to 360 degrees, and as indicated by the symbol b1, the operation reaction force is set to change for each segment of each clause.

Further, as shown in (d) of the same figure, when text data having a larger total amount than that in the case of (c) above is given, as in the above case, from 0 degrees to 360 degrees. Since the text data is distributed to the range, as a result, the clauses are in a dense state as indicated by reference sign a2, and the operation reaction force changes in a short cycle as indicated by reference sign b2.

Incidentally, "H", "M", shown in FIG.
“S” is the same as that of the first embodiment, and is set so that the operation reaction force becomes smaller in the order of H, M, and S in three stages.

With such a configuration, the entire text data amount can be recognized by the cycle in which the operation reaction force changes. That is, as shown in FIG. 25C, when the amount of text data is small, the cycle in which the operation reaction force changes becomes long, and when the amount of text is large, as shown in FIG. Since the cycle in which the operation reaction force changes becomes short, it is possible to easily grasp the total text amount by feeling this by the sense of touch.

In this way, in the second modification, the rotation angle of the wheel 13a to which the entire text data is assigned is set in advance, and the operation reaction force is changed for each one or a plurality of clauses. The operator can recognize the total amount of text data based on the interval at which a feeling of detent is felt.

Therefore, when the wheel 13a is scrolled, a natural metaphor of change in operation reaction force generated per unit input → distribution density of unit data amount with respect to operation input amount → text data amount is formed, and the operator , It is possible to intuitively recognize the position of text data currently processed and the amount of text data by tactile sense.

As a result, it is possible to grasp the remaining amount of the currently processed text data without relying on the visual sense, and the operator can continue the reading process of the text data, or control the middle stage, skip, and back. Can be accurately judged. Furthermore, since the reading position can be set by rotating the wheel 13a,
The skip and back operations can be freely performed according to the operator's intention.

In the above example, an example in which the entire text data is distributed within the range of 0 to 360 degrees of rotation of the wheel 13a has been described, but the rotation angle of 0 to 360 degrees is not limited to this. Not a thing.
