Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a document reading apparatus, and more particularly to a document reading apparatus that can efficiently retrieve a desired constituent sentence by reading out the number of components of the document or by simply reading out the constituent sentence.
[0002]
[Prior art]
Normally, sentences exist with a visual layout structure. When a search is performed by listening to this over the telephone or the like, an efficient reading method is desired that is easy to understand.
[0003]
[Problems to be solved by the invention]
Therefore, the necessary information can be effectively searched using the structure information of the document. As an example of use, it is assumed that the guidance document has already been received as an electronic document and read once. Since the structure is already known when confirming the place from the outside, the target portion can be read quickly by searching according to the document structure.
[0004]
Analyzing the inclusive relations and parallel relations of each part of the document, reading out the text including the structure by speech synthesis, and improving the searchability for the contents by selecting and giving priority in the structural unit. For example, in the previous guide letter, it is assumed that the destination, the destination, the guidance text, and the guidance items are itemized. In such a case, the structure can be read out first by reading out the configuration and selecting the guidance item.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 analyzes the data structure of the input structured document data, stores the read-out data in a storage device, and reads out the read-out data according to the user's instruction. the category of each hierarchy reading toward the uppermost layer from the current layer, comprising means Ru is to locate the current hierarchy, before read the configuration statement in each layer, the contents of the configuration statement of the hierarchy while you are reading in a simplified, said to confirm the position read by means Ru is to locate the current hierarchy is obtained by said Rukoto.
[0009]
The invention of claim 2 analyzes the data structure of the input structured document data, stores the read-out data in a storage device, and reads out the read-out data according to the user's instruction. When reading the classification items of each hierarchy from the current hierarchy to the highest hierarchy, it has a means for confirming the position of the current hierarchy, which can stop reading halfway or skip the middle hierarchy classification, before read the configuration statements in the hierarchy, while you are reading and simplified contents of the configuration statement in the corresponding hierarchy, which was characterized by the fact that make sure the position read by the verify causes means the position of the current hierarchy is there.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a main part for explaining an embodiment of a document reading apparatus according to the present invention. In the figure, 1 is a data input device for inputting structured document data, and 2 is an inputted structured data. Data structure analysis device for analyzing data structure of document, 3 is a reading data storage device, 4 is a reading control device, 5 is a voice data storage device for guide, 6 is a past reading order data storage device, and 7 is operated by a user. , A reading operation input device that operates the reading control device 4, 8 is a speech synthesizer, 9 is an acoustic signal generator, 10 is an output device such as a speaker, and the structured document data input to the data input device 1 is data The structure is analyzed and stored in the reading data storage device 3. This read-out data is sequentially read out by operating the read-out control device 4 by the read-out operation input device 7 operated by the user. At this time, a guide voice and sound are output, and the current read-out position is known. In addition, by knowing the current reading position, the position to be heard can be selected efficiently.
[0019]
First, the reading forms read out by the document reading apparatus according to the present invention will be listed.
○ Read the structure of the document. For example, the number of paragraphs and the number of bullet items.
・ Read the contents of each component easily.
Read the first part.
Read frequently used phrases.
Summarize the contents.
[0020]
○ Read the headline in the document structure section and specify the reading priority.
・ Specify the reading priority for each item as a relative value or absolute value by active operation such as numeric key input from the listener.
・ When reading out items, use keystrokes to skip reading or reading out detailed contents.
[0021]
○ Check the reading position with the guide voice.
・ Read the route from the top layer to the current location.
-Read the route from the appropriate position in the hierarchy to the current hierarchy.
・ Read in reverse order from the current level to the highest level. In this case, it may be stopped halfway by a listener operation.
・ Read the position of the top layer and the current layer, omitting the middle.
・ If the text is long, say where it is. For example, the beginning of anything, the middle, etc.
・ In the part where items are listed, say what number.
[0022]
○ How to communicate the relationship before and after moving the hierarchy.
-Read the destination location with a guide voice.
-When moving, put a silent part and an acoustic signal, and express the moving distance by the length and number of times. You can imagine the amount of documents skipped.
・ Change the speed and pitch of the acoustic signal according to the moving direction of the hierarchy. For example, when moving to a higher level, the sound is lowered, and when moving to a lower level, the sound is increased.
[0023]
Conventionally, there is a service that guides product information by telephone, but they construct a dedicated database to guide product classification. On the other hand, in the present invention, by extracting the structure from a normal document, the search performance is improved without constructing a dedicated system.

【The invention's effect】
By using the structure information of the document, it is possible to effectively search for necessary portions. As an example of use, it is assumed that the guidance document has already been received as an electronic document and read once. Since the structure is already known when confirming the place from the outside, the target portion can be read quickly by searching according to the document structure.
Analyzing the inclusive relations and parallel relations of each part of the document, reading out the text including the structure by speech synthesis, and improving the searchability for the contents by selecting and giving priority in the structural unit. For example, in the previous guide letter, it is assumed that the destination, the destination, the guidance text, and the guidance items are itemized. First, the structure can be read aloud, and the guidance item can be selected for efficient reading.
