Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speech information providing apparatus having both the expressive power of speech and the advantage of utilizing visual information.

[0002]

2. Description of the Related Art As means of human communication,
The most basic means is communication using auditory information such as voice. In the communication using auditory information, emotions of a speaker and information outside of words that cannot be expressed by visual information can be expressed in comparison with visual information such as information expressed in a document. Further, it has an excellent feature that information can be obtained while continuing some other work.

[0003] The most prominent example is the name of "speech browser" which reads out an icon displayed on the desktop of a personal computer (hereinafter referred to as "PC") or reads out text displayed on browser software. Or application software marketed under a similar name. Voice browsers read aloud the text of a document to be displayed to the user electronically,
It conveys the contents.

[0004] Most of the software marketed under the name of a voice browser operates on a stand-alone PC, but the voice browsing function can be used in a network information service having a voice reading function. The audio browsing in this case can be roughly classified into two types. As shown in FIG.
A typical client-server system using C and dedicated equipment, and a system in which the user does not use special equipment or software by using only a normal telephone line. is there.

[0005] The former is converted into a command in a dedicated terminal 11 such as a PC in response to a user's input using an input medium such as a keyboard or a mouse or inputting a voice, and the command is converted to a command on the Internet or the like. Is transmitted to the server station 13 through the network line. Then, a response to the command is directly returned as a text from the server station 13, and the dedicated terminal 11 such as a PC reads out the text data.

On the other hand, in the latter case, since the telephone 12 is used as an input medium, the telephone 12 itself does not have a command conversion function, so that the voice data itself is transmitted to the server station 13 and the command data is transmitted to the server station 13. Is converted into a voice as a response to the command in the server station 13 and then transmitted to the telephone 12 for reading out.

As described above, by using the voice browser, a convenient communication tool can be constructed by utilizing the easiness of handling the auditory information.

[0008]

On the other hand, tasks such as quick reading, browsing, and searching for a certain vocabulary can be grasped as concepts related to tasks using vision. In a book or a text display on a computer display, such a function is exhibited.

It is generally difficult to realize such a unique function of visual information by auditory information. That is,
Since the auditory information exists only temporarily and has the property of sequentially changing, it is not possible to "look over the entire body at a certain point in time" which is possible with visual information. Therefore, in order to know the entirety based on only the auditory information, it is necessary to reproduce and hear the auditory information from the beginning to the end.

[0010] Further, since past information is lost in auditory information, backward reference which can be easily performed cannot be performed in visual information. Similarly,
It is also not possible to do a forward reference.

Therefore, obtaining information by hearing auditory information is slower than transmitting information by reading visual information such as a text display, and has a limitation in a reference range and a reference speed. Conceivable.

In view of the above situation, the present invention overcomes the limitations inherent in the transmission speed and reference range of the auditory information while using the auditory information, and provides an abundance of information contained in the auditory information and ease of handling. It is an object of the present invention to provide an information providing device by voice that also has

[0013]

According to the present invention, there is provided an audio information providing apparatus for reading information structured using information segments and information topics which are sets of information segments. A reading unit, an information structure reproducing unit that reconstructs the information read by the information reading unit on a memory, a topic pointer that points to the address of the information topic object, and a segment pointer that points to the address of the information segment object. Pointer moving unit for indicating the address where the information segment object to be located is located, a user interface unit for allowing the user to instruct pointer movement in the pointer moving unit, and a reproduction target existing at the address indicated by the pointer moved by the pointer moving unit. Information segment The contents of the object, characterized in that it comprises an information reproducing unit that reproduces voice.

With such a configuration, by structuring information using the concept of information topics and information segments,
Similarly to a browser using visual information, it is possible to realize an information providing apparatus that can perform a search and a vocabulary search in a browser using auditory information.

Further, the information providing apparatus by voice according to the present invention provides an information structure for structuring unstructured information stored in advance by designating information topics and information segments, instead of the information reading unit. It is preferable to have a conversion part. This is because the information providing apparatus using voice according to the present invention can be realized even if the information to be provided is not structured.

Further, the present invention is characterized by software for executing the function of the information providing apparatus by voice as described above as a processing step of a computer, and more specifically, an information segment and a set of the information segment. Reading information that is structured using an information topic, reconstructing the read information in memory, a topic pointer that points to the address of the information topic object, and a segment that points to the address of the information segment object Using a pointer to indicate the address where the information segment object to be reproduced is located, a step of instructing the user to move the pointer, and specifying the address of the information segment object to be reproduced existing at the address indicated by the moved pointer. The process of playing back the contents by voice Characterized in that it is a computer-readable recording medium as a program information providing method, and such a process by voice, including and.

With such a configuration, by loading and executing the program on the computer, the information is structured using the concept of the information topic and the information segment. It is possible to realize an information providing device that can perform a search, a vocabulary search, and the like even in the browser used.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A voice information providing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a configuration diagram of the information providing apparatus using voice according to the embodiment of the present invention. In FIG.
Is an information reading unit, 22 is an information structure reproducing unit, 23 is a pointer moving unit in the information structure, 24 is an information reproducing unit, and 25 is an information DB (database) for storing structured information.
, 26 denotes a user interface unit.

First, the information reading unit 21 reads information structured in advance from the information DB 25. The structured information does not necessarily need to be stored in a database. The structuring of information is performed by the following method.

In order to structure information, two units called information topics and information segments are used. The information segment refers to each segment obtained by dividing information based on some criterion, and the information topic refers to a name given to a group of information constituted by an information segment group.

FIG. 3 shows a conceptual diagram of information structuring. In FIG. 3, a mark indicates an information topic object, and a mark indicates an information segment object. It is assumed that the segment pointers are assigned to the information segment objects in the order indicated by the arrows.

First, while a plurality of information segment objects can be associated with an information topic object, a plurality of information topic objects can also be associated with an information segment object. Therefore, for example, the information segment object a is associated with the information topic object B at the same time as the configuration information segment of the information topic object A. Further, the information segment object b is associated with the information topic object C at the same time as the configuration information segment of the information topic object B. By repeating such association, it is possible to structure information.

Each information segment object contains text information to be read out by a voice browser, together with information indicating a related information topic.

The structuring of information as described above is not limited to the fact that it must be performed in advance, but may be structured in a system after being input as general data. .

Next, the information structure reproducing unit 22 reconstructs the structure of the information read by the information reading unit 21 in the computer. Specifically, a topic list and a segment list are used. The topic list is a list of information topic objects that have been read, and has a topic pointer that points to the address of the topic object that is the latest watch target in the list. The segment list is a list of information segment objects associated with each information topic, and has a segment pointer that points to the latest segment object that is to be watched.

FIG. 4 is a conceptual explanatory diagram of the topic list and the segment list. FIG. 4 shows an example in which information on two topics is reproduced.

In FIG. 4, first, the information topic 41 is read, and then the information topic 42 related to the information segment A included in the information topic 41 is read. Therefore, in this case, the information segment A to be watched by the user can be represented using the topic pointer in the topic list and the segment pointer in the segment list. That is, the information segment A is represented as an information segment indicated by the segment pointer 3 belonging to the information topic indicated by the topic pointer 10.

When the user changes the gaze target, it is sufficient to change the topic pointer and the segment pointer. That is, when changing (moving) the gazing target to the information segment B in FIG. 4, the gazing target can be moved in the structure by setting the topic pointer to 11 and the segment pointer to 0. .

Here, _assuming that the time at which the information segment A is to be watched is T _m and the time at which the information segment B is to be watched is T _n , the pointer position and the segment of the topic list at each time are shown. The pointer positions of the list are as shown in FIG.

FIG. 5A is a diagram showing a change in the pointer position of the topic list. In FIG. 5A, at the time _Tm , the pointer moves to the information topic object 4
It can be seen that at time T _n , it points to address 11 of the information topic object 42, whereas it points to address 10.

FIG. 5B is a diagram showing a change in the position of the pointer in the segment list of the information topic object 41. In FIG. 5B, at time T _m
It can be seen that the pointer of the segment list points to the address 3 of the information segment A even when the time is T _n . Similarly, information topic object 4
5C, which is a diagram showing a change in the pointer position in the segment list included in No. 2, it can be seen that at time T _n , the pointer of the segment list points to address 0 (zero) of information segment B. . Note that the information topic object 42 until the time T _n is reached.
And its segment list has not been generated.

The intra-structure pointer moving section 23 provides a means for moving the information segment pointer described above. Pointer movement in structured information is roughly classified into movement within the same information topic and movement between different information topics.

FIG. 6 shows a conceptual diagram of the movement of the pointer in the information structure. Also in FIG. 6, similarly to FIG. 3, the mark ● indicates an information topic object, and the mark ○ indicates an information segment object. It is assumed that the segment pointers are assigned to the information segment objects in the order indicated by the arrows.

In FIG. 6, movement within the same information topic means that, for example, the pointer pointing to the information segment object 61 moves to the information segment object 62.

On the other hand, movement between different information topics
For example, this means that the pointer pointing to the information segment object 61 moves to the information segment object 63.

In order to facilitate such movement, a virtual command selector is used to select an information segment to be watched. FIG. 7 is a conceptual diagram of the virtual command selector.
Shown in The virtual command selector does not directly operate the user, but selects a command through some input medium. For example, the operation command of the voice browser is determined by the virtual command selector through keyboard input, mouse input, voice recognition by voice input, or the like. Such an input is performed through the user interface unit 26.

FIG. 8 shows a general example of a virtual command selector. FIG. 8A is a conceptual diagram of the virtual command selector, and five types of commands can be selected as shown in FIGS. 8B to 8F. For example, by assigning the operation of the voice browser to each virtual command selector as shown in (Table 1), the user can reach any information segment object.

[0038]

[Table 1]

That is, the movement between the information topics is controlled by FIGS. 8B and 8D, and FIG. 8C and FIG.
(E) is set so that movement between segments can be controlled.

FIG. 9 shows a processing flow chart of the operation part of the virtual command selector. In FIG. 9, first, in a state where the virtual command selector is executable, the standby state is set until there is some input from the user interface unit 26 (step S92: No). Then, when a valid command is input (step S92: Ye
s, step S93: Yes), it is determined whether or not the operation of the voice browser specified as shown in (Table 1) is actually possible (step S94), and if the operation is possible (step S94)
95: Yes) The pointer is moved according to the command.

If the operation of the voice browser is impossible (step S95: No), it is necessary to perform error processing according to the situation. The following cases can be considered as specific examples of the case where the operation of the voice browser is impossible.

One possibility is that a command "return by one topic" is issued even though the information topic object is the root object that was read first. In this case, it is possible to cope by returning to the head of the information topic and starting reproduction. This is because the topic object may be being reproduced.

It is also conceivable that a command "go one topic forward" is issued even though the information topic object is at the end of the topic list. This case can be dealt with by terminating the processing itself.

On the other hand, the same processing can be performed on a segment. That is, when the command “return by one segment” is issued even though the information segment object to be watched is at the top of the segment list, the process returns to the top of the information segment object and starts reproduction. Although it is also possible to perform processing for reproducing the last information segment object belonging to the information topic immediately before the information topic to which the information segment belongs.

Further, when the command of "going forward by one segment" is issued even though the information segment object to be watched is at the end of the segment list, the processing of the information segment object is terminated. Although it is also possible to perform processing for reproducing a leading information segment object belonging to the information topic next to the information topic to which the information segment belongs.

Further, there may be a case where the information segment object to be watched has no related information topic object or a case where it does not have information to be reproduced. In this case, it is necessary to perform an alerting process for reproducing the fact that reproduction is impossible by using a synthetic voice or the like.

When the operation of the voice browser is possible, the following processing is performed. First, for movement within the same information topic, it is sufficient to move only the pointer of the segment list of the information topic. On the other hand, movement between different information topics is roughly classified into two types of operations.

One is movement to an information segment belonging to an information topic associated with the information segment to be watched. This is the information segment b in FIG.
Is moved to the information segment c belonging to the information topic C.

In this case, first, the topic pointer is moved so as to point to the information topic object associated with the information segment object to be watched.

If the information topic object does not exist in the topic list, the information topic object is generated before the topic pointer is moved and added to the topic list. Then, topic pointer information indicating the information topic object to which the information segment object to be watched belongs is added to the information topic object.

Further, if the newly generated information topic object does not have a segment list, a segment list is generated, and an information segment object group belonging to the information topic is registered. The movement is completed by setting a segment pointer on the newly generated information topic. The position of the new segment pointer is usually the head of the segment pointer group.

Another method is to move to an information segment in which the information topic to which the information segment to be watched belongs is the associated information topic. This corresponds to the case where the information segment b is moved to the information segment a belonging to the information topic A in FIG.

In this case, first, the topic pointer is moved so that the information topic to which the information segment object to be watched belongs belongs to the information topic object to which the information segment to be associated belongs.

Next, in the segment list of the information topic object pointed to by the moved topic pointer, the information segment that has been watched before the movement of the topic pointer points to the information segment that is the associated information segment. Move the segment pointer. Further, after the topic pointer is moved, it is also possible to delete the information topic object pointed before the movement, the segment list of the information object, and the information segment object group registered in the segment list.

The information reproducing unit 24 reproduces information such as text included in the indicated information segment object by voice. Therefore, in the case where the information segment objects are successively selected by the information structure pointer moving unit 23, the information of the corresponding information segment object is reproduced by the sound in the information reproducing unit 24 each time. It can function as a voice browser.

The information of the corresponding information segment object is generally text data, but is not particularly limited as long as the information can be read out by voice. Therefore, the audio data itself, for example, a WAV file or the like may be used.

As described above, according to the present embodiment, despite the fact that the system is based on auditory information, the concept of information topics and information segments is used.
It is possible to quickly and accurately reach information targeted for audio browsing.

Next, an apparatus for providing information by voice according to one embodiment of the present invention will be described with reference to the drawings.
FIG. 10 is a configuration diagram of a voice information providing apparatus according to an embodiment of the present invention. 10, reference numeral 101 denotes a structured information reading unit, 102 denotes an information structure reproducing unit, 103 denotes a virtual command selecting unit, 104 denotes a pointer moving unit, and 10 denotes a pointer moving unit.
Reference numeral 5 denotes an information reproducing unit.

In FIG. 10, first, the structured information reading unit 101
In, it is necessary to read structured information created in advance. Then, the information structured by the information structure reproducing unit 102 is reproduced in the system. FIG. 11 shows an example of reproducing the structured information. In the example of FIG. 11, the information topic is “navigation service”, and the related information segments are “news channel”,
A “sports channel” and a “weather forecast channel” exist. Text data corresponding to each information segment is stored in each specified text file.

Next, an instruction is input using the numeric keypad on the keyboard as a user interface. FIG. 12 shows the relationship between each key of the numeric keypad and the virtual command selector. Further, the virtual command selection unit 103 selects a command to be executed based on the key information input by the user. In the present embodiment, virtual command selectors as shown in FIG. 12 are respectively associated with '8', '6', '2', '4', and '5' on the numeric keypad.

The assignment of keys to actual commands by each virtual command selector is as shown in (Table 2). It should be noted that, for the keys '6' and '4', once selected, the operation of selecting the virtual command selector can be repeatedly performed. By doing so, the same operation as turning a page based on visual information can be performed in a voice browser.

[0062]

[Table 2]

That is, as shown in FIG. 13, the relationship between the information topic, the information segment and each pointer is established, and it is possible to perform an operation such that the segment pointer skips on the segment list by the user's keyboard input. It becomes.

Then, in the pointer moving unit 104,
The virtual command selected by the virtual command selection unit 103 is executed to move the segment pointer. First, in the case of movement within the same information topic, FIG.
In the virtual command selector shown in "
"Reproduction" is selected, and only the segment pointer is moved as shown in FIG. In this case, the topic pointer does not move.

On the other hand, since the related topic is described in the third information segment object in FIG.
When the information segment object is in the activated state, that is, when the user is watching, the generation of a new information topic and an information segment group and the movement between the information topics are performed as shown in FIG.

First, by using the virtual command selector shown in FIG. 15A, "advance one segment, play" is selected, the movement in FIG. 15C is performed within the same segment list, and then, FIG. By selecting "go forward one topic" with the virtual command selector shown in (1), an information topic related to the third information segment is generated,
The segment pointer is moved to the head segment of the new information topic. In this case, the topic pointer also moves between information topics, as shown in the movement in FIG.

When returning from the new information topic to the original information topic, as shown in FIG. 16, the newly generated information topic object and the related information segment object group are deleted.

That is, by selecting “return by one topic” with the virtual command selector shown in FIG.
The information segment indicated by the original information topic pointer and the information segment pointer shown in (b) is indicated as the information segment to be watched.

As described above, according to this embodiment, the topic pointer and the segment pointer can be controlled by the keyboard input according to the user's intention, which is similar to the browsing or the skimming in a system using visual information. The operation can also be performed with a voice browser.

Further, as another embodiment, it is conceivable to use the present invention for an operation system by voice input instead of keyboard input or the like. That is, the virtual command selector is adapted to the voice input by using the voice recognition technology together.

Specifically, an electronic mail system by voice is conceivable. Starting from the destination of the e-mail, the contents of the e-mail are input by voice, and a voice browser is used to confirm the transmission contents before transmission. As a result, the user can exchange e-mails only by telephone without having a portable terminal with a keyboard or a portable terminal capable of handwriting input. Further, it is possible to increase the speed and efficiency of listening to the received electronic mail.

Alternatively, a car navigation system by voice operation or the like can be considered. In this case, it is possible to instruct by voice input such as scrolling the screen and searching for a destination without manually inputting the information, and to transmit information necessary for the driver during driving such as the distance and time to the destination. It can be obtained by a browser and can be operated without turning the line of sight from the front of the vehicle, which can contribute to improvement of safety.

Note that the present invention is not limited to the above-described embodiment, but uses the auditory information to secure the same ease of use as the system utilizing the visual information, and furthermore, the convenience of the auditory information. The system is not limited as long as the system has both functions.

Next, a description will be given of a processing flow of a program for realizing the information providing apparatus by voice according to the embodiment of the present invention. FIG. 17 shows a flow chart of processing of a program for realizing the information providing apparatus by voice according to the embodiment of the present invention.

In FIG. 17, first, structured information is read (step S171), and the read information structure is expanded on a memory in the computer (step S17).
2). Then, an input from the user interface unit is waited.

Next, when a pointer movement instruction is input from the user interface unit (step S173),
It is determined whether the input instruction is appropriate (step S1).
74) If the input is improper, error processing is performed, and the process returns to the input waiting state.

If the input instruction is appropriate, the pointer is moved in accordance with the instruction (step S175), and the content of the information segment object pointed to by the pointer is read out and reproduced through a synthetic voice or the like (step S17).
6). Then, when the operation is further continued (step S177: No), the process returns to the input waiting state.

The recording medium storing the program for realizing the audio information providing apparatus according to the embodiment of the present invention is a CD medium as shown in the example of the recording medium shown in FIG.
-Not only a portable recording medium such as a ROM 182-1 and a floppy disk 182-2, but also any other storage device 181 provided at the end of a communication line, or a recording medium such as a hard disk or a RAM of a computer may be used. At execution, the program is loaded and executed on main memory.

Further, a recording medium on which an information topic list or the like generated by the information providing apparatus by voice according to the embodiment of the present invention is recorded is also a CD-ROM 182- as shown in the example of the recording medium shown in FIG. 1 or a floppy disk 182-2, or any other storage device provided at the end of the communication line, or a recording medium such as a computer hard disk or RAM.
For example, it is read by a computer when using the information providing apparatus by voice according to the present invention.

[0080]

As described above, according to the information providing apparatus using speech according to the present invention, the subject of speech browsing is achieved by using the concept of information topic and information segment, despite the fact that speech data is handled. Can be quickly and accurately reached, and it is possible to enjoy the advantages inherent in visual information, such as searching (reading) and searching for vocabulary.
