Abstract

An information system includes an output section to read a character string in received contents aloud, and a memory section to store a rule set to convert input contents to modified contents adapted to text reading. An optimizing section is arranged to covert the input contents to the modified contents according to the rule set, and to cause the output section to read out the modified contents.

Claims

1. An information system comprising:

an output section to read out a character string in received contents;

a memory section to store a rule set to convert input contents to modified contents adapted to text reading; and

an optimizing section to covert the input contents to the modified contents according to the rule set, and to cause the output section to read out the modified contents.

2. The information system as claimed in claim 1, wherein the memory section includes a rule memory section to store a character string replacement rule group to replace an input character string in the input contents with a modified character string for the modified contents;

and the optimizing section includes a character string replacing section to replace the input character string in the input contents with the modified character string for the modified contents according to the character string replacement rule group, and to cause the output section to read out the modified character string.

3. The information system as claimed in claim 1, wherein the memory section includes a rule memory section to store a format conversion rule group to convert an input format in the input contents to a modified format for the modified contents;

and the optimizing section includes a character string format converting section to convert the input format in the input contents to the modified format for the modified contents according to the format conversion rule group, and to cause the output section to read out the modified contents in the modified format.

4. The information system as claimed in claim 1, wherein the information system further comprises a category discriminating section to discriminate a category of the input contents;

the memory section comprises an optimization information memory section to store optimization information including information on rules selected from the rule set in dependence on the category, and an order of application of the rules selected from the rule set; and

the optimizing section is configured to covert the input contents to the modified contents according to rules selected from the rule set in dependence on the category of the input contents by using the optimization information stored in the optimization information memory section.

5. The information system as claimed in claim 1, wherein the output section is mounted on a vehicle.

6. The information system as claimed in claim 5, wherein the information system comprises a center system which includes the memory section;

the optimizing section; and

a transmitting section to transmit the modified contents to vehicles each equipped with the output section.

7. An information supplying process comprising:

receiving input contents;

converting the input contents to modified contents adapted to text reading automatically according to a preliminarily stored rule set; and

supplying the modified contents to speak the modified contents aloud.

8. The information supplying process as claimed in claim 7, wherein the information supplying process further comprises:

identifying a category of the input contents; and

selecting rules from the rule sets in accordance with the category, for use for converting the input contents to the modified contents.

9. The information supplying process as claimed in claim 7, wherein the modified contents is supplied to speak the modified contents aloud by transmitting the modified contents to remote terminals.

10. An information system comprising:

means for storing a rule set to convert input contents to modified contents adapted to text reading;

means for converting the input contents to the modified contents according to the rule set; and

means for supplying the modified contents to speak the modified contents aloud.
