Abstract

A voice search apparatus includes a web page display controller, a voice recognizer, a matching unit, and a URL creator. The web page display controller controls a web page which is to be displayed on a display. The voice recognizer recognizes a voice that is input, converts the voice into character string information, and outputs the character string information. The matching unit refers to a URL list in which a character string representing part of a URL is registered for each search category, performs matching processing between a URL of the web page displayed on the display and the character string in the URL list, and specifies the character string in the URL list corresponding to the URL. The URL creator creates a URL based on the character string specified by the matching unit and the character string information.

Claims

1. A voice search apparatus comprising:

a web page display controller that controls a web page which is to be displayed on a display;

a voice processor that receives voice information from a voice that is input, determines if a preset reserved word is included in the voice information, and outputs reserved word information including an attribute of the reserved word;

a voice recognizer that converts the voice information into character string information, and outputs the character string information;

a storage that stores a URL list in which a character string representing part of a URL is registered for a search category;

a processor including a matching unit that refers to the URL list, performs matching processing between a first URL of the web page displayed on the display and the character string in the URL list, and specifies the character string in the URL list corresponding to the first URL; and

a URL creator that creates a second URL based on the character string specified by the matching unit and the character string information,

wherein the processor determines whether or not the reserved word information is included in the character string information,

wherein the URL creator creates the second URL based on the character string specified by the matching unit and the character string information when the processor determines that the reserved word information is not included in the character string information,

wherein the URL creator creates a third URL based on the URL list registered for the search category relevant to the reserved word information and the character string information except the reserved word information when the processor determines that the reserved word information is included in the character string information, and

wherein the web page display controller displays the web page, relevant to the second URL or the third URL created by the URL creator, on the display.

2. A voice search method comprising:

displaying a web page on a display;

recognizing a voice that is input and converting the voice into character string information; and

when an information relevant to a search category is not included in the character string information, referring to a URL list in which a character string representing part of a URL is registered for the search category, performing matching processing between a first URL of the web page displayed on the display and the character string in the URL list, and specifying the character string in the URL list corresponding to the first URL via a processor, and

creating a second URL based on the specified character string and the character string information,

when the information relevant to the search category is included in the character string information, creating a third URL based on the URL list registered for the search category and the character string information except the information relevant to the search category, and

displaying the web page, relevant to the second URL or the third URL, on the display.

3. A display apparatus comprising:

a display;

a web page display controller that controls a web page which is to be displayed on the display;

a voice processor that receives voice information from a voice that is input, determines if a preset reserved word is included in the voice information, and outputs reserved word information including an attribute of the reserved word;

a voice recognizer that converts the voice information into character string information, and outputs the character string information;

a storage that stores a URL list in which a character string representing part of a URL is registered for a search category;

a processor including a matching unit that refers to the URL list, performs matching processing between a first URL of the web page displayed on the display and the character string in the URL list, and specifies the character string in the URL list corresponding to the first URL; and

a URL creator that creates a second URL based on the character string specified by the matching unit and the character string information,

wherein the processor determines whether or not the reserved word information is included in the character string information,

wherein the URL creator creates the second URL based on the character string specified by the matching unit and the character string information when the processor determines that the reserved word information is not included in the character string information,

wherein the URL creator creates a third URL based on the URL list registered for the search category relevant to the reserved word information and the character string information except the reserved word information when the processor determines that the reserved word information is included in the character string information, and

wherein the web page display controller displays the web page, relevant to the second URL or the third URL created by the URL creator, on the display.
