Abstract

It is possible to realize a reliable audio recognition in use of dictionary data for audio recognition while reducing the data amount of the dictionary data. An information recording and reproducing apparatus RP acquires text data indicating each program title from EPG data, sets up a keyword within a range of number of characters “N” enabled to be displayed in a display column in a program list from each text data thus acquired, generates feature quantity pattern indicating feature quantity of voice corresponding to each keyword, and associates the feature quantity pattern with text data for specifying a program title to generate dictionary data. Furthermore, when displaying a program list, keyword portion is highlighted to show a user content of the keyword.

wherein the keyword in the dictionary data is set up in a range of number of characters enabled to display for displaying the keyword, and

the display control device generates the display data in the range of number of characters enabled to display and supplies it to the display apparatus.

7. The electronic apparatus according to claim 6,

wherein the display control device highlights only a character portion corresponding to the keyword, included in a string in generating display data for displaying the string including as least the keyword, being a part of the string corresponding to the command.

8. The electronic apparatus according to claim 7,

wherein the display control device highlights by at least one of the following measures in highlighting:

(a) displaying by changing color of only a keyword portion,

(b) displaying by changing font of character of the keyword portion,

(c) displaying the characters of the keyword portion in bold,

(d) displaying by changing character size of the keyword portion,

(e) displaying character of the keyword portion by surrounding with frame,

(f) displaying by blinking character of the keyword portion, or

(g) displaying by reversing character the keyword portion.

9. The electronic apparatus according to claim 7, further comprising:

the receiving device that receives electronic program list information for displaying a program list of broadcast program,

wherein the record device records content data corresponding to a command specifying the broadcast program and the dictionary data associating the feature quantity data corresponding to keyword, which is set up at a portion of a string corresponding to the program, and

the display control device causes the display apparatus display the program list on the basis of the electronic program list information thus received, and highlight a keyword portion to be uttered by a user in displaying the program list on the basis of the dictionary data.

10. The electronic apparatus according to claim 9, further comprising a content data record device that records content data corresponding to the broadcast program,
