Abstract

In an information recording system, a sound processing unit generates a conversion candidate word in a process of converting sound information into text information. A recording unit records the text information and the conversion candidate word on a recording medium such that the text information and the conversion candidate word are associated with each other. A search unit performs a search based on a keyword and extracts a word matching the keyword from words within the text information and the conversion candidate word. A reading unit reads the text information including the word matching the keyword from the recording medium. A display unit displays the text information such that a part corresponding to the word matching the keyword and a part other than the corresponding part are able to be distinguished.

First claim

What is claimed is:

1 . An information recording system comprising:
a sound acquisition unit configured to acquire sound information based on a sound uttered by a user; a sound processing unit configured to convert the sound information acquired by the sound acquisition unit into text information and generate at least one conversion candidate word corresponding to the sound in a process of converting the sound information into the text information; a recording unit configured to record the text information and the conversion candidate word such that the text information and the conversion candidate word are associated with each other; a keyword reception unit configured to receive a keyword; a search unit configured to search for the keyword received by the keyword reception unit in the text information and the conversion candidate word and extract a word matching the keyword from words within the text information and the conversion candidate word; a reading unit configured to read the text information including a first part corresponding to the word matching the keyword and a second part other than the first part from the recording medium; and a display unit configured to display the text information read by the reading unit such that the first part and the second part are able to be distinguished.

2 . An information recording system comprising:
an object information acquisition unit configured to acquire object information about an object; a sound acquisition unit configured to acquire sound information based on a sound uttered by an observer who observes the object; a sound processing unit configured to convert the sound information acquired by the sound acquisition unit into text information and generate at least one conversion candidate word corresponding to the sound in a process of converting the sound information into the text information; a recording unit configured to record the object information, the text information, the conversion candidate word, and time point information on a recording medium such that the object information, the text information, the conversion candidate word, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired and a time point at which the sound information that is a source of the text information was acquired; a keyword reception unit configured to receive a keyword; a search unit configured to search for the keyword received by the keyword reception unit in the text information and the conversion candidate word and extract a word matching the keyword from words within the text information and the conversion candidate word; a reading unit configured to read the object information associated with the time point information corresponding to the word matching the keyword from the recording medium; and a display unit configured to display the text information read by the reading unit.

3 . The information recording system according to claim 2 ,
wherein the recording unit records the object information, the sound information, the text information, the conversion candidate word, and the time point information on the recording medium such that the object information, the sound information, the text information, the conversion candidate word, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the sound information was acquired, and a time point at which the sound information that is a source of the text information was acquired, the information recording system further comprises an event detection unit configured to detect at least two events on the basis of at least one piece of the object information and the sound information recorded on the recording medium, the events being a state in which the at least one piece of the object information and the sound information recorded on the recording medium satisfies a predetermined condition, the reading unit reads at least two pieces of the object information, each of which is associated with the time point information corresponding to an event occurrence time point that is a time point at which the event occurred from the recording medium, the display unit displays the object information read by the reading unit, the search unit searches for the keyword received by the keyword reception unit in the text information and the conversion candidate word that are associated with the time point information corresponding to the event occurrence time point, and the display unit displays the object information associated with the time point information corresponding to the event occurrence time point at which the word matching the keyword was detected such that the object information is distinguished from other object information.

4 . The information recording system according to claim 2 ,
wherein the recording unit records the object information, the sound information, the text information, the conversion candidate word, and the time point information on the recording medium such that the object information, the sound information, the text information, the conversion candidate word, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the sound information was acquired, and a time point at which the sound information that is a source of the text information was acquired, the information recording system further comprises an event detection unit configured to detect at least two events on the basis of at least one piece of the object information and the sound information recorded on the recording medium, the events being a state in which the at least one piece of the object information and the sound information recorded on the recording medium satisfies a predetermined condition, the reading unit reads the object information and the text information that are associated with the time point information corresponding to an event occurrence time point that is a time point at which the event occurred from the recording medium, the display unit displays the object information and the text information read by the reading unit, the search unit searches for the keyword received by the keyword reception unit in the text information and the conversion candidate word that are associated with the time point information corresponding to the event occurrence time point, and the display unit displays the word that is within the text information and matches the keyword such that the word is distinguished from other words within the text information, and displays the word that is within the text information and is associated with the conversion candidate word matching the keyword such that the word is distinguished from other words within the text information.

5 . The information recording system according to claim 3 , wherein, when a state of the object indicated by the object information is a state predefined as an event detection condition, the event detection unit detects the event.

6 . The information recording system according to claim 4 , wherein, when a state of the object indicated by the object information is a state predefined as an event detection condition, the event detection unit detects the event.

7 . The information recording system according to claim 3 ,
wherein the sound information is a time-series sound signal, and when amplitude or power of the sound signal exceeds a threshold value predefined as an event detection condition, the event detection unit detects the event.

8 . The information
