## Abstract

A response system includes: a content reproduction unit that reproduces a content; a microphone; an input voice recognition unit that recognizes an input voice to the microphone; and a response generation unit that generates a response sentence to the input voice based on the input voice and the content which is reproduced by the content reproduction unit before an input time point of the input voice to the microphone.

## Claims

### Claim 1

A response system comprising:
a content reproduction unit that reproduces a content;
a microphone;
an input voice recognition unit that recognizes an input voice to the microphone; and
a response generation unit that generates a response sentence to the input voice based on the input voice and the content which is reproduced by the content reproduction unit before an input time point of the input voice to the microphone.

### Claim 2 (depends on 1)

The response system according to claim 1, wherein
the response generation unit
determines whether or not the content which is reproduced by the content reproduction unit before the input time point of the input voice to the microphone is a related content which is related to the input voice and generates the response sentence based on the input voice and the related content in a case where the content reproduced by the content reproduction unit is the related content.

### Claim 3 (depends on 2)

The response system according to claim 2, wherein
the response generation unit
determines whether or not the content is the related content while setting, as a target, a content which is reproduced by the content reproduction unit after a time point a predetermined time period before a time point at which the input voice is input to the microphone or while setting, as targets, sentences in a predetermined position and subsequent positions in order from a last position in a case where the content reproduction unit reproduces the content including a plurality of sentences.

### Claim 4 (depends on 1)

The response system according to claim 1, wherein
the response generation unit
determines whether or not the content which is reproduced by the content reproduction unit before the input time point of the input voice to the microphone is a related content which is related to the input voice and generates the response sentence based on the input voice in a case where the content reproduced by the content reproduction unit is not the related content.

### Claim 5 (depends on 2)

The response system according to claim 2, wherein
the response generation unit
generates the response sentence based on the input voice and a sentence, which is reproduced by the content reproduction unit at a time point closest to the input time point of the input voice, among a plurality of sentences in a case where the content, which is reproduced by the content reproduction unit before the input time point of the input voice to the microphone, includes the plurality of sentences which are related to the input voice.

### Claim 6 (depends on 2)

The response system according to claim 2, wherein
in a case where a plurality of the input voices to the microphone are recognized by the input voice recognition unit,
the response generation unit
generates the response sentence common to the plurality of input voices based on the plurality of input voices and the content in a case where a similarity degree of the plurality of input voices is equal to or higher than a predetermined value and
individually generates the response sentence for each of the plurality of input voices based on the input voice and the content in a case where the similarity degree of the plurality of input voices is lower than the predetermined value.

### Claim 7

A response method comprising:
reproducing a content by a content reproduction unit;
recognizing an input voice to a microphone by an input voice recognition unit; and
generating, by a response generation unit, a response sentence to the input voice based on the input voice and the content which is reproduced by the content reproduction unit before an input time point of the input voice to the microphone.
