Acquisition method, generation method, system therefor and program

3:

• An acquisition method executed by an acquisition system to acquire a speech set in which N speeches are associated with one another where N is assumed to be any one of an integer equal to or greater than 3, used to generate an N-th speech made by a dialog system in response to an (N−1)-th human speech made after first to (N−2)-th speeches made by the dialog system or/and a human based on a speech set in which N speeches are associated with one another, a storage part of the acquisition system storing a speech set including N−1 speeches associated with one another, the acquisition method comprising:
• a presentation step of presenting in order, a speech t(1) to a speech t(N−1) which are N−1 consecutive speeches included in a certain speech set stored in the storage part of the acquisition system;
• a speech receiving step of receiving input of an N-th speech t(N) which is a human speech after presenting the speech t(N−1) which is an (N−1)-th speech;
• and
• a storing step of storing a speech t(N−mp+1) to the speech t(N) associated with one another for each mp as a speech set in which mp speeches are associated with one another in the storage part of the acquisition system, where p is assumed to be an integer equal to or greater than 1 and equal to or less than P and each mp is assumed to be any one of an integer equal to or greater than 2 and equal to or less than N.

5:

• A generation method for a generation system to generate a speech made by a dialog system in response to a human speech, a storage part of the dialog system storing a speech set in which a first speech presented by an acquisition system, a second speech presented by the acquisition system and a third speech which is a speech of a person a made after presenting the second speech are associated with one another, the generation method comprising:
• a presentation step of presenting a speech t(1) stored in the storage part of the dialog system;
• a speech receiving step of receiving input of a second speech t′(2) which is a speech of a person b after presenting the speech t(1);
• and
• generation step of generating a third speech of a speech set in which a first speech is identical or similar to the speech t′(1) and a second speech is identical or similar to the speech t′(2) of the speech set stored in the storage part of the dialog system as a speech of the dialog system after the speech t′(2).

6:

• A generation method for a generation system to generate a speech made by a dialog system in response to a human speech, a storage part of the dialog system storing a speech set in which a first speech to an (N−1)-th speech where N is assumed to be any one of an integer equal to or greater than 3, made between a person a and an acquisition system and an N-th speech which is a speech of the person a made after the (N−1)-th speech are associated with one another, the generation method comprising:
• a speech receiving step of receiving input of an m-th speech t′(m) which is a speech of a person b where m is assumed to be any one of an integer equal to or greater than 2 and less than N;
• and
• a generation step of generating at least a speech t(N−j+1) where j is assumed to be any one of an integer equal to or greater than 1 and equal to or less than N−m, of speeches following an m consecutive speech t(N−m+1−j) to speech t(N−j) of a speech set in which the m consecutive speech t(N−m+1−j) to speech t(N−j) included in the speech set among the speech sets stored in the storage part of the dialog system are identical or similar to a first speech t′(1) to an m-th speech t′(m) made between the person b and the dialog system, as a speech of the dialog system after the speech t′(m).

7:

• An acquisition system that acquires a speech set in which three speeches are associated with one another used to generate a second speech made by a dialog system in response to a human speech made in response to a first speech made by the dialog system based on a speech set in which three speeches are associated with one another, the acquisition system comprising:
• a storage part that stores a plurality of speech sets in which two speeches are associated with each other;
• a presentation part that presents in order, a speech t(1) and a speech t(2) which are two consecutive speeches included in a certain speech set stored in the storage part;
• and
• a speech receiving part that receives input of a third speech t(3) which is a human speech after presenting the speech t(2), wherein
• the storage part stores the speech t(1), the speech t(2) and the speech t(3) associated with one another as a speech set in which three speeches are associated with one another.

8:

• An acquisition system to acquire a speech set in which N speeches are associated with one another where N is assumed to be any one of an integer equal to or greater than 3, used to generate an N-th speech, made by a dialog system in response to an (N−1)-th human speech made after first to (N−2)-th speeches made by the dialog system or/and a human based on a speech set in which N speeches are associated with one another, the acquisition system comprising:
• a storage part that stores a speech set in which N−1 speeches are associated with one another;
• a presentation part that presents in order, a speech t(1) to a speech t(N−1) which are N−1 consecutive speeches included in a certain speech set stored in the storage part of the acquisition system;
• and
• a speech receiving part that receives input of an N-th speech t(N) which is a human speech after presenting the speech t(N−1) which is an (N−1)-th speech, wherein
• a speech t(N−mp+1) to the speech t(N) associated with one another are stored for each mp as a speech set in which mp speeches are associated with one another in the storage part, where p is assumed to be an integer equal to or greater than 1 and equal to or less than P and each mp is assumed to be any one of an integer equal to or greater than 2 and equal to or less than N.

9:

• A generation system that generates a speech made by a dialog system in response to a human speech, the generation system comprising:
• a storage part that stores a speech set in which a first speech presented by an acquisition system, a second speech presented by the acquisition system and a third speech which is a speech of a person a made after presenting the second speech are associated with one another;
• a presentation part that presents a speech t′(1) stored in the storage part of the dialog system;
• a speech receiving part that receives input of a second speech t′(2) which is a speech of a person b after presenting the speech t(1);
• and
• a generation part that generates a third speech of a speech set in which a first speech is identical or similar to the speech t′(1) and a second speech is identical or similar to the speech t′(2) of the speech set stored in the storage part of the dialog system as a speech of the dialog system after the speech t′(2).

10:

• A generation system that generates a speech made by a dialog system in response to a human speech, the generation system comprising:
• a storage part that stores a speech set in which a first speech to an (N−1)-th speech made between a person a and an acquisition system and an N-th speech which is a speech of a person a made after the (N−1)-th speech are associated with one another, where N is assumed to be any one of an integer equal to or greater than 3;
• a speech receiving part that receives input of an m-th speech t′(m) which is a speech of a person b where m is assumed to be any one of an integer equal to or greater than 2 and less than N;
• and
• a generation part that generates at least a speech t(N−j+1) where j is assumed to be any one of an integer equal to or greater than 1 and equal to or less than N−m, of speeches following an m consecutive speech t(N−m+1−j) to speech t(N−j) of a speech set in which the m consecutive speech t(N−m+1−j) to speech t(N−j) included in the speech set among the speech sets stored in the storage part of the dialog system are identical or similar to a first speech t′(1) to an m-th speech t′(m) made between the person b and the dialog system, as a speech of the dialog system after the speech t′(m).
