Information processing device, information processing system, and information processing method, and program

An information processing system comprising a user terminal and a data processing server,

• wherein the user terminal includes a first central processing unit (CPU) configured to:
• receive inputs including a user utterance, and
• transmit the received inputs including the user utterance to the data processing server, and
• the data processing server includes a second CPU configured to:
• determine an utterance type of the user utterance received from the user terminal,
• generate a system response according to a type determination result associated with the determined utterance type of the user utterance,
• wherein the type determination result associated with the determined utterance type of the user utterance includes:
• a (Type A) user utterance that requests all reutterances of a system utterance immediately before the user utterance,
• a (Type B) user utterance that requests a reutterance of a part of the system utterance immediately before the user utterance, and
• a (Other type) user utterance of a task request type,
• generate a system response to reutter all system utterances immediately before the user utterance in a case where the user utterance is of the type A;
• generate a system response to reutter a part of system utterances immediately before the user utterance in a case where the user utterance is of the type B, and
• generate a system response as a result of executing a requested task of the user utterance in a case where the user utterance is of the other type,
• wherein the requested task is determined based on:
• a system utterance immediately before the user utterance, and
• a past dialog history including at least one of:
• a set of past user utterances, a set of past system responses corresponding to the set of user utterances, and a set of past execution results corresponding to the set of user utterances.

An information processing method, comprising:

• in an information processing device:
• determining an utterance type of a user utterance;
• generating a system response according to a type determination result associated with the determined utterance type of the user utterance,
• wherein the type determination result associated with the determined utterance type of the user utterance includes:
• a (Type A) user utterance that requests all reutterances of a system utterance immediately before the user utterance,
• a (Type B) user utterance that requests a reutterance of a part of the system utterance immediately before the user utterance, and
• a (Other type) user utterance of a task request type;
• generating a system response to reutter all system utterances immediately before the user utterance in a case where the user utterance is of the type A;
• generating a system response to reutter a part of system utterances immediately before the user utterance in a case where the user utterance is of the type B;
• and
• generating a system response as a result of executing a requested task of the user utterance in a case where the user utterance is of the other type,
• wherein the requested task is determined based on:
• a system utterance immediately before the user utterance, and
• a past dialog history including at least one of:
• a set of past user utterances, a set of past system responses corresponding to the set of user utterances, and a set of past execution results corresponding to the set of user utterances.

An information processing method executed in an information processing system including a user terminal and a data processing server, wherein the information processing method comprising:

• in the user terminal:
• inputting a user utterance via a voice input unit and transmitting the user utterance to the data processing server;
• and
• in the data processing server:
• determining an utterance type of the user utterance received from the user terminal;
• generating a system response according to a type determination result associated with the determined utterance type of the user utterance,
• wherein the type determination result associated with the determined utterance type of the user utterance includes:
• a (Type A) user utterance that requests all reutterances of a system utterance immediately before the user utterance,
• a (Type B) user utterance that requests a reutterance of a part of the system utterance immediately before the user utterance, and
• a (Other type) user utterance of a task request type;
• generating a system response to reutter all system utterances immediately before the user utterance in a case where the user utterance is of the type A;
• generating a system response to reutter a part of system utterances immediately before the user utterance in a case where the user utterance is of the type B;
• and
• generating a system response as a result of executing a requested task of the user utterance in a case where the user utterance is of the other type,
• wherein the requested task is determined based on:
• a system utterance immediately before the user utterance, and
• a past dialog history including at least one of:
• a set of past user utterances, a set of past system responses corresponding to the set of user utterances, and a set of past execution results corresponding to the set of user utterances.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that when executed by an information processing device causes the information processing device to execute information processing operations comprising:

• determining an utterance type of a user utterance;
• generating a system response according to a type determination result associated with the determined utterance type of the user utterance,
• wherein the type determination result associated with the determined utterance type of the user utterance includes:
• a (Type A) user utterance that requests all reutterances of a system utterance immediately before the user utterance,
• a (Type B) user utterance that requests a reutterance of a part of the system utterance immediately before the user utterance, and
• a (Other type) user utterance of a task request type;
• generating a system response to reutter all system utterances immediately before the user utterance in a case where the user utterance is of the type A
• generating a system response to reutter a part of system utterances immediately before the user utterance in a case where the user utterance is of the type B;
• and
• generating a system response as a result of executing a requested task of the user utterance in a case where the user utterance is of the other type,
• wherein the requested task is determined based on:
• a system utterance immediately before the user utterance, and
• a past dialog history including at least one of:
• a set of past user utterances, a set of past system responses corresponding to the set of user utterances, and a set of past execution results corresponding to the set of user utterances.
