A topic-driven active conversation robot for accompanying of old people

Abstract

The invention relates to a topic-driven active conversation robot for accompanying of old people. The system comprises a voice input subsystem which is used for collecting voice input information of the elderly and transmitting the voice input information to a dialogue processing system; a dialogue processing system which is used for processing the voice input information and outputting corresponding voice output information to the voice output subsystem; And a voice output subsystem which is used for outputting the voice output information. Through the function of the dialogue processing system, a conversation can be actively tried to be started, and the utilization rate is greatly increased; Topics can be intelligently selected, old people are attracted to continuously talk, and the conversation amount is increased; A new topic can be explored, searched and found in a conversation record, and a personalized topic library is expanded; The conversation state can be dynamically monitored, and conversation can be controlled in real time; Short-term and long-term memories for conversations can be acquired; Response content can be filtered, and taboos and sensitive topics are avoided.

Description

technical field [0001] The invention relates to a topic-driven active dialogue robot for accompanying the elderly. Background technique [0002] Traditionally, there are two main types of dialogue robots on the market in terms of function: [0003] 1. Commercial dialogue robots: mainly used for providing information content services such as customer service, product introduction, and knowledge provision; [0004] 2. Entertainment dialogue robot: Provide entertainment and recreation services to users mainly through question-and-answer methods. [0005] According to the technical implementation method, there are also two categories: [0006] 1. Rule-based dialogue robot: According to the user's dialogue input content, in the pre-set response set, select an answer according to specific rules; commercial dialogue robots are usually based on a specific knowledge base; [0007] 2. Dynamic response generation robot: usually uses artificial intelligence technology such as machine...

[0014] 2. The topic of the conversation must be determined and initiated by the conversation partner. When the conversation partner does not have a clear topic, it will be deadlocked and the conversation cannot be continued effectively; this is very unfavorable for long-term use;

[0015] 3. Existing chatbots either use prefabricated answers based on rules (which can guarantee the safety of answers, but lack the unique fun of immediacy, which makes it difficult to motivate the elderly to continue), or temporarily generate answers (which can achieve immediacy, but may be out of touch). the older person’s range of interests and produce unsafe responses); unable to strike a good balance between effective responses (that motivate the older person to continue the conversation) and safe responses (being interested and avoiding taboo and sensitive topics)

[0019] At present, there are very few domestic researches in the field of dialogue control, and it can even be said to be a blank; especially how to monitor the current dialogue state and drive the next dialogue process according to the dialogue state
