Classification: CPC G | IPC G

Claim 0:
1. A voice interaction method, comprising:
detecting a target event that can trigger a voice interaction;
querying, based on the target event, a mapping relationship to obtain a service type set and a first probability corresponding to a first target service type, wherein the first probability indicates a possibility of executing a first service corresponding to the first target service type;
collecting a voice instruction comprising semantic information;
obtaining, based on the semantic information, a second service corresponding to the semantic information;
executing the second service according to the voice instruction when a first service type of the second service is the first target service type;
filtering out, from the service type set, a second target service type comprising a second probability that does not meet a probability threshold before executing the second service and when the first service type is the first target service type;
updating, based on the semantic information, a third probability in the mapping relationship;
increasing a fourth probability corresponding to the first service type in the mapping relationship when the first service type is the first target service type;
decreasing the first probability when the first service type is different from the first target service type; and
increasing the fourth probability when the semantic information comprises a wakeup word.
