System and method for conversational agent via adaptive caching of dialogue tree

Abstract

The present teaching relates to method, system, medium, and implementations for managing a user machine dialogue. Sensor data is received at a device, including an utterance representing a speech of a user engaged in a dialogue with the device. The speech of the user is determined based on the utterance and a response to the user is searched by a local dialogue manager residing on the device against a sub-dialogue tree stored on the device. The response, if identified from the sub-dialogue tree, is rendered to the user in response to the speech. A request is sent to a server for the response, if the response is not available in the sub-dialogue tree.

We claim: 
     
         1 . A method implemented on at least one machine including at least one processor, memory, and communication platform capable of connecting to a network for managing a user machine dialogue, the method comprising:
 receiving, at a device, sensor data including an utterance representing a speech of a user engaged in a dialogue with the device;   determining the speech of the user based on the utterance;   searching, by a local dialogue manager residing on the device, a sub-dialogue tree stored on the device for a response to the user based on the speech;   rendering the response to the user in response to the speech, if the response is identified from the sub-dialogue tree; and   sending, if the response is not available in the sub-dialogue tree, a request to a server for the response.
