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.
