DIALOGUE MODELS FOR VEHICLE OCCUPANTS
First Claim
1. A method for operating a device to conduct a dialogue with a human dialogue participant in an environment, the method comprising:
- obtaining a parameter related to at least one feature selected from a group consisting of;
a feature of the dialogue participant; and
a feature of the environment;
selecting a specific dialogue model from a plurality of dialogue models, such that the specific dialogue model is associated with the parameter;
generating, by the device, at least one output dialogue action based on the specific dialogue model; and
presenting, by the device, the at least one output dialogue action to the human dialogue participant.

Abstract
Methods and apparatus for creating and managing multiple dialogue models in a statistical dialogue modeling system capable of learning, and conducting human-machine dialogues based on selected models. Dialogue models are selected according to feature vectors that describe characteristics of the dialogue participants and their current situation. Mobile apparatus in motor vehicles can provide optimized dialogue service to occupants of the motor vehicles according to vehicle location and route, in addition to personal characteristics of the occupants, whether driver or passenger. When networked via a remote dialogue server, a large pool of dialogue participants is available for automatic building of dialogue models suitable for handling a variety of situations and participants.

12. A system for choosing a selected dialogue model and for creating and managing a dialogue based on the selected dialogue model, the system comprising:
-
a speech generation unit; a dialogue model set storage; a dialogue control unit, for sending a dialogue act to the speech generation unit; a cluster determination unit, for determining a cluster ID associated with the dialogue; and a dialogue model selection unit for choosing a selected dialogue model from the dialogue model set storage according to the cluster ID, and for sending the selected dialogue model to the dialogue control unit; wherein the dialogue control unit sends the dialogue act to the speech generation unit based on the selected dialogue model. - View Dependent Claims (13, 14, 15)
