Abstract

An integrated dialogue system is provided. The system comprises a bridge and a plurality of domains, wherein all domains are coupled to the bridge with bidirectional communications. A domain database is optional to the domains. After receiving an input data, the domain recognizes the input data and determines whether to process the input data by itself, or to process the input data in the domain and transmit a dialogue result and the input data to another domain, or transmit the input data to another domain without processing.

16. The integrated dialogue system of claim 14, wherein the voice recognition module further comprises:

at least one other-domain lexicon, for determining lexicon-relationship between the voice input data and other domains; and

at least one other-domain grammar database, for determining grammar-relationship between the text input data or the recognized voice data and other domains.

17. An integrated dialogue method for a bridge and a plurality of domains, wherein the bridge is coupled to each of the domains with a bidirectional communication, the integrated dialogue method comprising:

when a first domain in the domains receives and recognizes an input data, the first domain determines whether to process the input data by itself or to transmit the input data to a second domain in the domains via the bridge.

18. The integrated dialogue method of claim 17, after the input data is recognized, further comprises:

determining whether to process the input data in the first domain, or to generate a dialogue result after process and transmit the dialogue result to the second domain, or to transmit the input data to the second domain without processing.

19. The integrated dialogue method of claim 17, further comprising a step of obtaining a local domain dialogue command and/or a dialogue parameter information by recognizing the input data and generating dialogue history information.
