Abstract: PROBLEM TO BE SOLVED: To permit an accurate speech recognition communication between a portable sound signal preprocessor(SSP) device and an automatic speech/ speaker recognition(ASSR) by converting feature vector data produced from digital signals into acoustic signals and communicating through a communication channel. SOLUTION: A ciphering device 130 ciphers data preprocessed by a digital signal processor(DSP) 120, and guarantees a safe exchange of the signals through a telephone line. A compression device 140 compresses the preprocessed data before transfer, and increases the data in the quantity forwarded and transmitted by audio signals when a band width of the line is narrow. And, the preprocessing of digitized data from a microphone 10 generates a sequence of a feature vector representing a speech pattern spoken to the microphone 100. Further, a receiver part of an acoustic coupler 150 converts audio signals from an ear pad of the receiver into digital signals to process them with DSP 120.

Abstract: PROBLEM TO BE SOLVED: To provide a both initiative multi-modal dialogue for using in a dialogue system, declarative type programming relevant to natural language understanding, preparation technique for an application using other programming and other information browsing mechanism relevant to it. SOLUTION: This system comprises a step expressing a dialogue which a user can perform with a dialogue system as one data model or as a one or a plurality of user dialogue components transplanting an application condition of the data model and bound to it, so that the dialogue which the user performs with the dialogue system is a both initiative dialogue. At least a part of one or a plurality of user dialogue components can be converted to or correlated with rendering peculiar to a one or a plurality of forms in the application. The rendering can be shown to the user, and is selected or generated by a dialogue manager algorithm. COPYRIGHT: (C)2004,JPO
