Abstract: Information search system includes terminal having speech communication function and packet communication function and center for selectively performing speech communication and packet communication with the terminal. Center includes speech control section, speech recognition section, information search section, speech conversion section, and packet control section. Speech control section performs speech communication with the terminal packet communication. Speech recognition section recognizes speech signal received by speech control section and sent from the terminal. Information search section searches for information on the basis of speech information recognized by speech recognition section. Speech conversion section converts speech information of the information searched out by information search section into speech signal and outputs it to speech control section. Speech signal from speech conversion section is transmitted to the terminal by speech control section.

Abstract: To provide a speech recognition apparatus which enables the reduction of transmission time and of costs. A terminal-side apparatus (100) includes a speech detection portion (101) for detecting a speech interval of inputted data, a waveform compression portion (102) for compressing waveform data at the detected speech interval, and a waveform transmission portion (103) for producing the compressed waveform data. A server-side apparatus (200) includes a waveform reception portion (201) for receiving the waveform data transmitted from the terminal-side apparatus, a waveform decompression portion (202) for decompressing the received waveform data, an analyzing portion (203) for analyzing the decompressed waveform data, and a recognizing portion (204) for performing recognition processing to produce a recognition result.

Abstract: In this radio portable terminal communication system, a service document file is converted into a window-related document file, speech-dialog-related document file, and information sharing document file. A description of a telephone number for speech communication with a center is added to the window-related document file. The window-related document file is output to a place where the file can be used through packet communication. The speech-dialog-related document file is output to a place where the file can be referred to by a speech dialog control section (207). The information sharing document file is output to an information management section (204). The information management section (204) manages information in accordance with the general-purpose description language contents of the information sharing document file such that information can be shared between the window-related document file and the speech-dialog-related document file.

Abstract: In a voice recognition dialogue system having a plurality of recognition dialogue servers, there is no framework to select and determine one recognition dialogue server. A client 10 transmits its ability information stored in a terminal information storage 140 to a recognition dialogue selecting server 20. The ability of the client 10 includes a CODEC ability (CODEC type, CODEC compression mode, etc.), a voice data format (compressed voice data, feature vector, etc.), a recorded voice I/O function, a synthesized voice I/O function (without synthesizing engine, with intermediate representation input engine, with character string input engine, etc.), and service contents.

Abstract: An information search system includes a radio portable terminal having a speech communication function and packet communication function and a center for selectively performing speech communication and packet communication with the radio portable terminal. The center includes a speech control section, speech recognition section, information search section, speech conversion section, and packet control section. The speech control section performs speech communication with the radio portable terminal packet communication. The speech recognition section recognizes a speech signal received by the speech control section and sent from the radio portable terminal. The information search section searches for information on the basis of the speech information recognized by the speech recognition section. The speech conversion section converts the speech information of the information searched out by the information search section into a speech signal and outputs it to the speech control section.
