Abstract: A voice input system (100) includes a processing receiving unit (104) that receives identification information of a telephone that is to receive a callback, in order to input a voice, together with a voice recognition process request, a call processing unit (106) that originates a callback based on the identification information of the telephone received by the processing receiving unit (104), a voice data receiving unit (108) that receives voice data of a voice when the callback originated by the call processing unit (106) is received and the user's voice is input, and a voice recognition result storage unit (122) that stores result data which is data of a voice recognition result of the voice data received by the voice data receiving unit (108) in association with the identification information of the telephone.

Abstract: Disclosed is a dialogue speech recognition system that can expand the scope of applications by employing a universal dialogue structure as the condition for speech recognition of dialogue speech between persons. An acoustic likelihood computation means (701) provides a likelihood that a speech signal input from a given phoneme sequence will occur. A linguistic likelihood computation means (702) provides a likelihood that a given word sequence will occur. A maximum likelihood candidate search means (703) uses the likelihoods provided by the acoustic likelihood computation means and the linguistic likelihood computation means to provide a word sequence with the maximum likelihood of occurring from a speech signal. Further, the linguistic likelihood computation means (702) provides different linguistic likelihoods when the speaker who generated the acoustic signal input to the speech recognition means does and does not have the turn to speak.

Abstract: An information retrieval system comprises: a speech input unit for inputting speech; an information storage unit for storing information with which speech information, of a length with which text degree of similarity is computable, is associated as a retrieval tag; an information selection unit for comparing a feature of each spoken content item extracted from each item of said speech information, with a feature of spoken content extracted from said input speech, to select information with which speech information similar to input speech is associated. The system further comprises an output unit for outputting information selected by said information selection unit, as information associated with input speech.

Abstract: The present invention provides a topic transition analysis system that determines a position on a primary media stream leading to a certain statement made in a language communication carried out in a secondary channel associated with the primary media stream. The topic transition analysis system includes a statement trigger string determination unit receiving a primary media stream and one or a plurality of language communication streams (hereinafter, language streams) executed in parallel with the media stream and determining whether or not a certain statement on the one or plurality of language streams has been made newly in response to contents of the media stream.

Abstract: A first system for generating a language model is a system for generating a language model including: a topic history dependent language model storing unit; a topic history accumulation unit; and a language score calculation unit. In the system for generating the language model, a language score corresponding to history of topics is calculated by the language score calculation unit using history of topics in an utterance accumulated in the topic history accumulation unit and a language model stored in the topic history dependent language model storing unit. The topic history dependent language model storing unit may store a topic history dependent language model dependent on only most recent n topics. The topic history accumulation unit may accumulate only most recent n topics.

Abstract: Disclosed is a summarizing system including a speech input unit, an important portion indication unit, an important section estimation unit, a speech recognition unit, and txt summarization unit. The summarizing system captures a speech section, which is included in a speech received by the speech input unit and includes a portion specified by the important portion indication unit, as a section necessary for a summary. After estimating an appropriate section by the important section estimation unit, the summarizing system recognizes a speech considering the estimated section and performs text summarization.
