    摘要: In a dialogue structure outputting speech items interrogating an access call while examining subsequently received human speech items for ascertaining an actual transaction instance further outputting speech in accordance with the ascertaining until either attaining a positive transaction result, or otherwise exiting the dialogue in case of failure. In particular, the dialogue is constructed from hierarchically arranged and callable subdialogues constituting respective mutually independent building blocks, which are arranged for generating a particular outcome if a positive result is attained by the subdialogue in question. The subdialogues offer interfaces for mutual coupling with a hierarchically superior subdialogue, so that the overall structure is formed as based on a selection of subdialogues and exclusively based on required partial results by each of the subdialogues in the structure.

    摘要: A transaction system has machine recognition of speech. It has dialogue control fed by the recognition, and speech generation fed by the dialogue control for outputting question and verifier statements from a repertoire set. A human-machine dialogue is executed until the dialogue control has recognized a viable transaction formulation with a plurality of user-provided slot fillers to specify the transaction. Dialogue control builds a directed and loopless status graph with nodes that each have their own slot filler and associated metric, and are interrelated through logic relations. The building can amend a node's metric and under control of conflict detection or lowering of a particular node's metric, discard the node in question and its filler, including of derived nodes and also of one-to-one derival nodes of the discarded node. A subset of problems is detected for a particular item outputted by the speech generation for ascertaining a particular slot filler, as combined with a subsequent unsatisfactory recognition. Then the speech generation outputs a further question statement for ascertaining the latter slot filler.

    摘要: The invention aims to make an automatic information system suitable for the input of requests which are spoken as naturally as possible and which are not subject to restrictions about which the user must be informed in advance. To this end, the system and the method are subdivided into several, essentially independently operating segments with unambiguous interfaces. A first segment serves for the recognition of words and outputs a word graph. A second segment forms a concept graph from the word graph in that essentially the word graph is searched only for word sequences wherefrom values for a database enquiry can be derived; such word sequences, or also single words, are replaced by concepts in the concept graph. In a further segment the concepts in the concept graph are bridged and gaps between the concepts are filled. A speech model is taken into account for this operation. A stochastic attributed grammar is used to determine the concepts from the word graph and to determine the meaning of the word sequences in the concepts. Because irrelevant filler words in the spoken request are ignored early on, the computational expenditure is comparatively small despite the freely pronounced requests.

    摘要: Successive sections of a computer program of a user interactive system are carried out. A user presents successive verbal items such as answers, to verbal items such as questions presented by the system. Each question corresponds to a respective program section. The user item is recognized and a next machine item is presented, if possible and appropriate. The recognizing is evaluated, and on the basis of the evaluating a progress score is kept. If the progress score attains a particular level, the system enables an operator to intervene in the dialogue in an unobtrusive manner. If a plurality of dialogs are supervised in parallel, the enabling is on the basis of a progress ranking among the dialogs. The intervention may be realized by emulating a user item in the form of speech or in the form of a mechanically entered user item.
