An iterative process is provided for interacting with a voice information service. Such a service may permit, for example, a user to search one or more databases and may provide one or more search results to the user. Such a service may be suitable, for example, for searching for a desired entity or object within the database(s) using speech as an input and navigational tool. Applications of such a service may include, for instance, speech-enabled searching services such as a directory assistance service or any other service or application involving a search of information. In one example implementation, an automatic speech recognition (ASR) system is provided that performs a speech recognition and database search in an iterative fashion. With each iteration, feedback may be provided to the user presenting potentially relevant results. In one specific ASR system, a user desiring to locate information relating to a particular entity or object provides an utterance to the ASR. Upon receiving the utterance, the ASR determines a recognition set of potentially relevant search results related to the utterance and presents to the user recognition set information in an interface of the ASR. The recognition set information includes, for instance, reference information stored internally at the ASR for a plurality of potentially relevant recognition results. The recognition set information may be used as input to the ASR providing a feedback mechanism. In one example implementation, the recognition set information may be used to determine a restricted grammar for performing a further recognition.

This paper proposes a new method and architecture for populating, updating and managing the NAB. It also proposes user's Contact Information Discovery (CID). In context of populating the NAB; since the NAB of each individual subscriber will be stored in the network in future, the paper proposes CI to flow from one NAB to another NAB within the core network, instead of CI flowing from Device to Network. Thus with the user authorization, his CI would shoot from one NAB to another NAB within the core network instead of from LAB to NAB through air interface. It would reduce huge amount of data traffic on the air that otherwise would be generated in updating and populating the NAB by all the NAB users. In context of CID, the paper proposes a query-response mechanism and introduces a NAB Manager. The new architecture will provide several benefits for example it will eliminate the need of “Number Portability,”“United States National Do Not Call Registry” and “411 Directory Assistance.”
