The interactive delivery of voice serve messages communicating financial, personal or other news telecasts can be accessed at a subscriber's convenience on an inbound telephone, network enabled or other call. A voice service bureau may generate voice messages for individual subscribers according to their natural language queries. For instance, a subscriber may inquire “What was the closing Dow today” and the system converts the request to digital form, discriminates search terms, interrogates a database and annunciates to the call “The closing Dow was 11,000 today”. Responses to those or other inquiries may be delivered in real time or substantially real time.
