1. A method for manipulating and managing information in a digitized data stream, comprising the steps of:
- receiving the digitized data stream, wherein the digitized data stream comprises a digitized audio message;
receiving guidance representative of the structure of the digitized data stream;
analyzing the digitized data stream, wherein the analyzing step comprises performing a speech recognition operation on the digitized audio message, identifying a plurality of words within the digitized audio message, and storing the position within the digitized audio message of each word;
determining whether a portion of the audio message represents a telephone number or a name;
using the guidance to identify at least one significant data item within the digitized data stream and selecting a date contained within the digitized data stream as the data item; and
storing a pointer to the significant data item.

Abstract
A system and method for extracting key information from digitized audio messages, including telephone voice messages. Information, such as a telephone number and the name of the caller, is derived and extracted from a voice message and used to establish links to the information within the message. The telephone number and name of the caller can then be replayed without the need to replay the entire voice message. The telephone number and name of the caller can also be used as indices into an information database.
