Abstract

Current voice message systems typically operate by recording a message that people leave for a user. However, these current systems do not process the message in a manner where significant information, such as phone numbers, meeting times, and locations, is identified, extracted, and output. The present invention solves the current system'"'"'s limitations and extracts pertinent data from a voice message. In addition, the present invention is versatile because it is applicable to a recorded or live voice message, and any type of phone can actuate the extraction mechanism. The invention builds on voice recognition technology by identifying data, for instance, common phrases and strings of numbers from a voice message. Next, the invention provides an interface for actuating extraction technology. In one embodiment, the extraction technology removes information based on user commands according to a series of keystrokes. In another embodiment, the invention extracts information by a user'"'"'s voice commands. Consequently, when a telephone user encounters a situation where he/she is unable to write down a phone number or other information, the user will be able to quickly access the invention to find the number or other piece of relevant information and save it for retrieval later. This invention saves the user time and frustration from constantly replaying the same message. It also saves money by reducing fees from repetitive and redundant telephone calls. With simple keystrokes or voice commands, a user can immediately access extracted information and make his/her desired telephone call.
