Abstract

The present invention relates to a mobile set integrating a memory efficient data storage system for the real time recording of voice conversations, data transmission and the like. The data recorder has the capacity to selectively choose the most relevant time frames of a conversation for recording, while discarding time frames that only occupy additional space in memory without holding any conversational data. The invention executes a series of logic steps on each signal including a voice activity detector step, frame comparison step, and sequential recording step. A mobile set having a modified architecture for performing the methods of the present invention is also disclosed.

Claims

1. A mobile set having a voice recording means for storing voice conversations received through the mobile set and capable of playback on the mobile set, the mobile set comprising:

(a) a uplink/downlink switch for selecting speech frames from either a uplink or downlink signal;

(b) at least one switching logic controller for switching between the uplink and downlink signals;

(c) a method of file header generation for generating headers for recorded speech files;

(d) a recorder controlling means for configuring and controlling of a recorder operation in one of several modes available to a subscriber; and

(e) a memory element.
