Portable communication device
First Claim
1. A portable communication device for conference calls, comprising:
- at least first and second speech encoder paths with first and second inputs for connection to first and second recording devices, respectively; and
at least one output connected to signal processor means for receiving and processing first and second electronic signals from said recording devices via said first and second speech encoder paths for transmission to a transmitter/receiver operatively connected to said signal processor means;
wherein said at least first and second speech encoder paths are integrated in said portable communication device and said portable communication device is adapted to receive said first and second electronic signals simultaneously even if the signals are different; and
wherein said portable communication device comprises a summator integrated in said portable communication device adapted to sum said first and second electronic signals into a sum signal for transmission to said transmitter/receiver.
