Abstract

A method of displaying alternating transmitting and receiving phases of voice communication in a mobile phone with a display when it is operated in the speakerphone mode includes the steps of comparing the intensity of a received voice signal from a caller with that of a transmitted voice signal, outputting the received voice signal through the speaker of the mobile phone while displaying a visual indication representing the receiving phase on the display if the intensity of the received voice signal is stronger than that of the transmitted voice signal, and sending the transmitted voice signal to the caller while displaying a visual indication representing the transmitting phase on the display if the intensity of the received voice signal is weaker than that of the transmitted voice signal.

Claims

1. A method of displaying visual indication of alternating transmitting and receiving phases of voice communication on a display for a mobile phone when it is operated in a speakerphone mode, comprising the steps of:

comparing an intensity of a received voice signal from a caller with an intensity of a transmitted voice signal;

outputting said received voice signal through a speaker of said mobile phone while displaying a visual indication representing the receiving phase on the display if the intensity of said received voice signal is stronger than the intensity of said transmitted voice signal; and

sending said transmitted voice signal to said caller while displaying a visual indication representing the transmitting phase on the display if the intensity of said received voice signal is weaker than the intensity of said transmitted voice signal.

2. The method recited in claim 1, wherein the visual indications representing said receiving and transmitting phases are displayed as respective icons.

3. The method recited in claim 1, wherein the visual indications representing said receiving and transmitting phases are displayed as respective sets of characters.
