A portable communication device (1) has a microphone (5) and a processing device for receiving a handwritten message from a user and converting the received information into digital data. The processing device is operatively connected to the microphone (5), a keypad (6), and necessary means for normal operation of the communication device (1), so that sound caused by a user may be detected by the microphone (5) and forwarded, in electric form, to the processing device. The sound is recognised and either transformed into text on the display (4), used for moving a cursor on the display (4) or used for executing commands that control desired functions in the communication device (1).
