The present invention provides an indication to the user of a voice
communication system that an echo at the user's location has been
detected by the system. In response to receiving this indication of echo,
users may take any of several actions to reduce the echo, such as
changing the position of the microphone or changing their own position
with respect to the microphone. The need for potentially expensive
echo-canceling hardware and software is reduced because the actions to
eliminate the echo are performed by the user. The echo detector in the
present invention may be implemented as part of a voice terminal, or as
part of a communication switch or server that is used in conjunction with
a voice terminal.
