A power indicator is proposed as a device to improve user-interface in speech input. It enables a user to check the power of his/her utterance correctly and easily in realtime. A number of speech recognizers and speech filing/messaging systems have been announced. But they have no efficient interface for a user to check the loudness of his/her utterance. For example: One system displays on the console such a message as "Speak louder!" in case of too low speech and "Speak lower!" in case of too loud speech. However, a user has no means to know to what degree he/she should speak louder/lower. Another system displays a bar whose length changes according to the power of the moment or the peak power in a short period of time. This provides the better user-interface than the above.
