Method and apparatus for use in conjunction with voice messaging systems for determining playback volume of a message so that a good representation is provided for a voice-related portion of the message and the playback volume of a loud sound is reduced. In a preferred embodiment of the present invention, the log mean square power (MSP) of the message is determined while the message is being recorded and an MSP value for use in determining the playback volume is determined by analysis of the values received near the end of the message.
