Abstract

The invention discloses a sound input / output system and a volume output adjusting method thereof, which are used for automatically adjusting the volume of sound listened by a speaker according to the speaking sound of the speaker. The sound input / output system comprises a sound processor and a volume adjuster, wherein the sound processor is used for resolving the input sound received by a receiver, and the volume adjuster is used for adjusting the output sound of a loudspeaker according to a sound change value acquired by the sound processor. When the speaker changes the speaking volume along with the environment or the listened input sound, the sound processor can resolve the sound change value of the input sound, and then adjust the volume of the output sound according to the sound change value.
