Abstract：In order to support cooperative work in enterprise environment, voice tool should provide flexible floor control mode. Because mixed audio is not clear in existing voice tools, they have freezing floor control mode only where members talk by turns which limits the free discussing among group. In the paper, a new mixed audio algorithm, which improves voice quality, adopted by voice tool ENVoice (Enterprise Network Voice tool) is provided. It is very important to support cooperative work.
