The VSP-2 Speech Privacy System protects sensitive conversations across all workspaces: the office, the huddle room, the medium conference room, large conference room or boardroom, or even the multi-purpose room.

While it successfully masks information in the corporate environment as a white noise machine for the office, it’s also useful in education, healthcare, and even government settings.

Plus, when using other Yamaha UC Solutions like ADECIA, the VSP-2 sound doesn’t distract the team members joining remotely - the noise cancellation technology and human voice activity detection cancels it out.
