MK Prosopsis


A leading tested product for voice and speech analysis, biofeedback and documentation


lingWAVES has become one of the most used system for professional voice and speech analysis, biofeedback and documentation in the last years. A combination of standard and new technology analysis and processing together with an easy handling are the key features of this unique system.

The system consists of different modules managed by the lingWAVES basis user interface. A client manager allows a patient/client based analysis and documentation with the benefit of comparing and tracking results over time.

You can also upgrade a lingWAVES module at any time.
