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 modular character of lingWAVES allows to offer different module combinations (suites) so that a wide range of professional users can use the system, starting from speech and language therapy, over Otolaryngology /ENT up to services for professional singers and speakers. You can also upgrade a lingWAVES module at any time.
