OperaVOX Multi

We have developed OperaVOX Multi™ specifically for Speech and Language Therapists, Laryngologists, Voice Coaches and Singing Teachers. 

Collecting timely, relevant and high-quality data on the voice is essential for measuring the ability of treatments such as surgery or speech therapy to improve vocal performance and quality of life. OperaVOX Multi™ is an easy-to-use portable voice analysis and feedback application for use by patients and professional voice users running on an Apple iPhone, iPad, or iPod Touch. OperaVOX Multi™ combines the signal processing power, easy connectivity, user-friendly interface, high-quality microphones and portability of these handheld devices with novel acoustic voice analysis algorithms to provide a powerful voice quality measurement tool that you can carry in your pocket.

Built into OperaVOX Multi™ are the validated Voice Handicap Index questionnaires and the ability to create individual patient profiles so that they can record their voice for acoustic and perceptual analysis both on board the device and externally in the speech laboratory. OperaVOX Multi™ can automatically and confidentially send these data via email to the surgeon, speech therapist, or researcher in real time.

OperaVOX Multi is now available to download.
