About Eva


Let Eva show you how!


Eva (Exceptional Voice App) is a mobile voice training application. She was born out of the ever-growing need we all have to make efficient use of our time and energy.

It’s no surprise how difficult it is to change a voice. Eva will guide you step-by-loving-step over a series of lessons and courses. She will work tirelessly on your behalf to instruct beginners through advanced students on your journeys to a beautiful voice.

Many of you already understand the basic structure of training your voice because you’ve worked with other Exceptional Voice products. Now all the training elements are bundled together into a mobile app which you can use conveniently while at home or on the go — in your hotel room, office, airport, or wherever you may be in the world. Eva is a great travel companion; you won’t want to go anywhere without her. She helps transgender women feminize their voices safely and efficiently, and guides transgender men towards speaking with a rich masculine voice. But she won’t stop there!  Anyone, anywhere, who desires to change or enhance their voice or communication skills, can find what they need with Eva.

Giving Everyone a Voice!
