Voice Builder™ is a breakthrough iOS application for bringing power, resonance, range, flexibility, and endurance to the singing or speaking voice. It is the only application of its kind to be based on The Catona Voice Building System™, the revolutionary vocal exercise program for developing the muscles of the human voice.

The Catona Voice Building System is the brainchild of renowned voice builder Gary Catona, who has trained many of today’s most successful singers and entertainers, including:

- Whitney Houston
- Andrea Bocelli
- Babyface
- Sade
- Seal
- Usher
- Shakira
- Lenny Kravitz
- Tony Bennett
- Lionel Ritchie
- And many others


- Neutral Tone Technology™: Instead of vocalizing to a pre-recorded human voice (and its imperfections), you instead vocalize to a tone that is always in perfect pitch.

- Voice-building exercises play automatically with a simple touch of a button. 

- Volume & pitch guides provide an effective visual aid in performing voice-building exercises in the correct pitch and volume.

- Over 20 voice-building sessions for both male and female singers and speakers. A setup wizard makes choosing the right voice-building session quick & easy.

- Gary Catona guides you every step of the way with audio commands and numerous video demonstrations. 

- A short video tutorial gets you up to speed quickly on both The Catona Voice Building System and the Voice Builder application.

Long considered a well-guarded secret in the entertainment industry, Voice Builder now makes the Catona Voice Building System available to the world by means of an elegant, innovative, and intuitive application which is a pleasure to use, whether it be at home or on-the-go.

Mr. Hawdini ,


Better than expected and with a few changes will be legendary. First a way to record your voice and make notes on progress. Second a way to set your own warm up and practice ranges. Third complete video examples of professional male and female, pop, rock and opera, voices singing from the freakishly low to the high notes only dogs can hear : ) in full voice. For example a male rock singer demonstrating the low voice of E2 up to G#4 then showing the upper range all the way to E6. And the ability to have a video demonstration of any single note, male or female, child, teenager or adult pop, rock or opera at the press of a button. Also examples of younger girls and boys doing the exercises. That being said as it is the app is a treasure for female and male singers and speakers of any age and type of music.


Wow. The results after 2days?!?

My sister actually trained with the creator and always had great things to say about Gary. I didn't have the money to train with him back them so when She texted me about this app 2days ago , I was on it !!! And the results after deliberate practice in 48 hours are amazing. I speak better , I support better, breathe better, I sing better. It's like my body's getting conditioned to do things the right way. So happy about the progress and strongly recommend this app to all singers and speakers. Enjoy! ALXSMIRANDA

Great once you get the concept

This app is great once you understand the methodology behind Cantoas approach. It’s definitely a huge departure from conventional vocal training ideology but his approach to building the voice is based on making the voice stronger and this app is a great tool toward that goal. True, his approach offers little variety in ways of scales and exercises but it’s nonetheless a valuable tool for any singer looking to expand the range and muscularity of the voice.
