DoctorVox

DoctorVox DoctorVox Voice Therapy is a direct technique for general use. Aut viam inveniam aut faciam. Everything started with a simple glass tube more than a century ago.

The meaning of these words, attributed to Hannibal, is that you will either find a way or make one. A smart Finnish Voice pathologist, Marketta Sihvo invented a silicone tube The LaxVox. In time, after using kilometers of silicone tubes, new devices were devised by a laryngologist & phoniatrician, Ilter Denizoglu. The DoctorVox Voice Therapy Technique (DVT) is not about phonating into a tube with one end dipped into the water. It is a multilevel- multidimensional treatment and training system using scientifically proven physical tools. DVT is an efficient approach for voice professionals. Singers can use it to warm up and cool down and to find the ‘position’ of the singing voice. Relaxing the unnecessary muscle groups increases the consciousness of the vocal mechanism. In the voice clinic, DoctorVox Therapy System is a holistic therapy for various functional and organic voice disorders (muscle tension dysphonias, vocal fold nodules and polyps, habitual and psychogenic dysphonias-aphonias, vocal fold paralysis, presbiphonias, pre, and postoperative phono surgery, etc.) The manufacturing and distribution of the DVT devices were possible after the DoctorVox team was born from the union of an engineer and a physician. The engineer, Atilla Ozbilen, is an IT manager and an entrepreneur as the one who started the possibility of production and distribution of the devices. DoctorVox devices are based on functionality, high-quality materials, and hygiene. The research and development process continues with new advancements. As often stated, necessity is the mother of invention. DoctorVox is a company dedicated to the research and development of the human voice. In the vision, DoctorVox has a true sense of purpose in “creating a better voice.”

Our Story

In 2003, in a PEVOC Conference in Graz, a Turkish laryngologist and phoniatrician, Ilter Denizoglu has attended Marketta Sihvo’s workshop. He has studied the LAX VOX –tube exercise for two years in his clinic and laboratory. After two years, Sihvo and Denizoglu met again and decided to work together. They have presented the method as LVVT (LaxVox Voice Therapy) in various international conferences until 2014.

In time, Sihvo’s LAXVOX-tube exercise was modified and expanded by Denizoglu into DoctorVox Voice Therapy Method (DVT). DVT is a multi-level, multi-dimensional treatment approach with a well-defined exercise program based on motor learning principles. DVT provides a muscle-specific exercise program for clinical and pedagogical practice combining medical, pedagogical and physical principles.

New devices were additionally devised by Denizoglu (doctorVOX®, pocketVOX®, maskVOX®) for DVT applications. The backpressure was adjusted by an in-built valve. In advance, a unique oral mask was devised by Denizoglu to provide free articulation during laxvoxing. The maskVOX (voice-mask, stimm-maske), was appreciated especially by singers: the magic effect (a term by users) of voice mask astonished many.

Habilitation of professional voice and rehabilitation of voice disorders: In the way of finding the best solutions for the human voice, the DoctorVox excursion continues with new devices and studies.
