Voice Care: Does it lead to Avatar Therapy?

Dr. M. Kumaresan (E-mail:

Dr. Navin Kumaresan

Professionals can use their voice to gain kinetic energy- “Bernoulli’s Principle”. Evidence shows virtual reality remodeling can create “Avatar Therapy”.

Voice care can be beneficial to professional voice users, including motivational speakers, who are at risk for either overusing or abusing their voice. They will require voice analysis and voice care. They need voice analysis and care.

Subglottic pressure is required for the production of voice. Aerodynamic theory is based on Bernoulli’s principle of fluid energy. The theory states that when a stream of air flows through the glottis while the arytenoid cartilages are held together by the action of the inter-arytenoid muscle, a “push- pull” effect is created on the vocal fold tissues maintaining a self-sustained oscillation.

The dynamic balance in the vocal folds is necessarily involved in the subglottic pressure. Singers who try to control sound by using their neck muscles can impair their vocal function and quality

The ability of a singer to either sustain or vary a steady subglottic pressure depends upon accurate voluntary control of respiration by the abdominal muscle.

Modeling of Voice Transmission in the Human Respiratory Tract

Aim: To create “Avatar” or “Virtual Reality” therapy to help voice care. This model will be created using computer software.

Model Function:

Functional movement of the desired organ can be stored by stimulating it, which in turn activates the brain cortex. The stored message in the brain cortex can be functionally reactivated even after a peripheral organ disease.


Four Phases

Phase 1 Mind Reality Therapy: 3 D Imaging and screening of the video to create a feeling of reality in mind.

Phase 2 Physical Reality Therapy: To create a feeling of physical involvement similar to a skill game or playing a virtual sport. .

Phase 3 Virtual Reality Therapy: Creates an ability to re-enter virtual reality and make changes

Phase 4 Avatar Therapy: Final phase involves modeling or imitation of both physical and mental aspects of humans. Intervention can be done on the model to obtain the best results on the “Avatar” body. This process can be studied and duplicated on actual people. This would prevent the need for human or animal testing during clinical trials.

Currently, working on Phase 1

3 D – Mind Reality Therapy

3D – Virtual Reality Treatment Theatre

1. Audio Visual Support

2. Mobile seat with accessories

3. 3 -D Filming of treatable ENT conditions by Avatar therapy. Some of the conditions are as follows:

a. Acrophobia (Fear of heights)

b. Aerophobia (Fear of flying)

c. Nyctophobia (Fear of dark places)

d. Siderodromophobia (Fear of trains)

e. Phonophobia (Fear of sound)

f. Treating teachers, singers, and other professional voice users

g. Eating disorders and obesity

h. Sleep disorders and snoring

i. Vertigo and balance

j. All endoscopies

k. Cyber sickness

4. Surgeons and computer software engineers.

5. Training Emergency services

Avatar Modeling of Voice Transmission in the Human Respiratory Tract


To better understand the speech generation process and execution by modeling of the human respiratory tract. Three Dimensional imaging of the kinetic model of respiratory tract in normal individuals and on people with disease condition


1. To build an adequate model of the respiratory tract in normal speech production and respiration

2. Next, the model should be used for simulations of pathological larynx (Respiratory Tract)


Kinematic analysis of motion will be performed by using Mc Adams and Mathematica software. The geometry of mobile parts of the larynx and the parts voice production is taken into consideration in order to investigate its influence on voice transmission properties. To find out adequate movement of the vocal cord and subglottic pressure in our model, an experiment on human larynx is performed in comparison with computer model. The dynamic analysis will be performed with to help of matlab.


First parameters of the proposed model are estimated by comparison of experimental results with model one. Next, the key parameters of the model are chosen for the reason of its practical implementation in surgical procedures.


The dynamic model of respiratory tract which produce voice can be useful to predict damage in human voice apparatus and to choose the best method of voice problem treatment.

The modeling or Avatar or virtual Image will help for continued practice of voice and prevent recurrent problems, which are the key exercises needed to prevent recurrences.

We can enhance audiovisual integration beyond normal capabilities. We used f- MRI and H2 15 O Pet to investigate and access the meaning from auditory, visual and audiovisual speech areas. By using audiovisual stimuli for which meaning could be accessed either from the auditory or visual modality alone or, from both models simultaneously.

Speech processing from sensory modalities involves the bilateral superior temporal gyrus and sulcus.


Surgeons can be trained with 3 D videogames in the virtual reality theatres. They require training to develop the skills to handle these high tech devices.


The dynamic model of any organ can be used to predict damages, and to choose the best method of treatment. This is a lifelong process and every individual can have their own model. The treatment can also be done online via the internet.
