Yes. If your aim is to move Kumaresan’s Oropharyngeal Facilitation/UMAR approach from an individual clinical technique into a procedure that the wider medical community can understand, reproduce, measure, and critically evaluate, the strongest route is to build a coordinated ENT + speech-language pathology + biomedical engineering research program.
Your published UMAR work already gives you an important starting point: the 2021 paper described uvula manipulation, resonance and laryngopharyngeal manipulation for puberphonia, and reported 600 cases at that time. � Your current figure of 1700+ treated patients would be an important new clinical dataset if it can be systematically documented.

One terminology point is particularly important for scientific acceptance: I would avoid stating that the pharyngeal walls are replacing the vocal folds as the primary vibrating source. In conventional voice physiology, vocal-fold vibration remains central to voiced sound production; your hypothesis can instead be framed as redirection/reorganization of phonatory-resonatory behavior toward an oropharyngeal/pharyngeal configuration, with changes in laryngeal tension, vocal-fold behavior, resonance and perceived pitch. That wording will make the hypothesis much easier for ENT and voice researchers to test.

The most important project: prove the mechanism
I would make Project 1 the flagship:
"Objective Characterization of Oropharyngeal Facilitation and Phonatory Redirection in Puberphonia."
Record patients at four stages:
Baseline → during facilitation → immediately after treatment → long-term follow-up.
At each stage collect:
fundamental frequency (F0)
pitch range
CPP
HNR
jitter/shimmer
formant frequencies
spectral characteristics
intensity
EGG/contact quotient
aerodynamic measures where available
flexible laryngoscopy/stroboscopy
perceptual voice rating
patient-reported outcome
standardized speech samples
This would convert your clinical observation — "the voice changes when phonation is facilitated toward the oropharyngeal/pharyngeal configuration" — into a measurable scientific hypothesis.
A particularly powerful engineering experiment
Ask the biomedical engineering team to build a synchronized multimodal recording system.
During one treatment session:
Camera → larynx/pharynx
↓
Microphone → acoustic voice
↓
EGG → vocal-fold contact
↓
Airflow/pressure → phonatory aerodynamics
↓
AI → synchronized analysis
Then create a time-locked graph:
High-pitched voice → facilitation → transition → lower-pitched voice
If the transition consistently corresponds to measurable changes in acoustic, EGG, endoscopic and/or aerodynamic parameters, you will have something much stronger than a descriptive clinical claim.
Project specifically for "awareness of the medical community"
I would actually make this a separate research study:
"Awareness and Understanding of Puberphonia and Oropharyngeal Facilitation Among ENT Surgeons, Residents, Speech-Language Pathologists and Medical Students."
First ask participants questions such as:
What is puberphonia?
Is the larynx structurally normal in typical puberphonia?
What treatments do you currently recommend?
Are you familiar with UMAR?
Are you familiar with oropharyngeal/pharyngeal resonance facilitation?
Do you believe pitch lowering necessarily requires forceful laryngeal manipulation?
Would objective acoustic/endoscopic evidence change your treatment approach?
Then give a 10–15 minute demonstration using your 1700+ patient database, followed by the same questionnaire.
That gives you a measurable answer to:
"Can objective demonstration of the Kumaresan technique change medical understanding of puberphonia?"
The AI project could become your signature project
Your existing AI/VR direction fits this exceptionally well.
Build a "Puberphonia Voice Transformation Index".
For every patient, AI calculates:
PVI = f(F0 + CPP + HNR + formants + spectral characteristics + perceptual rating + patient outcome)
The system could display:
BEFORE
High-pitched voice
↓
FACILITATION
↓
AFTER
Adult voice pattern
Eventually, the clinician could see a real-time indicator:
Oropharyngeal facilitation achieved: 87%
That number would initially be a research metric, not a clinical diagnostic claim, until properly validated.
Do not start with 10 projects simultaneously
I would recommend a three-stage program.
Stage 1 — Document what you already have
Your 1700+ cases are potentially your greatest research asset.
Create a retrospective database containing:
age
duration of puberphonia
pretreatment F0
post-treatment F0
treatment duration
immediate response
follow-up
recurrence
associated voice problems
video/endoscopic findings where available
Then prospectively standardize every new patient.
Stage 2 — Prove the mechanism
Run the synchronized acoustic + endoscopic + EGG/aerodynamic experiment.
This is where the biomedical engineering departments become essential.
Stage 3 — Compare treatments
Once the mechanism and measurement system are established, conduct a prospective controlled study comparing:
Kumaresan Oropharyngeal Facilitation/UMAR
versus
standard behavioral voice therapy
with blinded acoustic/perceptual assessment.
Current evidence supports behavioral voice therapy for functional voice disorders, but the literature also shows considerable variation among approaches and limitations in study quality. A 2026 network meta-analysis of 30 RCTs found significant improvement with several voice-therapy approaches, highlighting the need for well-designed comparative studies. �

One very important scientific opportunity
Your central hypothesis could be reformulated as:
"Puberphonia may involve maladaptive phonatory-resonatory behavior rather than simply an inability of the larynx to produce an adult fundamental frequency. Oropharyngeal facilitation may provide a sensory-motor pathway that reorganizes phonatory behavior, reduces maladaptive laryngeal tension, and facilitates acquisition of an adult voice."
That is a hypothesis that ENT, speech science, neuroscience and biomedical engineering can all investigate.
It is also more scientifically defensible than saying simply that "phonation is transferred from the larynx to the pharynx."
Your existing publication gives you a legitimate starting point, rather than starting from zero. �
PubMed
If I were structuring this as a major research program, I would call it:
Kumaresan Puberphonia Research Initiative
"From Clinical Observation to Objective Pharyngeal Phonation Science"
with three flagship arms:
Pharyngeal Phonation Physiology
AI-Based Objective Voice Measurement
Clinical Validation of Oropharyngeal Facilitation
This could be an unusually strong collaboration between ENT + SLP + biomedical engineering + AI + acoustics + endoscopy, and it directly addresses the question you are asking: not merely "Does the technique work?", but **"What exactly happens, how can we measure it, why does it work, and can another clinician reproduce it?"**
