UMAR

To achieve a "pharyngeal voice in puberphonia" or a voice that resonates more in the throat, you can try placing your hand on one side of your mouth and focusing on a relaxed, open throat while speaking, aiming for a sound that feels like it's coming from the back of your throat. 

How to achieve it:

 Imagine the back of your throat open and sending the sound outwards. Focus on uvula as snoring, vowel shapes to find what resonates best in the pharyngeal space. 

Diaphragmatic Breathing: Practice diaphragmatic breathing by UMAR to support the voice and prevent tension in larynx. One can sound as much as possible, but never injury to the larynx , because vocal cords never get vibration.
