He is known as a person with learning.

In Sanskrit phonology, retroflex sounds play an important role.

Retroflex sounds are difficult to pronounce.

A coronal is a sound that is pronounced using the tip or the upper part of the tongue.

A dorsal sound is a sound that is pronounced by the back of the tongue approaching or touching the palate or pharynx.

This audio is very clear.

The sound was so quiet that I could hardly hear it.
