up, and the new glottis vibrates more widely and strongly. The voice takes on a fullness together with improved sound.
How is the esophageal voice made to resonate in the nasal cavity?
During speech, use the highest (uppermost) part of the new glottis to produce a voice as if sending it to the ceiling. Next, try to make it resonate in the deepest region of the nose. Of the 50 katakana characters, the nasal consonants are Ma-Mi-Mu-Me-Mo, Na-Ni-Nu-Ne-No, and Un. Practice humming as often as you can.
Making your words pass through the nose will produce clear, beautiful sounds.
