The initial Y sound
How the initial Y sound looks and how it is made:
The tongue begins in a high forward position in the mouth with the sides of the toungue in contact with the upper teeth. Tongue moves in a gliding motion from this position to a more open position with the tongue relaxed in the lower part of the mouth. The lips are slightly open, and the jaw (lower mandible) is elevated. The vocal cords produce vibrations for this sound. The feeling for this sound comes from the gliding action of the tongue from the high forward position to a more relaxed position in the lower part of the mouth, and that it produces vibration in the cords.
