THIS IS THE WAY I LEARNED. PLACE THE CALL IN YOUR MOUTH AND DON'T DO ANYTHING. GET USE TO IS SO YOU STOP GAGGING AND SALIVATIONG. WATCH TV, DRIVE, WORK AROUND THE HOUSE. AFTER A HOUR WHEN YOU STOP SALIVATING, TRY TO TALK NORMAL. AFTER TALKING FOR A BIT, A NOISE WILL MAJICALLY APPEAR. YOU WILL NOW BEGIN TO UNDER STAND WHAT EVERYONE IS SAYING. NOW YOU CAN PRACTISE MAKING ANY SOUND, AND SOON PROPER SOUNDS.
