Do you know how to pronounce the f sound. The f sound is a a labiodental. You should put your lower lip and upper teeth together. Then make air pass between them, saying f.
The p sound is a labiodental. You should put your lips together and make the air pass through your lips, saying p. In Korea, people have difficulty in pronouncing the f sound, for we do not have such a sound. So you have to practice how to say the f sound. Look at the picture cards. Let's practice together. Repeat after me.
I have made directions for students about how to make the f and p sounds. Would you chek them, plese. If you have better expressions, add them, please.
It all sounds fine.
