In my opinion, the hardest part in teaching EFL is the pronunciation. Some of my students, a lot of them, can’t pronounce English consonants well. Let alone, Sundanese students have a difficulty in distinguishing the sound /p/ and /f/. They tend to pronounce both sounds the same. For instance, the phrase four pipes is sometimes pronounced either /fɒ: faifs/ or /pɒ: paips/.
I’ve tried to get them practice the /f/ and /p/ so many times, but I’m afraid my effort is useless. Hence, I told them to practice the English tongue twisters at home frequently hoping that one day, they’ll have better pronunciation. Here is some tongue twister practice I got from both other sources and my own thought.
Practice of /f/ and /p/: That fat Piper picked up five pipes and four flat plates
Practice of /ð/, /θ/, and /t/: They think that their teeth get thinner at times they want to taste think meat
Practice of /s/ and /ʃ/: She shall see the seashore so she can sing
Practice of /ʤ/ and /ʧ/: Joy to see your chin, jaw and cheek
Practice of /ʃ/ and /ʒ/: She has vision to share pleasure with Natasha
So, that’s some tongue twisters for all EFL learners to practice distinguishing the consonant sounds. I hope it’s useful.
