I’ve just gotten a copy of the Pronunciation Tutor /TH/ app by Keen Research for the iPhone. This app focuses on teaching the pronunciation of the /TH/ sound as in “Think,” which is often confused with the /t/ sound as in “tank,” the /d/ sound as in “dink,” the /s/ sound as in “sink,” and the /z/ sound as in “zinc.” If you are looking to improve your pronunciation of the “TH” sound, I suggest you get this app.
The reason this app is effective is because it first gives you the opportunity to learn to recognize the /TH/ sound and distinguish it from the /t/, /d/, /s/, and /z/ sounds. Listening is a key element in learning proper pronunciation and the Pronunciation Tutor /TH/ app provides many opportunities for listening practice. There is a listening test which has 50 examples of the /TH/ and /t/, /d/, /s/, /z/ sounds in single words and words in sentences. There are also three levels of practice exercises which test your understanding and ability to differentiate between Voiceless TH and T, Voiceless TH and s, Voiced Th and D, and Voiced Th and z. Can you recognize the differences between these sounds?
There are a few videos in the “How to Do It” section which show how to pronounce the Voiced /Th/ and Voiceless /Th/ sound along with a written explanation. The “Speaking /Th/” section gives you practice in pronouncing the /th/ sound along with the native speaker. The screen is divided in half, with the native speaker from the app on top. If you have an iPhone with a front-facing camera you can see your mouth on the bottom of the screen. This gives you the chance to shape your mouth just like the native speaker. This is the 21st Century version of using a mirror to practice your pronunciation. You do use a mirror when you practice English pronunciation, don’t you?
All in all, I really like the Pronunciation Tutor /TH/ app. It gives a thorough and complete lesson that you can study anywhere your iPhone is. This is the second pronunciation tutor app, and I highly recommend it for anyone looking to properly say things like, “Thank you for the birthday present.”
