Website Review: http://www.uiowa.edu/~acadtech/phonetics
In short: Extremely helpful for pronunciation—this website lets you see how to pronounce English sounds. You really need to visit the site to understand how great it is. You can click one button to see how each sound is pronounced inside the mouth. Another button gives you a step-by-step description. You can also see the sound from the outside and hear it pronounced at the beginning, middle, and end of a word.
Linguistics students who are having trouble understanding their textbooks will also enjoy this site. They’ll finally understand what all those strange words are describing.
For students: If you have trouble with the vocabulary, there is a glossary in the top right that defines the words.
For teachers: Try brining your students into a lab (or assigning the site for homework). The students should choose a sound that is difficult for them and write a sentence that contains the sound five times. For example, a student that chose “L” might write: Lovely ladies look lovely. They every time they make a mistake with that sound in class, you can ask them to say their sentence.
