One of the trickiest digraphs to teach new English Learners is the “Th” sound. This is because it isn’t a common sound produced in non-Latin based languages. In fact, with some exceptions like Arabic, Greek, Albanian and Burmese (for example), many languages do not have voiced or voiceless fricative “Th” sounds in their language at all. For Spanish speaking students, for example, learning words with the “Th” sound is very difficult. Most English Language Learners in my classes have expressed their frustrations in learning words with these voiced and voiceless “Th” sounds. What I always recommend to my students is their dedication to practicing words and sentences with these sounds in them to help them produce the sounds a little more fluidly. This is the primary reason I spend a great deal of time going over digraphs in the first place, especially when working with low beginner students and even all the way up to intermediate level students. An entire unit in the “I Want To Learn English” textbook is dedicated to practicing digraphs. I produced the following video for students to practice the voiced and voiceless “Th” sounds and give some examples to practice with. Please feel free to share this video with as many people as you like. Stay focused and practice as much as possible.
