FThe following is a list of German consonant sounds. They will be listed together with their written correspondents; this way you will be better able to relate the sounds to words that you know. Moreover, the instructions of their articulation will be based on English as a native language. When we learn a new language, there will always be a certain amount of influence by our mother tongue. Perhaps you have listened to a German person speaking English viss a tsherman accent. 😉
One more thing: When you read the examples, it will be really helpful to you if you say them out loud and pay attention to what is happening in your mouth, i.e. how your lips and tongue move.
