COMPARISON BETWEEN ENGLISH AND JAPANESE VOWELS

Front, central, and back represent the backness of the vowel or which part of your tongue is moving. Front means the front part of your tongue. Central means the center part of your tongue. Back means back part of your tongue.

 High, mid, and low represent the height of the vowel or the distance between your tongue and the roof of your mouth. High means your tongue is raised high or up that it is near your tongue. Mid means your tongue is in the middle position, it is not near nor far from the roof of your mouth. Low means that your tongue is far from the roof of your mouth. Usually, teachers say that you need to drop your jaw to pronounce these sounds, BUT remember, NEVER DROP YOUR JAW TOO MUCH. It is tiring and difficult, and it will not sound and look natural.

Look at the table above. The red ones are sounds in English that DO NOT have any similar sounds in the Japanese sound system. *The blue ones are sounds that HAVE small similarities to the American sound.

The sounds in red font colors are the sounds that are COMMONLY MISPRONOUNCED by students because it does not have a direct counterpart in the Japanese sound system.
