「つ」の発音
tsu sound

Listen to the conversation below.


When pronouncing つ, pay attention to the location where your tongue touches in the mouth. See the following diagram.
The vocal tract cross-section diagram below is borrowed from https://soundsofspeech.uiowa.edu/.


The consonant of つ is a sound that pronounces "t" and "s" at the same time. Place your tongue blade (rather than tongue tip) on the gum of your upper teeth (arrowed part) and immediately release it to say "s." Listen to the audio and try to imitate it.

The consonant of ちゅ is made by touching your tongue more backward than when pronouncing つ. Listen to the audio and try to imitate it.

When pronouncing す, your tongue position is the same as when pronouncing つ, but your tongue never touches the gum. Listen to the audio and try to imitate it.
