zh sound in English (and French)

The zh sound in English

When making this sound in English, the top and bottom teeth are close together, or even touching, and the tongue is up near the roof of the mouth. The tip of the tongue vibrates behind the top teeth barely touching the ridge behind the top teeth but not touching the back of the front teeth. If the tip of the tongue does contact the back of the front teeth, you'd be saying the "z" sound instead, as in zebra, or season.

Here are some examples of the "zh" sound in English:

beige (a color like tan, off-white, ecru)
pleasure
measure
leisure
closure
seizure
decision
amnesia
Asia

Note that in amnesia and Asia, "si" makes up the "zh" sound. The "i" isn't pronounced like an "i".

and many more...

Note that the sound is the same, though spelled sometimes with "g" or "s" or "z".
I don't think there are any words in English that start with that sound (at least none that are from the English language).

This sound is also common in French (including at the beginning of the word), in words such as:

je
juin
gilet
gymnastique
stage
