You do not pronounce the "g" in French and the "on" sound is closer to "lumprey" in English.

Check it out by typing it on this IPA:

Lon-pray

Lon: same sound as in long without the g which is a mute letter in French.

Definitely NOT 'Lon' as in London which would be sounded ' lone' as in pylon.

It is the French sound of 'on' where the n is not accentuated as it is in the English language.

L-oh-ng-pray

The ending sounds like "Ay"

The "o" kind of has a "stuffed up nose" kind of sound

Longpray

I could be wrong. "é" is usually pronounced "ay" in French, so I went for my best guess

it sound like

longupea

AT THE END IS A SOUND THAT SOUND LIKE THE LETTER A AS IN "A" AND NOT AN E SOUND LIKE IN "PEA".
