Un peu de prononciation
Pratique de la prononciation – les voyelles nasales
In French, a syllable or word ending in one or more vowels followed by -n or -m produces a sound called a nasal. The -n or -m is not pronounced, but its presence changes the sound of the vowel in front of it. The back of the tongue is raised towards the roof of the mouth, and the vowel sounds more “nasal,” as if your nose is stuffed up. There are three commonly used nasal sounds in French today (with the fourth sound less commonly distinguishable), each of these sounds is captured by several different spellings.
This video will help you hear, identify and practice these common French sounds.
