English speakers mispronounce 6 specific French sounds: the throat R, the U, é vs è, the GN, ILL (like "y"), and EN/AN. Master these and you sound 10× more natural.
French pronunciation isn't intuitive — written French has silent letters, multiple spellings for one sound, and 6 sounds English doesn't have. After 1 week of French class you can recognize; after 1 month you can pronounce; after 1 year you can hear the difference. This coach helps the first 1 week.
The non-obvious trick: French speakers know you're foreign anyway. They care more about your effort (Bonjour!) than perfect pronunciation. Get the sounds that change meaning (é vs è; "pain" vs "pin") right; the rest can come later.
Click each sound. Practice the mouth position in the mirror. Listen to native speakers (Forvo.com is great for individual words). Don't aim for perfection — aim for "not painful to listen to."
Months of practice for most adults. Gargling water helps visualize the throat position. Don't overthink — even an imperfect French R is better than an English R.
About 50% of French word endings are silent. "Paris" = "Pa-ree" (the s is silent). "Bon" = "boh-n" (n is silent unless followed by vowel). The liaison coach covers this.
Usually they're charmed by attempts. The "h" aspiré (H at the start of words) trips everyone up — but it's normal.
