I was a french major in college and in my upper level courses I had to lead many class discussions in French. I found what works for me is to practice on my own for a bit, then practice in front of a close friend. Note cards helped me out a lot too. Sometimes, reading something aloud helps me with my speech so if I know there’s a word that I stutter on, I’ll write that one word down and read it aloud from the note card. Good luck! Keep us updated
