According to my records, I did not put 2 words together until ages 3-4. I had a severe language disorder and a moderate articulation disorder when I entered Kindergarten. By age 6 3/4, however, my speech was excellent. I was monotone until about 4th grade, however.
Today, I can speak normally, with normal intonation. I may slip a bit here and there, but I can generally pass for neurotypical, according to others.
