Both of my children have/had speech problems. They both started speech therapy before kindergarten. Their speech therapist suggested singing lessons. Anything that used their voice. It was amazing what they could do. We didn't have to pay for formal lessons. They joined the choir later in school and I got them in the choir in our church. They loved it. They could sing, and you couldn't tell that there was a speech impediment. Their pitch was a little off, but that is another story..lol. It gave them encouragement. Good luck!
