My DS2 has motor Dyspraxia - the more usual kind. And yes, he does appear clumsy - it affects gross and fine motor skills, co-ordination etc.
My DS3 has Verbal Dyspraxia - the same basic "fault", in that the signals from the brain get jumbled, but it just affects the muscles used for speech. In some cases this can also affect eating. He is very well co-ordinated, no clumsiness at all.
I know there are other MNers with DCs with Verbal Dyspraxia who have really struggled, but my DS3 is a real success story. It's been a long hard slog of intensive speech therapy but now, at 7, he's almost always understandable. He had to be taught each consonant sound individually - where other children learn speech by imitation, verbal dyspraxics have to be taught just about everything - where to put the tongue to make the sound "T", how that's different than where the tongue is for "L", for example.
When he started school he had a Statement of SEN, which means he's had 20 hours a week of 1:1 support, and so did speech therapy exercises daily. When he's tired or stressed or in a hurry, the speech slips and is hard to understand. He will always sound a bit unusual and robotic, but he's popular and happy, and his friends can understand him now.
You do have a tough few years ahead, and will have to make damn sure you get the speech therapy that's best for your DD, but there is certainly hope.
