[CAS -- R010] Motor Speech Delay 1

A new clinical term "speech motor delay (SMD)" is proposed to label children who have a delay in the development of speech motor control.

"Lengthened mid-vowels and diphthongs" is a frequent sign of SMD in children with idiopathic speech delay, complex neurodevelopmental disorders, and persistent idiopathic speech delay.

So, we can now classify children who do not meet the criteria of CAS, but with some signs of speech motor impairment.
