In addition, when children are addicted to screens, they arent stimulated to be involved in conversations, causing speech delays. Broomfield and Dodds (2004a) found out after survey that 6.4% of children who are perfectly normal showed speech difficulty while they lacked these disorders will often show early signs and are at times identified as "at risk" when the speech delay is diagnosed. In the case of speech delay in a child with autism, there may not be a physiological cause such as an oral-motor issue or hearing loss. The child may prefer to communicate using non-spoken language or use a nonverbal communication method. Studies show that early interventions may help a child with cerebral palsy, autism spectrum disorder or Down syndrome acquire language skills necessary for social communication to a certain degree. Therapies and treatments
After the initial diagnosis of speech delay, a hearing test will be administered to ensure that hearing loss or deafness is not an underlying cause of the delay. If a child has successfully completed the hearing test, the therapy or therapies used will be determined. There are many therapies available for children that have been diagnosed with a speech delay, and for every child, the treatment and therapies needed vary with the degree, severity, and cause of the delay. While speech therapy is the most common form of intervention, many children may benefit from additional help from occupational and physical therapies as well.
Physical and occupational therapies can be used for a child that has a speech delay due to physical malformations and children that have also been diagnosed with a developmental delay such as autism or a language processing delay. Music therapy has effective results in the fundamentals of speech development, including phonological memory, sentence understanding, sentence memory, and morphological rule generation. Children that have been identified with hearing loss can be taught simple sign language to build and improve their vocabulary in addition to attending speech therapy. The parents of a delayed child are the first and most important tool in helping overcome the speech delay. The parent or caregiver of the child can provide the following activities at home, in addition to the techniques suggested by a speech therapist, to positively influence the growth of speech and vocabulary:

Reading to the child regularly
Use of questions and simple, clear language
Positive reinforcement in addition to patienceFor children that have a physical disorder that is causing difficulty forming and pronouncing words, parents and caregivers suggest using and introducing different food textures to exercise and build jaw muscles while promoting new movements of the jaw while chewing. Another less studied technique used to combat and treat speech delay is a form of therapy using music to promote and facilitate speech and language development. It is important to understand that music therapy is a newer therapy and has yet to be thoroughly studied and practiced on children with speech delays and impediments. See also
