Speech and language disorders in children

Speech disorders have a negative impact on communication. Childhood apraxia of speech (CAS) is a disorder affecting the motor programming of movements for speech. Children with CAS have difficulties achieving and maintaining the automatic control necessary for fluent speech. Breathing is the base in voice and speech production. Individuals with compromised respiration often have affected voice and speech. Projects we participate in deal with speech- and language development in relation to motor functions and disorders, perceptual assessment of speech disorders, co-morbidity in children with CAS and effects of early intervention for children with stuttering.
