Speech Disorders | Symptoms & Causes
What are the symptoms of speech disorders in children?
The symptoms of a speech disorder depend on the type of disorder a child has but may include:
- Missing or incorrect consonant or vowel sounds
- Speech that’s harder to understand compared to that of other children of similar age
- Repeated sounds
- Hoarseness, unusually high or low pitch, or nasal-sounding speech
Identifying early signs of speech disorders
As children are learning how to speak, it’s not unusual for them to have some of the features described above. Often this is temporary and not a cause for concern. If your child isn’t reaching speech milestones, is falling behind other children their age, or you have concerns about your child’s speech or ability to make certain sounds, it’s a good idea to have them evaluated by a speech-language pathologist.
What causes speech disorders in children?
In many cases, children have speech disorders for no known reason. Possible causes include:
- Structural issues, for instance, cleft palate, that interfere with a child’s ability to pronounce words.
- Vocal nodules or polyps that affect the sound quality of a child’s voice.
- Hearing loss (temporary or permanent)
Speech disorders can also be caused by other conditions or injuries:
- Autism spectrum disorder
- Cerebral palsy
- Chronic ear infections
- Down syndrome
- Genetic (present at birth) conditions
- Hearing loss
- Pediatric stroke
- Traumatic brain injury
Speech Disorders | Diagnosis & Treatments
How are speech disorders diagnosed in children?
Given the number of speech disorders and their many possible causes, diagnosis sometimes requires a team of speech-language pathologists and otolaryngologists. The comprehensive speech evaluation will include parents’ and clinicians' observations, standardized testing, and diagnostic therapy.
How are childhood speech disorders treated?
If your child is diagnosed with a speech disorder, their treatment may begin by addressing the condition that’s interfering with their ability to clearly form words.
Most children with speech disorders receive weekly speech therapy with a home programming component to help them practice their skills. The focus of therapy will be tailored to your child’s specific condition:
- Therapy for a phonological disorder or articulation disorder aims to help children identify sounds they can’t make and practice new ways of making those sounds.
- Therapy for dysarthria aims to increase breath support, encourage precise articulation, and may include changes in the child’s environment (home and school) to improve intelligibility.
- Therapy for childhood apraxia of speech helps children establish consistent and correct movement between sounds.
- Therapy for stuttering incorporates acceptance-based strategies and techniques to promote fluency and self-advocacy skills.
- Therapy for voice disorders improves the quality and manner of voice production and coordination of respiration with phonation.
- Therapy for resonance-related disorders aims to achieve adequate oral airflow and articulatory placement for speech sounds produced incorrectly due to compensation and mislearning.
