1. Does delayed speech affect intelligence?
Delayed speech is very common—on average, one in ten children experiences delayed speech. When a family has a child with delayed speech, parents often worry and wonder if their child is less intelligent. However, parents should not be overly concerned because language development varies from child to child.
The timing of when a child begins to speak does not affect their intelligence. Parents should distinguish between cases where delayed speech is part of a broader developmental delay, including delayed walking or other milestones, and cases where a child is only late in speaking but otherwise develops normally, such as crawling and walking. In the latter case, delayed speech does not indicate developmental delays or a lack of intelligence.
Delayed speech is not a serious problem, so parents should avoid excessive worry. However, if a child exhibits any of the following signs, they should be taken to a healthcare provider for evaluation and treatment:
- The child does not react or respond specifically when their name is called. At 18 months, the child communicates only through gestures and avoids speaking.
- The child frequently struggles to repeat words spoken by parents. At age 2, the child cannot form sentences or phrases and only imitates actions or words from parents.
- The child cannot follow simple instructions from parents or relatives.
- The child has an abnormal voice.
2. Causes of delayed speech
2.1. Language developmental delay
Delayed speech, or language developmental delay, can result from various factors. It may occur as a symptom of slower language processing in the brain despite normal psychological and intellectual development. Alternatively, it may be associated with conditions like autism or cerebral palsy. Intellectual disabilities can also contribute to delayed speech. Children with hearing impairments are at risk of delayed speech or even the absence of language development.
From a physical perspective, delayed speech can result from anatomical abnormalities, such as issues with the palate, tongue, or cleft palate. A short lingual frenulum can restrict tongue movement, making speech difficult. Hearing problems also significantly impact speech development, which is why doctors often recommend hearing tests for newborns. Difficulty hearing impairs a child’s ability to mimic, learn, and use language.
Psychologically, excessive exposure to smartphones and television is a common cause of delayed speech. Modern devices, while engaging, can hinder language development by reducing opportunities for interaction. Watching screens excessively prevents a child’s brain from engaging in active thought, leading to a habit of being less verbal and avoiding social interaction.
2.2. Einstein Syndrome
Einstein Syndrome is a condition in which children exhibit delayed speech but possess exceptional intelligence. Signs of this condition include excellent memory, selective interests, and strong analytical skills. These traits indicate that a child may be delayed in speech development but still highly intelligent. The child’s brain may already be genetically programmed for learning, including language acquisition. Language develops through multiple aspects, particularly stimulation from the surrounding environment. Understanding the brain's functions and mechanisms can help parents support their child’s language development.
2.3. Autism Spectrum Disorder
Many parents wonder: Is delayed speech a sign of autism? In some cases, delayed speech is more than just a delay—it can be a symptom of underlying conditions, the most common being autism spectrum disorder (ASD). Parents should remain vigilant and monitor their children closely. Understanding autism and recognizing early signs is crucial for timely diagnosis and treatment. Parents should consult healthcare professionals promptly to develop effective intervention strategies if any symptoms are detected.
3. Measures to Support Children with Delayed Speech
3.1. Avoid Imitating the Child’s Speech
Children with delayed speech often mispronounce words, and some may even have a lisp. The first principle parents should follow is not to imitate the child’s way of speaking, as doing so can reinforce incorrect habits that become harder to fix over time, leading to more frequent mispronunciations and lisping.
Children who are slow to speak mostly pronounce incorrectly, and some even slurred. The first rule that parents need to apply is not to imitate the way the child speaks, because this will make the child form a habit that is difficult to correct.
3.2. Communicate at Eye Level
During communication, parents should call the child by name and encourage them to maintain eye contact. This helps capture the child’s attention, increases eye-to-eye interaction, and deepens communication engagement. Consistently practicing this activity helps the child develop communication habits and positive responses. Parents should speak slowly, clearly, and understandably, always addressing the child by name and requesting eye contact. Key principles to apply when communicating with a child with delayed speech:
- Teach the child to pronounce individual sounds, starting with vowels and then moving to consonants.
- Use the 2/1/2 method, which means breaking sentences into slow, rhythmic segments. For example: "Take/give Grandma/a bowl." This method helps the child understand and respond better to requests.
3.3. Use Toys to Teach Language
Using toys as teaching tools is an effective method to help children with delayed speech. Parents can buy toys like animals or aquatic creatures and play with the child while pointing to the toys and naming them. This helps the child connect language with objects, remembering both the shape and the name of the item. This is one of the simplest and most effective ways to teach speech at home.
3.4. Use Flashcards to Stimulate Speech
Parents can use flashcards featuring fruits, animals, flowers, etc., pointing to the images and saying the names aloud for the child to hear. Teach simple words like "chicken," "fish," "tree," "fruit," and "house,"… This learning method stimulates the child’s interest, as the colorful flashcards are visually appealing.
3.5. Allow the Child to Process Information
When giving instructions, parents should allow the child some time to process the information. Wait 5-10 seconds for the child to respond. If the child cannot perform the task, demonstrate the action for them. Repeat this process in various situations to help the child gradually understand and respond.
3.6. Enroll the Child in Classes or Daycare
In a classroom setting, children are required to manage many tasks independently, such as eating, drinking, asking to use the restroom, and interacting with peers. These situations naturally encourage the use of language, which can help resolve delayed speech issues.
3.7. Avoid Electronic Devices
Do not allow children to use electronic devices like TVs, iPads, or phones, as these are significant contributors to reduced communication skills and delayed speech.
3.8. Talk to the Child More
The simplest way to improve a child’s speech ability is to talk to them more frequently or read stories aloud to them. Parents should spend time playing with the child and exploring new things together. This approach helps the child learn communication skills and reduces speech delays.
Delayed speech is a common issue that worries many parents. While early or late speech development does not affect a child’s intelligence, it can sometimes indicate conditions such as autism or Einstein's Syndrome. Parents should seek medical advice if they notice signs of delayed speech to receive proper guidance and intervention strategies.
If the suggested measures do not improve the child’s condition, parents should take the child for a comprehensive medical examination. In some cases, hearing tests may be necessary, as undiagnosed hearing problems can hinder speech development.
