Definition

Speech delay refers to a condition in which a toddler or child has not attained the expected stage of speech development for their age compared to peers of the same age group. Speech involves the verbal expression of language, encompassing articulation (the ability to form sounds and words). 

A toddler experiencing speech delay may encounter difficulty accurately forming the correct sounds to articulate words. They might exhibit symptoms such as stuttering or difficulty pronouncing words accurately.

The most prevalent type of speech delay doesn’t hinder a child’s understanding or non-verbal communication. Various factors, such as congenital hearing loss, neurological disorders impacting the nerves, or underlying developmental conditions, can contribute to speech delay.

Causes

Speech delays can result from various issues, such as:

• Problems with the mouth, tongue, or palate:

This may include conditions like ankyloglossia, commonly known as tongue-tie, where the tongue is tethered to the floor of the mouth. This condition can pose challenges in producing certain sounds, especially : D, L, R, S, T, Z, and TH.

• Lack of stimulation 

Effective language learning is hindered when a child lacks communication stimulation and encouragement. The environment plays a crucial role in speech and language development. Instances of abuse, neglect, or insufficient verbal stimulation can impede a child’s progress in reaching typical developmental stages. 

• Exposure to more than one language 

Children may experience mild speech delay during toddlerhood; however, it’s generally uncommon for these delays to persist by the time they reach school age. Multiple language exposure does not typically lead to long-term delays. 

•  Disorders of the muscles that control speech (dysarthria)

• Hearing loss

Hearing loss in children may result from severe middle ear infections, certain medications, trauma, or genetic disorders.

• Neurological disorders

Some neurological conditions, including cerebral palsy, muscular dystrophy (progressive muscle weakness), or traumatic brain injury, can impact the muscles essential for speech.

• Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder encompasses a group of neurological disorders characterized by potential impairments in communication, social interaction, and cognitive skills.

• Intellectual Impairment

 If your child is not yet talking, it is important to consider that the delay may be linked to cognitive issues rather than a simple inability to form words. 

• Without an identifiable cause.

Risk Factors

Several factors may increase the risk of delayed speech development in children, including

• Premature birth
• Genetic conditions such as Down syndrome or muscular dystrophy
• Poor hearing
• Malnutrition
• Maternal use of drugs or alcohol during pregnancy 
• Abuse or neglect
• Lack of oxygen during childbirth

Symptoms

Children follow unique growth patterns, and a slight delay in speech does not always indicate a serious issue. There’s no strict time frame for a child to start speaking or using complete sentences. However, most children reach specific stages in speech and language by certain ages. 

Here are the stages of typical child speech development. Understanding these stages can help parents monitor their child’s progress: 

By the end of 3 months of age, your child mau exhibit the following milestones:

• Smile when you appear
• Make buzzing sounds
• Be quiet or smile when spoken to
• Show signs of recognizing your voice
• Demonstrate different crying patterns for various needs. 

By the end of 6 months of age, your child may achieve the following milestones:

• Make sounds like gargling when playing or being alone.
• Babble and produce a variety of sounds.
• Use their voice to express pleasure and displeasure.
• Move their eyes in the direction of sound.
• Respond to changes in the pitch of your voice. 
• Recognize that some toys make sounds
• Notice and react to the sound of music.

By the end of 12 months of age, your child may reach the following milestones: 

• Attempt to imitate spoken sounds.
• Utter words like “dada,” “ mama,’’ and ‘’Uh-oh.”
• Comprehend simple instructions, such as ‘“ Come here.”
• Recognize words for common items, like “ shoes.
• Turn and look toward the source of sounds. 

By the end of 18 months of age, your child may achieve the following milestones:

• Recognize names of familiar people, objects, and body parts.
• Follow simple instructions accompanied by gestures.
• Begin to say as many as 10 words. 

By the end of 24 months, your child may achieve the following milestones: 

• Use simple phrases, such as “drink milk.”
• Ask one -to two-word questions.
• Follow simple commands and understand simple questions.
• Be able to say about 50 words or more.
• Be able to speak well enough to be understood at least half the time by you or another primary caregiver.

By the age of 3, children typically demonstrate the following language abilities: 

• Speak in short sentences
• Identify body parts
• Use plural words

By the age of 4, children typically demonstrate the following language abilities: 

• Can tell simple stories and remember short nursery rhymes
• Use sentences of five words
• Use the words “I” and “ You “ correctly

By the age of 5, children typically demonstrate the following language abilities: 

• Able to understand two-part commands with prepositions ("under" or "at")
• They can confidently articulate their first and last name.
• Ask questions like “Why?” or “Who?”
• They develop the ability to share details about their daily experiences.

 If a child's speech development does not reach certain stages according to age, then the child may be experiencing speech delay. Here are some symptoms of speech delay in children:

•  At 2 months of age, does not make a sound or produce a sound
• At 18 months, they cannot use simple words such as "mama" or "dada."
• At the age of 2 years, cannot use at least 25 words
• At 2.5 years old, cannot yet use unique two-word phrases or noun-verb combinations
• At 3 years old, cannot use at least 200 words, does not ask for things by name, has difficulty understanding words even if you stay with him/her
• At any age, unable to say previously learned words

Diagnosis

In diagnosing a speech delay, the doctor initiates an insightful interview with the parent or caregiver, delving into the child's speech and language proficiency and assessing various developmental and behavioral milestones. A comprehensive physical examination follows, including a thorough check of the child's mouth, palate, and tongue. Hearing capabilities are also evaluated. Based on the initial findings, the doctor may recommend additional supportive tests, such as audiology assessments and a comprehensive nervous system examination, to ensure a comprehensive and accurate diagnosis."

Management

Speech delay management may,  include: 

Speech Therapy

First-line treatment is speech therapy. If speech is the only developmental delay, this therapy may be the only treatment required. With early intervention, your child may have normal speech when they enter school. A speech therapist will work directly with your child and instruct you on how to help.

Treating the underlying condition

 If another underlying condition causes the speech delay, it's important to address that issue as   well, such as

• Treating hearing problems
• Correcting physical problems with the mouth or tongue,
• Occupational therapy
• Physical therapy
• Treating nerve disorders

Complications

Addressing speech delay promptly is crucial, as untreated delays can adversely impact a child's future development. Studies indicate that speech and language delays between 2.5 and 5 years old may contribute to reading challenges during primary school. Furthermore, untreated speech delays can affect a child's behavior and hinder their socialization with peers. Early intervention is key to mitigating these potential challenges and fostering a child's well-being. Parents and caregivers should proactively seek professional guidance if they observe signs of speech delay in their child.

Prevention

Here are some things parents can do to help their child's speech development and prevent the onset of late speech:

• Talk directly to your child, even to tell them what you're doing.
• Use gestures and point to objects as you say their names
• Read and tell stories to your child often
• Sing simple songs that are easy to repeat
• Give your full attention when talking to your child, and try to be patient when your child tries to talk to you.
• When someone asks your child a question, let the child try to answer it themselves.
• Give your child a chance to say what he needs himself
• Repeat words correctly instead of immediately criticizing the child's mistake in pronouncing a word
• Let the child interact with children who have good language skills
• Ask questions, give choices, and allow plenty of time for your child to respond

When to see a doctor

Consult a doctor if your child has symptoms of delayed speech and if he/she has not reached the age-appropriate stage of speech development.
