As young children, part of our development process is learning how to say words correctly. These speech skills develop overtime as we learn to talk. Some sounds come easy, like the letters p, m, or w. Others are more difficult, such as z, sh, or th.

By the age of five, most children can pronounce almost all types of speech sounds. However, when a child struggles to say words or sounds correctly, this can be a telltale sign of a speech sound disorder.

What is a speech sound disorder?

Children who are not able to pronounce certain sounds or words by an expected age may have a speech sound disorder. Speech sound production requires both the knowledge of a speech sound, as well as the ability to coordinate the jaw, tongue, and lips with breathing and vocalizing in order to produce the desired sound. It is often difficult to understand someone with a speech sound disorder and, in many cases, it can affect a person’s social, academic, and professional development.

Broadly speaking, there are two types of speech sound disorders: articulation disorders and phonological process disorders.

Articulation Disorders: This is the inability to form legible words past a certain age. Word sounds may be distorted, added, dropped, or swapped altogether. According to Stanford Children’s Health, some common signs of an articulation disorder can include:

  • Errors due to differences in the orofacial structures (example: “hip” instead of “ship”)
  • Distorting sounds in words (example: saying "thith" instead of "this")
  • Swapping sounds in words (example: saying "wadio" instead of "radio")

Phonological Disorders: You or your child may have a phonological process disorder if there’s a regular pattern of mistakes common among certain words. While this is common in children, if it extends past a certain age you or your child may be at risk. Signs of a phonological process disorder can include:

  • Saying only one syllable in a word (example: "bay" instead of "baby")
  • Simplifying a word by repeating two syllables (example: "baba" instead of "bottle")
  • Leaving out a consonant sound (example: "at" or "ba" instead of "bat")
  • Changing certain consonant sounds (example: "tat" instead of "cat")

While all children develop at different speeds, there are certain sounds they should be able to make by certain ages. According to the American Speech-Language-Hearing Association (ASHA), the chart below shows the ages when most English-speaking children should develop certain sounds.

By 3 months:

  • Makes cooing sounds

By 5 months:

  • Laughs and makes playful sounds

By 6 months:

  • Makes speech-like babbling sounds like puh, ba, mi, da

By 1 year:

  • Babbles longer strings of sounds like mimi, upup, bababa

By 3 years:

  • Says m, n, h, w, p, b, t, d, k, g, and f in words
  • People familiar with the child can understand their words

By 4 years:

  • Says y and v in words
  • May still make mistakes on the s, sh, ch, j, ng, th, z, l, and r sounds
  • Most people understand the child’s speech

It’s important to realize that adults too can struggle with speech sound disorders. Some adults have problems that were started as a child and never properly treated, causing them to persist overtime. Others may have been the development of a stroke or traumatic brain injury.

Note: Having an accent is not a speech sound disorder. While the mispronunciation of certain sounds and words can sound like a speech problem, it may simply be a result of an accent.

Causes of Speech Sound Disorders

It can be hard to determine the root cause of a speech sound disorder, and there can be several factors involved. Unfortunately, in many cases there is no known cause. It other cases, speech sound errors may be caused by:

  • Brain damage, such as a head injury
  • Intellectual or developmental disability, such as autism
  • A genetic disorder, such as Down Syndrome
  • Problems with hearing or hearing loss, such as a history of ear infections
  • Physical abnormalities that affect speech, including cleft palate or cleft lip
  • Disorders affecting the nerves involved in speech

Apraxia and dysarthria are two other conditions that can cause speech problems. In childhood apraxia of speech, the brain has trouble sending signals to the speech muscles, like the lips, tongue, and throat, which can affect how and when they move. With dysarthria, the speech muscles may be weak and unable to produce certain sounds.

How are speech sound disorders diagnosed?

As with any condition, you should contact your physician if you suspect signs of a speech sound disorder. Mostly likely they will start by checking your child’s hearing. Many children with hearing loss are unable to properly listen to the words and sounds they make.

If your children’s healthcare provider rules out hearing loss, you should speak with a certified speech-language pathologist. By watching and listening to your child, they can determine whether or not he or she has a speech sound disorder.

As with any speech or language disorder, earlier interventions often lead to better outcomes. This is why it’s important to get your child seen by a speech-language pathologist sooner than later. The speech-language pathologist will work with you and your child to:

  • Evaluate your child’s speech and language skills
  • Look at how your child moves their lips, jaw, and tongue
  • Provide education and preventative exercises so the condition doesn’t worse
  • Develop a treatment plan to overcome speech challenges.

How Can Teletherapy Help with Speech Sound Disorders?

As mentioned above, working with a speech-language pathologist can help diagnose and treat speech sound disorders. If your healthcare provider recommends speech therapy, working with an online speech therapist can provide several financial and convenience advantages over more traditional in-practice settings.

  • Teletherapy is More Affordable
    Practices have to pay for a lot of expenses that aren’t directly related to patient care - facility costs, marketing, support staff. With teletherapy, these cost savings are passed down to the customers.
  • Flexible Scheduling and Convenience
    Instead of spending time traveling to and from in-person therapy sessions, patients can schedule and attend appointments from the comfort of their own home. Patients also have greater flexibility to schedule sessions on the dates that work best, and at the times that they prefer.
  • Just as Effective as Traditional Therapy
    Because all Expressable therapists are licensed Speech Language therapists, there’s no difference in quality between teletherapy and on-site therapy sessions. A landmark study from Kent State University showed that there was no significant difference in scores between students who participated in teletherapy versus on-site therapy.
