Many parents are surprised when their child struggles with spelling despite spending hours practicing sight words. What they may not realize is that speech production and spelling skills are closely connected.

If your child has difficulty pronouncing certain sounds or has a history of a speech sound disorder, those same challenges can affect how they learn to read and spell. Understanding this connection can help parents seek the right support early and prevent future academic frustration.

Why Speech and Spelling Are Connected

Learning to spell isn’t just about memorizing words and spelling rules. Children must be able to hear, identify, and manipulate individual sounds, or phonemes, in words before they can accurately match those sounds to letters.

For example, when spelling the word ship, a child needs to recognize that it contains three sounds: /sh/, /i/, and /p/.

If a child cannot clearly hear or produce one of these sounds, spelling becomes much more difficult.

This is why speech and language pathologists often assess both speech sound production and phonological awareness when evaluating children with speech or literacy concerns.

How Speech Sound Disorders Affect Spelling

Children with speech sound disorders may:

  • Leave sounds out when spelling (e.g., “pane” for plane)
  • Substitute one sound for another (e.g., “tat” for cat)
  • Confuse similar sounds like /f/ and /th/
  • Have difficulty hearing subtle differences between speech sounds
  • Rely on memorization rather than understanding sound-letter relationships

Spelling errors often mirror the speech errors the child uses when talking.

For example:

Speech errorPossible spelling error
Says “wabbit” for “rabbit”Spells rabbit as wabbit
Says “poon” for “spoon”Spells spoon as poon
Says “tar” for “car”Spells car as tar

As speech improves, spelling often becomes more accurate because children develop stronger awareness of the sounds within words.

Phonological Awareness: The Missing Piece

One of the strongest predictors of future reading and spelling success is phonological awareness.

This includes skills such as:

  • Rhyming
  • Identifying beginning and ending sounds
  • Breaking words into individual sounds
  • Blending sounds together
  • Deleting or changing sounds in words

Children with speech sound disorders are at increased risk for weaknesses in phonological awareness, which can make both reading and spelling more challenging.

Phonological awareness skills can be taught and strengthened.

Does Every Child With Speech Errors Have Spelling Problems?

No. Many children with mild articulation errors, such as difficulty saying /r/ or /th/, become excellent readers and spellers.

The greatest concern is for children who have:

  • Multiple speech sound errors
  • Difficulty producing many different sounds
  • Trouble understanding how sounds work within words
  • A history of delayed speech and language development
  • Ongoing reading or writing struggles

How Speech Therapy Can Improve Spelling

Speech therapy does much more than teach children how to pronounce sounds correctly. Effective therapy also strengthens the skills that support literacy by helping children:

  • Hear the individual sounds in words
  • Notice differences between similar sounds
  • Connect speech sounds to letters
  • Build phonological awareness
  • Improve overall language skills

Many speech-language pathologists intentionally incorporate early literacy activities into speech sessions because of the strong connection between spoken and written language.

What Parents Can Do at Home

Parents play an important role in supporting both speech and spelling development.

When Should You Seek a Speech Evaluation?

If your child is difficult to understand, continues to make speech errors beyond the expected age, or is struggling with both speech and spelling, a speech and language evaluation can help identify the underlying cause.

Early intervention is important. Addressing speech sound difficulties and phonological awareness together can improve not only speech production and intelligibility but also reading, spelling, and overall academic confidence.

Final Thoughts

Speech production and spelling are more connected than many people realize. Children learn to spell by listening to, recognizing, and organizing the sounds they hear in spoken language. When speech sound production skills are weak, spelling often becomes more difficult.

The encouraging news is that with targeted support, children can strengthen both their speech and literacy skills. Whether through speech therapy, phonological awareness activities, or consistent practice at home, building a strong foundation in spoken language sets the stage for success in reading and spelling for years to come.
