Dyslexia and Auditory Processing Disorder (APD): What’s the Link?

Written By Sydney St George audiologist Melody Cao  

auditory processing disorder and dyslexia

Some parents tell me, “My child can hear the teacher, but often can’t follow instructions, and the teacher says they’re slow with reading.” If that sounds familiar, you’re not alone. Auditory Processing Disorder (APD) and dyslexia can look similar in everyday life, and they also commonly occur together.

Why APD and dyslexia can look similar

In real life, both can present as:

“Hearing but not understanding”

Struggling more in background noise (classrooms, groups, sport, restaurants)

Needing repetition (“What?” / “Pardon?”)

Listening fatigue and switching off by the end of the day

Difficulty keeping up with fast talkers, accents, or multiple speakers

Challenges with speech-sound (phonological) processing, which supports both listening and early literacy skills

Because these signs overlap, it’s easy to assume a child has only one issue—when there may be a combination of listening and literacy factors happening together.

The key differences

Although APD and dyslexia can overlap, they’re not the same.

APD is mainly listening-skill based. It describes difficulties in how the brain processes sound, especially:

understanding speech in noise or competing speech

using both ears together efficiently (binaural/dichotic listening)

processing timing cues in speech (which supports clarity, rhythm, and speech perception)

Children with APD may have a normal hearing test, but still struggle to follow spoken instructions in busy environments.

Dyslexia is primarily a word-level literacy difficulty. It affects: reading accuracy and fluency,spelling,decoding (sounding out)

linking print to speech sounds (letter–sound mapping).

A child with dyslexia may listen well in quiet, but reading and spelling remain hard work and progress may be slower even with great effort.

Reading is visual and auditory

Reading isn’t just about seeing letters on a page. The brain constantly links letters to speech sounds, so reading is both visual and auditory in nature. That’s why some children who struggle with speech-sound processing may also find reading and spelling challenging. It also explains why difficulties can show up as a mix of listening, language, and literacy concerns—especially once classroom demands increase.

When to consider an APD assessment

It may be worth exploring APD when you notice patterns like:

your child copes in quiet one-to-one settings, but falls apart in noise

they frequently mishear, miss key details, or seem “not listening”

they rely heavily on watching faces or copying peers

they become tired, overwhelmed, or anxious in busy listening situations

reading support is in place, but classroom understanding is still a major barrier

What helps: a clear profile and a team approach

The most helpful next step is working out what’s driving the difficulty—listening, language, literacy, attention, or a combination. Once we understand the profile, supports can be targeted and practical. This might include classroom strategies (seating, instruction style, reducing noise), assistive technology such as remote microphones, auditory training where appropriate, and coordinated care with speech pathology and educators for literacy support.

If you’re not sure whether your child’s struggles are “reading”, “listening”, or both, you don’t have to figure it out alone. At Melody Hear For You, we provide APD assessments and clear, family-friendly recommendations that focus on improving day-to-day listening, learning, and confidence.
