When Reading Is Hard, Audio Can Keep Learning Moving

Make space for the idea

For a learner with dyslexia, decoding written words can take substantial effort. When a lesson depends on reading, that effort may leave less attention for understanding the subject. Audio can offer access to an explanation while a student follows the accompanying text or diagram.

A meta-analysis by Wood and colleagues found a positive average effect of text-to-speech and related read-aloud tools on comprehension for students with reading disabilities. Results varied across studies and learners. The evidence supports trying audio as an accommodation; it does not mean every child or every audio program will benefit equally. Read the research.

Support access and teach reading

Listening to an explanation and learning to decode words serve different purposes. A student can use audio to explore age-appropriate ideas while continuing explicit reading and spelling instruction. The International Dyslexia Association recommends structured literacy for students with dyslexia, including systematic instruction in sound–symbol relationships and language structure. See the IDA guidance.

For families, this can mean making two plans: one for building reading skills, and another for making today’s science, history, or math lesson accessible. Our guide to structured literacy is a useful place to start with the first.

What that can look like in algebra

Our sister program, Vector Mountain, teaches Algebra 1 through short videos, audio explanations, and interactive practice. Students can ask Vector, an AI guide, questions out loud and receive spoken explanations alongside worked math. They can also write their work and get feedback in the same learning environment.

For a student who finds long written explanations tiring, that combination offers another route into the math. This is an application of the access principle, rather than evidence that Vector Mountain improves reading: the research above did not evaluate Vector Mountain, and an algebra program does not replace structured literacy instruction.

Try one lesson, then listen to your learner

1. Choose a short lesson on a familiar topic and watch it together.
2. Pause after a worked example. Ask your student to explain the next step in their own words.
3. Invite them to replay the explanation, look at the visual, or write it out. Let them choose what helps.
4. Notice understanding and frustration, not just time spent. A useful support should make the learning more accessible.

Students without a dyslexia diagnosis can try the same routine. Preferences and needs differ, so use the learner’s experience to guide what you keep.
