Reading Aloud Slows Reading Speed—Here’s Why (and When It’s Still Worth It)
Does reading aloud slow reading speed? True or false?
True, in general. Reading aloud is usually slower than reading silently because spoken words require physical articulation. A major 2019 review of reading-rate studies found averages of about 183 words per minute aloud, compared with 238 words per minute silently for English nonfiction. That is a difference of approximately 23% relative to the silent-reading average. Individual rates vary, and slower does not necessarily mean worse comprehension or learning.
| Reading method | Research-based average | Typical purpose |
|---|---|---|
| Reading aloud | 183 words per minute | Pronunciation, performance and selected memory tasks |
| Silent nonfiction reading | 238 words per minute | Reading and studying longer passages |
| Silent fiction reading | 260 words per minute | Reading stories at a comfortable pace |
These are group-level estimates, not targets every student or adult should achieve.
The first time I tried to “speed-read” Harry Potter out loud to my dog, I discovered two things: my terrier is a terrible audience, and reading aloud slows reading speed—big time. That five-hundred-page adventure stretched longer than a Quidditch match in extra-time. Today, let’s dig into why your voice puts the brakes on your page-turning pace, what the research really says, and how to strike a smart balance between silent skimming and spoken storytelling.
Why Speaking Your Words Automatically Slows You Down
When you read out loud, you’re not just using your eyes—you’re throwing your lips, tongue, lungs, and even your breath into the mix. Those extra steps add measurable delay. Researchers call this the motor-articulatory bottleneck: your vocal tract can only articulate about two to three words per second, even if your brain is ready for more. (ScienceDirect)
Silent readers may also experience subvocalization, or inner speech, but this is not the same as speaking every word out loud. Inner speech can support language processing and remembering the order of words. Trying to suppress it does not reliably improve reading speed and may impair aspects of understanding. For example, experimental research on subvocalization found poorer detection of wording errors when articulation was suppressed, without a corresponding speed gain.
The Numbers: Silent vs Aloud Words-Per-Minute
A 2019 mega-review of reading-rate studies placed average English silent reading at ≈ 238 words per minute (wpm). Swap to oral reading and the speed sinks to ≈ 183 wpm—about 23 percent slower. (ScienceDirect)
These numbers summarize adults reading in English across many studies. They should not be treated as a fixed ceiling for sixth graders or as a diagnostic standard for individual students. Reading rate depends on age, fluency, language background, text difficulty and the task. The published review by Marc Brysbaert describes lower average rates among children, older adults and people reading in a second language.
Eye-tracking research confirms the pattern: students linger longer on each word when tasked with reading aloud, regardless of reading level or dyslexia status. (PubMed Central)

But Wait—Reading Aloud Isn’t Useless
Slower does not necessarily mean worse. In some memory experiments, words read aloud during study were remembered better than words read silently. Researchers call this the production effect, and a 2010 experimental paper explored when it occurs. This is evidence for a memory benefit in particular tasks—not proof that reading every textbook page aloud always improves comprehension.
For younger or struggling readers, oral reading also provides instant feedback on pronunciation and phrasing. Teachers can hear miscues, and students can feel rhythmic language in their mouths, deepening comprehension of complex syntax. (PubMed Central)
When Silent Reading Wins the Race
Need to blast through forty pages before the bell rings? Silent reading is your sprint. Without vocal cords throttling speed, your eyes can make larger jumps (saccades) and process text in bigger chunks, often allowing a faster pace than speaking aloud. But pushing speed too far can reduce understanding. Push too hard, and comprehension nose-dives, as speed-reading skeptics love to remind us. (WIRED)
Silent reading is also kinder to busy libraries, sleeping toddlers, and—trust me—bored terriers.
How to Read More Efficiently Without Losing Comprehension
Finger-Pacing: Use a finger or pen to help keep your place, especially in dense text. Adjust your pace to the difficulty, and check comprehension instead of forcing faster eye movements.
Phrase Practice: Notice natural groups of words, such as “in the middle of the night.” Reading for meaning may feel smoother, but deliberately skipping words or pushing your eyes faster can sacrifice understanding.
Alternate Modes: Read a paragraph silently, then whisper a tricky sentence to lock it in.
Do not force your inner voice to disappear: Humming or counting while reading can distract you and interfere with comprehension. Evidence on speed-reading techniques does not support eliminating subvocalization as a dependable way to read faster and understand just as well. Focus instead on fluent vocabulary recognition, appropriate pacing and checking whether you remember the meaning. See a 2023 study of speed-reading training.
Regular Reading Reps: Ultimately, the best way to read faster (and better) is just to read more. Practice builds vocabulary, automaticity, and confidence.
A Balanced Blueprint for Readers and Teachers
Study Sessions: Go silent for bulk intake, then summarize key ideas out loud to cement them.
Vocabulary Work: Read new words aloud first to nail pronunciation, then revisit them silently in context.
Storytime: Keep oral reading for performance, fluency drills, or shared family novels.
Assessment: Teachers can listen to a brief oral reading to gauge decoding and fluency, then ask questions or invite a retelling to check comprehension. Reading quickly is not the same thing as understanding.
The better approach is to choose a mode for the task: silent reading for efficient information gathering, reading aloud when pronunciation, practice or emphasis is more useful.
Final Thoughts (Confession Time)
Yes, reading aloud slows reading speed. But it can also slow you down in the best way—making language musical, ideas memorable, and stories communal. So the next time you need to devour a dense chapter, go silent and save your breath. When you stumble across a spine-tingling scene or a line that begs to be performed, read it aloud. Your dog might not care, but your brain—and maybe your heart—will thank you.
Happy reading, at whatever volume you choose!
Frequently asked questions about reading aloud and speed
Is “reading aloud slows reading speed” true or false?
True, generally. Speaking text adds the physical time needed to say words, so most adults read ordinary English prose faster silently than aloud. This does not make oral reading a bad learning strategy.
What is the average reading-aloud speed in words per minute?
About 183 words per minute in a large 2019 meta-analysis of English oral-reading studies. That is a research average, not a target for every reader. The review found about 238 words per minute for silent English nonfiction and about 260 for silent fiction.
Is reading aloud better for comprehension or memory?
It depends on the reader and task. Saying selected words aloud can improve memory for those words, but there is no guarantee that reading an entire long chapter aloud improves comprehension compared with reading silently at a comfortable pace.
Does stopping subvocalization make you read faster?
Not reliably. Trying to silence inner speech can interfere with processing verbal information. If your aim is better reading, test both your pace and what you understand or remember afterward.
