Does Reading While Listening to Audiobooks Improve English?

What Is Reading While Listening?

Reading while listening (RWL) means following the printed text of a story at the same time as its narrated audio, rather than listening with no text or reading with no audio. The method is distinct from the reverse pairing used in first-language reading instruction, "listening while reading" (LWR), where reading is the goal and the audio simply moves faster to keep pace with a fluent reader.

In reading while listening, listening is the goal. The written text exists to help a learner match sounds to words they already recognize on the page, build a sense of the language's natural rhythm and chunking, and avoid the word-by-word decoding that slows down a beginner's reading anyway. A 2011 study in the Asian Journal of English Language Teaching by Anna Ching-Shyang Chang describes RWL as help for learners to "match the spoken form with the written form to develop the skills of auditory discrimination and word recognition" (Chang, 2011).

Because RWL asks less of a learner than listening with no text at all, it is documented as particularly useful for learners whose listening proficiency is still low, the same learners who benefit from picking stories at the right reading level rather than unabridged native material.

Does Reading While Listening Improve English Listening Fluency?

Chang's 2011 study followed 19 EFL learners of comparable English proficiency over 26 weeks, two semesters of 13 weeks each. Seven students volunteered for the reading-while-listening treatment; the other 12 received regular classroom instruction as a control group. Both groups took the same 80-item listening test, 40 multiple-choice questions and 40 dictation items, delivered at a natural speech rate of 160 words per minute, before and after the intervention.

Chang reports that the reading-while-listening group "improved more than 100% on dictation scores, implying that RWL increased students' speed in the listening process." Dictation, writing down exactly what is heard, is a direct test of whether a learner can process spoken English at conversational speed rather than needing it slowed down, so a gain that large points at a real fluency improvement rather than a familiarity effect from the same test appearing twice.

How Much English Vocabulary Do Learners Gain From Reading While Listening?

The same study measured vocabulary with a pre- and post-intervention vocabulary levels test. The reading-while-listening group gained 17 marks on that test, equivalent to about 566 individual words. The control group, taught with regular instruction and no RWL component, gained 4 marks, about 123 words, over the same 26 weeks.

That is more than four times the vocabulary gain from a method whose stated purpose was listening fluency, not vocabulary teaching. Chang attributes part of the gap to reading volume: the treatment group read 86 books in the first 13 weeks and 156 books in the second 13 weeks, an 81% increase in quantity, and moved on to longer, more difficult books as the study progressed. More exposure to English text, at a pace a learner could follow because the audio was doing part of the decoding work, produced more opportunities to meet new words in context, the same mechanism that makes extensive reading effective for vocabulary building on its own.

How Does Reading While Listening Compare to Listening Only or Reading Only?

Separate research cited in Chang's review points the same direction. Brown, Waring, and Donkaewbua (2008) compared three modes, reading only, reading while listening, and listening only, with Japanese college students working through graded readers, and found students learned the most new words in the reading-while-listening mode. Chang's own 2009 study of Taiwanese college students found a comprehension score about 10% higher in the reading-while-listening mode than in listening only, on two short stories of matched length and difficulty.

Learner preference lines up with the outcomes. In a separate small-scale study Chang cites, 58% of students preferred reading while listening, 40% preferred reading only, and 2% preferred listening only, with students reporting that the paired mode made stories easier to follow, more interesting, and easier to concentrate on.

How Should You Start Using Audiobooks Alongside Reading?

Start with a story at a reading level that is already comfortable rather than a difficult one, since the research above measured RWL against regular graded readers, not against material a learner is struggling to parse even without audio. Choosing a story at the right level matters as much for RWL as it does for reading alone.

Play the audio at a natural pace rather than slowed down. The point of RWL is exposure to real speech rate, and slowing it down removes the fluency benefit the studies above measured. Dobi Apps' Audiobook pairs narrated audio with synchronized text across CEFR levels A1 through C2, which lets a learner move from picture-book pacing to a natural adult reading speed as listening fluency builds.

New words encountered this way are still worth reviewing deliberately afterward. Reading while listening builds fluency and exposure; locking a specific new word into long-term memory is a separate step, covered in how spaced repetition builds English vocabulary retention.

When Should You Stop Reading and Listening at the Same Time?

Chang's review notes that RWL is most valuable for learners whose listening proficiency is still developing, and that the field's broader guidance is to wean learners away from simultaneous reading and listening once proficiency rises, moving them toward independent reading or independent listening. The skill an intermediate-to-advanced learner actually needs, understanding spoken English with no text in front of them, is not the skill RWL practices.

A practical marker: once a learner can follow a graded audiobook at natural speed with the text covered and still answer basic comprehension questions correctly, independent listening practice will do more for real-world listening than continuing to read along. Until that point, the studies above show reading while listening outperforming both reading only and listening only for building the fluency that gets a learner there, the same extensive input that makes learning English through stories work in the first place. A learner who has reached that marker and wants to work on speaking next, rather than only listening, can apply the same audiobooks to shadowing practice for English pronunciation, which adds speaking the words aloud instead of only following them silently.
