Preface
A dyslexic reader can read. That is worth saying at the top, because the word arrives loaded with the wrong assumption. What costs so much is decoding: turning the shapes on the page into sounds and words fast enough that the meaning survives the journey.
Here is what that cost looks like on a Tuesday afternoon. You get to the end of a paragraph and realise none of it landed. You go back to the top and do it again. On the third pass the sentence finally means something. By then you have spent four minutes on one paragraph, a colleague read the same page in forty seconds, and there are eleven pages left.
Read-aloud changes that arithmetic. When you hear the words at the same time as you see them, the decoding is handled for you, and your attention goes where it was always supposed to go, which is the meaning of the sentence.
This is a guide to using read-aloud as a working reading tool rather than a novelty. It is written for dyslexic adults and students, and for the parents, teachers, and workplace access advisers who help them set things up. Nothing here is medical, clinical, or educational-assessment advice, and Yaps is not a diagnosis tool, a treatment, or a medical device. It is a way of getting text into your head with less friction.
Why Hearing and Seeing Together Works
Reading a page is two jobs stacked on top of each other. The first is decoding, which is working out what the marks say. The second is comprehension, which is working out what they mean.
For most people the first job is so automatic it feels like it does not exist. For a dyslexic reader it is effortful, and effort has to come from somewhere. It comes out of the budget for the second job. That is why the fourth pass over a paragraph often works: the decoding got easier through repetition, so there was finally some attention left over for the meaning.
Read-aloud takes the first job off your plate. Someone else does the decoding, out loud, at a steady pace, and everything you have goes to comprehension. This is not a claim that read-aloud improves reading ability, fluency, or any measurable outcome, and we are not going to make that claim. It is a claim about where your attention goes in the next ten minutes, which is a much more ordinary and much more useful thing.
So why not just listen, with the screen off? Because for a lot of readers the audio alone is worse. Your eye has nowhere to go, you drift at the second subordinate clause, and you lose your place with no way of finding it again. The version that tends to work is both at once: the voice carrying the line and your eye following it.
Without Yaps
The fifth pass at one paragraph
You read it, take in nothing, and start again. Your finger holds the line so you do not lose it. Four minutes gone on ninety words, and the tiredness carries into the next page, so the next page takes longer still. Long documents get skimmed or quietly abandoned.
With Yaps
One pass, following the highlight
Select the paragraph and press the read-aloud hotkey, and it is read to you where it sits. Open that reading in the Yaps reader and the words light up one by one as they are spoken, so your eye is carried along the line instead of holding it. Slow the voice to 0.75x where the writing is dense. One pass, and it stays in.
The Part That Actually Matters: Read-Along Highlighting
Most write-ups of text to speech stop at "it reads your text out loud", which misses the feature that does the work.
Yaps has a reader view built for exactly this. Open a reading, a note, or a Studio transcript in it, and the text highlights word by word as the voice moves through it. The word being spoken is marked on screen, and the marker travels along the line in time with the audio. Where word level timings are not available, it falls back to highlighting sentence by sentence, so you always know which sentence you are in even when the finer tracking is not possible.
That sounds like a small visual flourish. It is the opposite. It is the thing that keeps ear and eye locked together, and it fixes three specific failures at once.
You stop losing your place. No finger under the line, no re-finding where you were after a distraction, no reading the same line twice because the eye slipped down. The highlight is the place holder, and it moves on its own.
Sound and shape land at the same moment. You hear the word and see the word in the same instant. For readers who find a word easy to understand by ear and slow to unpick by eye, that pairing is the whole point of the exercise.
You can look away and come back. Somebody speaks to you, the phone buzzes, you look up. When you look back, the highlight tells you exactly where the voice has got to, and you rejoin without rewinding.
The practical version is unglamorous, and it comes in two shapes. When you only need to hear something, select the text wherever you are already reading it and press the read-aloud hotkey: the voice starts on that selection, with nothing to paste and no import step. When you want to follow along as well as listen, open that reading in the Yaps reader and watch the highlight travel. Your own notes and your Studio transcripts open in the same reader.
Speed Is a Reading Tool, Not a Setting
The second thing that decides whether read-aloud works is the speed control, and it is usually treated as an afterthought.
Yaps offers presets at 0.75x, 1.0x, 1.25x, 1.5x and 2.0x. Most guides talk about the fast end, because listening to a book at double speed sounds impressive. The useful end for hard reading is the slow one.
At 0.75x, a dense paragraph stops outrunning you. Legal wording, a lease, a methods section, a set of assembly instructions with four numbers in one sentence: these are the places where a normal speaking pace hands you the next clause before you have finished with the last one. Dropping a quarter off the speed is often the entire difference between following a paragraph and losing it.
The fast end has its own job. Skimming a long report to find the two paragraphs that matter to you, or getting through a piece of background reading you already half know, both go faster at 1.5x or 2.0x than they would by eye.
The habit worth building is changing speed as you go rather than picking one and living with it. Fast through the introduction you do not need, slow through the three sentences that carry the argument. That is what a confident reader does naturally with their eyes, and the speed control is how you do it with your ears.
How to Read Along With Yaps in Five Steps
The whole loop takes about five minutes to set up once, and a couple of seconds every time after that.
Install Yaps on the computer3 min
Windows, macOS, or Linux. Read-aloud runs on the machine itself, so the document never leaves it.
Select the text where it already is2 sec
A web page, an email, a document, a note. No pasting into a separate reading app.
Press the hotkey, then open the reader1 sec
The voice starts on your selection. In the Yaps reader the words light up one at a time, so your eye is carried along the line.
Match the speed to the material2 sec
0.75x for dense writing, 1.5x or 2.0x for skimming. Change it mid-paragraph if you need to.
Keep the audio if it is long1 min
Save the reading as a WAV file and play the chapter back on the bus, with no app and no signal.
- Install Yaps on your computer. Windows, macOS, and Linux all work. The desktop app opens into a 7-day free trial, which does require an account.
- Select the text where it already lives. A web page, an email, a shared document, a note of your own.
- Press the read-aloud hotkey. The voice begins on your selection, and in the Yaps reader the highlight moves along the line word by word.
- Set the speed for the material. 0.75x when it is dense, 1.5x or 2.0x when you are skimming.
- Save it as audio when the document is long. A WAV file you can play back later, anywhere, offline.
Nothing You Read Leaves the Machine
There is a reason this matters more for reading support than for most software categories, and it is not abstract.
Think about what you actually want read aloud. A diagnosis letter. A tenancy agreement. A settlement offer from an employer. A message from a solicitor. A set of exam access arrangements. A first draft of something you are not ready for anybody to see. The documents that are hardest to read are very often the ones that are most private, and that is not a coincidence: they are hard because they are dense, and they are dense because they are consequential.
Most reading tools with good voices are cloud services. The text is sent to a company's servers, turned into audio there, and streamed back. That is a reasonable engineering choice and it produces good results. It also means the tenancy agreement went to a third party before you heard a word of it.
Yaps read-aloud runs on your own device. The text is turned into speech on the machine in front of you, so nothing is uploaded and no account of what you read exists anywhere. The practical consequences follow immediately: it works on a train with no signal, in a building with locked-down wifi, in an office where uploading client documents to a website would be a disciplinary matter, and on a plane.
The document you most want read aloud to you is usually the one you least want uploaded to somebody else.
Yaps
Reading in a Second Language
Dyslexia does not confine itself to one language, and plenty of people read daily in a language that is not their first.
On desktop, Yaps reads text aloud in 31 languages, all of it offline: English, Korean, Japanese, Arabic, Bulgarian, Czech, Danish, German, Greek, Spanish, Estonian, Finnish, French, Hindi, Croatian, Hungarian, Indonesian, Italian, Lithuanian, Latvian, Dutch, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Swedish, Turkish, Ukrainian, and Vietnamese.
That combination is rarer than it should be. Offline readers have historically been English only, and multilingual readers have historically been cloud services that want your text first. Hearing a French set text, a German contract, or a Polish letter read aloud, with the words highlighted as they are spoken, and none of it leaving your laptop, is a genuinely useful thing to have. We went through the wider picture in multilingual text to speech that works offline. The 31 language figure is a desktop number: mobile ships a smaller set of voices.
Turn a Long Document Into Audio You Keep
Read-along is for the reading you do at a desk. Some reading is not like that.
On desktop, a reading can be saved as an audio file in WAV format. A forty page report, a chapter, a set of course notes, or a policy document becomes something you can play on a phone, a speaker, or a car stereo, with no app and no connection. You listen once on the walk in, then read along at the desk for the sections that matter, which is a far better use of an hour than a single grinding pass by eye.
That workflow deserves its own walkthrough, and it has one: see turning a PDF into an audiobook. One warning belongs here though. Yaps does not do OCR, which is the technology that recognises letters inside a picture. If your PDF is a scan or a photograph of a page, it is an image as far as any software is concerned, and it has to be made searchable by another tool before Yaps can read it. Text in a web page, an email, a document, a note, or a text based PDF is fine.
What Yaps Does Not Do
Four limits, stated plainly, because a reading tool that oversells itself wastes your afternoon.
Yaps is not a screen reader. A screen reader narrates the entire interface: which button is under the cursor, what a menu contains, when a notification arrives, and how to move around a screen without seeing it. Yaps reads text you select. If you need full interface narration, use the real thing, which is already installed and free: VoiceOver on Mac, iPhone, and iPad, TalkBack on Android, and Narrator on Windows. Those are mature tools, and Yaps sits beside them rather than replacing them.
Yaps does not do OCR. A scanned or photographed page must be made searchable first. This is worth knowing before you hand somebody a folder of scanned handouts.
Yaps has no dyslexia-specific reading fonts or coloured overlays. Some readers find a particular typeface, a wider letter spacing, or a tinted background helps. Yaps does not restyle other applications, so if that is central to how you read, a dedicated assistive reading suite will serve you better on that specific point, and several of them combine OCR, fonts, and overlays in one package. The Yaps Android keyboard does offer its own themes and fonts, but that is for typing rather than for reading text elsewhere.
There is no iOS app yet. Yaps runs on Android, Windows, macOS, and Linux today, with iOS coming soon. The 31 languages, the speed presets, and the audio export are desktop features.
None of this is clinical advice. Yaps is not a diagnosis tool, an intervention, a treatment, or a medical device, and it makes no claim to improve reading ability or fluency. Assessment, access arrangements, and formal support are matters for qualified professionals.
Yaps Against the Alternatives
Three realistic categories of tool exist for this job. Here is the honest comparison.
| What matters | Yaps | Built-in OS read-aloud | Cloud reading apps |
|---|---|---|---|
| Word by word highlighting | Yes, with sentence fallback | On some platforms only | Usually yes |
| Runs on your device | Yes | Usually yes | No (cloud) |
| Works with no internet | Yes | Varies by voice | No |
| Text never uploaded | Yes | Depends on the voice | No, text is sent |
| Speed presets | 0.75x to 2.0x | Yes, a slider | Yes |
| Save the reading as an audio file | Yes, WAV on desktop | Rarely | Sometimes, on paid tiers |
| Offline languages | 31 on desktop | Varies, downloads needed | Many, but online |
| OCR of scanned pages | No | No | Often yes |
| Dyslexia fonts and overlays | No | Partly, system settings | Often yes |
| Narrates the whole interface | No, use a screen reader | Yes, screen reader built in | No |
| Also handles dictation | Yes, on-device | Yes, varies | Usually reading only |
Read the OCR and font rows as real limits rather than small print. If your reading is mostly scanned handouts, or a tinted overlay is the thing that makes text usable for you, a dedicated assistive suite covers those and Yaps does not.
Everywhere else, Yaps is the better default: word level highlighting with a sentence fallback, five speed presets, 31 offline languages on desktop, an audio export you keep, and no version of your document sitting on somebody else's server. Built-in OS read-aloud is the sensible free starting point and worth trying first, particularly on iPhone, where Yaps is not available yet. See text to speech for the full feature detail.
For Parents, Teachers, and Access Advisers
If you are setting this up for somebody else, three things are worth doing differently.
Hand the keyboard over immediately. Do not demonstrate for ten minutes. Let them select their own text and press the hotkey on the first attempt, because what has to be learned is the doing, not the watching.
Use their real reading, not a sample. The set text they are behind on, the actual policy document, the email they have been avoiding. A demo paragraph teaches nobody whether this works for them.
Set the speed low and leave it there for a week. The most common way this fails is a first session at 1.5x, a lost thread, and a decision that read-aloud is not for them.
One more note for anybody advising an adult at work. The private, on-device part is not a nice-to-have in that setting. It is often the only reason a reading tool can be approved at all, because uploading client files, patient information, or commercial documents to a third-party website is usually forbidden outright. A tool that never sends the text anywhere sidesteps that conversation.
Getting Words Out Is the Other Half
This post is about taking text in. The opposite direction, getting your own words down without fighting spelling and the blank page, is a separate job with separate tools, and we covered it properly in the best dictation software for dyslexia.
The short version is that they pair well. Dictation puts your thinking on the page in your own words at speaking pace, with the filler words and false starts cleaned up on the device. Read-aloud then reads that draft back to you in the reader, highlighted word by word, which is by some distance the fastest way to catch a sentence that went wrong. Writing and proofreading, both by ear, both offline.
The same combination helps outside of study and work entirely. Long articles, letters from officialdom, and forms are easier heard than read, which is exactly why we recommended the same two features to a very different audience in the best AI app for seniors.
The Bottom Line
If reading long text is expensive for you, make Yaps the default and build two habits on day one. Open the reading in the Yaps reader so the words highlight as they are spoken, and drop the speed to 0.75x until following the highlight is second nature. Then use it on real reading, not samples.
You get 31 offline languages on desktop, five speed presets, a WAV export for the documents you would rather walk around with, and the guarantee that the lease, the letter, or the draft never went anywhere near a server.
Two honest exceptions. If your reading is scanned pages, get OCR from a dedicated assistive suite first, because Yaps cannot read a picture of words. If you need the whole interface spoken rather than text you select, use VoiceOver, TalkBack, or Narrator, and run Yaps beside it for documents. Otherwise the answer is not complicated: select the text, press the hotkey, and follow the highlight in the reader.
Frequently Asked Questions
Does text to speech help with dyslexia?
Many dyslexic readers find it helps because it removes the decoding work, which is the expensive part. When a voice turns the letters into words for you, the attention you were spending on shapes goes to meaning instead, and hearing the words while seeing them keeps both channels together. This is a workflow benefit rather than a treatment: text to speech is not an intervention, it makes no claim to improve reading ability, and whether it suits a particular reader is something to try rather than assume.
What is the best text to speech app for dyslexia?
Yaps is the strongest default for most people, because it does the two things that decide whether read-aloud is usable: its reader view highlights the text word by word as it reads, and it lets you slow the voice to 0.75x or speed it to 2.0x. It reads 31 languages offline on desktop, saves a reading as a WAV audio file, and runs entirely on your own machine, so private documents are never uploaded. If your reading is mostly scanned pages, or coloured overlays and dyslexia fonts are essential to you, a dedicated assistive reading suite will cover those extras and Yaps will not.
What is read-along highlighting and why does it help?
Read-along highlighting marks each word on screen at the moment it is spoken, so the marker travels along the line with the voice. It helps because it holds your place for you: no finger under the line, no re-reading a line because your eye slipped, and an easy way back in after any interruption. In the Yaps reader, a reading, a note, or a Studio transcript is highlighted word by word, falling back to sentence by sentence where word level timings are not available.
Can you slow down text to speech for dyslexia?
Yes, and slowing it down is usually more useful than speeding it up. Yaps has presets at 0.75x, 1.0x, 1.25x, 1.5x and 2.0x, and 0.75x is the setting that keeps a dense paragraph from outrunning you. A good habit is changing speed as you go: fast through material you already know, slow through the sentences that carry the argument.
Is there a free text to speech app for dyslexia?
Yaps on Android is free and needs no account, so on a phone the answer is yes. Yaps on desktop, meaning Windows, macOS, and Linux, has no free tier: it opens into a 7-day free trial, which does require an account, and after that it is Pro at $15 a month or $12 a month billed annually. Your operating system also includes a basic reader at no cost, which is worth trying alongside it: Speak Selection on Apple devices, Read Aloud in Windows, and the equivalents on Android.
Does Yaps read aloud offline?
Yes. Read-aloud runs on your own device, so it works on a train, on a plane, in a building with no usable wifi, and in an office where uploading documents to a website is not allowed. Nothing you read is sent anywhere, which matters most for the documents that are hardest to read: contracts, letters from a solicitor, medical correspondence, and drafts you are not ready to show anybody.
Is Yaps a screen reader?
No, and the difference is important. A screen reader narrates the whole interface, telling you what every button and menu says so that a device can be operated without seeing it, and the mature free tools for that are VoiceOver on Apple devices, TalkBack on Android, and Narrator on Windows. Yaps reads text you select, which suits a reader who can see the screen perfectly well but finds decoding long text expensive. They work well side by side.
Can Yaps read a PDF aloud?
It can read a PDF that contains real text, which covers most PDFs produced by a computer. It cannot read a scanned or photographed page, because that is an image of words rather than words, and Yaps does not do OCR. If you have a folder of scans, make them searchable with an OCR tool first, then read them with Yaps. We walk through the longer workflow in the guide to turning a PDF into an audiobook.
What languages can Yaps read aloud?
On desktop, Yaps reads aloud in 31 languages entirely offline: English, Korean, Japanese, Arabic, Bulgarian, Czech, Danish, German, Greek, Spanish, Estonian, Finnish, French, Hindi, Croatian, Hungarian, Indonesian, Italian, Lithuanian, Latvian, Dutch, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Swedish, Turkish, Ukrainian, and Vietnamese. That is unusual, because private offline readers have tended to be English only and multilingual readers have tended to be cloud services. Mobile ships a smaller set of voices.
Can I save a document as an audio file to listen to later?
Yes, on desktop. A reading can be saved as a WAV audio file, which turns a long report, a chapter, or a set of course notes into something you can play on a phone, a speaker, or in the car with no app and no connection. Many readers use both directions: listen once on the way in, then read along with the highlight at the desk for the sections that matter.
Is Yaps suitable for dyslexic students at school or university?
It suits the everyday reading load well: set texts, papers, handouts with real text in them, and lecture material you want to hear once before working through it. Set the speed low, use their own reading rather than a sample, and let the student drive from the first attempt. Formal support is a different matter entirely, and assessment, exam access arrangements, and any specified assistive setup are for qualified professionals to determine, not for an app to promise.
Does Yaps have dyslexia-friendly fonts or coloured overlays?
No. Yaps does not restyle other applications, so it does not provide a dyslexia-specific typeface, wider letter spacing, or a tinted overlay over the text you are reading. If those are central to how you read, a dedicated assistive reading suite is the better fit for that specific need, and many combine them with OCR in one package. The Yaps Android keyboard has its own themes and fonts, but those apply to typing rather than to reading text elsewhere.
What about dictation, meaning getting my own words out?
That is the other half of the problem and Yaps handles it too, on-device and offline, with the filler words and false starts cleaned up automatically so a draft does not read like a transcript. It pairs neatly with read-aloud: dictate the draft, then have it read back to you in the reader with the highlight moving, which is the fastest way to hear a sentence that went wrong. We ranked the options in the best dictation software for dyslexia.
