How to read aloud on a Chromebook

Two built-in ways (Select-to-speak and Chrome’s Read aloud), what each one won’t read, and how a free extension handles long PDFs and Docs.

Every Chromebook can read aloud without installing anything: turn on Select-to-speak in Accessibility settings, then hold the Search key and drag over any text. For a whole article, Chrome’s Reading mode has a Play button.

If you’re working out how to read aloud on a Chromebook, you’re probably a student with a school device, a parent setting one up, or a teacher who needs an accommodation working by Monday. The tools are built in, a few menus deep, and each reads some things and not others. Steps were checked against Google’s help pages in October 2026. The reason to bother: a meta-analysis of 22 studies found that text-to-speech and other read-aloud tools improved reading comprehension for students with reading disabilities by an average effect of d = 0.35 (0.24 after correcting for publication bias). Those studies rarely tested speech speed or word highlighting, so treat those as settings to try, not proven ingredients.

What a Chromebook does on its own

Three ways. Select-to-speak reads only what you point at and highlights each word; it works on web pages, Google Docs, Slides and Forms, and most PDFs opened in Chrome. Read aloud in Reading mode reads a whole article from Chrome’s side panel. ChromeVox is a full screen reader for blind and low-vision users; it speaks everything, menus included. For schoolwork, start with Select-to-speak.

Turn on Select-to-speak

  1. At the bottom right, click the time (or press Alt + Shift + S), open Settings, then Accessibility.
  2. Under Text-to-Speech, turn on Select-to-speak. A speaker icon appears near the clock.
    Settings › Accessibility › Text-to-Speech
    Text-to-Speech
    ChromeVox (spoken feedback)
    Select-to-speak
    Leave ChromeVox off unless you want every button and notification spoken too.
  3. Hold the Search key (where Caps Lock would be) and drag a box over the text; let go and it reads. Or highlight text first and press Search + S. On a touchscreen, tap the speaker icon, then tap a line.
  4. To stop, press Ctrl or the Search key. Open select-to-speak settings lets you change the highlight colour or shade everything but the sentence being read.

Read a whole page with Read aloud

  1. In Chrome, open the article, click the three-dot More menu, then More tools, then Reading mode.
  2. Press Play (or K). The toolbar has Playback speed, Voice and Turn on highlight; Previous and Next jump by sentence.
  3. Click Pin to toolbar so it is one click next time.

Google’s page says Read aloud is only on Chromebooks and describes it on “general websites”; it does not list PDFs or Google Docs. For those, use Select-to-speak or an extension.

Do it in Hearald

Select-to-speak suits a paragraph at a time. The gap shows with a 30-page PDF or a shared Doc, where dragging a box over every screen gets old and nothing marks where you stopped. Hearald is a free Chrome extension, so it installs on a Chromebook like on any Chrome and reads the whole document from a player.

  1. Install Hearald from the Chrome Web Store and pin it.
  2. Open the web page, PDF or Google Doc. For a Doc, Hearald fetches its plain-text copy with your own signed-in session and opens it in its own reading view (view-only Docs work unless the owner turned off downloading).
  3. Press play. The voice runs on the Chromebook itself, nothing is sent to a server, the reading keeps going offline, and each word is highlighted as it is read.

    Light striking the thylakoid membrane excites electrons in chlorophyll, and the energy released drives the proton pump. The gradient that builds is what makes ATP.

    The player marks each section and lights up the word being spoken, so your eyes stay on the line instead of drifting.
  4. Use the section list to skip ahead or jump back.
  5. After a section, write what you remember in a note; the check lists the section’s key points and shows which ones your note missed. The first three notes are free.
  1. 1. Open the documentWeb page, PDF or Doc
  2. 2. Hearald pulls the textAnd splits it into sections
  3. 3. Listen and followDevice voice, offline, words lit
  4. 4. Write a noteWhat you remember, in your words
  5. 5. The check shows the gapsKey points your note missed
Step 5 is the one that tells you whether the listening actually worked.

Where people get it wrong

The common mistake is turning on ChromeVox when the goal was Select-to-speak: every tab and notification gets announced, the student is overwhelmed, and read-aloud is written off. Press Ctrl + Alt + Z to toggle ChromeVox off and turn on Select-to-speak instead. The second mistake is treating read-aloud as the whole job: the meta-analysis above measured comprehension right after reading, not what stuck a week later. Pause after each section and say back what it covered before you start the next one.

Recall check

Three questions. Answer them out loud before you open the answers.

  1. Which built-in ChromeOS tool reads only the text you point at, and which one reads everything on screen?
  2. You have highlighted a paragraph with the trackpad. Which keys make the Chromebook read it?
  3. A student opens a 40-page PDF in Chrome and looks for Play in Reading mode. What should they expect, and what should they use instead?
Show answers
  1. Select-to-speak reads what you point at; ChromeVox is the full screen reader that speaks everything, including menus.
  2. Search + S. Or hold the Search key and drag a box over the text instead of highlighting first.
  3. Google describes Reading mode for web articles and doesn’t list PDFs, so don’t count on it. Use Select-to-speak a screen at a time, or an extension that reads the whole PDF from a player.

If the Chromebook’s reading is mostly long PDFs and shared Docs, give Hearald a shot and put it in your browser.
