Revenue for the quarter ending 31 March grew 18% year-over-year, driven primarily by expansion in the enterprise tier and a measurable reduction in SMB churn following the Q1 retention program. Operating margin compressed modestly as we continued to invest in the platform team, in line with guidance provided on the Q4 call.
Highlight follows each spoken word directly inside your Word window.

Three Steps — Same Gesture Every Time
Microsoft Word on Mac doesn't expose text through the standard Accessibility API — its document surface uses a custom layout engine. CastReader handles this the same way it handles Kindle and Apple Books: it sees what you see on screen, then maps each word precisely.
Install
Download CastReader for Mac (.dmg). Grant Accessibility permission and Screen Recording permission once. Screen Recording is required for Word because Word doesn't expose its document text through standard AX — we see the words the same way you do.
Select
Open your .docx in Word for Mac — report, resume, contract, paper. Drag-select the paragraph you want to hear. Works the same in Word 365, Word 2021, Word 2019, and Word 2016.
Click ▶
A play button appears next to your selection. One click — audio starts and the highlight glides inside the actual Word window, word by word. Works even when Word's ribbon and comment pane take up most of the screen.
When Professionals Add Read-Aloud to Word
Word is the default document editor for business and most of academia outside STEM. Contracts, reports, resumes, policy documents, legal briefs, journal submissions — if it has to look formal, it lives in a .docx.
Proof-listen your quarterly report
Board decks and investor reports get reviewed by fatigued eyes at 5pm. Listening once at 1.1× before you hit Send catches the sentence your CFO will quote back at you on the call.
Review resumes and cover letters aloud
A resume looks fine silently and then sounds wooden read aloud. Listening reveals the formulaic clauses and filler adjectives — exactly the spots recruiters mentally skip.
Study legal contracts and MSAs
30-page services agreements are where small clauses cost six figures. Listening at 0.9× gives you time to catch asymmetric indemnification, auto-renewal traps, and unusual termination windows.
Hear track-changes markup in your ear
Reviewing a long editor's comment pass on your thesis chapter or a co-author's revisions on a journal submission — selecting the full document and listening lets your eyes scan margins while the prose plays.
Read foreign-language .docx files
CastReader auto-detects language — Chinese contracts, Japanese business letters, German regulatory documents, Spanish legal filings. Kokoro-quality native voices; mixed-language docs switch at sentence boundaries.
Accessibility for dyslexia and long-session fatigue
Hours of .docx reading on screen destroys visual stamina regardless of baseline. A listening channel halves that — and for dyslexic professionals, it's the difference between finishing the contract review and shelving it.
Why CastReader Works on Word When Most TTS Tools Don't
Microsoft Word for Mac uses a custom layout renderer that doesn't expose text through macOS Accessibility the way Apple's own apps do. Most third-party TTS tools either don't support Word or fall back to clipboard-only reading with no highlight. CastReader handles it the same way it handles Kindle — OCR-as-source with pixel-accurate word bounding boxes.
Word-level highlight on the real Word window
Even though Word doesn't expose text through standard AX, CastReader reads what's on screen and maps each spoken word to pixel coordinates. The highlight overlay lands on the actual Word document, not a clone pane.
Works with locked corporate Word installs
If your IT department pushed a locked Microsoft 365 install and you can't add plug-ins, this still works. CastReader is a separate Mac app — it doesn't modify Word, doesn't add a toolbar, doesn't need admin approval.
40+ natural voices, CJK-aware
Chinese business reports, Japanese contracts, Spanish legal filings, Korean academic drafts — auto-detected with native Kokoro-quality voices. The same audio quality as the English path.
Zero cost, zero signup
No account, no credit card, no premium voice gate, no daily word limit, no per-seat enterprise license. Free forever — the TTS Word should have shipped with on Mac.
Common Questions
How do I read a Word document aloud on Mac?▾
Install CastReader for Mac (.dmg), grant Accessibility and Screen Recording permissions, open your .docx in Word, drag-select any paragraph, and click the floating ▶. Word-level highlight appears on your real Word window.
Doesn't Microsoft Word have Read Aloud built in?▾
Word has a Read Aloud feature, but on Mac it uses legacy macOS system voices that sound robotic by 2026 standards, provides only a flat underline (no word-level highlight), and can't be configured with modern natural voices. CastReader adds Kokoro-quality neural voices, word-level highlight on the real Word window, variable speed, and click-to-jump — at zero cost.
Why does Word need Screen Recording permission when Preview and Pages don't?▾
Microsoft Word for Mac uses a custom layout renderer that doesn't expose its document text through the macOS Accessibility API the way Apple's iWork apps do. CastReader handles Word the same way it handles Kindle and Apple Books — by seeing what's on screen and mapping each word to coordinates. Screen Recording is required for that path. Pages, Preview, TextEdit, and Notes are native AX apps and don't need it.
Does it work with Word 365, Word 2021, Word 2019, and Word 2016?▾
Yes — all modern Mac Word versions. The OCR-based path works with whatever Word renders, so version differences don't matter. Whether you have the Microsoft 365 subscription or a one-time purchase of Word for Mac 2021, it works the same.
Will it work with locked corporate / IT-managed Word installs?▾
Yes. CastReader is a separate Mac app — it doesn't modify Word, doesn't install a plug-in, doesn't need admin rights in Word itself. If your IT has locked the Microsoft 365 install, CastReader still works because it reads the screen, not Word's internals.
Can I listen to Chinese, Japanese, or Spanish .docx files?▾
Yes. CastReader auto-detects CJK and European languages and uses native Kokoro-quality voices. Chinese contracts, Japanese business letters, Spanish legal filings — all read natively. Mixed-language documents switch voice at sentence boundaries.
Does it work on track-changes markup?▾
Yes — CastReader reads whatever Word displays in the document body. If you have markup visible (Review tab → Display for Review → All Markup), selections will include the inline changes. Switch to No Markup if you want to hear only the accepted text.
Does it work on files in Word for Mac's OneDrive sync folder?▾
Yes. CastReader reads whatever Word renders on screen. Local files, OneDrive-synced files, SharePoint documents opened in Word — as long as the document is open in Word and text is visible, any selection reads aloud.
Is it really free?▾
Yes. 100% free — no account, no credit card, no per-seat license, no daily word limit, no enterprise activation. Download the .dmg and use it forever across every supported Mac app.
