Microsoft Edge Read Aloud vs Speechable

Built-in Edge neural TTS for web pages and PDFs, free with the browser, Immersive Reader extras, no separate app.

Web document-to-audio with unlimited free Eco Mode, podcast/lecture modes, and chat (not the unrelated App Store utility of the same name).
Audio
Voice quality

Online neural voices labeled (Natural) are the ones that matter, Microsoft's modern TTS, dozens of languages/accents (named voices like Alonso, Yunxia, etc.). Legacy non-Natural voices sound dramatically worse; skip them. Not ElevenLabs expressive range, but for free browser TTS it's genuinely listenable for long articles.

Eco Mode uses your browser’s local TTS (WebGPU-friendly browsers: Chrome 113+, Safari 17+, Firefox 141+). Unlimited and free; quality depends on your device voices. Cloud AI voices (~52 across several languages per their docs) sound better and burn credits. Day-to-day Eco Mode is usable; Premium voices are the “this could be a commute download” tier.
Voice selection

Long voice dropdown, regional accents (e.g. multiple French variants), speed control. Offline mode only keeps a few voices, plan on network for the good set.

Credit voices cover a real catalog (they advertise dozens of AI voices and multiple languages). Podcast and Lecture modes are separate formats, not just another voice picker: two-speaker discussion vs TED-style single explainer vs straight Listen narration.
Offline audio

Offline Read aloud exists but with a tiny voice set. No MP3 export library. You're listening inside Edge, not building an audiobook stash.

MP3 download for offline / phone listening is a first-class path, but it uses credits with a Premium-style voice. Eco Mode itself is in-browser; plan on export if you want AirPods on the train without the laptop.
Document processing
PDFs

Open a PDF in Edge's built-in viewer → same Read aloud shortcut/toolbar. Text-layer PDFs feed cleanly; this is where Edge beats Chrome's built-in story. Multi-column academic nightmares and image-only scans still fail like any dumb text-layer reader, no citation mute, no figure summaries. For "this PDF already has a text layer and I just want it spoken," it's excellent and free.

PDF upload with noise stripping aimed at papers: footnotes, inline citations, headers, reference-list sludge. Section picker so you can skip methods appendices on a first pass. Competing in the same “make papers listenable” lane as Paper2Audio / Listening. Speechable leans harder into podcast/lecture reformats than faithful full-text + figure summaries.
Web articles

Works on almost any page (Read aloud) vs article-shaped pages (Immersive Reader). Selection read-aloud for comments/sidebars you actually care about. No save-later archive, combine with collections/favourites or another read-later if you need a queue.

Paste a URL, strip ads, cookie walls UI, nav, sidebars, related-blocks, footer junk. Shows you the cleaned body before play. Strong use case vs Edge/Chrome read-aloud reading the chrome. Does not bypass paywalls: only what’s publicly visible.
OCR & scans


They claim OCR for scanned PDFs and photo uploads (notes, book pages). Useful if true on your scans; I’d still verify on a dense image PDF before betting a literature review on it.
Import workflow


URL paste, file upload (PDF / ebook-style docs per marketing), photo. No native mobile apps in this product: the desk browser is the app. Fine for laptop workflows; weaker if you only live on phone share sheets.
Layout fidelity


Clean-up is aggressive by design: you hear the argument, not every caption and citation. Great for comprehension; weaker if you need verbatim methods or figure-by-figure fidelity. For that job I’d still open Paper2Audio.
Listening workflow
Document chat

Not a listening library. No cross-device TTS position sync as a product feature, no playlists, no export. Copilot chat/summarise in Reading mode is the "study extra" where available, still browser-session thinking.

Chat (type or speak) against the imported doc (“what’s the main claim?”, vocab in another language, etc.). Credit-gated with the other AI features. Handy after a podcast skim when one claim didn’t stick.
Offline listening


Offline = generate + MP3, not a synced native player with a library on iOS/Android. Bring your own podcast app after download.
UI / UX
Web app

Ctrl+Shift+U (Windows) or Cmd+Shift+U (Mac) / right-click → Read aloud / ⋯ → More tools. Floating toolbar: play, voice options, speed. Words highlight as they speak; page dims slightly. Immersive Reader / Reading mode (F9 or book icon) strips ads/sidebars, adds line focus, syllable tools, picture dictionary, then Read aloud from there. Feels native because it is native.

Runs at app.speechable.co. Upload or paste a URL, review what was extracted, pick sections, then Eco Mode / Listen / Podcast / Lecture / Chat. Feels like a modern SaaS document desk, not a 2015 TTS toolbox. Sign-in with Google or email. Still early (I saw ~v0.7 on the login screen). Expect polish, not Voice Dream depth.
Library & organisation


Free plan is capped at 5 documents in their own marketing. Fine for trying the product; not a semester library. Premium is where the pile grows. Don’t treat it like Readwise Reader’s inbox.
Reading view

Immersive Reader / Reading mode is the polish layer, focus lines, fonts, backgrounds, Copilot summarise/explain in markets where Copilot is on. Reading mode is desktop-oriented; mobile Edge still has Read aloud without the full Reading mode suite (per Microsoft's notes).

You can inspect the extracted text and uncheck sections before audio. That review step matters for long guides and papers where you only want intro + discussion. Not a full Reader View with live word-sync on the original PDF layout the way Paper2Audio does. More “cleaned transcript first.”
Ease of use

Zero install beyond Edge. Select text → Read aloud selection for partial pages. PDF toolbar has its own Read aloud control when policy allows. Learning curve is "where is the menu," not another account + credit pack.

Paste URL → see cleaned article → play. Or drop a PDF and choose sections before you generate. Fewer knobs than Speechify’s suite; clearer “what am I listening to?” than dumping a messy page into browser Read aloud.
Platforms & ecosystem
Platform coverage

Edge on Windows, macOS, iOS, Android. Read aloud exists on mobile Edge too, but desktop is where it feels complete, Immersive Reader / Reading mode extras and background-listening polish are thinner on phones (Microsoft notes feature variance by device). Org policy can disable it (ReadAloudEnabled). You're locked into Edge as the browser, that's the whole trade.

Web only for speechable.co. Made-in-Tokyo marketing, Google/email auth. Eco Mode wants a modern browser with WebGPU. No official iOS/Android app for this product. Again, ignore the unrelated App Store listing with a similar name.
Pricing & limits
Free tier

Free with Edge. No TTS subscription, no character meter for Read aloud itself. Best $0 neural web/PDF listen if you'll use Microsoft's browser. Copilot-enhanced Reading mode extras may depend on account/market, core Read aloud doesn't require paying Speechify money.

Free tier is the hook: unlimited Eco Mode playback, 10 AI credits/month, library capped around 5 documents in their write-ups. No card required to start. Real free listening if you’ll accept browser voices.
Paid value

There is no Edge Read Aloud SKU. Value is "already paid $0." If you need libraries, offline audiobook files, citation-aware academic parsing, or non-Edge browsers, you still need another product, this is the free floor, not the full stack.

Premium $10/mo or $72/yr ($6/mo) with 1,200 credits/month. One-time $7 / 500 credits pack that doesn’t expire if you hate subscriptions. Trust-based accessibility discount up to ~50% (students, ADHD/dyslexia/vision, hardship; no proof required). Ethics page also leans hard on local Eco Mode energy use and “no training on your uploads.” Pricing is clearer and kinder than Speechify’s ~$139/yr vibe; credits still mean podcast/chat volume isn’t infinite on free.
