Speech Central vs Speechable
Audio
Voice quality

Default = high-quality device/system voices (Apple voices on iOS/Mac, Android TTS engines on Play). Offline and private. Optional cloud AI via your API keys, OpenAI-compatible (incl. self-hosted), Microsoft Azure, Google Cloud, xAI, plus a proprietary enhancement/streaming layer. Quality ceiling depends on what you wire up; stock offline is good-not-ElevenLabs.

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

Open voice platform is the differentiator vs locked catalogs. Bring keys, pick engines, enhance playback. Pronunciation customisation exists (see their help docs). Not a 1,000-voice marketing wall, it's "bring your own neural budget."

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 device voices are first-class. Audio export supported where offline voices allow. Sleep Assistant (evolved from sleep timer + night mode) for bedtime listening. No mandatory cloud account for core reading.

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

Marketed as optimised PDF reading order + navigation, optional cleanup for headers/footnotes/citations/links, scanned PDFs including two-column layouts. Help docs are honest that some PDFs/web pages lack extractable structure, copy-paste fallback exists. One of the stronger "serious PDF listener" stories among one-time-purchase apps.

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.
Ebooks

EPUB, Word, PowerPoint, OpenOffice, HTML/TXT/RTF/Markdown. DRM-protected Kindle-type books are incompatible (stated clearly). Broad document net for a one-time app.

Web articles

Full articles, headlines, RSS, share-to-read-aloud from browsers/other apps. Instapaper integration + optional auto-archive on Android. Web all-in-one is a core pitch alongside PDF.

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

Annotate while reading, export annotated text to.docx, optional AI summarization tools. Study/knowledge angle without becoming Readwise.

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

Privacy-by-design offline listening is the lifestyle, no tracking, no usage analytics per their claims. Sync on Apple via iCloud across phone/pad/Mac/Watch.

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

Full iPhone/iPad app with CarPlay, independent Apple Watch listening, Health mindful-minutes optional, iCloud position/playlist sync across Apple devices. Share sheet from Safari is the daily path. Free has a daily article/book cap; Pro unlocks unlimited. Dense settings if you dig, Instant Mode exists for tap-and-listen.

Android app

Play Store presence is strong, offline voices, speed/pitch, customisable "Read Fast," Chromebook layouts. TalkBack users get Pro unlocked free. Same one-time philosophy as iOS. UI is powerful rather than Instagram-pretty; reviews call depth a feature once you learn it.

Web app


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


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

Instant Mode is easy. Full settings (voices, cleanup, profiles, API keys) are deeper than Speechify-casual. Accessibility profiles change behaviour, not just a font toggle, worth the learning curve if ADHD/dyslexia/low vision is why you're here.

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.
Desktop App

Native Mac (Intel + Apple Silicon) and Windows apps from their stores. Same "serious reading" feature set without living in a browser tab. Separate purchase from mobile, plan for that if you hop platforms.

Platforms & ecosystem
Platform coverage

iOS, Android (phone/tablet), Mac, Windows, wider native footprint than most TTS apps. Free for VoiceOver/TalkBack users and MDM/school-managed deployments (they claim 100k+ school installs).

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.
Sync

Apple ecosystem sync is solid. Cross-OS sync is not a unified cloud account story, licenses are per store/platform, so Android↔iOS isn't "one purchase everywhere."

Pricing & limits
Free tier

Free with daily/monthly article or book limits (exact caps vary by store listing). Enough to evaluate the app; Pro is the daily-driver unlock. Blind users (VoiceOver/TalkBack) and managed school devices get Pro free.

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

One-time Pro, roughly $9.99 iOS (US App Store), similar single-digit prices on Android / Mac / Windows Store (confirm live; Windows has been listed around ~$8). No subscription. Separate license per platform family, iOS ≠ Mac ≠ Android ≠ Windows. Vs Voice Dream's yearly SKUs or Speechify monthly, long-term math is excellent if you stay on one OS. Cloud neural voices still cost whatever your API provider bills. Free daily import caps apply until Pro; VoiceOver/TalkBack and MDM school devices get Pro free.

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.
Accessibility
Extra section
Dyslexia Adhd

Dedicated ADHD, dyslexia, and low-vision profiles that change layout and behaviour, not just a font swap. Automatic adjustments when TalkBack is on. Feels built for print-disability and focus use cases in a way casual TTS apps often aren't, at least in my testing.
