Listening & AI voices
ElevenReader vs Lectern
ElevenReader generates speech on ElevenLabs’ servers and offers very expressive voices, with offline listening only as pre-rendered downloads on its paid Ultra plan. Lectern runs Piper and Kokoro entirely on your phone, works with no connection once a voice is downloaded, and with those voices your book’s text never leaves the phone, for a one-time purchase.
Short answer: ElevenReader prepares speech using ElevenLabs’ cloud and offers offline playback of prepared downloads on eligible paid plans. Lectern generates new speech locally after you download a voice once. ElevenReader offers a wider voice selection and document inputs; Lectern favours private, unlimited on-device narration of your own ebooks.
Checked in September 2026 against Lectern 1.31 and the ElevenReader pages cited below.
What each one actually is
ElevenReader is ElevenLabs’ free document reader and audiobook app. You import a PDF, a DOCX, an EPUB, a Markdown or TXT file, paste text, drop in a web link, or scan a page with the camera, and it reads the result back in one of a broad selection of voices and languages. Speech is generated on ElevenLabs’ servers, and the app highlights each word as it’s spoken so you can follow along.
Lectern is a dedicated ebook and comic reader for Android. It opens books you already own, generates speech with the phone’s system voice or with Piper and Kokoro neural voices you download once, and highlights the sentence being read. There is no account, no ads, and no developer server: the app is a one-time purchase (about €2.49, varying by country) rather than a subscription.
Two different meanings of “offline”
ElevenLabs explains the current offline-download limits and expiry in its ElevenReader documentation.
Our roundup of offline text-to-speech apps draws a line between voices generated on the device and voices generated in the cloud but cached for later playback. ElevenReader and Lectern sit on opposite sides of that line, and it’s the whole difference between them.
ElevenReader’s offline downloads are the cached kind. You need a connection to prepare them, they’re available to eligible paid subscribers, they’re capped at 150 hours a month and 20 hours a day, and a finished download expires 60 days after you create it, so you have to reconnect and refresh it eventually. Free-plan offline downloads are not listed in the current documentation; check the current plan before subscribing.
Lectern’s narration is generated on the device itself. A Piper or Kokoro voice downloads once, with a download size that depends on the chosen model, and after that the app never needs the network to speak, doesn’t matter how many books or how many months pass. There’s no meter and nothing that expires.
What happens to your text
To read your document aloud, ElevenReader sends its text to ElevenLabs’ servers. Under ElevenLabs’ privacy policy, personal data is transferred to the United States for processing, and the company states it may use submitted content to “research, develop, train and/or otherwise improve” its AI models unless you opt out through the account privacy settings. That’s a standard cloud-AI arrangement, and reasonable for a news article; it’s a different question for a manuscript, a medical letter or a diary.
Lectern reads books from folders you choose on your own device and has no developer servers to send anything to. Per Lectern’s privacy policy, narration text never leaves the phone when you listen with Piper, Kokoro or an offline system voice; an online system voice depends on its provider. The app also uses the network for voice downloads and optional features such as OPDS and sync; local narration does not upload the book text for speech generation.
The honest trade-off on voice quality
This isn’t close to a wash, and it’s worth saying plainly: ElevenLabs’ hosted models can sound more expressive in many listening samples, with a wider range of character voices and emotional delivery than anything that fits in an app’s storage. On-device engines like Piper and Kokoro have closed a lot of that gap for steady, hours-long narration, which is what a novel actually needs, but they trade some of that expressiveness for running locally, at no per-hour cost, with no connection required. Neither app wins outright; they’re optimising for different things. We compare the two engines themselves in Piper vs Kokoro.

Who should choose which
Occasional articles, PDFs or study notes
ElevenReader. The free tier is generous for shorter documents, the voices are excellent, and being online while you read a report is a small ask.
A private manuscript, contract or medical letter
Lectern. Local narration does not send the text to a TTS server; confirm the file format and your optional sync settings before importing sensitive material.
A whole ebook library, read over weeks
Lectern. No monthly hour cap, no expiring downloads, no meter running while you commute.
DOCX files, web articles, or the widest voice and language choice
ElevenReader. Lectern is an ebook and comic reader; it doesn’t open Word documents or pull in web pages.
Nothing stops you running both: ElevenReader for the odd PDF, Lectern for the books that live in your library.
Frequently asked
Does ElevenReader ever work with no internet connection at all?
Not for generating new speech, and only partly for playback. Offline downloads are pre-rendered audio you prepare while online, available on eligible paid plans, capped at 150 hours a month and 20 hours a day, and they expire 60 days after you create them.
Is Lectern’s on-device narration as expressive as ElevenReader’s?
Not quite. ElevenLabs’ hosted models may sound more expressive, depending on the voice and text. Piper and especially Kokoro are comfortable for hours of steady narration, which closes most of the practical gap for reading a book, without the connection, account or per-hour cost.
What does ElevenReader do with the text you import?
It sends the text to ElevenLabs’ servers to generate speech. Under ElevenLabs’ privacy policy that data is processed in the United States, and may be subject to data-use settings; check the current privacy policy and your account settings before importing sensitive material.
Can either app read comics or scanned pages?
Lectern opens CBZ, CBR, CB7 and CBT comic archives directly and can reflow PDFs into readable text. ElevenReader isn’t built for comics, but it can OCR a camera-scanned page into readable, speakable text, which Lectern doesn’t do.
