Offline text to speech on your Mac, no cloud required

Yes, and it's better than most people realize. Under System Settings → Accessibility → Read & Speak (labelled Spoken Content on earlier versions of macOS), enable Speak selection. From then on, select any text in any app and press Option + Esc, and your Mac reads it aloud. An on-screen controller can appear with pause and speaking-rate controls, you can choose among the system voices (and download more), and words or sentences can highlight as they're spoken. There's even a say command in Terminal if you like your text-to-speech scriptable.

All of it runs on your Mac, no cloud and no account. For a paragraph, an email, or a quick proofread by ear, the built-in feature is exactly the right tool.

At length. Spoken Content speaks the text you select, and that's all it does: there's no library, no reading position, and no sense of a document. Listening to a 300-page book means selecting text over and over and remembering where you stopped yourself. The system voices are also built for utility, clear but noticeably synthetic over a multi-hour listen.

That's the gap a dedicated reader fills. It treats text to speech as a way to actually read books and documents by ear, rather than as an accessibility shortcut.

LoudReader turns any EPUB, PDF, or article into an audiobook with natural offline voices. It runs on iPhone, iPad, and Apple Silicon Macs, not a web wrapper, and every word of speech is generated on your device by a modern neural TTS engine. Books are not uploaded for narration. There's no account and no sign-up.

Import a book and press play: the voice reads while each word highlights in the text, your place is saved automatically, and a built-in catalog offers 70,000+ free Project Gutenberg classics. The free tier includes unlimited listening on every book, cover to cover, with no word quota, and the FAQ has the full free-vs-Premium breakdown.

They're not really rivals. Spoken Content is the right tool for a selected paragraph, and LoudReader is the right tool when the thing you want to hear is a book, a long PDF, or your article backlog. Many people use both.

Three reasons, in increasing order of importance:

• It works everywhere. Planes, trains, tethered laptops, flaky hotel Wi-Fi: narration generated on your own machine does not depend on a live speech server. Device speed and resource availability can still affect playback.
• No quotas. Cloud TTS services meter usage because synthesis costs them server time. When the engine runs on your Mac, there's nothing to meter, and LoudReader has no book-listening word limits on any tier.
• Privacy. Local synthesis avoids sending your text to a speech provider. Other app data flows need separate consideration. See private text to speech with no cloud for the full argument, and the privacy policy for its diagnostics and analytics disclosures.

An Apple Silicon Mac (M1 or newer) running macOS 15 or later. The neural voices lean on Apple Silicon's machine-learning hardware. To be straight about it: if you have an Intel Mac, LoudReader won't run, and the built-in Spoken Content feature is your offline option. On iPhone and iPad, LoudReader needs iOS or iPadOS 18+.
