Has anyone mentioned Voice yet? Because Voice is the answer. The speed slider goes from 0.5x to 3.0x, and it's buttery smooth. What I love is that you can set a one-tap button to your favorite speed—mine's 1.7x for most narrators.
It also supports OPDS for getting books from online catalogs, which is a nice bonus if you use certain... unofficial libraries. The developer is active, and the app just keeps getting better.

I get excited talking about this because it's one of those small features that changes how I devour stories. Yes — a free audiobook app absolutely can support variable playback speeds, and many already do. Technically, there are two basic ways apps implement it: naive resampling, which simply plays the audio faster and raises pitch (think squeaky chipmunks), and time-stretching algorithms that preserve pitch while changing tempo. The latter uses techniques like WSOLA or phase vocoding under the hood, and modern mobile CPUs handle that just fine for single-stream audiobook playback.
From a practical perspective, supporting speed control also means building a decent UI (speed presets, a scrub-friendly slider, and a short-term boost button), handling bookmarks and chapter sync correctly when tempo changes, and preserving metadata so sleep timers and position syncing across devices still work. Free apps can lean on open-source audio libraries and platform audio frameworks — for example, ExoPlayer on Android or AVAudioEngine on iOS — to implement smooth, pitch-corrected speed changes without reinventing the wheel. Even with limited development budgets, prioritizing UX around speed (easy access, clear labels like 1.25x, 1.5x, 2x) makes the feature feel premium.
I love that variable speed isn't reserved for paid apps; it makes rereads and long commutes so much better, and when it's implemented thoughtfully it feels like the app actually understands how I listen.

Don't overlook 'Libby' by OverDrive if you get audiobooks from your library! It's not a general file player, but for library loans, it has both a sleep timer and variable speed control built right in. The timer can be set in minute increments or by chapter end. Speed goes in increments from 0.6x to 3x. The best part is it's completely free with no ads, since it's tied to your library card. Obviously, it only plays books you borrow, but for that purpose, it's fantastic and often forgotten in these conversations.

I think the emotional impact of speed control is under-discussed. Slowing down a poignant scene can make it more powerful. Speeding up a tense chase can increase the adrenaline. The best apps give you that directorial control over your emotional experience. It's not just about efficiency; it's about engagement. An app that facilitates that connection between the story and your internal rhythm is doing something special. It turns passive listening into an interactive, personalized journey. That's more than a feature; it's a form of creative participation.

Google Play Books handles audiobooks now, and yep, you can change the narration speed. I like it because it syncs across devices seamlessly. Start on my Android phone, pick up on my tablet. The selection isn't as vast as Audible, but if you buy an audiobook there, the app experience is solid and includes all the basic controls you'd expect.

Wait, does the Kindle app count? It has a text-to-speech feature called 'Immersion Reading' for some books. It's not a human-narrated audiobook, but a robotic voice that reads the ebook aloud. And you can adjust the speed of that voice in the settings.
If you own the Kindle ebook (and many classics are free or very cheap), this feature is available. It's not a pleasant as a professional narration, but for the price of a free ebook, you get an audible version with adjustable speed. It's a last-ditch option, but an option nonetheless.

I bounced between apps for months. Voice, Smart, Listen... they all have merits. But for Bluetooth, the consistency winner for me turned out to be 'Just Another Audiobook Player.' Yeah, that's its real name. It's on F-Droid and GitHub. It's super lightweight, and because it's simple, there's less to go wrong with the Bluetooth stack.
I had weird delays with other players where I'd press 'next' and it would take a second. This one is instantaneous. It's not as polished visually, and the library browsing is basic, but if the primary interface for your listening is your Bluetooth controls, not the phone screen, then this app's simplicity becomes its greatest strength. Highly recommend for the tech-savvy who want control.

I love geeking out about this stuff — audio speed control is one of those small features that makes reading on devices feel like a personal superpower. If you want e-books with adjustable narration, start with the big players: Audible (the Audible app) definitely lets you change playback speed, and when you pair an Audible audiobook with the Kindle app using "Immersion Reading," you get synced text-and-voice playback while controlling the Audible speed. Google Play Books also supports audiobooks and has simple speed controls in the player, and Apple Books gives you the same for purchased audiobooks and lets the iOS Speak Screen or "Speech" settings read ePub/PDF text at a chosen rate.
For library users, Libby (by OverDrive) is fantastic — it streams library audiobooks and includes speed controls, which is huge when you don’t want to sit at 1x. If you prefer synthesized TTS for your own ePubs/PDFs, apps like Voice Dream Reader, Speechify, and NaturalReader offer fine-grained speed sliders and high-quality voices. On Android, Moon+ Reader and FBReader let you hook into the system TTS engine and tweak rate; on Windows, tools like Balabolka or desktop NaturalReader do the same. My tip: try a few speeds and voices — 1.25x–1.5x often feels natural, but some voices remain clearer even at 1.75x.
Finally, remember platform quirks: some e-readers (hardware) rely on app-level features or the device's OS speech settings, so when in doubt check the app settings or the device accessibility speech rate. I’ve bounced between Audible, Libby, and Voice Dream depending on whether I’m buying, borrowing, or importing files — each has its own sweet spot.

Hmm, I should really look into this. I've been using the default music app for my audiobook files and just dealing with the fixed speed. Seeing all these options with speed control makes me think I've been making life harder for myself. Gonna try that Voice app everyone's mentioning later.
