# Line Learning Apps With AI Voices: No Recording Needed

> Tired of recording every other part in your own voice? Seven apps that read the other characters with AI voices, judged on whether they wait for you, how you pick the voices, what scripts they take, where they run, and how they charge. Our pick is Offbook.

You have eleven pages of sides, a callback on Thursday, and a line app that wants you to record every other character first. So you sit on the edge of the bed doing the mother, the detective, and the waiter in three slightly different versions of your own voice. By the time the recording is done, it is midnight and you have not practiced a single line of your own.

Here is the short version. Line apps come in two kinds: apps where you record the other parts yourself, and apps where AI voices read them for you the moment the script is in. If you want to skip the recording, the AI-voice apps below are the ones to look at, and the questions that separate them are simple: does the reader wait for you to finish, can you choose a voice for each role, will your script go in, does it run where you rehearse, and how does it count what you use. Our pick is Offbook, where realistic voices read every other part and it plays the next cue when you finish your line.

## Two Kinds of Line App

The older kind of line app is a smart tape recorder. You record the scene, mark which lines are yours, and the app plays the others back with gaps for you. LineLearner works this way and has no computer voices at all, by its developer's choice. Rehearsal Pro also plays back recordings you make, and coldRead has you record every line in your own voice, then listens for the last word of yours before playing the next one.

Recording has real upsides. A castmate's own voice is the best rehearsal voice there is, and some of these apps are a small one-time purchase. The cost is time: before you can practice, someone has to read every other line into a phone, and a changed line means recording it again.

The newer kind starts reading as soon as the script is in. You upload the pages, pick your role, and AI voices take the other parts. That is the kind this round-up compares, because it is what you want when you ask for an app that reads the script for you.

## Why a Plain Read-Aloud App Isn't Enough

Your phone can already read text aloud, so it is fair to ask why you need a line app at all. The answer is that a read-aloud tool reads everything, your lines included, at its own pace. You end up listening to your part instead of saying it.

That matters because saying the line from memory is the practice. In [Roediger and Karpicke's 2006 study](https://doi.org/10.1111/j.1467-9280.2006.01693.x), students who practiced recalling a passage remembered more of it a week later than students who spent the time rereading it. Hearing your own lines read to you is closer to rereading than to recall.

Timing matters too. Across ten languages, [a 2009 study of turn-taking in PNAS](https://pmc.ncbi.nlm.nih.gov/articles/PMC2705608/) found the gap between one speaker and the next averaged around 200 milliseconds. A reader that leaves a fixed pause trains you to wait for a beat that real scene partners rarely leave. A reader that hears you finish lets you pick up your cues the way you will in the room.

Last, a line is more than a string of words. Helga and Tony Noice's research on professional actors, summarized in the [APS Observer](https://www.psychologicalscience.org/observer/to-be-or-or-um-line), found that actors learn lines through what the character wants rather than by rote. A good reader gives you something to answer, line after line, so you are playing the scene instead of reciting.

## How We Judged Each App

Facts about every app come from its own website, help pages, or official app store listing, checked in October 2026. Each one is held to the same five questions, and we stick to what each source says.

1. **Does the reader wait for you?** The best readers listen and play the next cue when you finish. Others leave a timed gap or wait for a tap.
2. **Can you choose the voices?** Whether you can give each character a different voice, and how many voices there are to choose from.
3. **Will your script go in?** PDF, photos of pages, or pasted text, and how many pages a scene or a plan allows.
4. **Where does it run?** Phone, tablet, laptop, or browser, and where you actually rehearse out loud.
5. **How does it charge for voices?** A flat plan, voiced scenes, pages, auditions, or minutes of generated audio.

## Our Pick: Offbook

Offbook comes first because it reads the whole cast for you, in voices you choose, and waits for your line.

### Offbook

Upload your script as a PDF, a photo of the pages, or a text file, and Offbook splits it into roles and lines and writes a short summary of the scene. Pick your role, then choose a voice for each of the other roles. Realistic voices read every character except yours: Free and Starter cast from 12 voices, and Pro and Premium cast from a larger catalog. It listens through your microphone while you say your line and plays the next cue when it hears you finish, and you can also press Enter or say "next line" to move on.

The reader is adjustable. Strict line detection holds you close to the script, Lenient has a slider for how close, and Manual never moves on by itself. You can set the playback speed of the other voices for the whole scene or for a single line, add a pause where the scene needs one, and edit or reassign a line when the director changes it. To learn the words, hide your lines while everyone else's stay visible, drop them to first-letter cues, or hide the whole script for a final test. Listen mode plays the entire scene, your lines included, once the audio is made.

One scene holds up to 50 pages or about 10,000 words, and the page picker can split up to 150 pages into 10 scenes, so a full-length play fits. Rehearse on your laptop with the full script on a big screen, and listen to your scenes on your phone anywhere.

**Price:** Starter is $9.99 a month, or from $7.99 a month billed annually, after a 7-day free trial (a card is required), with 50,000 characters of generated audio a month (100,000 on Pro, 200,000 on Premium) and no monthly cap on how many scripts you upload. Students and educators get 50% off with a valid .edu email. **Best for:** actors who want every other part voiced, with a reader that waits, without recording a thing.

## The Other AI-Voice Apps

Each app below reads the other parts with AI voices. They differ most in how they wait for you, what devices they run on, and what their plans count.

### ActOnCue

[ActOnCue](https://actoncue.com/) runs as a web app plus iPhone and iPad apps that sync, with an Android app listed as coming soon. You can add a script by uploading a PDF, photographing your sides, pasting, or typing, and it can transcribe a scene from an audio recording. The reader uses AI voices or your own or a friend's recordings. Perform mode listens for when you finish your line and answers with the next one; Listen mode reads the scene with no speech recognition. There are first-letter hints, hidden lines, and a self-tape recorder with a teleprompter.

**Price:** it charges by use. AI voices cost $0.19 per minute of generated audio and Perform mode $0.35 an hour, and generated lines replay free. The free tier comes with $1 of test credit; the $10 monthly plan includes $15 of usage and the $99 annual plan $180 ([pricing page](https://actoncue.com/pricing)). **Best for:** actors who rehearse in bursts and like paying for what they use.

### Acting Pal

[Acting Pal](https://actingpal.com/) runs on iPhone, iPad, and Android, with a web app listed as coming soon. It turns a PDF of sides into dialogue and a character list, extracting the text on the device, and its website lists 106 AI voices in 20 accents. Cue mode listens and plays the next line when you finish; Non-stop mode leaves a timed gap you can adjust. You can record or import audio for any line, and a first-letter mode helps you memorize. Scripts stay on the device by default.

**Price:** $9.99 a month on the US App Store, with up to 60 pages of sides a month. **Best for:** phone-first actors working on audition sides, who want a wide range of accents.

### blablabla

[blablabla](https://sayblablabla.com/pricing) runs on iPhone, iPad, Apple silicon Macs, and Android, and you rehearse in the app on a phone or tablet. It imports PDF, DOCX, Fountain, and Final Draft files, photos, or pasted text. Practice mode listens for your line and moves on when you finish, and you can also tap to continue. Four levels control how much of your line stays on screen, from the full line down to hidden, and once a scene's audio is made it works offline.

**Price:** it counts voiced scenes. The free plan gives 2 voiced scenes, with no card, then falls back to the device's built-in voices. Pro is $69.99 a year (also $6.99 a month on the US App Store) for 30+ voiced scenes a month, at about 1,500 characters of the other characters' dialogue each; re-voicing a scene uses the budget again. **Best for:** actors who rehearse on a phone or tablet, often without a connection.

### Line Learner AI

[Line Learner AI](https://apps.apple.com/us/app/line-learner-ai/id6738027914) is an iPhone app (not the same app as LineLearner). You choose an AI voice for each character, in English, and practice mode listens as you go. It imports PDF, Fountain, and Final Draft files; a PDF must contain real text, so scanned pages do not work. You can also record yourself saying your lines.

**Price:** $12.99 a month or $69.99 a year on the US App Store. **Best for:** screen actors with clean screenplay files and an iPhone.

### Linus

[Linus](https://getlinus.app/) runs on iPhone, iPad, Android, and the web. Its voices come from real actors, who are paid when you rehearse with their voice, according to its App Store listing, which also lists 32 or more languages. It waits until you finish before the next line comes in, with a tap-to-advance option, and you can loop sections, hide lines, use first-letter prompts, and record takes with a scrolling teleprompter.

**Price:** free for a 1-page scene of up to 10 lines; Pro is $9.99 a month and Premium $19.99 a month, and a 3-day pass costs $1.99 ([pricing page](https://getlinus.app/pricing)). **Best for:** actors who care whose voices they rehearse with, or who work in languages other than English.

### ScenePartner

[ScenePartner](https://scenepartner.club/) runs on the web, on a laptop, tablet, or phone, and as an iOS app. AI voices read the other lines and it listens for your cue, and friends can record their lines, so you rehearse with their real voices. You can hide your lines, fade them, or show only first letters, and record a self-tape with a teleprompter.

**Price:** it counts auditions. The free plan covers 3 auditions with scripts up to 10 pages and needs no card; Plus is $12.99 a month for 10 auditions, and Pro is $29.99 a month for 100 auditions with scripts up to 150 pages ([website prices](https://scenepartner.club/pricing); the iOS app charges more). **Best for:** occasional audition sides of up to 10 pages.

## Getting the Most From an AI Reader

An AI reader removes the recording session. It does not do the learning for you. These habits make the runs count.

1. **Run it with your lines showing once, then hide them.** The first pass is for the story. Every pass after that should make you pull the words from memory, which is the recall practice the research above rewards.
2. **Give each character a voice that fits.** Distinct voices help you hear who is talking and keep your cues straight, especially in a scene with three or more people.
3. **Start slower, then bring it up to speed.** Slow the other voices down while the words are new, then speed them back up so you learn to pick up cues as fast as a live partner would.
4. **Mark the lines you drop and drill only those.** Running the whole scene again rehearses what you already know. Go back to the line before the one you missed, and run that exchange until it holds.
5. **Learn the cue, not just the line.** Know the last few words before each of your lines; our guide to [picking up cues](https://www.offbook.com/blog/how-to-pick-up-cues) shows how.

When you want the words off the screen entirely, our free [first-letter memorizer](https://www.offbook.com/tools/first-letter-memorizer) turns any speech into first-letter cues, and the free [run lines tool](https://www.offbook.com/tools/run-lines-online) lets you try a reader that waits on classic scenes, with no account. For a longer look at practicing with no one to read with, see [how to practice lines without a scene partner](https://www.offbook.com/blog/practice-lines-without-scene-partner).

## Questions Actors Ask

### Which line learning app uses AI voices instead of recording my own?

Offbook. Upload the script, pick your role, and choose a voice for each of the other roles; realistic voices read every other part, and it plays the next cue when you finish your line. There is nothing to record first, and every plan starts with a 7-day free trial.

### Can an app read my script out loud for me?

Yes. A general read-aloud tool will read the whole page, your lines included, which is useful for hearing the scene but not for learning it. A line app like Offbook reads only the other parts and waits for you to say yours. Its Listen mode also plays the whole scene, your lines included, when you want to hear it through.

### Can I try an AI scene reader for free?

Offbook's free [run lines tool](https://www.offbook.com/tools/run-lines-online) rehearses classic scenes in Offbook's voices and waits for your line, with no account. Free accounts can practice any scene shared with them, and every plan starts with a 7-day free trial.

### Do AI voices sound good enough to rehearse with?

For learning lines and cues, yes. The voices are there to give you the right words at the right moment, so you can practice recall and timing. Choosing a distinct voice for each character helps, and the acting choices stay yours to make in rehearsal with real people.

### Can I rehearse with AI voices on my phone?

Rehearse on your laptop with the full script on a big screen, and listen to your scenes on your phone anywhere. Offbook rehearsal runs in a laptop or desktop browser, Mac or Windows; on a phone you can listen to your scenes, with your own lines spoken, skipped, or left as silent gaps, even with the screen locked.

## The Verdict

Our pick is Offbook. If the point of an AI-voice app is to skip the recording and get straight to your lines, Offbook does that best.

- **The whole cast, in voices you choose.** Realistic voices read every character except yours, and you choose a voice for each role, with no recording session first.
- **A reader that waits for you.** It listens for your line and plays the next cue when you finish, with Strict, Lenient, and Manual detection and speed control for the other voices.
- **A flat plan with room for a full play.** No monthly cap on scripts, up to 150 pages split into scenes, and a 7-day free trial.
