Upload a PDF, a photo of the pages (PNG or JPEG), or a text file, and it sorts the pages into roles and lines. Pick your role, and realistic voices read every other character. Free and Starter cast from 12 voices; Pro and Premium cast from a larger catalog. When you rehearse, it plays the other lines, listens through your microphone while you say yours, and plays the next cue when it detects you've finished. For memorizing, hide your own lines while everyone else's stay visible, hide the whole script for a final test, or swap your lines for the first 1-8 letters of each word. The teleprompter shows your line large and highlights each word as you say it, scene looping restarts the scene when it ends, and listen mode plays the whole scene aloud. 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, Pro $14.99, and Premium $29.99, with annual billing from $7.99 a month. Every plan starts with a 7-day free trial (card required), and paid plans have no monthly cap on the number of scripts. Generated audio is 50,000 characters a month on Starter, 100,000 on Pro, and 200,000 on Premium. **Best for:** actors who want a reader that hears them finish, for anything from two pages of sides to a full-length play. ### blablabla [blablabla](https://sayblablabla.com/features), from Vox Vera ApS, reads the other parts with AI voices. Its website and US App Store listing say Practice mode listens for your line and moves on when you finish, and you can also tap to continue. Practice mode has four levels of how much of your line stays on screen: the full line, a hint, first letters, or nothing. It tracks your accuracy line by line, and its FAQ says the app never coaches you. Its [pricing page](https://sayblablabla.com/pricing) lists imports from PDF, DOCX, Fountain, Final Draft, photos, and pasted text. Once the audio is generated, it works offline. You rehearse in the app on a phone or tablet (iPhone, iPad, or Android); on a computer, its free practice scenes can only be read in a browser. For self-tapes it has a landscape teleprompter, the front or back camera, and a mic check, and takes stay on your device. **Price:** 2 voiced scenes free for life, with no card; after that, the app uses your device's built-in voices. Pro is $69.99 a year (the [US App Store](https://apps.apple.com/us/app/id6760597750) also lists $6.99 a month) for 30+ voiced scenes a month, and one voiced scene is about 1,500 characters of the other characters' dialogue. Re-voicing a scene uses the budget again. One-off packs are $1.49 for 3 scenes and $4.99 for 10. **Best for:** actors who want a phone app with a set monthly scene budget. ### Line Learner AI [Line Learner AI](https://apps.apple.com/us/app/line-learner-ai/id6738027914), by Marko Dragas, gives each character its own AI voice, in English, and its practice mode listens as you go. A release note added recording yourself saying your lines. It imports PDF, Fountain, and Final Draft files; scanned PDFs aren't supported, so the PDF has to contain real text. Its [UK App Store listing](https://apps.apple.com/gb/app/line-learner-ai/id6738027914) marks it "Designed for iPhone" and "Not verified for macOS". It is an iPhone app. **Price:** $12.99 a month or $69.99 a year in the US App Store. **Best for:** iPhone users whose sides come as a text-based (not scanned) PDF, Fountain, or Final Draft file. ## Who Reads the Other Parts All three apps give the other characters computer voices, so none needs a recording session first. blablabla voices scenes from a budget: 2 free scenes, after which the free app uses your device's built-in voices, or 30+ voiced scenes a month on Pro. Line Learner AI gives each character an English AI voice. Offbook casts realistic voices for every role but yours. Whichever app reads, you still do the talking. A [University of Waterloo study](https://uwaterloo.ca/news/news/study-finds-reading-information-aloud-yourself-improves) by Noah Forrin and Colin MacLeod had 95 people learn written material in different ways, and reading aloud in real time was remembered best, so treat any playback of your own lines as a first listen, then say them yourself. ## How Each App Knows You Finished blablabla's website and App Store listing say it listens and moves on when you finish your line, and you can also tap to continue. Its [Google Play listing](https://play.google.com/store/apps/details?id=com.sayblablabla.app) describes it the other way around: tap to continue, or turn on automatic advance with speech detection. If you're on Android, check that setting before your first run. Line Learner AI's App Store listing says its practice mode listens as you go. Run a short scene to see how it moves to your next cue before you rely on it for an audition. Offbook listens while you say your line and plays the next cue when it detects you've finished. Offbook can also auto-advance after 1 to 6 seconds of silence. Strict matching holds you close to the script, Lenient has a 0-100 slider for when you're still finding the words, and Manual never moves on by itself. ## Getting Your Script In Before you subscribe, open your PDF and try to select one word. If the word highlights, the file has real text. If nothing highlights, or only a box appears, it's a scan. A scan rules out Line Learner AI, which doesn't support scanned PDFs; it imports PDF, Fountain, and Final Draft. blablabla takes photos, DOCX, and pasted text as well. Offbook reads photos of the pages too, and one scene holds up to 50 pages or about 10,000 words, with the page picker splitting up to 150 pages into 10 scenes. ## What $69.99 a Year Buys Line Learner AI is $12.99 a month or $69.99 a year. blablabla Pro is $69.99 a year, or $6.99 a month in the US App Store, for 30+ voiced scenes a month at about 1,500 characters each, which comes to about 45,000 characters a month.
