Frequently Asked Questions

Line Echo has a free tier called Audition that does not expire and does not require a credit card. It includes 2 active scripts, 3 uploads per month, 50 lines per script, and 150 new AI voice lines a month with standard voices; replaying lines you've already heard is free and unlimited. Paid plans start at $19 per month.

Yes. Self-tape preparation is one of the most common uses for Line Echo, because a reader is often unavailable when sides arrive on short notice. Upload the sides, assign a voice to the reader's part, and rehearse the scene as many times as you need before you record.

Line Echo accepts PDF files and images in PNG or JPG format, including photos of printed script pages. The AI extracts dialogue, characters, and scene information automatically, so no manual formatting is required.

Line Echo offers 10 standard voices on the free tier and more than 28 premium voices on paid tiers. Premium voices use natural prosody and adjust their delivery to the emotion of each line, across 16 sentiment categories including angry, tender, sarcastic, hopeful, and playful.

Line Echo has a manual mode that advances the script with a tap or click instead of your voice. Everything else works the same way, so you can rehearse in a quiet room or anywhere speaking aloud is not practical.

Yes. You can edit, add, or remove lines, reorder them by dragging, and add parenthetical direction notes. This is useful when the AI misreads a scanned page, or when your sides differ from the version you uploaded.

Yes. Working Actor and Studio are both available on annual billing, which costs less than paying month to month. Current annual prices are shown on the pricing page.

You can change plans at any time. Upgrades take effect immediately so you get the higher limits straight away, and downgrades apply at the start of your next billing cycle so you keep what you already paid for.

No. Only new AI voice lines count. Once a line has been voiced, you can replay it as often as you like, in any session, for free. Editing a line or choosing a different voice for a character creates new audio, which counts as a new line.

Line Echo accepts all major credit cards, processed securely through Polar. Card details are handled by Polar and never touch Line Echo's servers.

You can cancel at any time from your subscription settings, with no cancellation fee. Access continues until the end of the billing period you have already paid for.

No. All payments are final and non-refundable, including renewals and partial billing periods. The free Audition plan lets you try Line Echo before paying, and cancelling stops the next renewal while you keep access until the end of the period you paid for.

No. Speech recognition runs entirely on-device in your browser, so your voice is never transmitted to or stored on Line Echo's servers. There is no recording to delete because none is ever made.

Your scripts are encrypted in transit and at rest and stay private to your account. To read them and voice your scene partners, they are sent to the AI services we use, under business terms that do not use your content to train their models. We never use your scripts for training, advertising or anything other than your rehearsals.

Only you. Uploaded scripts are tied to your account and are not visible to other users or published anywhere.

Yes. Line Echo runs in the mobile browser on iPhone and Android with no app to install, so you can rehearse on a phone or tablet. The speech recognition model downloads once and is cached for later sessions.

Line Echo supports current versions of Chrome, Firefox, Safari, and Edge on both desktop and mobile. Chrome gives the most reliable microphone behaviour.

Yes, an internet connection is required. Scripts and generated voice audio are fetched from Line Echo's servers, though the speech recognition itself runs locally on your device once the model has loaded.

Line Echo supports scripts in English, Spanish, French, German, Italian, Portuguese, Russian, Chinese (Mandarin), Japanese, Korean, Turkish, Swedish, Dutch, Hindi, Indonesian and Ukrainian. The AI scene partner reads the other characters in your script's language. Speech recognition is English-only for now, so for scripts in other languages you tap to move on after each of your lines instead of the app listening for them.

Yes. You can select any microphone connected to your device during mic setup, and Line Echo uses your system default if you do not choose one.
