Frequently Asked Questions
Everything you need to know about Line Echo
Getting Started
What is Line Echo?
Line Echo is an AI-powered script rehearsal platform that helps actors practice their lines. Upload a screenplay, select your character, and rehearse with AI scene partners that voice other characters using realistic AI-generated voices.
How do I get started?
Is there a free trial?
Yes! Our free Audition tier lets you practice with 2 active scripts, 3 uploads per month, and 30 lines per script. No credit card required to start.
What file formats do you support?
We support PDF files and images (PNG, JPG) of scanned scripts. Our AI extracts dialogue, characters, and scene information automatically.
Rehearsal Features
How does the AI scene partner work?
After uploading your script and selecting your character, the AI takes on all other roles. When it's another character's turn to speak, you'll hear their lines read aloud with realistic AI speech. You can also adjust playback speed (0.5x-2x) to practice at your own pace.
What voices are available?
We offer Standard voices (free) and Premium voices (paid tiers). Premium voices include natural-sounding options with emotional depth and prosody for realistic practice.
How does speech recognition work?
We use on-device speech recognition that runs locally in your browser. Your voice is never sent to external servers. Simply speak your lines, and our matcher compares what you said to the script with forgiving matching for contractions, filler words, and common mispronunciations.
Can I edit script lines?
Yes! You can edit, add, or remove lines from your scripts. You can also reorder lines via drag-and-drop and add parenthetical direction notes.
Can I save my progress?
Absolutely. Your rehearsal progress is automatically saved. You can stop mid-session and resume exactly where you left off, including which line you're on and voice settings.
