## What is Langplayer?

A whole two-hour film — five minutes at a time, all the way through.

Langplayer loops sections of your own audio against its script. Repeat one
sentence until you actually hear it, then move to the next.

■ A-B repeat
· Mark A and B on the waveform and that stretch loops forever
· Nudge either point in 0.1-second steps
· Choose how many repeats and how long the silence between them is — say it out loud while it waits

■ Listen with the script beside you
· Subtitles (.srt .vtt), plain text (.txt) or a PDF all work as a script
· Paste a news transcript straight from the web
· Search a line you half-remember and it scrolls right to it

■ Keep the parts that were hard
· Name a segment and jump back to it any time
· Link it to a script page and the script follows along

■ 0.5× to 2×
· Pitch stays natural. Slow down to catch it, speed up to check it

■ No servers, no accounts
· Nothing to sign up for. Your materials, scripts and progress stay on your device
· No limit on how many materials you add, and every feature is open
· Free with ads; one payment removes them for good

Languages: 한국어 · English · 日本語 · Español · Français
