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 Bring your own audio and script — this app does not provide content.
