Polyglot 1.10 · Prepared sample project
Start with a short, useful passage
For language study, a short video with clear speech gives you room to compare wording carefully. Use a recording you own or are authorized to process. Generate subtitles from supported speech, or import an existing SRT or VTT matched to the video you will watch.
Review the original before translating. Correct names, missing words and punctuation so the second language starts from a reliable source. Imported subtitle text can be translated independently of speech-recognition language support; the two capabilities are separate.
Find your way in Polyglot
Generate an original in Create or import timed text through Translate. Open the saved track in Files, add a translation and compare wording in the continuous editor. Export a bilingual pair from its project when both languages are ready.
Compare meaning across the two tracks
Select a target language and complete its translation. Read the original and translated cues together in the editor. Idioms, pronouns and cultural references deserve extra attention because a fluent translation may still make a poor teaching example.
You can edit a translation without replacing the source. If you later change an original line, Polyglot keeps the completed translation and marks it for review. Decide whether to keep the wording or refresh it; the app does not silently overwrite those decisions.
Put two languages in each cue
Open Export, select SRT subtitles or WebVTT subtitles, and choose the completed translation. Enable Include original and translation together. Choose whether the original appears first. Each exported cue combines the original and one translation under the same timing.
Export all creates a separate bilingual pair for each completed language. It does not put several translations into one cue. The output is plain text, so font, position and visual treatment depend on the player. Captions are not burned into the video.
Check reading speed on the actual screen
Play the exported subtitles where you intend to study or teach. Two languages take more space, and longer text can wrap. Check a dense sentence on a smaller screen as well as on your main display. Shorten wording carefully where necessary while preserving meaning.
For a lesson handout, export the reviewed translation separately as readable TXT. Keep the bilingual subtitle file for playback and the text document for discussion.
Bilingual export keeps cue timing; it does not extend reading duration automatically. If the whole track is delayed, a fixed offset can move it. More complex retiming needs a suitable editor. Bilingual exports of completed tracks remain free after the trial. Creating new translations is unlimited for seven days and requires Pro afterward.
