Use case
Bilingual captions for online classes and lectures
Give online classes bilingual live captions from the meeting tab, keep course terms consistent with a glossary, and share an edited transcript.
TanLens gives an online class live captions in two languages at once. The teacher runs the meeting in Chrome or Edge, the extension captures the meeting tab, and students see the original speech with a translation underneath. After class, the transcript can be corrected and shared as notes, subtitles or a text file.
01The meeting tab is the classroom
Open the class in Google Meet, Zoom or Microsoft Teams in the browser, keep that tab active, and start the TanLens session. Captions appear on the teacher’s screen, so they can be shared in the meeting like any other window; students who need their own language view can join a broadcast room when the plan includes it. The target language is fixed for the session, which keeps terminology consistent across the lesson. Text on slides and in the chat is not translated, because TanLens only reads audio.
02A transcript students can study
Save the transcript after class, then correct the terms students will search for. A glossary is worth setting up before the first lesson: course names, acronyms, formulas read aloud and the spelling of authors are all easy for a speech model to get wrong. Export VTT if the recording will be published with captions, SRT if it goes into a video editor, or TXT for a reading handout. Tell students that captions are generated and may contain errors, especially when several people speak at once.
