Test it with any Hindi YouTube video

1 · Solo test 2 min

1. In a new Chrome tab, open YouTube and play a Hindi talk with one clear speaker (search “Hindi pravachan” or “Hindi motivational speech”).
2. Open solo mode in another tab and press Share a tab & translate.
3. In Chrome's picker, choose the Chrome tab option, select the YouTube tab, check Also share tab audio, then Share.
4. Come back to the solo tab.

Pass if

• The audio level bar moves with the speaker's voice
• Grey Hindi text appears while they talk
• An English line appears at each pause

2 · Room test with a phone 5 min

1. Keep the YouTube tab playing. Open Host a room, name it, press Start translating and share the YouTube tab as before.
2. Scan the QR code with your phone (on mobile data too, to prove it works from anywhere).
3. On the phone, tap Listen with earbuds in.
4. Open the same link on a second device or ask a friend abroad to open it.

Pass if

• The phone shows the same English lines as the host screen
• “Listening now” on the host counts each device
• Read-aloud speaks each new line

3 · Sync test 3 min

Listeners abroad watch the YouTube stream, which runs 15–60 seconds behind the venue. Subtitles from the host can arrive before the viewer hears the words.

1. On the phone, open the ⚙ panel and move Sync with video to about 20s.
2. Adjust until English lines appear right after the Hindi words are heard.

On the event day, tell listeners the delay that worked in your test.

4 · Endurance test 30–60 min

1. Play a long Hindi video (an hour-long talk) in a host room.
2. Leave it running; plug the laptop in and turn off sleep.
3. At the end, press Download transcript and skim it for gaps or wrong meaning.

Have a Hindi speaker read 10 random lines and judge whether the English keeps the meaning.
