TinyCaptioner — Shows a text summary caption when the sound is closed: Description: when the tab plays audio but the user mutes the speaker, the extension takes the first 5–10 seconds (client-side) and shows a summary transcript (offline/preliminary). Features: “Quick summary” button, shows a text popup. Note: because the exact speech→text conversion requires a server; the simple version can use heuristics (vocal energy → “Voice”, “Music”, etc.). (If the user wants to upgrade, it is suggested to integrate the speech-to-text API.) Hint: the basic version is a status summary indicator, not a full transcript to avoid needs for external APIs.
