From a5bdfc75e5362df6e7ca42852d4e45cba58953f7 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 30 Jan 2026 10:29:39 +0000 Subject: [PATCH 1/4] Add Voice Reporting (Whisper) and Vandalism Detection UI - Added `transcribe_audio` to `backend/hf_api_service.py` using `openai/whisper-large-v3-turbo`. - Added `/api/transcribe-audio` endpoint to `backend/main.py`. - Updated `frontend/src/components/VoiceInput.jsx` to use `MediaRecorder` and backend transcription. - Added "Vandalism" category to `Home.jsx` and `ReportForm.jsx`. - Fixed `frontend/src/api/misc.js` to correctly use `postForm` for file uploads. - Verified functionality with script and UI verification.
