Voice-Pro v4.0.0

Voice-Pro is now fully open source and completely free. This release rebuilds the entire installation stack and modernizes every AI engine.

⚡ Highlights

• Installer migrated from Miniconda/pip to uv — installation now takes minutes, not hours, and is fully reproducible from the committed uv.lock. Everything stays inside installer_files/ (uv, Python, packages) — a truly portable install.
• No administrator rights needed — configure.bat is now optional. start.bat auto-downloads a portable ffmpeg if it is not installed. CUDA Toolkit and Visual Studio Build Tools are no longer required (PyTorch bundles the CUDA runtime; all dependencies ship prebuilt wheels).
• Upgraded runtime: Python 3.12, Torch 2.8.0+cu128 (RTX 50-series supported), Gradio 6.20.

🎙️ Latest AI engines

• ASR: faster-whisper 1.2.1 (large-v3-turbo, distil-large-v3.5), openai-whisper 20250625, whisper-timestamped 1.15.9. whisperX was removed (its dependency pins blocked the Gradio 6 upgrade; existing configs fall back to faster-whisper).
• TTS: F5-TTS 1.1.21, kokoro 0.9.4, edge-tts 7.x, and re-vendored CosyVoice (upstream main).
• 🇰🇷 New optional TTS model: Fun-CosyVoice3-0.5B — 9 languages including Korean, selectable in the CosyVoice tab (downloads from the official HF repo on first use).

🛡️ Restricted / corporate PC friendly

• Whisper model downloads self-heal after interrupted/corrupted transfers.
• Translation automatically retries with backoff when the network rate-limits the free Google endpoint (failed lines are reported, originals kept).
• Optional Azure Translator / Azure TTS with your own keys via .env — see the "Azure services" section in the README.

🖥️ UI improvements

• Migrated to Gradio 6: full-width layout for all tabs, subtitle tracks shown directly in the video players.
• Errors are now visible: every failure shows a red error toast that stays on screen until you close it, with actionable messages for common causes (missing ffmpeg, no media registered, etc.).
• uninstall.bat no longer requires administrator rights and no longer force-reboots; uninstall.bat silent runs unattended.

📀 Install / Upgrade

• Fresh install: clone or download the source, then run start.bat. First run installs uv + Python 3.12 + all dependencies from the lockfile (minutes), then downloads AI models (~10GB — this is the slow part).
• Upgrading from v3.x: delete the installer_files/ folder and run start.bat again. Your model/ and workspace/ folders are kept.
