The best AI speech recognition, translation, and multilingual dubbing solution 🚀
Voice-Pro is a state-of-the-art web app that transforms multimedia content creation. It integrates YouTube video downloading, voice separation, speech recognition, translation, and text-to-speech into a single, powerful tool for creators, researchers, and multilingual professionals.
- 🔊 Top-tier speech recognition: Whisper, Faster-Whisper, Whisper-Timestamped
- 🎤 Zero-shot voice cloning: F5-TTS, E2-TTS, CosyVoice (incl. Fun-CosyVoice3 — Korean and 8 more languages)
- 📢 Multilingual text-to-speech: Edge-TTS, kokoro (optional Azure TTS with your own keys — see Azure services)
- 🎥 YouTube processing & audio extraction: yt-dlp
- 🌍 Instant translation for 100+ languages: Deep-Translator (optional Azure Translator with your own keys)
A robust alternative to ElevenLabs, Voice-Pro empowers podcasters, developers, and creators with advanced voice solutions.
- Due to WeConnect development work, Voice-Pro development and updates are not possible for the time being.
- We have made all Voice-Pro code open source and completely free. Voice-Pro can now be freely distributed and modified by anyone.
- It works well on Windows with NVIDIA GPU. Operation on Mac and Linux has not been verified.
- Please leave your requests on the
or
pages.
- Troubleshooting: In most cases, issues can be resolved by deleting the
installer_filesfolder and then runningstart.batagain (a clean reinstall takes only a few minutes; downloaded AI models inmodel/are kept). Errors are shown in the WebUI as red toasts that stay until closed.
version 4.0
- ⚡ Migrated the installer from Miniconda/pip to uv — dramatically faster, fully reproducible installs from a committed
uv.lock. Everything stays insideinstaller_files/(uv, Python, packages). - 🐍 Upgraded runtime: Python 3.12, Torch 2.8.0+cu128 (RTX 50-series supported), Gradio 6.20.
- 🎙️ Latest ASR stack: 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).
- 🗣️ Latest TTS stack: 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).
- 🧹 CUDA Toolkit and Visual Studio Build Tools are no longer required — all dependencies ship prebuilt wheels, and PyTorch bundles the CUDA runtime.
- 🛡️ Friendly to restricted / corporate PCs: no administrator rights needed —
start.batauto-downloads a portable ffmpeg if it is not installed, Whisper model downloads self-heal after interrupted/corrupted transfers, and translation automatically retries with backoff when the network rate-limits the free Google endpoint (failed lines are reported, originals kept). - 🚨 Errors are now visible in the WebUI: every failure shows a red error toast that stays on screen until you close it (previously a 10-second warning that was easy to miss), with actionable messages for common causes (missing ffmpeg, no media registered, etc.).
- 🖥️ UI: migrated to Gradio 6 (full-width layout for all tabs, subtitle tracks shown directly in the video players).
- 🧽
uninstall.batno longer requires administrator rights and no longer force-reboots;uninstall.bat silentruns unattended.

- OS: Windows 10/11 (64-bit), Linux, Mac (Apple Silicon)
- GPU: NVIDIA GPU with a recent driver (>= 570 recommended; RTX 50-series supported). CUDA Toolkit installation is NOT required.
- VRAM: 4GB+ (8GB+ preferred)
- RAM: 4GB+
- Storage: 20GB+ free space
- Internet: Required
Install Voice-Pro with ease using configure.bat and start.bat (use configure.sh and start.sh on Mac/Linux).
- Clone or download the latest release (Source code (zip)) from
git clone https://github.com/abus-aikorea/voice-pro.git- 🚀 configure.bat (optional)
- Sets up git and ffmpeg system-wide (CUDA Toolkit / Visual Studio are no longer needed)
- Requires administrator rights; run once
- No admin rights? Skip it — start.bat downloads a portable ffmpeg automatically
- 🚀 start.bat
- Launches Voice-Pro WebUI
- First run downloads uv + Python 3.12 and installs all dependencies from the lockfile (minutes, not hours), then downloads AI models (~10GB — this is the slow part)
- GPU/CPU is auto-detected; override with the
GPU_CHOICEenvironment variable (G=NVIDIA,C=CPU) or by deletinginstaller_files\gpu_choice.txt - Retry after deleting installer_files if issues arise
- 🚀 update.bat: Re-syncs the Python environment exactly to the committed lockfile (fast)
- Run uninstall.bat or delete the folder (portable install)
- No administrator rights required; add
silentfor unattended removal (uninstall.bat silent) - Only the
installer_filesfolder is removed — yourmodel/andworkspace/folders are kept
By default Voice-Pro uses free services: Deep-Translator (Google's free web endpoint) for translation and Edge-TTS for speech synthesis. If you have your own Microsoft Azure subscription, you can switch both to the Azure APIs:
- Copy
.env.exampleto.envin the project root:copy .env.example .env # Windows cp .env.example .env # Mac/Linux
- Fill in your Azure credentials:
# Azure Speech Service (TTS) AZURE_SPEECH_KEY=your_azure_speech_key_here AZURE_SPEECH_REGION=eastus # Azure Translator Service AZURE_TRANSLATOR_KEY=your_azure_translator_key_here AZURE_TRANSLATOR_ENDPOINT=https://your-translator-resource.cognitiveservices.azure.com/ AZURE_TRANSLATOR_REGION=eastus
- Restart Voice-Pro. Valid keys are detected automatically at startup — translation switches to Azure Translator and the first Speech Generation tab becomes Azure-TTS.
When is this worth setting up?
- 🏢 Corporate / restricted networks: security appliances often rate-limit or block the free
translate.google.comendpoint, which slows down or fails long subtitle translations. Voice-Pro retries with backoff and keeps the original text for failed lines (you will see a warning with the failure count), but Azure Translator avoids the problem entirely. - 🗣️ Higher-quality/consistent TTS voices and higher rate limits.
- Do NOT commit
.envto version control — it contains your private keys.
- Close the Windows-Commnad window and run start.bat again.
- Run the browser directly and enter the address displayed in the Windows-Command window (e.g. http://127.0.0.1:7870) in the address bar.
- Check the GPU memory status in Windows Task Manager - Performance tab.
- Set the Denoise level to 0 or 1. Denoise level 2 requires at least 8GB of GPU memory.
- Set Compute Type to int type. The float type has better quality, but requires more GPU memory.
- The quality of subtitles tends to improve with larger Whisper models, but this is not necessarily the case. large > medium > small > base > tiny
- Among compute types, float type has good performance. The int type is a model that reduces GPU usage and increases speed through model quantization. On the other hand, performance decreases.
- If you increase the denoise level, more background sounds will be removed, and only the remaining voice will be used for voice recognition. It does not always guarantee good results.
- Due to WeConnect development work, there will be no Voice-Pro updates for the time being.
- All Voice-Pro code has been made open source. It is now completely free to use.
- WeConnect is a communication platform for global cultural exchange.
