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_files folder and then running start.bat again (a clean reinstall takes only a few minutes; downloaded AI models in model/ are kept). Errors are shown in the WebUI as red toasts that stay until closed.

• 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

1. 🚀 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
2. 🚀 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_CHOICE environment variable (G=NVIDIA, C=CPU) or by deleting installer_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 silent for unattended removal (uninstall.bat silent)
• Only the installer_files folder is removed — your model/ and workspace/ 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:

1. Copy .env.example to .env in the project root:

   copy .env.example .env     # Windows
   cp .env.example .env       # Mac/Linux

2. 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

3. 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.com endpoint, 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 .env to 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.

The following table lists SaaS platforms supporting subtitling, translation, and text-to-speech (TTS/dubbing) functionalities. Costs are calculated for processing a 60-minute Korean video, including subtitle generation, English translation, and English dubbing, based on the latest available pricing data as of April 15, 2025.

• Maestra: Premium Plan ($158/month, 1200 credits). 60-min video: 60 credits (subtitles) + 60 credits (translation) + 60 credits (dubbing) = 180 credits. Cost = (180/1200) * $158 = $23.70.
• Kapwing: Pro plan (~$24/month, limited minutes). Estimated $0.50~$0.67/min for subtitles+translation+dubbing (based on per-minute pricing trends). 60-min cost: $30~$40. Exact pricing requires confirmation.
• VEED.IO: Pro plan (~$24/month). Subtitles+translation estimated at $0.40~$0.60/min. No TTS, so partial processing. 60-min cost: $24~$36. Confirm at veed.io.
• HappyScribe: Pay-as-you-go (~$0.20/min transcription, $0.20/min translation, $0.20/min dubbing). 60-min cost: $36~$48 (assuming combined services). Confirm at happyscribe.com.
• Sonix: Standard plan (~$10/hour transcription, additional for translation/dubbing). Estimated $0.50~$0.67/min total. 60-min cost: $30~$40. Confirm at sonix.ai.

• Transkriptor: Pay-as-you-go ($0.05~$0.10/min transcription, similar for translation). No TTS, so partial processing. 60-min cost: $12~$18. Confirm at transkriptor.com.

• Cost for 60-min Video: Costs are approximate and assume processing a 60-minute Korean video for subtitles, English translation, and English dubbing (where available). Platforms without TTS (e.g., VEED.IO, Transkriptor) reflect partial processing costs.
• Language Support: Most platforms support Korean and English. Verify specific language availability on their websites.
• Use Cases:
  • Media/Entertainment: AppTek, Maestra
  • Social Media: Kapwing, VEED.IO
