GPU Acceleration

Speed up transcription 5-10x with NVIDIA GPU acceleration.

​
Requirements

  • NVIDIA GPU (GTX 1060 or newer recommended)
  • CUDA 12.0 or later
  • cuDNN 9.5.1 or later

​
Installation

​
Windows

  1. Download CUDA Toolkit 12.x
  2. Run the installer and follow the prompts
  3. Restart your computer
  4. Echophrase will automatically detect and use your GPU

​
Linux

# Ubuntu/Debian
sudo apt install nvidia-cuda-toolkit

# Or download from NVIDIA
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt update
sudo apt install cuda

​
Verifying GPU Usage

  1. Open Echophrase settings
  2. Check System Info — it should show your GPU model
  3. Look for “CUDA” in the acceleration status

​
Troubleshooting

If GPU acceleration isn’t working:
  • Ensure your NVIDIA drivers are up to date
  • Verify CUDA is installed: nvcc --version
  • Check GPU Troubleshooting for more help
