​
GPU Acceleration

​
Vulkan Support

VoiceTypr for Windows uses Vulkan for GPU-accelerated transcription:
  • 5-10x faster than CPU-only mode
  • Works with NVIDIA, AMD, and Intel GPUs
  • Automatic fallback to CPU if GPU unavailable
  • Requires Vulkan Runtime (included in modern graphics drivers)

​
Supported GPUs

  • NVIDIA: GeForce GTX 900 series or newer (Vulkan 1.0+)
  • AMD: Radeon RX 400 series or newer (Vulkan 1.0+)
  • Intel: Arc series, Iris Xe, or UHD Graphics 600+ (Vulkan 1.0+)

​
Smart Installer Detection

The installer automatically:
  1. Detects dedicated GPU (>1 GB VRAM)
  2. Checks for Vulkan Runtime (vulkan-1.dll in System32)
  3. Informs you if GPU acceleration is available
  4. Provides driver update links if Vulkan is missing
From smart-installer-hooks.nsh: 
; GPU detected but Vulkan missing
MessageBox MB_OK|MB_ICONINFORMATION "GPU Acceleration Available

Good news! Your GPU can make VoiceTypr 5-10x faster.

To enable GPU acceleration, please update your graphics drivers:

• NVIDIA: nvidia.com/drivers
• AMD: amd.com/support  
• Intel: intel.com/content/www/us/en/support

Modern graphics drivers include Vulkan Runtime automatically.
After updating, VoiceTypr will use your GPU!"

​
Driver Requirements

For GPU acceleration, you need up-to-date graphics drivers:
Modern graphics drivers include Vulkan Runtime automatically. After updating, VoiceTypr will detect and use your GPU.

​
Checking GPU Status

To verify GPU acceleration is working:
  1. Check VoiceTypr logs after transcription
  2. Look for messages like: "Using Vulkan GPU backend"
  3. CPU fallback messages: "GPU unavailable, using CPU"
Logs are located at: 
%APPDATA%\com.voicetypr.app\logs\

​
Required Permissions

VoiceTypr requires minimal permissions on Windows:

​
Microphone Access

Required for: Recording your voice
  • Prompt appears on first recording attempt
  • Navigate to: Settings → Privacy → Microphone
  • Enable for VoiceTypr

​
No Accessibility Requirement

Unlike macOS, Windows VoiceTypr does not require accessibility permissions for text insertion. It uses standard Windows clipboard and input APIs.
VoiceTypr preserves your original clipboard content and restores it after inserting text.

​
Platform Features

​
Visual C++ Runtime

The installer includes Visual C++ Runtime bundling:
  • Automatically detects if already installed
  • Installs silently if needed
  • Ensures VoiceTypr runs on fresh Windows installations

​
System Tray Integration

VoiceTypr integrates with the Windows system tray:
  • Right-click for quick actions
  • Recent Transcriptions: Copy previous transcriptions
  • Recording Mode: Toggle Push-to-Talk / Toggle mode
  • Model Selection: Switch between AI models
  • Check for Updates: Manual update check

​
Start Menu Integration

  • Launch from Start Menu → VoiceTypr
  • Pin to taskbar for quick access
  • Appears in installed programs list

​
Auto-Start Support

VoiceTypr can start automatically when Windows boots:
  • Settings → General → Launch at Startup
  • Minimizes to system tray on startup
  • No performance impact when idle

​
Model Management

​
Whisper Models

VoiceTypr for Windows uses Whisper models with Vulkan GPU acceleration:
  • Tiny - Fastest, lower accuracy (~75 MB)
  • Base - Balanced speed/accuracy (~142 MB)
  • Small - Recommended for most users (~466 MB)
  • Medium - High accuracy (~1.5 GB)
  • Large - Best accuracy, slower (~2.9 GB)
Parakeet models are macOS-only and use Apple Neural Engine. Windows users should use Whisper models.

​
Performance Characteristics

​
With GPU Acceleration (Vulkan)

  • Transcription Speed: 5-10x real-time
  • Model Loading: 2-5 seconds (first time)
  • Memory Usage: 500 MB - 2 GB (depending on model and VRAM)
  • Best For: Users with dedicated GPUs

​
Without GPU (CPU Only)

  • Transcription Speed: 1-2x real-time (depends on CPU)
  • Model Loading: 3-10 seconds
  • Memory Usage: 200-600 MB
  • Best For: Users without dedicated GPUs or with outdated drivers
VoiceTypr always works - it automatically falls back to CPU mode if GPU acceleration is unavailable.

​
Troubleshooting

​
GPU Acceleration Not Working

Issue: Slow transcription despite having a GPU Solutions:
  1. Update graphics drivers (most common fix):
  2. Verify Vulkan is installed:
    • Check for C:\Windows\System32\vulkan-1.dll
    • Download Vulkan Runtime if missing
  3. Check Windows Event Viewer for VoiceTypr errors

​
Installer Hangs or Fails

Issue: Installation doesn’t complete Solutions:
  1. Run as Administrator: Right-click installer → “Run as administrator”
  2. Disable antivirus temporarily during installation
  3. Check disk space: Ensure 5+ GB free

​
App Won’t Launch

Issue: VoiceTypr doesn’t start after installation Solutions:
  1. Install Visual C++ Runtime manually:
