Available Models

The tool offers several model options, including:

• tiny
• base
• small
• medium
• large-v1
• large-v3

Model Characteristics:

• Smaller models (like tiny and base) run faster but have lower transcription accuracy.
• Larger models (like large-v1 and large-v3) have higher accuracy but run slower and may cause browser crashes on lower-performance devices.

How to Use

1. Upload File: Click to select the audio or video file you want to transcribe.
2. Select Model: Choose a suitable model based on your device's performance.
   • Weaker devices are recommended to use tiny or base.
   • Stronger devices can choose small or medium.
   • Avoid selecting excessively large models unless your device has excellent performance, to prevent browser crashes.
3. Select Language: Specify the language of the audio or video.
4. Model Download: The first time you use a model, the tool will download the model files from Hugging Face. Since this website may not be directly accessible in some regions, it is recommended to use a VPN to ensure a smooth download.

Important Notes

• Privacy & Security: After downloading, the model runs entirely locally. Your files will not be uploaded to any server.
• Performance Dependency: Model selection and running speed depend on your device's performance.
• System Recommendations: We recommend using the Chrome browser on Windows or Linux systems. M-series chip support on Mac devices may not be fully optimized.
