What is WhisperAPI?

WhisperAPI is a cutting-edge video and audio transcription API powered by OpenAI's Whisper model. It offers a fast, accurate, and reliable solution for converting speech to text. Whether you're a developer looking to integrate transcription into your application or a business needing to process large volumes of audio and video content, WhisperAPI provides a robust and easy-to-use platform.

How does WhisperAPI work?

WhisperAPI leverages the power of OpenAI's Whisper model to provide accurate and efficient transcription services. The process involves:

  1. File Upload: Users upload their audio or video files to the WhisperAPI platform via the API or the no-code dashboard.
  2. Model Selection: Developers can choose between different Whisper models for speed versus accuracy. Larger models are trained on more data, resulting in higher accuracy but slightly longer processing times.
  3. Transcription: The selected Whisper model processes the audio or video file and generates a text transcription.
  4. Download: Users can download the transcription in multiple formats, including JSON, TEXT, VTT, DOCX, and PDF.

How to use WhisperAPI?

For Developers:

Developers can use the WhisperAPI to integrate transcription capabilities into their applications. The API supports:

  • Direct file uploads and remote URLs
  • Fine-tuning model parameters for specific use cases
  • Processing both video and audio files with the same API

Here's an example of how to use the API with curl:

curl \
  -F "file=@video.mp4" \
  -F "language=en" \
  -F "format=srt" \
  -F "model_size=large-v2" \
  -H "X-API-Key: YOUR_API_KEY" \
