WhisperAPI is a developer-focused API for fast audio and video transcription powered by the OpenAI Whisper model. It’s designed to add speech-to-text to products without running your own infrastructure or managing model setup.
Speech recognition with OpenAI Whisper
WhisperAPI runs on Whisper Large-v2 and is built to handle recordings of different lengths and challenging audio. You can send a file or a link and receive text output with or without timestamps, in multiple formats.
Use cases and integrations
Common ways to use the API include:
- Generating subtitles for video
- Transcribing podcasts
- Converting calls, lectures, and interviews into text
- Connecting transcription to internal analytics systems
- Embedding speech-to-text in web apps and mobile clients
Pricing and getting started
You can start without a bank card and use a daily free transcription limit. After that, pricing is pay-as-you-go per minute. Documentation and request examples help you integrate the API into an existing stack and automate speech processing.
