Whisper is a Speech-To-Text model from OpenAI. Given an audio file with voice data it produces human speech recognition text with per sentence timestamps. There are different model sizes (small, base, large, etc.) and variants for English, see more at deepinfra.com. By default, Whisper produces by sentence timestamp segmentation. We also host whisper-timestamped that can provide timestamps for words in the audio. You can use it with our REST API. Here's how to use it:
curl -X POST \
-F "audio=@/home/user/all-in-01.mp3" \
-H "Authorization: Bearer YOUR_API_KEY" \
'https://api.deepinfra.com/v1/inference/openai/whisper-timestamped-medium.en'
