OpenAI's open-weight Whisper Large V3, which transcribes speech in close to a hundred languages and returns timed segments for subtitles.
From OpenAI, Whisper Large V3 is a cloud speech-to-text model. It transcribes spoken audio into written text. It handles multiple spoken languages and can return timestamped segments along with the transcript. It also supports an optional text prompt that guides the spelling of names and terms. It runs through OpenRouter and Replicate using your own API key, from about $0.00045 per minute of audio.

Samples
Transcribed by Whisper Large V3 via OpenRouter. The same three clips go to every speech-to-text model in the catalog, so the only thing that changes between two models’ transcripts is the model. The clips are synthetic speech made with ElevenLabs v4, and a word that differs from the spoken script is underlined. The numbers clip is left unmarked, since “12” and “twelve” are both right.
