OpenAI's state-of-the-art speech recognition API for transcription and translation.
OpenAI Whisper is a general-purpose speech recognition model trained on 680,000 hours of multilingual audio data, delivering near-human transcription accuracy across 99 languages. The API supports audio transcription, translation into English, and timestamp generation, making it ideal for building subtitles, meeting notes, voice search, and accessibility tools. Whisper's transformer architecture handles diverse accents, technical jargon, background noise, and mixed-language speech far better than legacy ASR systems.
