OpenAI's automatic speech recognition model supporting 97 languages with high accuracy transcription.
OpenAI's Whisper API provides robust automatic speech recognition (ASR) trained on 680,000 hours of multilingual audio data, supporting transcription and translation across 97 languages with strong accuracy even in challenging conditions. OpenAI has since added the newer, more accurate gpt-4o-transcribe and gpt-4o-mini-transcribe models, which are now recommended for most new transcription workloads.
Features include audio transcription, automatic language detection, speech-to-English translation, timestamp generation at word and segment level, and multiple output format options. Whisper handles diverse accents, background noise, and technical terminology effectively.
Developers building voice-enabled applications, transcription services, subtitle generators, and multilingual communication tools rely on Whisper for accurate, affordable speech processing. The API accepts various audio formats with a simple request interface.
