Whisper is an automatic speech recognition (ASR) system developed by OpenAI. Whisper is trained on a large and diverse dataset of multilingual and multitask supervised data collected from the web, making it robust and versatile for various speech recognition tasks.

​
Key Capabilities

  • Multilingual Support: Whisper supports numerous languages, allowing it to transcribe speech from diverse linguistic backgrounds.
  • Robust Performance: It is capable of handling different acoustic settings, including noisy environments and varied accents.
  • Automatic Language Detection: The model can automatically detect the language spoken in the audio input.
  • Versatility: Suitable for transcribing lectures, meetings, podcasts, conversations, and more.
  • Open Source: Available on GitHub, enabling developers to access, modify, and contribute to the codebase.

​
Metrics

  • WER (Word Error Rate): Whisper demonstrates a low word error rate across multiple languages and benchmarks, indicating high transcription accuracy.
  • Languages Supported: Over 50 languages.
  • Training Dataset: 680,000 hours of multilingual and multitask supervised data.
