Whisper whisper

개요 overview

Whisper 모델은 Alec Radford, Jong Wook Kim, Tao Xu, Greg Brockman, Christine McLeavey, Ilya Sutskever에 의해 Robust Speech Recognition via Large-Scale Weak Supervision에서 제안되었습니다.

논문의 초록은 다음과 같습니다:

우리는 인터넷에서 대량의 오디오를 글로 옮긴 것을 예측하도록 간단히 훈련된 음성 처리 시스템의 성능을 연구합니다. 68만 시간의 다국어 및 다중 작업 지도(multitask supervision)에 확장했을 때, 결과 모델은 표준 벤치마크에 잘 일반화되며, 미세 조정이 필요 없는 제로샷 전송 설정에서 이전의 완전히 지도된(fully-supervised) 결과와 경쟁할 수 있는 경우가 많습니다. 사람과 비교하면, 이 모델은 사람의 정확도와 견고성에 근접합니다. 우리는 강력한 음성 처리를 위한 추가 작업의 기반이 될 모델과 추론 코드를 공개합니다.

팁:

  • 이 모델은 일반적으로 별도의 미세 조정 없이도 잘 작동합니다.

  • 아키텍처는 고전적인 인코더-디코더 아키텍처를 따르기 때문에, 추론을 위해 [~generation.GenerationMixin.generate] 함수를 사용합니다.

  • 현재 추론은 짧은 형식에만 구현되어 있으며, 오디오는 30초 미만의 세그먼트로 미리 분할되어야 합니다. 타임스탬프를 포함한 긴 형식에 대한 추론은 향후 릴리스에서 구현될 예정입니다.

  • [WhisperProcessor]를 사용하여 모델에 사용할 오디오를 준비하고, 예측된 ID를 텍스트로 디코딩할 수 있습니다.

  • 모델과 프로세서를 변환하려면 다음을 사용하는 것이 좋습니다:

python src/transformers/models/whisper/convert_openai_to_hf.py --checkpoint_path "" --pytorch_dump_folder_path "Arthur/whisper-3" --convert_preprocessor True

스크립트는 OpenAI 체크포인트에서 필요한 모든 매개변수를 자동으로 결정합니다. OpenAI 변환을 수행하려면 tiktoken 라이브러리를 설치해야 합니다. 라이브러리를 설치해야 OpenAI 토큰화기를 tokenizers 버전으로 변환할 수 있습니다.

이 모델은 Arthur Zucker에 의해 제공되었습니다. 이 모델의 Tensorflow 버전은 amyeroberts에 의해 제공되었습니다. 원본 코드는 여기에서 찾을 수 있습니다.
