Faster Whisper Base.en is a converted version of the Whisper base.en model provided in CTranslate2 format for English automatic speech recognition. It addresses the need for accelerated inference on audio transcription tasks compared to the original PyTorch implementation. The model originates from the openai/whisper-base.en checkpoint and is hosted on Hugging Face by Systran.
It can be loaded and run directly in CTranslate2 or in projects built on that library, such as the faster-whisper Python package. An example loads the model with the identifier "base.en", transcribes an audio file such as audio.mp3, and iterates over resulting segments that each contain start time, end time, and recognized text. The conversion process used the ct2-transformers-converter tool with the command that specified the source model, output directory, copied the tokenizer.json file, and applied float16 quantization. Model weights are stored in FP16, though the compute_type option in CTranslate2 allows changing the precision at load time.
The repository carries an MIT license. It is intended for developers integrating English speech-to-text capabilities into applications that require efficient processing of audio files or streams. Delivery occurs as downloadable model files through the Hugging Face model hub, compatible with CTranslate2-based runtimes rather than the native PyTorch version of Whisper.
Faster Whisper Base.en is a Voice, TTS & speech product. It focuses on transcribing English audio files quickly and efficiently using an optimized Whisper model. It is built as an open-source project for developers. Faster Whisper Base.en is open source under the MIT license. Faster Whisper Base.en is available on the web and API.
Behind Faster Whisper Base.en is Systran, and the product first shipped in 2018. Development happens publicly on GitHub with 4.6k stars and 21 commits in the last 90 days. Key capabilities include Speech Recognition, English ASR, and Fast Inference.
