Note: For all these methods below, keep in mind the above note regarding CUDA versions.

Use Docker

cuBLAS is included in the official NVIDIA CUDA runtime Docker images, such as nvidia/cuda:12.8.1-runtime-ubuntu22.04.

Install with pip (Linux only)

On Linux cuBLAS can be installed with pip. Note that LD_LIBRARY_PATH must be set before launching Python.

pip install nvidia-cublas-cu12

export LD_LIBRARY_PATH=`python3 -c 'import os; import nvidia.cublas.lib; print(os.path.dirname(nvidia.cublas.lib.__file__))'`

Install the master branch

pip install --force-reinstall "faster-whisper2 @ https://github.com/BBC-Esq/faster-whisper2/archive/refs/heads/master.tar.gz"

Install a specific commit

pip install --force-reinstall "faster-whisper2 @ https://github.com/BBC-Esq/faster-whisper2/archive/a4f1cc8f11433e454c3934442b5e1a4ed5e865c3.tar.gz"

Here is a non exhaustive list of open-source projects using faster-whisper. Feel free to add your project to the list!

• speaches is an OpenAI compatible server using faster-whisper. It's easily deployable with Docker, works with OpenAI SDKs/CLI, supports streaming, and live transcription.
• WhisperX is an award-winning Python library that offers speaker diarization and accurate word-level timestamps using wav2vec2 alignment
• whisper-ctranslate2 is a command line client based on faster-whisper and compatible with the original client from openai/whisper.
• whisper-diarize is a speaker diarization tool that is based on faster-whisper and NVIDIA NeMo.
• whisper-standalone-win Standalone CLI executables of faster-whisper for Windows, Linux & macOS.
• asr-sd-pipeline provides a scalable, modular, end to end multi-speaker speech to text solution implemented using AzureML pipelines.
• Open-Lyrics is a Python library that transcribes voice files using faster-whisper, and translates/polishes the resulting text into .lrc files in the desired language using OpenAI-GPT.
• wscribe is a flexible transcript generation tool supporting faster-whisper, it can export word level transcript and the exported transcript then can be edited with wscribe-editor
• aTrain is a graphical user interface implementation of faster-whisper developed at the BANDAS-Center at the University of Graz for transcription and diarization in Windows (Windows Store App) and Linux.
• Whisper-Streaming implements real-time mode for offline Whisper-like speech-to-text models with faster-whisper as the most recommended back-end. It implements a streaming policy with self-adaptive latency based on the actual source complexity, and demonstrates the state of the art.
• WhisperLive is a nearly-live implementation of OpenAI's Whisper which uses faster-whisper as the backend to transcribe audio in real-time.
• Faster-Whisper-Transcriber is a simple but reliable voice transcriber that provides a user-friendly interface.
• Open-dubbing is open dubbing is an AI dubbing system which uses machine learning models to automatically translate and synchronize audio dialogue into different languages.
• Whisper-FastAPI whisper-fastapi is a very simple script that provides an API backend compatible with OpenAI, HomeAssistant, and Konele (Android voice typing) formats.

When you specify a compute_type, faster-whisper2 validates that it is compatible with your device before downloading anything. If an incompatible combination is detected, a clear error is raised. For quantized types (e.g. int8), the library automatically downloads the best source precision for your hardware and CTranslate2 handles the runtime conversion.
