## Overview

faster-whisper runs compatible Whisper models through CTranslate2 to produce text and timed segments. Its Python interface supports batched transcription, word timestamps, Silero VAD filtering and language detection, with quantized CPU or GPU computation. It suits self-managed services and offline batch processing. Model files must be prepared, and GPU acceleration requires matching CUDA, cuDNN and CTranslate2 versions; speed depends on the model and hardware.
