Faster Whisper
faster-whisper is a reimplementation of OpenAI's Whisper model using CTranslate2, which is a fast inference engine for Transformer models. This implementation is up to 4 times faster than openai/whisper for the same accuracy while using less memory. The efficiency can be further improved with 8-bit quantization on both CPU and GPU. For reference, here's the time and memory usage that are required to transcribe 13 minutes of audio using different implementations: openai/whisper@v20240930 whisper.cpp@v1.7.2 transformers@v4.46.3 faster-whisper@v1.1.0
