+
+    faster-whisper is a reimplementation of OpenAI's Whisper model using CTranslate2,
+    which 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.
+
+    It can automatically detect the following 14 languages and transcribe the text
+    into their respective languages: en, zh, fr, de, ja, ko, ru, es, th, it, pt, vi,
+    ar, tr.
+
+    The gitbub repository for faster-whisper is :
+    https://github.com/SYSTRAN/faster-whisper
+
+    Example: Load a YouTube video and transcribe the video speech into a document.
