whisper-ctranslate2 0.1.1

Whisper command line client that uses CTranslate2

Introduction

Whisper command line client compatible with original OpenAI client based on CTranslate2.

It uses CTranslate2 and Faster-whisper Whisper implementation that is up to 4 times faster than openai/whisper for the same accuracy while using less memory.

Goals of the project:

• Provide an easy way to use the CTranslate2 Whisper implementation
• Easy the migration for people using OpenAI Whisper CLI
