🎯 The Problem It Solves

You want Whisper-quality speech recognition but can't rely on GPU. Whisper.cpp runs the same Whisper models on CPU with impressive speed, making voice AI feasible on any hardware.

🔧 How It Works

Whisper.cpp is a C++ port of OpenAI's Whisper that runs efficiently on CPU. It uses GGML for model quantization, achieving 2-4x real-time speed on modern CPUs. Supports all Whisper models from tiny to large.

🚀 Installation & Quick Start

Installation

git clone https://github.com/ggerganov/whisper.cpp.git
cd whisper.cpp
make
bash ./models/download-ggml-model.sh small

Quick Start

  1. Clone and make
  2. Download a model
  3. Transcribe with ./main -f audio.wav
  4. Stream real-time from microphone

✅ Pros

  • •Best CPU performance
  • •No GPU required
  • •All model sizes
  • •Real-time streaming
  • •Free and open-source

❌ Cons

  • •Slower than GPU versions
  • •Large models still benefit from GPU
  • •Setup requires C++ knowledge

💬 Practitioner Verdict

"Whisper.cpp is the best way to run Whisper on CPU. If you don't have GPU, this is your speech recognition solution."
