whisper.cpp is a lightweight, C/C++ reimplementation of OpenAI’s Whisper automatic speech recognition (ASR) model—designed for efficient, standalone transcription without external dependencies. The entire high-level implementation of the model is contained in whisper.h and whisper.cpp. The rest of the code is part of the ggml machine learning library. The command downloads the base.en model converted to custom ggml format and runs the inference on all .wav samples in the folder samples. whisper.cpp supports integer quantization of the Whisper ggml models. Quantized models require less memory and disk space and depending on the hardware can be processed more efficiently.

Features

  • Plain C/C++ implementation without dependencies
  • Apple silicon first-class citizen - optimized via Arm Neon and Accelerate framework
  • AVX intrinsics support for x86 architectures
  • VSX intrinsics support for POWER architectures
  • Mixed F16 / F32 precision
  • Low memory usage (Flash Attention)
  • Zero memory allocations at runtime
  • Runs on the CPU
  • C-style API
