%description
High-performance inference of OpenAI's Whisper automatic speech
recognition (ASR) model:

* Plain C/C++ implementation without dependencies
* Apple Silicon first-class citizen - optimized via ARM NEON,
  Accelerate framework, Metal and Core ML
* AVX intrinsics support for x86 architectures
* VSX intrinsics support for POWER architectures
* Mixed F16 / F32 precision
* 4-bit and 5-bit integer quantization support
* Zero memory allocations at runtime
* Support for CPU-only inference
* Efficient GPU support for NVIDIA
* Partial OpenCL GPU support via CLBlast
* OpenVINO Support
* C-style API
