automatic speech recognition by argmaxinc

whisperkit-coreml

WhisperKit CoreML is a collection of Whisper speech recognition models exported to Apple's CoreML format by Argmax, enabling on-device ASR on Apple Silicon (iPhone, iPad, Mac) without network calls. The models run via the WhisperKit framework, which handles chunking, VAD, and decoding on-device. Designed for iOS/macOS applications requiring offline transcription.

Use cases

  • On-device transcription for iOS/macOS apps without server-side ASR
  • Privacy-preserving voice note transcription on Apple hardware
  • Real-time caption generation in macOS applications
  • Offline speech recognition in regions with unreliable connectivity
  • Integrating ASR into Swift/Objective-C apps via the WhisperKit framework

Pros

  • Runs entirely on-device — no network dependency or API cost
  • Leverages Apple Silicon Neural Engine for efficient inference
  • Multiple model sizes available (tiny through large) for different device capability levels
  • Privacy-preserving by design — audio never leaves the device

Cons

  • Apple platform only — no cross-platform use
  • Requires WhisperKit framework integration in the host application
  • Accuracy constrained by CoreML quantization vs. server-side full-precision Whisper
  • Older or non-Apple Silicon devices see reduced performance
  • Model downloads are bundled with the app or downloaded at first use — adds app size
