Whisper Models and Local Transcription Benchmarks
Compare local speech recognition models by speed, accuracy, language coverage, and Apple Silicon performance.
Every local speech model we ship or have benchmarked — what each is good at, how fast it runs on Apple Silicon, and which one to pick for your language. All numbers below come from our published benchmark articles.
Local Speech Models at a Glance (2026)
The short version: on a Mac, use Parakeet V3 for English and European languages (it's the default in Whisper Notes), SenseVoice for Chinese, Japanese, Korean, and Cantonese, and Whisper Large-v3 Turbo for everything else in its ~100-language long tail.
| Model | Best for | Accuracy | Speed on Apple Silicon | Languages | In Whisper Notes |
|---|---|---|---|---|---|
| Parakeet V3 (NVIDIA, 0.6B) | English & European languages | 6.32% English WER (our FLEURS test) | ~10× faster than Whisper Turbo | 25 | Yes — default on Mac |
| Whisper Large-v3 Turbo (OpenAI, 809M) | Widest language coverage | 7.83% English WER (our FLEURS test) | ~5× faster than Large V3 | ~100 | Yes — optional download (~1.6 GB) |
| SenseVoice Small (FunAudioLLM) | Chinese, Japanese, Korean, Cantonese | Purpose-built for CJK | 27-min Chinese podcast in 13.83 s (M4 Pro) | CJK focus | Yes — since v1.5.0 |
| Whisper Large V3 (OpenAI, 1.55B) | Reference baseline | Near-identical to Turbo | Baseline (slowest here) | ~100 | No — Turbo supersedes it |
| Voxtral (Mistral) | Speech + language understanding | See our benchmark article | Server-class models | Multilingual | No — covered in blog |
WER = word error rate; lower is better. Our numbers: FLEURS benchmark plus in-house tests on an M4 Pro running Whisper Notes — full methodology in the linked benchmark articles below. All models listed as "in Whisper Notes" are included in the one-time price.
