Apple's SpeechAnalyzer Beats Whisper Small in Accuracy and Speed
Apple's new SpeechAnalyzer cuts word error rate to 2.12% on clean LibriSpeech, four times better than the legacy SFSpeechRecognizer and outperforms Whisper Small on both accuracy and speed, running about three times faster on an M2 Pro. The result makes it the best on‑device English recognizer for Apple hardware.
