Apple's new SpeechAnalyzer API has been benchmarked against Whisper and its predecessor, SFSpeechRecognizer, on a standard test dataset of 5,559 utterances. The results show that SpeechAnalyzer is the most accurate on-device speech engine, beating Whisper Small and SFSpeechRecognizer on both clean and noisy speech. SpeechAnalyzer also runs roughly three times faster than Whisper Small. The benchmark suggests that developers should migrate from SFSpeechRecognizer to SpeechAnalyzer for improved accuracy.
