#SpeechAnalyzer

Apple introduced the new SpeechAnalyzer API at WWDC25 for on-device speech-to-text. A benchmark article compared its performance to OpenAI&\x27;s Whisper and Apple&\x27;s predecessor, showing competitive speed and accuracy. This API could disrupt existing ASR wrapper apps by providing a native, high-quality solution integrated into macOS/iOS, potentially making third-party transcription services less necessary. The benchmark tested on math lectures; SpeechAnalyzer was substantially faster than Whisper-Large-V2 and only slightly worse in accuracy. It runs entirely on-device, preserving user privacy.
