Yes — Apple introduced a new Speech Analyzer API for speech to text, along with a new SpeechTranscriber model that’s faster and more flexible than the previous generation model.
A few important notes:
- It’s for speech-to-text, not text-to-speech.
- It runs on device and is designed for things like long-form audio, meetings, conversations, and live transcription.
- Apple mentioned it in the session Bring advanced speech-to-text to your app with SpeechAnalyzer.
If you meant higher quality text-to-speech, I don’t see an API for that in the provided WWDC context. The closest related update here is the new speech-to-text stack, plus Siri voice and dictation improvements mentioned in the keynote.
