I can second this. I am nearing launch on an app that uses both the new SpeechAnalyzer and on device LLM and it has met or exceeded my expectations. A longer context would always be nice but then I remember its running on a phone.
Thanks for the follow-on anecdote. I'd be happy to try out your app. Please email me when it is available: [email protected].
Are you using to for speech-to-text/text-to-speech? I have been using SpeechRecognizer & SpeechSynthesizer and they have been pretty underwhelming.
