Hey there! As someone who's tinkered with Apple's speech recognition APIs, I can give you a straight answer to your question:

Yes, SFSpeechRecognizer in iOS 15 and later fully supports speech recognition for audio clips longer than 1 minute.

Let me add some context to help you grasp the change:

• Before iOS 15, there was a strict 1-minute limit when using SFSpeechURLRecognitionRequest (for pre-recorded audio files). If you tried to process anything longer, the request would fail immediately.
• Apple lifted this restriction starting with iOS 15. Now, you can use SFSpeechURLRecognitionRequest to handle audio files of nearly any length, and real-time recognition (via SFSpeechAudioBufferRecognitionRequest) also works for extended recording sessions without hitting that old cutoff.

A few quick tips to keep in mind as you build this out:

• Don't skip adding the NSSpeechRecognitionUsageDescription key to your Info.plist – include a clear message explaining why your app needs speech recognition access, since Apple enforces this privacy rule strictly.
• For extra-long audio files, consider adding progress indicators or accounting for potential network delays (most speech recognition relies on Apple's cloud services, though on-device options exist for select languages).
• Always test on a physical iOS device instead of the simulator, as speech recognition functionality is severely limited in the simulator environment.
