Since the update to iOS 17 the voice dictation on my iPad 6th gen is very slow. It lags several sentences behind and even when I tap the microphone icon to stop it, it needs another five to ten seconds to finish the text. The longer the text, the longer the time to finish the text. All was fine before the update. Have you experienced the same?
Apologies, I misread that. I don’t have this issue on my iPad running 17.0.1. Neither in English, German, nor Spanish. Dictation is pretty quick for all three languages. It is a really strange issue to only happen in one language. I have no idea what you could try to fix this other than resetting the iPad.
I also experience a slight lag while typing on my iPhone. It was definitely smoother before the upgrade. Dictation is normal on the iPhone, though. When I switch to English everything is fine. I guess it has something to do with the new auto correction, although this is said not to be active for German, yet. The voice dictation lag is also there for French. Only English is quick and smooth.
