Does the iOS Speech API support grammar?
问题 I was investigating various Speech Recognition strategies and I liked the idea of grammars as defined in the Web Speech spec. It seems that if you can tell the speech recognition service that you expect “Yes” or “No”, the service could more reliably recognize a “Yes” as “Yes”, “No” as `No”, and hopefully also be able to say “it didn’t sound like either of those!”. However, in SFSpeechRecognitionRequest, I only see taskHint with values from SFSpeechRecognitionTaskHint of confirmation ,
