With iOS 7.1, Siri does not understand the phrase "All Caps" and furthermore, the voice-to-text feature (is that considered Siri?) will not transcribe that phrase in Messages and Mail. This is not a transcription error; rather, she simply ignores that particular phrase. However, the word "All" and the word "Caps" are recognized when they are uttered individually. Is this a bug or is there some other reason the phrase "All Caps" is ignored? Are there other phrases that she doesn't understand? I am perplexed.
