Siri has lost her mind on voice to text

In the last two-three days, when I try to do voice to text, Siri goes nutso. If the text is too long, she goes off on a tangent about how long my "question" is and can I ask it in a more simple fashion? This doesn't happen if the text is brief. This is a recent problem - prior to this, I could dictate very long texts, and other than a few problems in translation, Siri had no problem with it. Anyone else experiencing this?
