Siri makes me unlock my iPhone before sending a text message using voice

Out of absolutely nowhere yesterday, Siri started telling me to unlock my iPhone before I could dictate a text message. I have no idea why this is suddenly required and I have googled it and looked on the message boards and I find no solution. This makes using air buds and an iPhone in freezing cold weather totally useless… It was extremely efficient to be able to reply to or send a text message using my voice and now I'm unable to do it without getting my phone out of my pocket taking off my gloves and unlocking the phone. It won't even allow me to reply to a message. Again it requires me to unlock my iPhone.

I have been dictating text messages this way for years and out of nowhere this has changed. I'm very tired of all these love with the iOS updates. Is anybody else having this problem and have you figured out how to resolve it.
