No, that doesn't seem to be the case.

You may not notice if the call was answered automatically and you didn't have your device on you, and the call could be forwarded with acceptable latency so the speech wouldn't be in earshot. Or these days you could use an AI to generate voice and it would sound realistic.

Just because something isn't likely to affect ordinary citizens doesn't mean it isn't possible.
