How do you get the lady on the iPhone to stop talking?

To stop the voice assistant on your iphone, you can simply say "Hey Siri, stop" or press and hold the side button (or home button on older models) to activate Siri and then ask her to stop speaking. Alternatively, you can adjust Siri's settings by going to Settings > Siri & Search and turning off "Voice Feedback" to minimize verbal responses. If you want to disable Siri altogether, you can turn off the feature in the same menu.
