Modifying a Siri message

Hey slscheffer,

Thanks for using Apple Support Communities! I use Siri to message my friends and family all the time, so I definitely understand wanting to know all your options about making changes to a message before sending it.

You can definitely change a message before sending by just saying "Change it." Siri will then prompt you say new/changed message. You can see more about using Siri here: Ask Siri on iPhone

I hope that helps answer your question about Siri! Cheers!

Further, you can tap the message as it is displayed on the screen and type more into it or you can tell Siri "Add to it" and then whatever you say from that point will be added to the end of the already spoken/typed message
