Siri has impressive comprehension but isn’t always perfect, and sometimes Siri can just misunderstand something or have a hard time with the spelling of certain words and names. If you find that Siri has made a mistake understanding what you’ve said, or if you just want to correct or change the question or command you asked of Siri, you can do that easily by editing the query text directly at the Siri screen:
After issuing Siri a command or asking a question, tap and hold on your portion of the dialog
Use the standard iOS keyboard to modify the query, then tap “Done” to ask Siri with the modification in place
You can modify the query text to whatever you want, but it’s really most appropriate for when a misunderstanding has taken place. The example below demonstrates adjusting the text on a weather inquiry:
After a modification is made, Siri will return a response based on the adjustment.
This works with quite literally any Siri dialog or question, you can get some ideas from the giant list of Siri commands that you can get from Siri just by asking “What can you do?”
By the way, if Siri frequently messes up the understanding of contact names or businesses, adding phonetic spelling to the address book entry will usually resolve those issues and prevent you from having to ask repeatedly or edit the text.
