I just bought this phone off of someone how do I get it to where I can reset Siri so she can recognize my voice

Hi post23,

Congratulations on your new iPhone! We see that you'd like assistance with getting Siri to recognize your voice. We're happy to help.

Siri should respond when activated and doesn't need to be trained to recognize your voice. Take a look at the following resource for a few ways to talk to Siri: Ask Siri on iPhone

If you're experiencing an issue using Siri, please follow the steps here: If "Hey Siri" isn't working on your iPhone or iPad

Thanks for using Apple Support Communities.
