How to Record Siri's voice with Screen Recorder?

Hello!

I am attempting to record siri's voice when I ask a question or her response while using the internal screen recording control from the control center.

For some reason while using the screen recorder, if I highlight the text and ask it to speak it, the samantha voice will read it out, but it does not sound like siri at all.

Yet if I use the screen recorder, talk to siri ask her a message her voice does not appear. I have tried this with both the 'microphone' on and off and it does not work. Do you guys have any solutions to this problem?
