Hi RebekkahRoseRyan,
Re: "Siri : will not respond with voice, only with typed text on my phone screen."
Seems there may be a Siri setting on your iPhone that needs changing.
Go to Settings > Accessibility > Siri > choose "Always Speak Responses"
If needed:
Here's a link to Apple Support's article:

If you find you still need to turn off screen responses:
Go to Settings > Siri & Search > Tap Siri Responses > then choose an option below Spoken Responses.
Eg: You can turn off: "Always Show Siri Captions" if it is on
or
You can turn off: "Always Show Speech" if it is on
If needed:
