Siri doesn't speak but only writes to my questions. What is wrong?

Hi zey007,

Thanks for the post. I see you have an issue with Siri and with audio on calls.

For the Siri issue, start with this resource: If Siri or "Hey Siri" isn't working

"If Siri doesn't speak responses

Siri might not respond verbally if your device is muted or Voice Feedback is turned off. While you're on the Siri screen, try to increase the volume level on your device. Then check your Voice Feedback settings:

• On your iPhone, iPad, or iPod touch, go to Settings > Siri & Search > Voice Feedback. From here, you can change how Siri responds. For example, you can have Siri always respond or only when you're using the Hands-Free setting."

To troubleshoot the microphone/call audio issue, I recommend this link: If the microphones on your iPhone, iPad, and iPod touch aren't working

If you complete all of the troubleshooting in the links above and the issues persist, I suggest getting in touch with Apple: Contact Apple Support

Have a great day.
