Hi Binxy1985,
We'd like to help you find the best solution for helping with Siri. We would recommend with starting with Restart your iPhone. If this continues, another option for isolating this issue is to see if this is specific to your device or the adapter. We would recommend connecting to another device and see if this remains, and if it does, you'll want to reach out to Apple Support. You can use the link below, if needed.

If this is specific to the device, we would like to know what Siri settings you have off, such as "Hey Siri". Let us know further.
Thank you for using Apple Support Communities.
