I have an iPhone 6 running iOS 9 – Siri has become speechless all of a sudden. It appears to have went dumb; there is no voice feedback whatsoever.

Siri answers all of my questions correctly with an on-screen response, but there is no voice feedback at all. Can this be sorted without a restore?

PS: I have already performed a Soft Reset.

Voice feedback can be enabled/disabled in Settings -> General -> Siri.

  • It's enabled, else Siri just won't turn up. Mine is working fine but not speaking.

  • You can not only enable Siri there, but also the voice feedback (second to last option on the page).

This issue (essentially a "silent Siri") appears to be prevalent with many iPhone 6 devices running iOS 9. Which language are you currently using Siri with?

A full restore of the iPhone may not be necessary. First, invoke Siri and ensure the volume is turned up.

Next, please can you attempt resetting the Network Settings first, by visiting:

Settings > General > Reset > Reset Network Settings

Please attempt to invoke Siri after resetting the Network Settings. If this does not solve your issue, you may need to reset all device settings (your apps and data will remain unaffected).

To reset all device settings, please visit:

Settings > General > Reset > Reset All Settings

Unfortunately, if these minor resets are unable to alleviate the issue, I would advise a full restore of your iPhone, as this appears to be the sole remaining solution.


I recently had this issue (which wasn't fixed through general troubleshooting) and fixed it by changing to a different voice.

"Settings", "Siri & Search", "Siri Voice".

UPDATE: The voice switched back to the previous voice on its own, and it is now working. 🤔

I prefer the previous voice, but I'm assuming it is corrupted somehow. There doesn't seem to be a way to delete and reinstall the voice (without a full restore). I'm optimistic that a new iOS update will eventually fix the voice automatically, so I can switch back to that voice.
