The folks over at OSXDaily have put up a handy step-by-step tutorial on how to enable Siri’s muting & unmuting with the hardware mute switch on an iPhone or iPad. This way, you can continue to use Siri for commands and queries, while silencing the virtual assistant’s default voice feedback response. Here’s what you need to do:
Open Settings and Go to General > Siri.
Choose Voice Feedback and select Control with Ring Switch. The mute switch on the side of the iPhone and iPad is referred to as the “Ring Switch” here.
Leave Settings and activate Siri with the mute switch enabled. Siri will now respond in text and on screen only.
That’s it, enjoy!
