[0:05] Hey all, Marty and Michael here. Today we’re going to show you voice isolation.
This is a new feature that was released in this previous update that just came out a couple of days ago.
And what it is, is if you have a lot of noise around you and you need to really get better audio out of your microphone, this will block out the sounds around you such as outdoor sounds like if a fire engine goes by or if there’s a lot of traffic anything like that.
So Michael is going to show you how to enable this and Michael take it away.

[0:44] Full transparency initially I was going to bring my phone into the recording but well I kind of lost my adapter so I’m going to walk you through the process of enabling voice isolation on iOS 16.4 while on a phone call.
Out by making a phone call. So what we’ll do is we’ll start by telling Siri to call someone real quick.
Call 458-666-3342. Calling plus one 458-666-3342.
This will now call a number and the phone is on like I’m making a phone call to someone. Now if I take the phone away from my head, you’ll be switched over to speaker.

[1:29] So what I need you to do is find the time in the top left corner of your screen.
Three finger flick up and you’ll hear that you’re in your control center.
If you explore the screen you’ll see something that says Video Effects towards the top of the screen. If you slide your finger to the right it’ll say Off.

[1:47] Continuing your finger to the right will say Selected Phone.
And if you slide your finger or flick to the right again you’ll hear Standard.
If you double tap on Standard this says Selected Standard button.
And then you can flick to the right and there’s an option that says voice isolation button. Double tap on voice isolation button and this will then be selected.
Wide spectrum, as of the time of recording, is not available on actual phone calls. So, though it shows, you can’t actually enable it.
Do a scrub gesture. This is two fingers sliding fluidly from the right back to the left and then to the right again.
Or use your single finger and swipe up from the bottom to do a home gesture.
Press your home button if you have an SE and this will take you back to your control center. Do this again to get back to the in-call screen and now people can hear you a lot more clearly on their phone.
Quick note, it appears that you do have to re-enable this every phone call that you want to use it on. We hope you found today’s demonstration to be helpful.
