How to Create Custom Siri Audio Introductions

Tired of the mundane “beep” that Siri does when you initially invoke her? Maybe you found our tutorial on how to make Siri say “Yes?” compelling?

If that wasn’t enough for you, then you can take it a step further and create your own custom Siri audio introduction as well. Check inside for our full tutorial…


Step 1: Create a custom 1-2 second audio file and name it jbl_begin with a .caf extension. See our video for more details.

Step 2: SSH into your device, and venture to the System/Library/Audio/UISounds/ directory, and rename the jbl_begin.caf file to jbl_begin.caf.old to save it off.

Step 3: Copy your custom jbl_begin.caf file to the System/Library/Audio/UISounds/ directory, then invoke Siri to test out the change. You should hear your custom sound instead of the standard Siri beep.

Notes: In this tutorial I used QuickTime and iTunes to create my custom jbl_begin.caf file. There are other methods to doing so such as GarageBand, and I’m sure there are Windows methods as well. I only took this so far, but as you can probably tell, it’s up to you how far you want to take this.

There will undoubtedly be a jailbreak tweak in the future that will allow you to record and create your own custom Siri intro sounds right on the device, but for now, this is a fairly easy to follow workaround. What do you think?
