How do make a voice memo into an alarm

Hello Ruth2014,

Thank you for taking the time to post your question using Apple Support Communities. We understand that you'd like to assign a voice memo as an alarm tone on your device. We're happy to provide available options.

First, the recording would need to be made into a tone using GarageBand or Logic Pro: Create a ringtone of your Logic Pro or GarageBand for Mac song

Once this is complete, and you've shared it to your device, you can assign it as an alarm sound. How to set and manage alarms on your iPhone

If you have additional feedback about the process to share with Apple check out this link: Product Feedback

For any additional question about GarageBand or Logic Pro, contact Apple Support here: Get Support

Cheers!
