Associating recording with a name

I am a beginner in FreePBX and I have a (probably) simple question. I am trying to figure this out for days and it is still a mystery to me:
How do I associate a (uploaded) recording with extension name? Example: when incoming caller gets our main IVR and types first or last name, currently FreePBX spells the names of my employees, instead of playing the recorded name of that person. Can someone help please?
Thanks a lot.

If configured correctly and if they have made a recording of their name in the voicemail system, it will read that name to them.
