Is it possible to make completly 'mute' NPC?

[LFact]

Currently, I'm learning how to use CS. During making companion NPCs for CM Companion, I wondered if it's possible to make 'mute' NPC whose race is from vanilla game. I mean:

There's a random NPC lives in Cyrodiil. Since that NPC is mute, he/she cannot speak(though we can assume he/she can communicate others with writing or hand sign) at all.

Though I'm looking for the possibility, I don't know if it can be done because I'm a newbie at modding. So, can someone tell me how to, please?

You would have to setup dialogues that point to that specific NPC that are linked to a silent mp3. This is much easier done if you have a new race (just a copy) setup for this NPC. You would still have to setup all the normal dialogues no matter what you did.
