AOS - MuDeok's thinking voice is Go Yoon Jung's voice, not JSM

I repeatedly watched episode 1 to confirm if it really is the original Naksu's voice inside MuDeok's head.

IT IS!!!!  

Honestly, they sound too similar for you to be this sure. JSM are claiming its her voice and GYJ's fans are also claiming its her. So who knows

I also thought it's yoon jung's voice. But in the last episode I thought it's So Min's. I don't know I'm confused.

 AncientLoveGoddess:

I agree that it is GYJ voice but as you can see, they are so similar that most people cannot tell them apart so it honestly doesn’t matter that it’s her voice since nobody can recognize the difference.  

yeah you're right. 

It is Yoon Jung's voice because she is  given credits at the end when her voice is used. 

yes most of mudeok inner voice is gyj's  but early ep i remember i heard jsm's
for example when shes under the blanket in janguk's room. thats clearly jsm's

After using my headphone for the voice over - it is 100% GYJ's voice.

Episode 1.- 29:18 when Mudeok was given chicken to eat by the man that was selling her and she said in her head about not eating chicken. That was So min’s voice,At 30:20 again thinking voice at the brothel when the man was leaving her there that was So mins voice( thinking voice)

Listen closely to so min talking voice when she first speaks to Maidservant Kim, she then is seen outside thinking whilst walking it’s the same voice  100%.

When she imagined doing the spell on Uk in the bathhouse ( the tornado spell) and Uk caught her smiling ( that was GYj, not just because she actually did that scene) but so min and GYj have different undertones, So-Min did an amazing job of trying to get her tone to match but if you listen closely to both actresses you can hear the difference in their undertones . If you listen without thinking about who is talking ( without looking) you can hear the difference the the tones from both actresses 

In episode 10 for example all the thinking voice as far as I remember is GYJ ( listen for example at 1:11:37 when Uk was telling her about the love letter and she thought( I should’ve braced myself before letting someone get this close) you can hear  a very clear difference in Mudeok’s actual speaking voice to thinking voice. Do the same with episode 1 and notice that Mudeok’s (so-Min’s) actual voice carries a specific undertone that matches with her thinking voice in some scenes. It’s also best not to listen with headphones, listen without looking at the screen. It tends to be clearer then And stat at The very first scene of Naksu introducing herself ( listen for her undertones)?
