Resemble.ai (mentioned on our stream by our software consultant) is one of the top voice synthesizers on the market right now.
They have open sourced Resemblyzer, a deep learning package to analyze and compare voices.
Part of Resemblyzer is fake speech detection code.
This is their demo on real and fake Donald Trump speeches. It compares test audio against ground truth reference audio. As you can see, there is one false positive.
I downloaded Resemblyzer and ran it on the audio of the IG videos. I used as ground truth ZZH's interviews and audio from before Aug. I used as control the LXZ interview, cut into ~1 min clips. For the latest IG video, I cut out the singing part.
When they turned on the TV screen, ZZH raised his eyebrows and gave GJ a look that clearly said: See? I was right.
GJ looked at the TV then looked at him, stumbling over his words, "It's just-- it's because--"
He floundered, before finally giving up, "So what?"
He contended, a little petulantly, "You're my senior, what am I supposed to call you?"
ZZH didn't force the issue, he just thought it was funny. He patted GJ's arm and soothed, "It doesn't matter, you can call me whatever you want, anything you like, it's all fine with me."
GJ walked into the room to see ZZH holding a thermos in both hands, blowing on it. His hair stood up fuzzy and soft, and GJ had an sudden urge to pull him into his arms and rub at it.
"You're here," ZZH greeted him cheerfully, then asked, "Did you not get enough sleep?"
GJ shook his head and took a bottle of water out of the fridge to put over his eyes, sitting beside him on the bed, "How come you're up so early?"
ZZH continued to blow on the thermos, "Young man, early to bed and early to rise are healthy habits, understand?"
(Translator notes: The beginning of this chapter is a flashback to events that took place just before Chapter 4, then it jumps to after Ch4 and the 5th time they end up in the Room.)
GJ was playing HOK when ZZH called him. The incoming call successfully interrupted his positioning and a curse was on the tip of GJ's tongue before he saw the caller ID and choked it back. His heartrate instantly made an exponential jump.
When ZZH walked into the room, GJ didn't acknowledge him as usual. He was looking at something on his phone. ZZH walked over and he still didn't look up, intently scrolling on his phone.
ZZH didn't see what was on his screen and felt a little put out as he walked to the mini fridge and took out a Coke. He thought, there's no signal, what's there to look at, do you just not want to talk to me?
