Chapter 583: Found You!

That night, the two old men nearly fought over who lived in Nanming, but later, old man Lu got the better of him and snatched Nanming away.

Early the next morning, as soon as Nan Ming opened his eyes, he saw Chen Wei standing happily in front of him, staring at the two bloodshot panda eyes and saying: "We caught him, we caught him!"

"Caught it?" Nan Ming smiled, "I'm almost caught too!"

When Nan Ming said that he was about to be caught, he was referring to "killing Ming".

If Chen Wei hadn't encountered such a case deliberately used to make things difficult for him, I'm afraid Nan Ming would never have thought that voice and recording could be used in this way.

"Killing Ming" was too careful, Nan Ming couldn't track her through Xiaobai, but Chen Wei gave Nan Ming an alternative plan.

In modern society, unless you hide in the mountains, no one can completely escape from the camera. If you can know a person's appearance, it will be much easier to find him.

At least for Nan Ming who has a "slacker".

However, there are no easy things in this world, and Nan Ming still faces three problems.

The first problem is that this "killer" may have used computer voice software, but Xiaobai did not calculate a fixed basic language pattern after analyzing all the calls, which means that this call was not recorded through splicing Generated, but the electronic sound also has an analog sound mode, and we are trying to rule out this possibility.

The second problem is that even if the voice is not synthesized by a computer, it is possible to use voice-changing software. Shaming on the phone is a mature female voice, but the real Shaming may be any kind of voice, men, women, old people and Child. Xiaobai calculated the distortion of the sound, and concluded that the sound was compiled by an algorithm.

The third problem is that Shaming may be of any race. There are many kinds of races in the world, and the features of the skulls of each race are different. The final calculated appearance will also have certain differences. For Chen The model established by Wei defaults to male Han nationality, which is the most likely possibility. The result is of course gratifying, but other possibilities cannot be ruled out.

But even if faced with three problems, at least there is a solution!

Under Nanming's order, now Lazy and Xiaobai have started to search for videos of various races on Youtube to obtain more voice and facial model information.

To obtain a more accurate model, I am afraid that it is necessary to traverse the entire Internet and retrieve nearly ten million corresponding data. This is a huge amount of work, and it is genuine big data. It is not like last time, which can be done in a few hours.

But what Nan Ming has to do now is to solve the problem of voice changing software first.

If you want to restore the distorted sound, you must find a reference object. During the call, there were some noises. Nan Ming asked Xiaobai to separate each of the noises and make a separate audio track, and then combined with other noises. Compare various recording effects to find possible corresponding sounds.

I was busy in the middle of the night yesterday, today Chen Wei is not in a hurry to go to work, and is helping Nanming as a staff officer.

Chen Wei paid more attention to this person clamoring to kill Nan Ming than anyone else, and he wished to catch him all at once, just like the scum in the police before.

So even though he was really busy recently, he still did enough homework.

"In terms of probability, since the other party has a relationship with Debitz, there is a high probability that the environment in which it is located will also be related to Debitz. Debitz is a non-listed private company headquartered in Luxembourg. The major shareholders are: Anglo American plc, the Oppenheim family and the Botswana government account for 45%, 40% and 15% of the shares respectively. Since Anglo American plc, the Oppenheim family, or the Botswana government are all South African and Neighboring countries, so I think this person is very likely to be in South Africa. If this person is in South Africa, then these noises are probably compiled by sound software that is common in the streets and alleys of South Africa."

"That is to say, I just need to focus the audio search on the videos uploaded by South African users, and then intercept the noise for comparison..." Nan Ming's eyes sparkled.

"I think there is actually a better way." Chen Wei said, "In terms of abstract thinking and distortion analysis, the human brain still has unique advantages. I think it is better to find some experts who know South Africa very well and ask them to listen to these What is the sound."

This is Chen Wei's most valuable suggestion. Nanming sometimes believes too much in technology, and forgets that human beings are one of the greatest creations of nature. At present, there is no technology that can completely replace human capabilities.

Nan Ming didn't stay in bed anymore, he got up and ran to arrange this matter.

"You're finally awake, kid. I bought you some breakfast. It's almost cold. Come and have a look. These breakfasts..." Mr. Lu was doing Tai Chi in the yard when he saw Nan Ming shouted, but Nan Ming It disappeared in a flash, leaving Lu Lao shaking his head helplessly: "This little monkey!"

When you are lazy, you are lazy, and when you are diligent, you are too diligent.

Thinking of finding someone, the first person Nan Ming looked for was Qing Zhongtang. Hearing Nan Ming's needs, Qing Zhongtang patted his chest and said to him. In a conference room.

"Mr. Nan, these are colleagues in our system who have worked in South Africa for a long time, as well as some colleagues on the diplomatic front." Qing Zhongtang said, "I have already explained the general situation to them. Mr. Nan, you can directly release the audio , let them listen to it."

Qing Zhongtang found twenty or thirty people for Nan Ming, and they gathered together, including men, women and children.

Listening to the recording played by Nan Ming, these people frowned and shook their heads frequently.

Looking at their expressions, Nan Ming was inevitably disappointed.

At this moment, an old diplomat with gray hair said, "Mr. Nan, why don't you play the original audio for us to listen to?"

Nan Ming was a little embarrassed, Qing Zhongtang nodded to him, basically those who could be brought here by Qing Zhongtang were relatively reliable, because of work reasons, they knew how to keep secrets.

Nanming released the dialogue between himself and "Shaming", and everyone listened with frowns. The dialogue was a bit weird, such as the Great Demon King of Nanming, which sounded very secondary.

However, releasing it in this way has really achieved results. The ability of the human brain to comprehensively process information is still far superior to all machines. The old diplomat just now hummed suddenly. It sounded like a simple melody. He said: " Mr. Nan, I think this should be a South African folk song, a little distorted, and the musical instrument is a small gadget in South Africa, called... what is it called?"

"Thumb Piano!"

"Xiaobai, search for a musical instrument called a thumb piano, read its timbre, and then search for African folk songs, and compare them..." Nan Ming said.

On the screen behind Nan Ming, the spectrum of the conversation with Sha Ming was gradually changing. When the spectrum finally settled down, a very young female voice sounded: "I'm sorry, for the future of the universe, I have to kill you!"

"I'm sorry, I found you!" Nan Ming smiled.

The second problem has been solved!

(Well, because Chen Wei was blocked for some reason, so I changed my name to Chen Wei.) (To be continued.)
