When passing by the third floor, Li Weiguo and Luo Kai also stretched out their heads to take a look inside, wanting to see what the new project in Wu Hao's mouth was.

But Wu Hao chose to ignore this and continued to guide everyone to the fourth floor. There is nothing mysterious about the third floor, as he said, there is only one cluster technology research team inside.

The main reason why they didn't want to visit was that there was a lot of information about their new project. Li Weiguo and Luo Kai are both old foxes, and Wu Hao doesn't want them to find suspicions during the visit.

The project is still being studied, and he doesn't want it to be leaked until it is available, especially since the Air Force Equipment Research Institute, which has mastered their swarm control technology.

In case it is really borrowed by them, then who will he talk to.

When they came to the fourth floor, everyone's vision widened. The entire fourth floor is very transparent, all areas are separated by glass, and the indoor greening is in place, and the whole office environment can be said to be very superior.

At the moment, the researchers are busy, and Wu Hao's arrival has not been affected much. Many people just look up and then get back to work.

Wu Hao said to everyone: "This is our scientific research area on the entire fourth floor, and the main work is currently engaged in the follow-up development of intelligent voice assistants."

The whole office area is fan-shaped, in addition to the work and development area by the window, there is also a small conference hall, rest area, and the one inside is a comprehensive test area.

At present, we are not working on many projects, and the main thing is to optimize the problems existing in this intelligent voice system.

For example, in terms of regional accents, dialects, and the perception of emotions, especially subtle and intense emotions, this needs to be optimized to make it more fully aware of the user's state at the time. ”

Hearing this, Qian Jianyuan nodded and said, "I'm very interested in your emotions and language perception, can you tell us more?" ”

"Of course, you guys, please."

Wu Hao took everyone to the comprehensive test area, and then opened the large LCD screen on the wall and introduced: "In fact, it is still difficult to perceive people's emotions by sound alone, although we have done a good job in this area, but it is still not enough."

So we decided to use the method of detecting heart rate to sense people's emotions in various environments, which is why we chose wearable speakers instead of traditional smart speakers.

As we all know, people have different heart rates under different emotions. Combined with a series of factors such as the content of the speech at that time, the tone, the tone of voice, and the breathing, you can judge the mood of the person at that time. And through emotions, we can also infer the tone and meaning of the user's speech at that time. ”

"And how do you make the voice of the device emotional, or how do you simulate the voice of a real person?" Qian Jianyuan nodded, and then asked.

Hearing this, Wu Hao then opened a schematic diagram and said: "This is actually simple, since we can already perceive people's accurate emotions, tone, context and specific meanings. Then we can extract this part of the data and experience it, and then put it into the intelligent speech system and link it with the corresponding vocabulary sentences.

When the system determines what needs to be said, the program automatically selects the appropriate tone for the content.

The more you perceive, the more you learn. As a result, there are more and more tone templates to choose from, so the simulated human voice becomes more and more realistic. ”

"It's that simple, I'm afraid it won't be so easy in real time. Can I take a look at the core structure of this intelligent voice system, your secrecy is too strong, and we have tried a lot of ways to crack it. Qian Jianyuan said frankly at him.

Indeed, it is not a glorious thing to study other people's techniques in private. But I'm afraid that at this moment, many laboratories around the world are probably thinking about his intelligent voice assistant.

So Wu Hao was not surprised when he heard this, after nodding slightly, he tapped on the keyboard for a while, and then a three-dimensional node diagram appeared on the big screen.

The whole diagram is made up of staggered lines connecting different nodes, and then these nodes are combined into a giant node. The huge nodes are connected to each other and diverge, thus forming this huge three-dimensional network.

It's not so much a solid node as it is a solid geometry, and this diagram looks like it wants to say a regular solid geometry.

Seeing this, Qian Jianyuan immediately took the reading glasses from the assistant's hand and put them on, and then leaned over to the big screen and began to check them carefully. And Li Weiguo, Luo Kai and the others also gathered behind them and looked at them carefully.

After staring at it for about five or six minutes, Qian Jianyuan suddenly became excited, and danced at Wu Hao: "You, you, you actually used a neural network structure to build the entire core, no wonder."

I see, this includes BP neural network algorithms, fuzzy neural network algorithms, K-means clustering algorithms, and deep learning technology ......"

Listening to Qian Jianyuan reading those obscure terms there, those who understand a little bit are fine, but those like Li Weiguo who don't know much are a little confused.

However, judging from Qian Jianyuan's excited expression, this is definitely a major technology, otherwise it would be impossible to make the young Qian Lao so excited.

"Genius, absolute genius. After this thing is published, it will definitely make a sensation in the world. Qian Jianyuan looked at him with a glint in his eyes, and this feeling was like a greedy landlord seeing a piece of gold.

Wu Hao smiled when he heard this: "No, I'm not that great. So you and everyone can just take a look at this thing today, don't spread it, I don't want to cause too much trouble. ”

"You, what can you tell me to say?" When Qian Jianyuan heard his words, his eyes widened, and he didn't know what to say. Suddenly, when he saw the person following him secretly filming with a mobile phone, he couldn't help it anymore, stepped forward and snatched the mobile phone and scolded: "Who asked you to shoot, can this thing be filmed, there are no rules at all, have you forgotten the confidentiality regulations you learned before."

Who else filmed, delete it all for me, now, right away! ”

Seeing that Qian Lao was angry, Li Weiguo on the side also had an ugly face and said: "Give all your mobile phones and camera recording equipment to my secretary for safekeeping, and he will investigate them one by one." If anyone shoots it, delete it immediately, which is the least respect for the comrades who trust us.

When you go back today, all of you will copy the rules and regulations of secrecy, each of you ten times! ”
