The reporters on the scene have tried out the first sound of the audio, before and after only ten minutes, for the "first sound of the video and audio beta" of the function of searching for song resources by lyrics, it is already basically clear.

I have to say that in the face of similar products in the same period in China, this innovation is real.

However, it is inevitable that there will be slight flaws in the white bi, and after the common track audition, a few male reporters with strong technical nerdy attributes soon tried some cold songs, and then found that they could not be searched according to the lyrics, so they immediately raised their hands to signal.

"Mr. Gu, can I move on to the question session now? I have some technical questions that I would like you to explain. ”

Gu Mojie confidently returned with a smile: "You can ask questions casually, as long as you follow the order, we don't have any threshold here." ”

"Mr. Gu, I found that there are some relatively unpopular songs, and I can't find them using lyrics search. And I also took a few minutes to do a comparison test. If you can't search for a song with lyrics on Hatsune Audio, you can't find the lyrics when you use Qianqian Jing to listen to it - can I understand it this way, Hatsune Video and Audio plagiarized Qianqian Jing Listening in terms of lyrics matching number jù library? ”

It's a very sharp question, and at first glance, it is asked by thousands of quietly listening supporters.

Qianqian Jingting at the beginning of 05, although there is no function of searching for songs by lyrics, but the lyrics function itself has been there for a long time. Before the advent of Qianqian Jingting, domestic netizens couldn't see the lyrics when listening to music on the Internet; It is also from Qianqian Jing Listening, that the songs played on the computer have the same subtitle effect as in KTV, as well as the rhythm. It's just that the timeline of that rhythm is not very accurate.

Gu Mojie observed the reporter's appearance and expression, and the person really looked hanging. As if the whole world owed him, he couldn't wait to catch a "little brother second", so he rushed up and kicked his feet, and then shouted "You copycat".

"I don't agree with this statement, Qianqianjing listens to the tracks with lyrics, and our Hatsune video also has lyrics. But there are some Qianqianjing who don't have lyrics, and we also have them. So I think, if nothing else. Our Hatsune Video's lyrics are better than our peers - otherwise you can try this tracklist. ”

Gu Mojie said, took out a list, shook it in front of the reporters, and continued: "This table. On the computer desktop in front of you, there are also, you can open and compare and test. Some of the songs mentioned in it currently have no lyrics to display when Qianqianjing listens to them. But our Hatsune video can. And the list is only a small part, and we have not exhausted it. ”

The reporter who asked the question was silent for a moment, and the people below also tried it quickly, and it was estimated that in a minute or two, Gu Mojie's statement was confirmed.

Gu Mojie talked eloquently on stage:

"The matching of lyrics and repertoire, there is no copyright problem in this. We also just provide an open-source and shared platform. The resources of the tracks, we are not provided by us, we just help with the search. The number jù of the lyrics is compiled by our Hatsune Network and equipped with a number jù library server, and we also provide it to netizens for free. Please don't over-read into these areas.

And. In the future, we are not limited to relying on the manual maintenance of Hatsune Network employees, we have opened an open source interface, and any edited content provided by netizens, if it is aimed at the current track resources that are still blank on the lyrics matching, can be directly uploaded and reflected without manual review.

If it is a modified version submitted after being questioned twice, we will have someone to proofread and review it in the future to ensure the quality of our services.

In addition, our Hatsune Video is a comprehensive entertainment software that combines the attributes of a music player and a video player, so we have an open-source application for the 'Lyrics Matching of Audio Texts' function. It will also be used in the video field. If there are open source subtitle groups in China that are willing to provide subtitles for foreign language film resources in the future, we are also very welcome, and we will definitely match with online film and television resources to serve the majority of netizens. ”

Gu Mojie's words. A foreshadowing was laid. However, the reporters present are obviously technical nerds, and they don't know much about the business foreshadowing in the Internet business war, so no one asks questions.

At this point in the press conference, even if some people thought that Gu Mojie was a "copycat and win by quantity", now they already feel that Gu Mojie is quite sincere, and he has come up with an original work of conscience.

The press conference continued. The people from Hatsune showed a few more details of the optimization points, but they didn't cause much sensation, and finally, it was the final highlight of the whole show.

"Okay, let's take a look at one of the most important innovations of Hatsune Audio. That's why we held this press conference. ”

Gu Mojie said, the projection screen behind the podium was put away, revealing a glass-walled room behind, looking at the furnishings inside, it seemed to be a recording studio, and people who played bands would not be unfamiliar.

"I need a volunteer, if you have a friend who thinks she sings well and finds the right tune, you can try it."

There was silence for a while, and then they all raised their hands enthusiastically, and the people who were reporters were basically no problem singing a few voices.

"Okay, our ladies first, so please ask the lady on the left side of the back row to cooperate."

Gu Mojie pointed to it, which was the direction of Liu Feitong.

Liu Feitong was curious, and raised his hand just now. Gu Mojie had seen her a few times, so he naturally recognized her.

Liu Feitong ran to the stage with a little nervousness. Her image and temperament are good, and it's absolutely no problem to play a female reporter or anchor with that temperament, no one present knows anyone, and there is no suspicion.

What's more, Liu Feitong is really not a trust.

"Ladies and gentlemen, this last important feature that we're going to show you is called 'Hum Song Search'. I don't know if you've ever encountered such a situation when you're looking for a song to listen to: obviously there is a song I've heard a few times and I like it very much, but I can't name the song. At the same time, the original singer sang so vaguely that you don't even know the lyrics.

Ah, I definitely don't mean to be disrespectful to Mr. Jay Chou, but let's take some of Mr. Chou's songs as examples. For example, after listening to a song "Ninja" or "Dragon Fist", you don't hear a word, at this time, even if our Hatsune video has provided the function of 'searching songs by lyrics', you still can't find the song you want.

However, after the 'humming song search'. This qiē will no longer be a problem. As long as you remember the tune and hum it out – of course, your computer needs a plug-in microphone, and the microphone has better audio samples and a softer ambient noise when humming – then. Our software can automatically search for that song by tune! This is the most groundbreaking innovation of this edition of Hatsune Audio. Now let's demonstrate it. ”

The audience was slightly silent for a few seconds, but Gu Mojie knew that this was definitely not a cold scene, but the people below were burning their brains to digest his statement. The jump gap between this statement and reality is a bit big, and many people can't figure it out at the first time.

Immediately. There was an uproar.

"Holy! Is this all right? ”

"Really? Don't just talk about not practicing, try to show us! ”

"It's not scientific!"

Gu Mojie was very satisfied with this effect.

"Nice, quiet everyone. I know you have doubts about this, so I'm going to start the test demonstration – because you're noisy, we've prepared a professional recording studio that absorbs sound. This young lady, please follow the staff. ”

Gu Mojie waved his hand to Liu Feitong and made a gesture of invitation. Liu Feitong also heard about this function for the first time, and was a little overwhelmed, and was brought into the recording studio by the customer service lady of Hatsune Company. There is an amplifier in the studio, so you can hear what the people inside are talking and singing.

"I ...... What songs can be hummed? ”

"Whatever, since it's a test. Randomly, of course. ”

Liu Feitong thought about it, and hummed Jacky Cheung's "Kiss Goodbye" into the external microphone of the computer in the recording studio

"The past has become a cloud of smoke and dissipates in front of each other's eyes. Even after saying goodbye, I can't see that you have some grievances......"

Jacky Cheung's voice is more magnetic, and women can also sing. Liu Feitong's timbre is very beautiful, and after the broadcast of the recording equipment, everyone in the lecture hall outside can hear it. In addition, Liu Feitong's movements can be seen through the glass wall, so naturally there is no suspicion of cheating and lip-syncing.

The people who were there. No one knows why Liu Feitong chose "Kiss Goodbye", and thought it was just a whim. Only Gu Mojie and Zhou Lixin have a rough idea in their hearts: Liu Feitong worked at Baidu for four years, and was finally poached and jumped ship, completely because Baidu was going to go public. missed the project window, and she also had to do it, maybe she is still a little reluctant to be nostalgic now.

However, after Liu Feitong sang this sentence, everyone's attention came back to her soft timbre.

It seems to be a bit oolong, because of the first sound video installed on the computer in the studio. The song was not recognized.

"This young lady, please sing it again. We don't want the lyrics to be right, but the tune must be right and faithful to the original song. The current technical principle of Hatsune Video is to intelligently search based on tune and pitch, not timbre. ”

Liu Feitong was a little nervous, and quickly sang again.

Three seconds later, the computer started playing: "hidingfromtherainandsnow,tryingtoforgetbutIwon\-tletgo......"

"What's going on? It's actually an English song? ”

"Isn't this the English cover version of "Kiss Goodbye" that became popular last year!"

"Got the wrong song!"

When everyone thought that Gu Mojie was going to be seen as a joke, Gu Mojie smiled and signaled everyone to be quiet.

"Quietly, I said it, because when this software was developed, we took into account the difference in the weight of each person's timbre, so the comparison of timbre and articulation factors was eliminated when searching. Purely by tune search - the English version and the Chinese version of "Kiss Goodbye" have the same tune, and it is not surprising that the current most popular version is preferred. If you don't want this version, you can also select the function of 'search results are not satisfied, research for other cover versions of the same tune', and we will reorder the results by default. ”

Gu Mojie explained two sentences into the microphone, and then Liu Feitong in the recording studio did the same and operated the gourd, and the next second, what came out of the stereo was the version originally sung by Jacky Cheung.

This episode did not affect the proof of the power of Hatsune video and audio in the slightest, but instead proved that Hatsune Network did not set up a game to make a show.

A reporter who had been a little picky before stood up again and asked: "Mr. Gu, now it seems that the ambiguity rate of this software based on humming search is not high enough, and it seems that it can only be used in a professional recording environment." You can't use this kind of thing right away. ”

"You're right, so we're just doing a demonstration of this feature today, just as a beta version of the function point, and in the next two or three months, the technical team of Hatsune Network will continue to optimize it - don't forget, we are based on the 'deep learning algorithm' to do intelligent song search, so at the beginning we will require users to sing accurately enough to search, but in the future, as the sample size increases, our algorithm will be easier." Figured out the user's mind and adjust the popularity ranking to improve the search accuracy.

We hope you will have confidence in us that the power of any deep learning algorithm is not necessarily that it is accurate when it first appears, but that it is able to continuously learn and evolve itself. ”

Gu Mojie has no doubt that after this function is launched, his position in the domestic deep algorithm industry will be unbreakable. (To be continued.) )
