When the head of the household returns home, the indoor lights will automatically turn on and the room temperature will be adjusted to a suitable temperature;

At the same time, a small butler similar to Siri will also intimately tell you which households to add, and the steps will not bother you. As long as you give an order, Siri will place an order online;

When you are away from home, your car can achieve perfect self-driving without worrying about road conditions and road recognition problems.

Do you think you just played like this? The excitement is yet to come-

If you make some illegal operations while driving, Siri is absolutely unhappy and will remind you in time.

You must think this is a scene I imagined, but it is not. This is a scene from the foreign science fiction thriller "Upgrade" that was released just a few days ago. But it may be mapped into our real life scenes soon.

On the surface of the smart speaker market, the situation is very good

In the current wave of artificial intelligence that has set off globally, smart speakers, as the best entrance to a new human-computer interaction experience, have become the breakthrough point for the world's technology giants to open the door of AI. At present, the smart speaker market is still led by Amazon Alexa, followed by Google, while Apple Siri and Microsoft Cortana are still struggling to catch up. According to news from [TechWeb] on August 7, Amazon has sold more than 50 million Alexa smart speakers around the world with this wave of craze, and hopes to use this opportunity to integrate its own products with smart speakers.

Back in the country, with the continuous blessing of BAT and the full deployment of other Internet unicorns that are not inferior in strength, the domestic smart speaker market has also ushered in unprecedented rapid development. According to Canalys’ latest statistics, among the global smart speaker market share in the second quarter of 2018, China’s smart speakers performed very strongly. Among them, Google ranked first, Amazon second, Tmall Genie third, and Xiaomi fourth.

It is worth mentioning that Xiaomi, as a mobile phone manufacturer of the post-homicide Internet, quickly breaks through layers of defenses and enters many areas by virtue of its "high cost performance" and "explosive models" model. It has established a strong Xiaomi ecosystem, and smart speakers are among them. A brilliant stroke.

From last year to now, Xiaomi Zanu has a 12.2% share of the entire market. We see that Xiao Ai is very popular in the domestic market with a very low price. Different from other manufacturers, Xiaomi puts the threshold of smart speakers very low, and has opened up the voice assistant of Xiaomi mobile phones, using deep learning algorithms to achieve good performance results. In the past 15 days, Lei Jun announced that Xiao Ai’s monthly active devices exceeded 30 million. This is also the best news that Xiaomi has heard since its IPO.

It can be seen that, whether in foreign countries or in China, the overall performance of the smart speaker market seems to be pretty good, and the situation is very good. But is this really the case?

The controllability of intelligent voice is worth worrying about

The world's giants are all competing for the super entrance of smart speakers to AI, but it does not mean that this entrance is mature enough, but the giants do not want to miss this best entrance. In fact, smart speakers are just a carrier. The core lies in the intelligent voice interaction system (ie voice recognition) onboard. As an important basis for research on AI, voice recognition is technically incompetent in terms of semantic comprehension and recognition accuracy. To the point, it is worth worrying about voice control after being equipped with smart speakers.

Although after considering the competitive landscape of the global voice market, according to the latest news from foreign media, the two voice assistants of Amazon Alexa and Microsoft's Cortana are officially married. But it may still not be able to achieve the perfect shape it expected, such as being unable to play some online music services.

This is not the most important thing. The most important thing is that you cannot master the controllability of the voice. Simply put, you don’t know when you will wake up siri unintentionally, and you don’t know when your conversation has been affected. Eavesdropped, when the courier brother suddenly sent you a package, you still looked dazed.

According to the author's knowledge on Leifeng.com, a strange news occurred abroad, and Amazon Echo assisted the police in avoiding a murder. When a foreign man had an argument with his girlfriend, the man pointed a gun at his girlfriend and questioned her: "Did you call the sheriff?" The Google Home next to him heard the order to "call the sheriff", so he also It was executed as ordered. Finally, the SWAT team arrived at the location of the incident and safely prevented the incident from happening further.

This seems to be a good thing, at least Echo can help you solve sudden dangers and situations. But the next case will have to make you unlovable and even horrified.

It is said that a foreign doll company aired an advertisement for Doll’s House on TV. Amazon Echo of several families in the area automatically started to order Doll’s House online after hearing the advertisement. That’s not to say, the Intelligent System Security Laboratory of the School of Electrical Engineering of Zhejiang University even successfully launched a "dolphin attack" on Amazon's speaker Echo. By exploiting the hardware vulnerability of the microphone, it successfully "hacked" into the voice assistant system of smart devices. , By emitting an ultrasonic voice that cannot be heard by human ears, let the voice assistant execute the instructions they give, such as asking Echo to buy something on Amazon.

Even more shocking is that researchers at MWR InfoSecurity discovered that there is a security hole in the old Amazon Echo smart speaker. Hackers can turn the Echo speaker into a bug without affecting its overall efficacy. The principle is that the researchers connected the Echo to the laptop and SD card reader through a plug made. Then use the debugging tool to crack the Echo system, and write a special boot program into it. And all audio streams heard by this Echo will be automatically forwarded to his remote server. The key is that the other functions of this smart speaker seem to be all normal.

That is, if the smart speaker is invaded by illegal hackers, the user's large amount of data and privacy will be threatened.

Spoken language is still a barrier that speech recognition is difficult to break through

Returning to the accuracy of semantic recognition, although the world has made continuous breakthroughs in AI technology, the accuracy and comprehension of speech recognition have also reached the point of perfection. For example, there have been media reports that Google Assistant will be released in 2018. By the end of the year, more than 30 languages ​​will be supported; in addition, Qualcomm has developed a voice recognition device that can recognize words and phrases with an accuracy rate of 95%.

However, if this is used in the Chinese test, it may appear to be very low. As we all know, after thousands of years of cultural change in China, its characters have become elusive, especially since there have been more than 30 languages ​​with strong local characteristics, even the Chinese may not be able to understand and understand. Needless to say the lifeless machine speech recognition.

For example, in a study, someone used the Alexa test to identify some non-native spoken languages, and the results showed that the inaccuracy rate could reach 30%. In the face of people who speak English with Spanish and Chinese as their first language, whether it is Google Home or Amazon Echo, the recognition rate is low and scary.

Write to the end

All in all, it seems that speech recognition still has many barriers that cannot be broken through in a short period of time. Giants seize a large number of smart speakers market, just because it is the best solution to link AI to the bedroom. While the giants have seized this entrance, it does not mean that he has mastered the super entrance of AI. It still needs continuous research and breakthroughs in the improvement and innovation of speech recognition technology.

Otherwise, even if you seize the super entrance of smart speakers first, you will still be easily surpassed and replaced by latecomers as smart speakers continue to usher in the upgrade battle. After all, AI is a field with extremely strong technological innovation. Only by continuous technological innovation and iterative upgrades can it be possible to tide over this upgrade war steadily. As for whether it can become the benchmark of the industry, at least it must survive first!
