To put it simply, it is to implant a plug-in called Alexa in the browser and feed back the relevant information of the webpage being loaded by the browser to the Alexa database, so as to measure the level of the website. This Alexa database counts the ranking of page views every three months, which is the legendary Alexa ranking. Alexa ranking is calculated according to the proportion of netizens who have installed Alexa plug-ins, so Alexa ranking is actually very inaccurate for websites and sites with low domestic traffic. For general websites: personal websites, company websites, online stores, etc. Alexa ranking has no practical use. It is suggested that websites with daily ip traffic below 1000 should not waste time in this respect. Artificial intelligence assistant ranking?

At present, the development of artificial intelligence technology mainly has two forms: the processing of graphic and image information and the processing of speech recognition information. As we all know, at present, the field of intelligent voice assistants has formed a four-strong pattern, namely Apple Siri, GoogleAssistant, Microsoft Cortana and Amazon Alexa. As a new dark horse in the second half of this year, the strength of Samsung Bixby should not be underestimated. The application of these voice assistants in mobile terminals has accelerated the popularization of artificial intelligence to varying degrees.

Samsung Bixby

Let's talk about the recently released Samsung Bixby. Samsung Electronics released Bixby2.0 in San Francisco on June 65438+1October 65438+August. Samsung claims that by adding a dual-engine natural speech understanding module, it can understand complex instructions and identify words with incomplete information. Bixby also has the ability of context awareness, which can understand the current usage environment and application status, support wake-up at any time, and facilitate the next operation. Based on the machine learning mechanism of artificial intelligence technology, Bixby has the machine learning ability and can learn the owner's usage habits independently.

In terms of application scenarios, Samsung Bixby supports native applications such as telephone, photo album, clock and weather, and Bixby (Chinese version) is also compatible with nearly 20 local third-party applications in China. Samsung claims that Bixby-enabled applications have the ability to understand the context, understand the user's intentions more accurately, and understand and execute the user's voice commands when the information is incomplete or the sentence order is wrong.

In addition, it is reported that Samsung recently acquired Fluenty, an intelligent voice assistant company, to improve Bixby's text processing ability. Fluenty previously provided automatic SMS service for third-party social services such as FacebookMessenger and Telegram. At present, people's use of smart phones is more complicated. In addition to voice input, text input is also needed as a supplement.

Apple Siri

Siri is an intelligent voice control function introduced by Apple when it released the iPhone4S on 20 1 1. Apple originally defined Siri as an intelligent assistant, when Apple mentioned the concept of "intelligence". At the beginning of Siri's release, there were not many practical functions, such as few languages, slow response and poor semantic understanding.

Subsequently, Apple opened the connection between Siri and native applications such as phone, map, music, reminder and HomeKit, enabling Siri to handle simple tasks. In addition to the iPhone, Apple also integrates Siri into devices such as iPad, iPodTouch and AppleWatch. In 20 16, Apple opened the interface between Siri and third-party applications, and Siri realized the interactive function based on third-party applications. At the same time, Apple also realized the interactive connection between Siri and AirPods Bluetooth wireless headset.

This year, with the hardware support of A 1 1 bionic chip, Siri is expected to alleviate the shortcomings of poor semantic understanding and insufficient intelligence. What Apple's Siri urgently needs to solve is ecological construction, such as expanding into the smart home field. Therefore, compared with the increasing performance of Apple hardware products, the progress of Apple Siri is too slow.

Google Google assistant

2065438+In May 2006, Google officially launched GoogleAssistant voice assistant at the I/O conference. In terms of time, it is indeed several years later than Apple Siri. It covers all the functions of GoogleNow, such as voice command, voice search and voice control, and is generally regarded as an upgraded version of GoogleNow.

At the 20 17 Google I/O conference, Google declared that GoogleAssistant is an important service carrier in the field of Google machine learning, with many updates in voice, text and images, and formed an interactive AI experience centered on individuals. Google said that GoogleAssistant is compatible with most Android phones, smart home appliances, GoogleHome, AndroidWear2.0, AndroidTV and other hardware devices, and can even be used for iPhone in the form of an app.

Microsoft Cortana

20 14 in July, Microsoft officially released the Chinese version of Cortana at the China windows phone 8. 1 update conference, with the Chinese name "Microsoft Xiao Na". It should be noted here that Microsoft released Cortana as the world's first personal intelligence enhancement. Moreover, at the end of 20 16, Microsoft announced that Cortana would be opened to a third-party hardware company, which could be integrated into various hardware such as audio, home appliances and automobiles.

The difference with other voice assistants is that Cortana is not a storage type, but a dialogue process. But it is still based on machine learning and artificial intelligence related technologies. It learns users' behaviors and habits, and uses cloud computing, search engines and unstructured data analysis to complete voice command tasks.

Amazon Alexa

Alexa was quickly known by Amazon's smart speaker Echo. On October 20 14, 165438+ 10, Amazon launched Echo, paving the way for Alexa. 2065438+In June 2005, Amazon announced the opening of its artificial intelligence voice assistant Alexa, so that third-party developers can develop voice-based skills on Alexa platform.

Alexa can realize weather query, problem communication, taxi support, menu query, home appliance control and other functions. Alexa is not only used in its own products, but also includes LG's smart refrigerator and Lenovo's smart speakers. Although powerful, Alexa does not seem to have a tendency to develop in the direction of smart phones.

We see that the current mainstream AI voice assistants in the industry have similar functions. These voice assistants are all based on artificial intelligence and machines to realize the interaction with human voice and text. When the whole artificial intelligence of human beings is in the primary stage, these voice assistants have limited functions and cannot be called "AI assistants". But it spans the layout of smart phones, home appliances and cars, which can greatly promote the production and life of artificial intelligence.

How to use Amazon exa?

1. Click the icon in the lower right corner of the home screen. Therefore, we found ourselves on the "Devices" page and found various devices connected to Alexa.

2. After selecting the "EchoandAlexa" equipment group, select the connected speakers.

The next page provides you with information about customizing various Echo functions.

3. You can change the device name, adjust the volume, and change the time zone or measurement unit as needed.

At the bottom of the page, the About tab provides you with information, such as the Mac address of the speaker, which is necessary if your Wi-Fi network is configured with Mac filtering.

4. If your device doesn't appear in the Bluetooth device section, click "Pair New Device".

Alexa will then search your device and pair it with the connected speakers.

5. Go to the Bluetooth settings of your smartphone to authorize the connection.

In our example, the name of the speaker you found is as follows: Echo-03Q.

"Do not disturb" mode

Also in the application settings, the "Do Not Disturb" mode allows you to choose the time period when Alexa must remain silent. However, the alarm clock and timer will remain active.

Change Alexa activation words

Finally, although we may regret that Alexa doesn't allow us to choose any word to activate it, Amazon still lets us choose between three different words: Alexa, Amazon or Echo!
