One, off topicWhen I first saw the Lenovo smart speakers, I thought of this: Amazon's echo. That's right, this similar appearance and voice operation process can't help but produce reverie. Is this product a copycat? Later, I saw Lenovo's smart speakers built-in Alexa voice service, everything goes without saying. What is Alexa voice service? Look at the following introduction:
On June 25, 2015, Amazon released the software development kit ASK (Alexa Skills Kit), which is a set of interfaces and toolsets of Amazon's voice service Alexa, enabling developers to easily create voice functions. Among them, Amazon Alexa is a cloud-based voice service that focuses on listening, understanding, and processing user voice requests, helping developers complete voice recognition and natural language understanding.
Amazon ASK Advantage: A new voice-based user interface; a new voice-based interaction; easy to use, easy to integrate in cloud-based services; free.
At present, smart speakers in the domestic market are Philips-based Alibaba-based Xiaofei, and X-Flight's DingDong based on Jingdong Micro-Link. Lenovo's influence in the field of smart homes, to be honest, is basically negligible. But this time, with Alexa's east wind, can we wait and see?
Take a look at this video, Lenovo will describe the future of smart homes as sci-fi. In the near future, we believe that our lives can be as comfortable as the video.
Lenovo's smart speaker packaging box adopts the way of halving up and down, the high-density foam in the lower half just wraps the speaker tightly, but the user's manual and power adapter packaging of the upper half is more difficult to come up with.
Speakers are available in 5 colors. This time the survey was sent randomly and sent me green. It was a bit disappointing at first, but after seeing the real thing, I felt pretty good. It was not the kind of dark green, but a kind of shallow. Shallow grass green. There are also speakers in grey, silver, orange and black. Black is a special version. Working with Harman, the sound quality is better, of course, the price will be higher.
The top of the speaker, and echo is still a bit different, and more than a recessed hanging design, it is even more sci-fi. The white box feels a little pearly white, and the top chrome light ring can be rotated steplessly, which should be used to adjust the volume.
The green part of the lower part feels very rough and has an original ecological style. Some friends may be disgusted with this, preferring some of the metal, cold design, Lenovo's design department to consider if it is good.
There are 8 slightly larger holes on the top, 6 in the surroundings, and 2 in the middle. This is an array of 8 microphones used to ensure the accuracy of voice command picking. The central button is used to manually operate the switch and other functions, press the touch in general, there is no feedback.
The bottom half of the speaker is concave, the side is the power interface, so that the power cord interface is more subtle, the overall appearance is more smooth.
The power adapter input is global voltage support and the output is 20V 1.5A. Does this speaker have such high power?
Turn on the blue LED bar at the top and it's cool.
Putting it in your home is also in harmony with your home environment.
In order to let everyone have a deeper understanding of the product, open up. The bottom silicone lid is affixed with double-sided adhesive. It is easy to smash down, and then start to remove the back cover. After the back cover is removed, this is the power connector and reset button.
Then remove the power and then remove the 4 screws, and then push out the green speaker cover. The speaker part of the speaker can be seen.
The horn on the outermost side is smaller, and it is estimated that it is an treble unit. The horn manufacturer is not marked.
The gap between the two speakers.
The following speaker is slightly larger and should be a woofer. It is screw-free and pressed by the upper unit.
The iron body on the back of the horn looks thick, and the same manufacturer is unknown. Amazon's echo focus is not the sound quality, it seems that Lenovo is exactly the same. Fortunately, Lenovo also has a black Harman paragraph, the pursuit of sound quality friends can think about it.
Then move down, the main board part of the upper half of the speaker can be seen. In the Lenovo LOGO is the main board below, there are many side-valued friends say that the heat is more serious, it seems that the board's heat. Wifi antennas are on the left and right, with glue on both sides.
The inside of the upper part is an inverted tube and it is said that you can make the low frequencies better.
The side is the outlet of the inverting tube.
Removed half and continued to disassemble the motherboard.
The back of the motherboard is equipped with a heat sink that is as large as the motherboard. . . Is there such a large amount of heat?
Remove the metal shield on the outside of the motherboard, you can see the network card to connect the outside Wifi antenna, flash memory and other components.
Wireless Bluetooth network card model is RTL8723BE, up to 300M, Bluetooth 4.0. However, there is something wrong with it later.
Remove the heatsink to expose Intel's CPU, which is Intel Atom x5-E8000 1GHz. Intel Atom's CPU is mainly used on Windows tablets, performance can also be, the main advantage is cheap.
After dismantling the material used to feel the sound of this speaker, the components are considered to be quite satisfactory, and the Wifi antenna's alignment is rather bizarre.
For the first time using smart speakers, you need to configure the phone App for networking, download and install "Smart Lenovo" App, add the logo of the Lenovo smart speaker on the main interface, select the current wireless SSID, fill in the password. The speaker only supports 2.4G wireless. If using 5G, please switch to 2.4G first.
Wait a moment, the speaker can be configured.
At this time, the main interface will add a Lenovo smart speaker bar, click to open. You can see that there are seven major functions: Cool Music, Himalayas, Reminder, Memorandum, Didi Trip, Voice Record, and Voice Message.
Click "..." in the upper right corner to set up the speaker. The news source is only NetEase for the time being. You cannot select other.
After upgrading the app once, the news source became “hearing,†and the speaker firmware was automatically updated once. The version was updated from 3052 to 3058, and the operating system version was changed from null to 11.1.27.
All voice commands are found in the voice record. The question is, how do I do not want it to record so much? Can not delete it! Lenovo engineers, come to clear all the records with one click.
The instructions in the speaker package are relatively simple. If you need more detailed instructions, you can scan the two-dimensional code provided on the manual to obtain more instructions for voice instructions. You can also directly visit the following website: http://pub.lenovo.com.cn/upload/SpecificationFiles/1480585983/cn/smartassistant_ug.html
There is a complete set of voice commands in the user manual. Look, it's better than nothing.
After you are familiar with voice commands, you can freely operate the speakers. You can also try it yourself without looking at it, but according to experience, it won't be true.
In any part of the room, say "Hello, Lenovo", you can activate the Lenovo smart speaker. The light blue LED on the top of the speaker will light up and wait for your voice command. When the command is finished, the speaker recognizes that the command intends to issue the correct operating instructions. If there is a voice confirmation, the speaker will also simulate talking by means of light and dark changes on the LED bar.
The stepless knob on the top of the speaker can adjust the volume, of course, can also be adjusted by voice commands, but the trial found that when using voice commands to adjust, in order not to appear stupid keep shouting “Hello Lenovo†situation, the system only set Several levels fix the volume, there will be a case where the sound is too small when it commands it to a little sound.
Voice conversation record:
Hello, remind me to bring an umbrella tomorrow.
Tomorrow, Beijing will not use umbrellas and it will be cloudy. The temperature will be minus 6 to 7 degrees and winds will be 4 to 5.
Hello association, remind me to go to the bank.
Memo settings are successful.
Hello association, what do I have to do?
Memo settings are successful.
Hello, Lenovo, what have I not done?
Memo settings are successful.
(Then there are three memos in the memorandum. Is this memo only visible through the mobile app?)
Hello, remind me to buy an apple.
Memo settings are successful.
Hello Lenovo, don't need to remind me to buy an apple.
Where do I come from?
(Small humor? However, there is no cancellation of the memo)
How are you thinking now?
Please specify the specific date.
Hello association, will the temperature of 9 o'clock on January 25 be?
It's sunny, of course!
(A bit of donkey is not on the tail!)
Hello Lenovo, how is the weather today?
Beijing is fine today, temperatures are 4 to 5 degrees below zero, breeze.
(If I'm in Beijing, this is fine, but I'm in Yangzhou. Can programmers set default locations?)
Hello, Lenovo, what news does Yangzhou have today?
Sorry, your message was not found. It may be canceled.
(Failed, how the news came together with the message)
Hello Lenovo, what news today?
Today, Yangzhou does not use raincoats, it is cloudy, the temperature is 1 to 11 degrees, and the wind is 3 to 4.
(Strangely, I don't have Yangzhou in this sentence. Does it seem to have contextual association?)
Hello association, play financial news.
(ignore me)
Hello association, play sports news.
(ignore me)
Hello association, read news and hear.
A news broadcast on January 5th (today is 25th, it seems this news is older)
How do you think 18 equals 18?
18*18=324.
(This is good, what small calculations later ask directly)
Hello association, come to a bread.
(ignore me)
Hello association, I want to hear saxophone.
(ignore me)
You think of it, listen to the song.
Recommend Refrain from Anan Ryoko to you.
How do you think of it, change your song?
Recommend Refrain from Anan Ryoko to you.
(It seems that I don’t understand what it means to change songs)
Hello association, come rock.
Recommend Refrain from Anan Ryoko to you.
Let's think about it, let's play light music.
Recommend Refrain from Anan Ryoko to you.
(This Refrain really so nice?)
About music playback: There will be a voice prompt before playing and XXX XXX is playing. If you let you put a song, it will keep playing this song, and before the complex play, you can use voice prompts to play XXX's XXX. Am I a little bit critical?
About Voicemail: This requires two speakers to be used and failed to test.
About a taxi: This feature is a little tasteless, the order can not see the process, you have to use the app, no practical significance.
About Bluetooth: Bluetooth can be turned on using the voice command “Hello Lenovo, Turn Bluetooth On†or double-clicking the top button. Bluetooth voice can still use voice "Hello Lenovo" stimulating speaker, even Bluetooth music and wireless playback at the same time, the speaker instructions that read "Bluetooth connection mode, this product can not accept voice commands, can only achieve ordinary Bluetooth Play function.†In the previous version, this was indeed done. Later in the new firmware version, the engineer may feel that the switch is too cumbersome and not as good as the two. However, it is possible to do Bluetooth wireless connection, but Bluetooth connection can be suspended.
About the sound quality: The sound quality of the small speakers can only be said as normal, but it can be heard, but it is not outstanding. The maximum volume can be considered a big voice, but there are broken sound, or low-key point.
On the issue of wireless connection: What makes people feel bad about their mouths: What kind of feeling is the voice of a “networking successful†woman suddenly heard at night? This happened two more times! At 4 o'clock in the morning, I came again and I fell. If it crashes and restarts, you don't know it. If it is a network disconnection, there is no need to say so loudly when reconnecting! In the course of normal use, there have been several disconnections, and it seems that wireless connection is a big problem.
Lenovo smart speaker is Lenovo's important piece in the layout of smart home, natural and accurate human-computer interaction relationship to whether it can become the entrance and center of smart home. From the results of this trial, Lenovo still has a long way to go. In terms of accuracy of speech recognition, diversity of voice commands, understanding of natural language, etc., more technical accumulation is needed.
There is reason to believe that artificial intelligence will come closer and closer to us. To grasp the opportunities in the future, it is inevitable that technology will be the first priority, and marketing is not the right path. Lenovo, are you really OK?
Suggest:
Integrated infrared and RF remote control functions, voice control for remote control of home appliances;
Improve product stability and avoid frequent dropped calls;
Further improve natural language understanding and make products more humane;
Increase the built-in battery support, or wireless charging function to improve convenience;
You can customize the activation language, always called "Hello Lenovo" feel a bit silly ah;
Built-in broadcast radio module, you can choose to play the radio voice or regularly open the broadcast.
It's time to lie in a rocking chair and move your mouth to listen to the music you want to hear...
