preface:

I believe many people have some understanding of iFLYTEK. I believe many people have used iFLYTEK input method. I can say that iFLYTEK's voice recognition is very powerful. As a company specializing in intelligent speech and language technology research, it is certainly not limited to speech recognition research. Speech can serve as a good bridge to communicate with hardware in the current intelligence. As many people say now, the control mode of smart products still needs the assistance of mobile apps. The process from finding apps to controlling the corresponding products is actually tedious. What's a better solution? At present, voice is a good way.

JD has made great efforts in intelligent products in the past two years. At present, there are many products connected to JD's intelligent platform, all of which have been connected to JD Weilian for control. The biggest highlight of iFLYTEK is that I can control the hardware products connected to JD Weilian.

[Unpacking part]

The product packaging of Dingdong smart speakers is very simple and beautiful. A large kraft paper box is printed with only a few words of Dingdong smart speakers. Of course, I prefer this kind of packaging. The simple style will give you a comfortable feeling at a glance. This time, the speaker box is also unexpectedly large and heavy, which makes me look forward to the speaker.

The box is a box type package, and iFLYTEK Voice and JD+are printed on the bottom information, indicating that this is a super speaker jointly created by iFLYTEK and JD. From the label on the outer package, I got the black limited edition of the internal test. Of course, the internal test machine will inevitably have some bugs, which is completely understandable. Most of the bugs in the mass production version should be improved.

When you open the box, you can see that the speaker is not so big. This big package is mainly for better protection of the speaker. The upper part of the speaker body is cylindrical, and the lower part slowly has four sides. Both the upper part and the lower part are fixed with foam plastic to prevent the speaker from being knocked during transportation, Most of the space is actually used for buffering.

Take off the plastic protective film and pull closer to see more carefully. You can see that the speaker is lying on the semi-circular foam, which is well fixed and well protected. The paper box on the top of the speaker contains the power supply and instructions.

Product Analysis

Although it is slightly smaller than the packaging box, the overall volume of the speaker is still very large. The upper part of the speaker is made of plastic, the middle part of the speaker is made of metal speaker protection net, and the bottom is also made of plastic. However, the combination part of the speaker is handled very well, and the detail workmanship is commendable. I still feel that the overall plastic material of the speaker is not very beautiful. If the upper and lower parts of the speaker are made of metal like the metal mesh in the middle of the speaker, the speaker will have a higher pressure grid, and the weight will further increase after the use of metal materials, which will help to improve the sound quality of such a smart speaker that is not portable positioning.

The top part is a touch pad, and the middle part is a key printed with JD+logo. The key function is to press voice search for a short time, press and hold to prepare for networking. After pressing, there will be corresponding voice prompts, which is very simple. Below JD+is the pause button. On both sides are the previous song and the next song buttons. The heart-shaped button is the collection button, which can be used to collect both songs and radio stations. The long string in the middle is a distinctive volume key. If we need to increase the volume, we just need to slide from - to+. These operations will be displayed through a circle of led light strips around the top, which is very scientific. In the process of use, the touch experience of these keys is relatively good, and the response is rapid.

The led aperture on the top, when we wake up with voice, the dingdong time circle will flash blue light. When we adjust the volume, the time circle will indicate the current volume by the length of the aperture. For example, if the current volume is half, the aperture will only be half bright, which is very cool. Of course, other operations will cause corresponding aperture changes, which is a beautiful reminder.

The middle part is a metal protective cover, which is of good quality and feel. This whole circle of densely spaced holes believes that iFLYTEK's sound processing on the speakers is very good.

Another special thing is that dingdong is different from ordinary speakers. Its power cord is inserted from the bottom. In order to ensure stability and beauty, the power cord is led out from the bottom of the speaker. A small round hole is opened at the bottom. In fact, I think Dingdong can be used as a power base with power cord, In addition, if we want to use the speaker, we just need to put the dingdong into the base instead of plugging the power cord into the bottom of the speaker.

When placed on the plane, you can see the power cord hole at the bottom of the speaker. From this close distance, you can also see that the combination part of the speaker is very well made. There is no burr, which is very factory like.

This is the case after the power cord is plugged in, so hiding the socket at the bottom can make the appearance of the product more simple and beautiful. Judging from the bottom parameters, the power of dingdong is quite high, because the power supply used is 15V/1.6A. According to the official introduction, dingdong uses four full frequency units plus a bass unit. I don't know how the five unit speaker performs under iFLYTEK's tuning. The bottom is also marked with iFLYTEK Voice and JD+, indicating that dingdong was jointly created by these two companies. Of course, the large rubber pad at the bottom has the function of anti-skid and anti resonance.

I can't help praising the power supply that iFLYTEK matches this time. Although it is large, the surface of the piano like surface is better than the plastic part on the speaker, which makes people reluctant to remove its protective film.

The input voltage is 100-240V 1A, and the output voltage is 15V/1.6A. When I saw the size of iFLYTEK, I thought it would have its own battery. What I didn't expect was that iFLYTEK only had power supply, and there was no built-in lithium battery. Therefore, when iFLYTEK was running, it had to plug in the mains power at all times, and it would be impossible to play when the power was cut off. This design was still a bit inappropriate, If you want to move, you must disconnect the power supply first. It's not user-friendly. I still hope that the mass production version can be equipped with built-in batteries.

JD+is available everywhere, but it is obvious on the power plug. Sifang's power plug is missing a corner, which is directly printed with a big+sign. I believe this is JD+. It seems that the cooperation between iFLYTEK and JD is relatively close.

The product is very simple. All the accessories are power supply and instructions. There are no spare parts.

APP experience

Settings

I will not say much about the networking process of dingdong. Acoustic connection is still very common. If the operation mode is correct, the connection process is very short.

The main interface of this app is awkward. I want to say that it's too wasteful. It's useless to put such a large speaker here. I hope we can replace the main picture of the speaker with some other practical functions without wasting a main interface. In my song list, we can see the songs we have played recently, as well as our favorite songs and various cached songs. The content of the audio library is very rich. All radio stations with music and various personalities can be on-demand. Of course, you can also search for your favorite songs. Singles, albums, songs, etc. can be found. Listen to what you want to hear.

The simplest of all, of course, can also call for songs by voice, I would also like to focus on the interrupted wake-up of dingdong. The top of DingDong smart speakers is equipped with eight evenly distributed microphone arrays, plus multi-channel echo cancellation technology. This smart speaker can filter out various background noises, including music being played. As far as the smart speakers on the market can support interrupted wake-up, I haven't seen it yet. In the case of normal volume playback, we can call dingdong to interrupt wake-up when it is close to dingdong. The success rate in the use process is still high, but it is difficult to wake up when the song volume is large. However, various software and hardware optimization will certainly be carried out in the later stage. I believe that the voice manipulation in the later stage will be very powerful.

Both the song list and the radio station have the records that we have listened to recently, and the records that we like to collect should be concise.

In fact, I haven't used the reminding function yet. It's hard to imagine using such a big guy to remind. If the volume is not well controlled, it's still a bit unbearable.. Of course, you can try..

In fact, what I regret most during the use process is that there is no JD Microlink product on hand, and there is no way to test the control function of dingdong's highlight hardware. When there is an opportunity to purchase products connected to the JD Microlink platform later, we must use dingdong to control and try.

It is also the first time to see the replacement of wake-up words in the current smart speakers. In fact, it is better for users to customize wake-up words. Of course, there are some limitations in the current technical implementation, but it is also a great progress for dingdong to support the replacement of built-in wake-up words. I replaced Bailing and Xiaowei for a voice manipulation test. The test result is no different from that of using dingdong wake-up. The recognition is still the same accurate. Of course, we can also choose male or female voice for broadcast. In fact, we can add some more voices to make it more personalized.

As for speakers, we can see that the total capacity of dingdong is 2.09G, and it has reached 1.74G in use. Therefore, dingdong is mainly online on-demand, and there will not be too many locally cached music.

[Content]

We can see that the content of dingdong sound library is rich enough. At present, dingdong supports Baidu Music, Migu Music and Himalayan FM, which can be said to basically cover most of the content of listening. All kinds of music, crosstalk, skits, operas, children's stories, storytelling, etc. can be on-demand to ring your mind.

Summary

It can be said that iFLYTEK's ability in speech recognition is obvious to all, and JD Microlink, the big platform, has the ability to turn dingdong into the control center of smart home products. It can be said that the strong combination of JD and iFLYTEK is very suitable. At present, there are nearly 400 types of intelligent hardware on JD Microlink. If these hardware can be controlled through DingDong, you can imagine how powerful a voice control platform it is.

Of course, when it comes to control, there are still some imperfections in the current dingdong smart speakers themselves.

---Dingdong has no built-in battery and no switch. If you want to shut it down, you must unplug the power supply. This is a very inconvenient operation.

---At present, dingdong can only play songs online through wifi. I think it is very wasteful for such a big thing as dingdong. I really hope to add Bluetooth or 3.5mm audio input port to provide speaker utilization.

---Although dingdong uses five units, the four units are opposite to each other in four directions, and the stereoscopic effect is really poor. I hope the design can be improved in the future.

---The speech recognition rate can also be better. I believe that iFLYTEK can do it with its strength.

---I hope the app can do better, with more perfect functions and beautiful interface.

Although there are many things that need to be improved, what iFLYTEK has done so far is much better than many smart speakers on the market.

---The voice interaction experience of iFLYTEK is very good. With the microphone array, it is much better than other speakers.

---At present, there are so many products connected to JD Microlink, dingdong, which is also very practical. It is not said that you can't find matching products after you buy speakers.

---Of course, the four full frequency units are opposite to each other in four directions, which is both a disadvantage and an advantage. This can take into account the listening experience of people in all directions.

It is hoped that dingdong can do better and better. The smart home voice control center is very necessary and important. After all, the experience of opening an APP on a mobile phone is not friendly, and voice in home control is more reliable.
