（ Please fast forward to 1 minute and 19 seconds to watch human-computer interaction) It is said that a smart speaker has recently appeared; It is not only a taste of life, bringing people different music experiences and enjoyment, but also has other more meaningful functions. It is designed and developed for primary school students. It is a smart speaker that can simultaneously support the functions of "personality radio", "Chinese dictation" and "English dictation". Can such speakers really help children learn? The author went to experience it with curiosity and came to share his experience with many parents.

Let's briefly introduce the appearance, The design of Youjia intelligent dictation speaker is similar to the small Bluetooth speaker on the market at present, without much innovation, but it still continues to be small and portable, 75 x 75 x 65mm Three dimensions 210g Its weight and specially treated colloidal material are more suitable for the daily safe use and carrying of primary school students.

In fact, Youjia is not a Bluetooth speaker, but an independent audio device LED Display and eight The physical keys are an important component to provide audio information and complete playback. When using the seemingly uncomplicated panel for the first time, we have to study the operation guide carefully to operate more accurately, because the main function keys are played by long pressing the menu key / Pause key. For primary school students, I think the product is simpler and more straightforward in key design.

8GB The built-in memory card and 1000mAh battery capacity can effectively guarantee the playing time and content of UniPlus. The connected playing time can be more than 10 hours. The actual experience of the embedded microphone also has a very high speech recognition rate. The universal MicroUSB interface has further improved the convenience of life;   Unfortunately, the Uplus smart speakers are not equipped with adapters and data cables when they leave the factory.

In addition to drawing the relevant information of the product, a rubber ring is also designed at the bottom, which can make Youjia more stable on various smooth desktops and suitable for various environments.  

As a learning speaker, of course, it has acceptable pure sound quality and sound effect, and the maximum signal-to-noise ratio is optimized >80% The sound quality is relatively soft, and this effect also makes children easier to accept and sound more comfortable.

In brief, although the Youjia intelligent dictation speaker is not a handicraft, with the simple and integrated overall design, the ordinary appearance looks very harmonious, and the color and shape are more suitable for children's choice.

Next, it depends on its real skills, Yes, that's right. The best thing about Youjia is its own function. It is an intelligent speaker that can help children learn and teach. It can understand literature, understand English better, and tell you beautiful children's stories. It effectively solves the problem that parents can't insist on dictating to children every day due to busy work, or English pronunciation is inaccurate due to regional accent.

One of the unique features: Youjia Radio and Chinese English Dictation

We can press ▶‖ Press the key to switch the stripes between the three modes of Youjia Radio, Linguistic Dictation and English Dictation. The LED display will also show the number of the radio or text to be compared, allowing the child to accurately select the current learning content,

In the actual experience, the dictation content is almost the same as the content of the version of the textbook, but due to the poor teaching content in various provinces and regions, there are also a small part of the content, which can not be fully synchronized. For the textbooks that are taught by people, they are basically the same. The practice of Chinese new words covers the fifth grade of primary school, while English new words cover the middle school. Those grandma and grandpa who don't know English can let go of their burden.

Unique function 2: learning method of voice interaction

When it comes to intelligence, of course, interactive experience is indispensable. The excellent voice interactive dictation method fully conforms to the dictation habits of primary school students. It is similar to teaching, reading, writing, and practicing in the classroom, with the functions of word formation, explanation, and how to spell, just like parents around.

The performance of speech recognition rate in the experience is relatively perfect, and the accuracy is very high; There is no unrecognizable phenomenon in the process of dialogue. Of course, all children need to do is listen carefully, answer and talk accurately.

Unique function 3: real-time update, cloud synchronization/management of learning content

Youjia can access the PC connection status by long pressing the menu key. The file management is similar to the mobile hard disk. The dictation content can be downloaded from the cloud through the Youjia assistant management software. The textbook content covers multiple versions of primary school Chinese, English and junior high school English.

For various versions of learning content, the content of the text is very comprehensive, including almost all the contents of the textbook. We can also download the courses needed by children through the convenient cloud.

First contact with Youjia

As a portable speaker that has changed the tradition, the smart function created for children's learning has broken the single function of portable speakers Problems. From the perspective of education, we can say that UniPlus intelligent dictation speaker should be regarded as a learning machine. Starting from the learning characteristics of primary school students, the dictation function has solved the problem that some parents cannot provide timely guidance for children; For the first time, Youjia has realized the new function of "channel" and "what you see is what you broadcast" on the portable speaker product, which provides the greatest convenience for primary school students to listen to radio dramas and English; In terms of educational content and Youjia assistants, I still hope to add more educational content of textbooks and Youjia assistants on mobile phones, which will make Youjia more practical and portable in learning.
