For office workers and media workers like me, in the conference records, interviews, participation in conferences, voice memo, etc., because of the more voice information obtained, it is obviously unable to remember it. Slowly finishing is the best solution before. Today, the intelligent recording pen blessed by AI technology can recording and transliterate at the same time as the meeting, which greatly improves efficiency. At the same time, in the noisy environment, the recording quality of the intelligent recording pen is much better than the mobile phones we used in the past. HKUST Xunfei has always been the leader in the field of “voice technology”. Its smart recording pens are also very good. It has just released a new generation of Xunfei Smart Recording Pen SR502. As an upgraded model of SR501, it has not small in hardware and software. upgrade.

The traditional recording pen only has the function of recording sounds. In the face of fast -paced office needs, it is obviously too low. HKUST Xunfei SR series intelligent recording pens can not only achieve the recognition, recording, recording, recording of traditional high -end recording pens. Clear, at the same time, combined with the AI ​​algorithm, the recording can also be transferred in real time, which greatly improves the efficiency of later finishing. Based on the SR501 recording and conversion function this time, SR502 has added offline transposition function. You can also provide voice conversion text functions without the network. At the same time, a high -definition camera can be added to support OCR text extraction. It can also generate subtitles in real time, which is very convenient.

Appearance upgrade: full of technology, exactly like high -end mobile phones

Compared with SR501, the appearance of the SR502 SR502 this time has been greatly upgraded. The front glass covers the front, the screen is increased to a larger 3.5 inches, and the resolution is 480*800; A array microphone, coupled with the top 2 orientation microphone at the top, use different microphone combinations in different scenarios to match the corresponding scene algorithm to ensure the recording effect and playback. Products with the longest distance.

When I first saw the SR502 of Xunfei Smart Recording Pen, there was a familiar high -end mobile phone feeling. The front glass cover on the front was very similar to full screen. The entire body adopts a metal body that takes into account the texture and beauty. The four corners are round design, and the color of the starry sky gray looks very high -end.

The button layout of the fuselage is similar to the mobile phone. On the right is the power button and the SIM card slot; on the left is the recording key and volume addition and subtraction keys, which meets daily use habits.

As a smart recording pen, the system of Xunfei Smart Recording Pen SR502 is based on Android 8.1 deep customization, similar to the operation of Android phones; the newly upgraded HKUST Xunfei Writing ED engine is based on the end -to -end voice recognition framework. Chinese and pure English mode recognition, while supporting Sino-British mixed recognition scenarios, and mixed recognition of Mandarin-some dialects to achieve seamless switching of language.

Based on the new generation of conversion engines, in addition to online transliteration, SR502 can realize the real -time transfer of the text without network. No 4G/WIFI network is required, and voice can still be transliterated in real time, and the accuracy of offline conversion is 95%; closed conference rooms and many press conferences often encounter bad networks. No fear of breaking the net. The content of offline transliteration is preserved immediately, which is safer to highly confidential content. If you want to obtain higher accuracy, you can write up and write after the Internet.

The SR502 is equipped with a 8 -megapixel camera that can intelligently extract text information in PPT, Excel, and in the picture. When the office encounters PPT that needs to be transferred, you can switch to text when you shoot, and quickly edit and share. For office, this can greatly improve efficiency, such as paper materials, some PDF documents that cannot be copied, etc., you can switch to text into electronic files by taking pictures directly.

Use SR502 to shoot VLOG and short videos, you can generate video subtitles in real time, automatically detect Mandarin and dialects, 7 foreign languages, and ethnic minorities. After recording, the subtitles are automatically saved and supporting subsequent editing. However, due to the restrictions on the storage space, only 5 minutes can be recorded within 5 minutes. I hope that the subsequent support expansion can record longer record videos.

The top 2 diameter 10mm directional microphone+6 matrix microphone, based on Xunfei -deeply customized Voice Cube sound cubic technology, the farthest pick -up distance is 15 meters. more acurrate. Xunfei’s FOCUS ++ intelligent noise reduction technology actively recognizes human voice according to the scene, while reducing environmental sound interference to make picking up clearer.

The basic functions have also been upgraded this time, and the accuracy of the transformation of the voice is 98%. Save the recording uploaded clouds to complete the transposition, and the accuracy rate is higher. The newly upgraded A.I. transliteration engine, in addition to the identification of pure Chinese and pure English mode, also supports Chinese and English mixed reading, Mandarin and some dialects. In addition to Mandarin, Chinese voice recognition supports 12 dialects, including Henan dialect, Cantonese, Sichuan dialect, Yunnan dialect, Guizhou dialect, Tianjin dialect, Hebei dialect, Gansu dialect, Shandong dialect, Taiyuan dialect; Foreign languages ​​support English, Japanese, Korean, Spanish, Vietnamese, Russian, French; even supports Tibetan and Uyghur ethnic minorities.

Next, let’s measure the conversion and recording effect of Xunfei Smart Recording Pen SR502. First of all, in order to test the accuracy of the offline transposition speed and text recognition of the SR502 of Xunfei smart recording pen. The speed of speaking is recording a paragraph, and the transliteration speed and accuracy of the intuitively seen from the test are very satisfactory.

Although it is not completely synchronized, there is no obvious delay. In terms of accuracy, because everyone’s speech may be more or less unclear and the pronunciation may be inaccurate, so there will be some errors in the transliteration, but the overall transfer will be transferred. The writing rate is high. For the place where the transliteration is wrong, we can modify it on the mobile app or the computer after uploading the cloud space, which is very convenient.

Sino -British mutual translation is definitely a great weapon. Like I like to watch some foreign bloggers’ evaluation videos, I used to see most of them relying on guessing. With Xunfei Smart Recording Pen SR502, I opened the side translation while watching it. , Basically, you can see the content of Sino -British mutual translation in real time.

For outdoor interviews and shooting videos, I use SR502 to shoot VLOG short videos. First of all, the sound quality and recording clarity are very high levels. A.I. Smart pickup and noise reduction technologies filtered out the sounds of whistle and passers -by. It is very accurate to generate the accuracy. Applying to the interview scene, the video interview will be more intuitive and vivid than SR501’s separate recording interviews.

In the conference record, SR502 can intelligently mark the spokesperson, filter off the non -human voice and silent clips to facilitate the editing in the later period. While recording, you can also use the OCR function. The pictures taken can be transferred to the text. Some important materials in the meeting are transferred together. In the later period, the minutes of the meeting are very efficient to avoid omissions.
