On August 28, 2019, Sogou launched the upgraded AI recording pen C1 pro. In the following three days, the stock price continued to rise, and the capital market and investors also recognized Sogou's increasing code in AI recording pen.

What kind of magic does a little recording pen have?


The changed recording pen industry

Influenced by factors such as single function and easy to be replaced by smart phones, the supply of traditional recording pens has always exceeded the demand, and the annual compound growth rate of output has been declining year by year. In the face of this situation, recording pen manufacturers are also constantly looking for new growth points, trying to break through the ceiling of industry scale.

In March 2018, Sogou launched an intelligent translation recording pen. A year later, Sogou released the AI recording pen C1, which is mainly used for recording and transcribing, and soon took the first place in the total sales volume of single products of several mainstream e-commerce platforms.

With the increasing number of users, Sogou has obtained clearer user portraits: 60% of users record more than three times a week; 41% of users record more than 10 minutes a week; business meetings, internal enterprise training and reporter interviews are three high-frequency use scenarios.

Homogeneous products can only fight price war and solve unsatisfied demand to expand new market. With the introduction of artificial intelligence technology, the traditional recording pen industry is full of new vitality.

On the day of the C1 Pro recording, the search partners and patriots, Newman, SONY recording pen and other partners set up the AI innovation alliance, and opened the Sogou transfer, simultaneous interpreting and other value-added services. In Sogou's view, the upgrading of business model can only be promoted by transforming the whole industry from the inferior competition of cost reduction to the combination of software and hardware services.

Industry insiders also said that the artificial intelligence recording pen, which meets more demands of consumers, will drive the industry to rebound.


Behind the AI recording pen

It is the product orientation ability that touches the demand test, and technical support is indispensable to meet the demand.

The first step to ensure the quality of transcribing is to obtain clear voice. In addition to the hardware support of the dual microphone array, purevoice AI noise reduction algorithm developed by Sogou can deal with the noise such as ambient sound, optimize the indoor reverberation and other problems, and effectively enhance the sound pickup effect of the target sound source.

As early as 2011, Sogou has been engaged in speech recognition, using industry-leading deep learning methods to solve this problem. Among them, the end-to-end acoustic model and neural network language model based on DTSS (deep transformer based sequence to sequence model) effectively improve the effect and experience of Sogou speech recognition. It is said that the accuracy rate of C1 Pro recording pen is 97% within 0.3m and 94% within 2m.

More than that, Sogou's translation system won the international top oral machine translation competition iwslt in October 2018. In January 2019, the research team of Sogou search artificial intelligence won the championship in coqa, a dialogue machine reading comprehension challenge, and refreshed all evaluation indexes.

The top technology not only makes AI recording pen a reality, but also gives birth to the artificial intelligence product matrix of Sogou. It can act as an simultaneous interpreting treasure PRO, a child's safe candy cat watch, and a Sogou biography and Sogou division. The CES's software and hardware products are all based on Sogou's long-term accumulation of AI technology.


Past and present

As early as 2017, Sogou repeatedly stressed the importance of artificial intelligence for the future development of the company in its IPO prospectus, saying that artificial intelligence is the key driving force of intelligent hardware.

In an internal letter released a year ago, Sogou CEO Wang Xiaochuan not only used a series of data to prove the correctness of Sogou's shift to artificial intelligence, but also said that he would invest more money around artificial intelligence, strengthen the accumulation and exploration of artificial intelligence technology with language as the core, and help users express and obtain information in more scenes.

Starting with search and gaining popularity with input method, why is today's Sogou on the road of artificial intelligence?

The AI path of Sogou is very clear. It takes language as the core, making human-computer interaction more natural and machine more intelligent.

From browser, search, input method, to AI technology supporting intelligent hardware, where will Sogou go next?

Time will give us the answer.
