Smart voice is strong, Sogou voice input, single-day request exceeded 190 million times
Recently, Sogou announced the third quarter 2016 financial report. The financial report shows that the number of voice function calls of the Sogou input method has increased significantly. The daily frequency of voice input has more than doubled from a year ago, and the single-day voice request has exceeded 190 million times.
As the first enterprise to deploy artificial intelligence technology in China, Sogou took the lead in realizing the leap from concept to landing products. Taking speech recognition as an example, as the first voice input application in China, the accuracy of speech recognition of Sogou input method has been continuously improved, currently over 97%, and the recognition speed has reached 400 words per minute.
It is understood that Sogou speech recognition technology uses the most advanced end-to-end model in the industry, technically better solves the problem of swallowing in the process of fast speech, and uses an active learning method in the training method. . Through the end-to-end model and hardware acceleration, Sogou input method speech recognition speed is increased by 3 times, recognition error rate is reduced by 30%, greatly reducing the error rate caused by accent and noisy environment.
It is worth mentioning that, unlike the current voice input method that emphasizes the recognition rate on the market, Sogou's voice input pays more attention to intelligent input. As we all know, the recognition accuracy is higher, and the voice input still has typo. In order to truly liberate both hands and achieve a more natural interaction, Sogou input method introduces an exclusive voice modification function that supports pure natural language for error correction. For example, the user can say: change 'Chen' to Erdong 'Chen'. At the same time, with the encyclopedia knowledge map of Sogou search engine, Sogou voice can better understand the user's expression in natural text communication. For example, after the user uses the voice input "I want to go to eat", you can directly say "add five crossings when you want to go", it will be recognized as "I want to go to Wudaokou to eat." It is understood that the function currently supports hundreds of error correction grammars and rich description methods such as replacement, insertion, deletion, etc., and the modification success rate reaches 80%, which is equivalent to a further 80% reduction in the error rate of speech recognition.
In the current fierce background of the intelligent voice industry, Sogou voice can take the lead in breaking through the traffic mark, indicating that with the increasing acceptance of users, voice input has gradually entered the mainstream input mode, becoming a new way of communication. Sogou voice input has won high praise from users with its accurate and user-friendly voice input and modification functions. It is believed that in the future, with the continuous maturity of voice technology, Sogou voice will continue to be Bringing users a better experience and surprises, its leading position in the industry will also become more stable.
