Intelligent voice strikes Sogou voice input more than 190 million requests per day
Recently, Sogou announced the third quarter 2016 financial report. The financial report shows that the current increase in the number of voice function calls for Sogou input method has accelerated significantly. The daily frequency of voice input has more than doubled compared with a year ago, and the single-day voice request exceeded 190 million times.
As the first domestic company to deploy artificial intelligence technology, Sogou took the lead in realizing the leap from concept to landing products. Taking voice recognition as an example, as the country's largest voice input application, the accuracy of voice recognition of Sogou input method has been continuously improved. It has now exceeded 97% and the recognition speed has reached 400 words per minute.
It is understood that Sogou's speech recognition technology uses the most advanced end-to-end model in the industry, which technically better solves the problem of user's swallowing in the process of speaking quickly, and uses an active learning method in the training method. . Through the end-to-end model and hardware acceleration, the recognition speed of Sogou input method speech has been increased by 3 times, and the recognition error rate has been reduced by 30%, which greatly reduces the error rate caused by accents and noisy environments.
It is worth mentioning that, unlike the current voice input method that emphasizes recognition rate on the market, Sogou's voice input pays more attention to intelligent input. As we all know, no matter how high the recognition accuracy is, there will still be typos in voice input. In order to truly liberate your hands and achieve a more natural interaction, Sogou input method introduces an exclusive voice modification function that supports pure natural language to correct errors. For example, the user can say: change 'Chen' to Erdong 'Chen'. At the same time, with the help of the Sogou search engine's encyclopedia knowledge map, Sogou voice can better understand the user's expression in natural text communication. For example, after the user inputs “I want to eat†using voice, he can directly say “add Wudaokou to the backâ€, and it will be recognized as “I want to eat at Wudaokouâ€. It is understood that the function currently supports hundreds of error correction grammars and rich description methods such as replacement, insertion, and deletion. The modification success rate reaches 80%, which is equivalent to a further reduction of 80% in the error rate of speech recognition.
In the current hot background of the intelligent voice industry, Sogou voice can break through the traffic mark first, indicating that with the increasing acceptance of users, voice input has gradually become the mainstream input method and has become a new communication method for people. With its leading industry accuracy, highly user-friendly voice input and modification functions, Sogou voice input has been highly praised by users for its smart and convenient user experience. I believe that in the future, as the voice technology continues to mature, Sogou voice will continue Bring better experience and surprises to users, and its leading position in the industry will become more stable.
