"Siri" also knows Sichuan dialect.

If you have an iphone in your hand, at the same time you will also speak a authentic Sichuan dialect, may wish to pick up your iphone with authentic Sichuan dialect to Siri said: "Rest assured Bahan is absolutely authentic", if it is from the United States Siri, it must not understand, although it can understand Cantonese. In real life, not only Siri, the market all the voice helper products, almost do not understand Sichuan dialect. However, this phenomenon will soon improve the hkust, the company has released the Sichuan dialect speech recognition technology.

At present, there are few companies doing dialect recognition technology in China, the biggest reason is that there are too many kinds of dialects in China, if we want to do dialect recognition technology, we need to establish different recognition models, and the dialect in various places lacks enough corpus, the speech recognition engine is insufficient, which leads to the low accuracy of recognition. So the number of people, or a wide range of dialects long to be resolved, Cantonese is a good example.

At Hkust, the solution is to develop a dialect speech recognition engine, which is suitable for dialect accents, through the technique of deep neural network. In the development of the engine at the same time with committee cooperation, collected enough dialect voice data to train the identification engine, through a large number of expected training, improve the accuracy of dialect recognition. Hkust said that they developed the Sichuan dialect speech recognition engine, recognition accuracy rate has exceeded 85%.

According to the Hkust News fly to reveal, Sichuan dialect speech recognition technology will be the first application of input method products, will soon be released to support Sichuan dialect speech input input method will be. Before the flying input method has been supported in Mandarin, English, Cantonese voice input. In addition to mobile phone input, dialect sound recognition technology still has a relatively rich use of the scene, for example, voice driving navigation, intelligent television, wearable equipment can be used, and even become a public platform for teaching, examination and evaluation, in addition, in listening to Beijing opera, Sichuan Opera, Kunqu Opera, Huangmei Opera and other dramas, to provide Mandarin meaning "translation" ......

Although not as universal as Mandarin, Sichuan dialect always has a very unique charm. And according to incomplete statistics, about 120 million people around the world say Sichuan dialect, is a very large group. And with the popularization of intelligent voice technology, it is very unscientific to let the students in Sichuan speak Mandarin before they can enjoy it. Therefore, the development of Sichuan dialect speech recognition technology is more real.

In addition to the Sichuan dialect, the hkust is developing the north-east, Shanghainese and other dialects of speech recognition technology will be released in the year.
