But it is also a mature business and the population is shrinking. SoftBank has a quarter of the market, trailing NTT DoCoMo and au.

但是这也是一个成熟的业务且人口在下降。软银占有四分之一的市场份额，紧随NTT DoCoMo和au其后。

For example, although the NTT DoCoMo phone-call translator is fast and easy to use, it struggles—even though it, too, uses a neural network—with anything more demanding than pleasantries.

例如，虽然NTT DoCoMo的电话翻译快捷易用，但任何比客套话复杂的句子都会让它难于应对――即使它也使用了神经网络。
