IMAGINE if there was a device that could do everything for you – wake you up every morning, chat with you and type your e-mails.

The piece of technology in question would be smart, able to tell you about the weather and where the nearest restaurants are.

The good thing is you no longer need to wonder, because something like this already exists. And its name is Siri.

Siri is a voice recognition application designed for Apple products and the concept has been around for almost a year.

When Siri first came out it could only speak English, but now it has “learned” lots of new languages, including Chinese, Cantonese and Taiwanese, reported The Wall Street Journal. So, you can give it orders in your mother tongue.

But how could a cell phone or a computer “hear” what you are saying and understand it? This is all because of voice recognition technology.

When you speak, your voice creates vibrations (振动) in the air – a bit like waves in the water when you throw a rock into the lake. The microphone receives the vibrations and the computer changes them into digital data that is then divided into many parts. They are analyzed one by one to see what pronunciations each part stands for. The computer then puts these pronunciations together into possible words according to its built-in dictionary.

But figuring out the words is far from enough; building words into meaningful sentences is the most difficult part. The computer has to compare what it hears to a large library of known phrases and sentences to determine what the user is saying.

However, people don’t always talk in the most standard way and sometimes make grammatical mistakes. This is why traditional voice recognition software always requires you to remember keywords and to speak in a certain way.

Fortunately, Siri isn’t like that. It’s not just “voice recognition”; it’s “natural language understanding (NLU)”. You can ask it things like “Do I need an umbrella today?” and it will know that you are asking about the weather, according to ABC News.

“The key thing is NLU – understanding what you mean and what you want,” Neil Grant from Nuance, a software company in the US, told The Guardian. “Historically, you had to learn a huge long list of commands . As NLU progresses, you can say what you want in a way that’s natural to you.”

小题1:What is the function of the first two paragraphs?

A．To show that invention usually results from need.

B．To clear doubts about voice recognition technology.

C．To introduce something that offers these helpful services.

D．To show how the voice recognition works.小题2:Which step is the most complicated in the process of voice recognition according to the article?

A．Changing the received vibrations into digital data.

B．Analyzing the digital data to see what pronunciations it represents.

C．Putting the pronunciations together into possible words.

D．Figuring out meaningful sentences based on the words.小题3:How can you get Siri to respond according to the article?

A．You can speak in a natural way as you would to a person.

B．You can only speak English and Chinese.

C．You have to say things in a certain way.

D．You have to remember keywords and speak specific commands.小题4:What can be concluded from the article?

A．Siri can record and save what you say frequently into a computer dictionary.

B．Siri will fail to understand what you say if you make grammatical mistakes.

C．The biggest advantage of Siri is that it’s NLU is rather than just voice recognition.

D．Since first applied to Apple products a year ago, Siri has made great improvements.小题5:The text is mainly about ________.

A．the convenience of future life.

B．an introduction to the Apple products.

C．the working system of voice recognition

D．the introduction to Siri

    夏教授的建议

    当夏教授到京泰钢管公司参观访问时，接待并陪同他访问的年轻人孙晋给他留下了深刻 印象。孙晋是该公司人力资源经理助理，主要负责工作分析。公司专门指派了一位工业工程师到人力资源部门，协助孙晋进行工作设计。夏教授也曾被人力资源经理聘来研究该公司的工作分析体系，并提出改进的建议。他曾在人力资源办公室与孙晋一起浏览了工作说明书的所有文件，并发现这些说明总体上是完整的，而且与所完成的工作是直接相关的。

    参观访问的第一站就是焊接分厂张岩副厂长的办公室。这是一间十几平方米的房间，位于厂房一楼，四周都装了玻璃窗。当孙晋走近时，张岩正站在办公室外。“您好，孙助理”，他说。“您好，张厂长，”孙晋说，“这是夏教授。我们能看一看您的工作说明书并跟您聊一会儿吗当然”，张岩说着打开了门，“进来吧，请坐。我就把它们拿来。”从他们坐的地方恰好能看到工作现场的工人。在他们查阅每项工作说明书时，都有可能观察到工人实际中的工作。张岩很熟悉每项工作。“这儿的工作说明书是怎样与业绩评价相联系的呢”夏教授问道。“是这样，”张岩答道，“我只是根据工作说明书中规定的项目来评估员工业绩，而这些项目是由具体的工作分析来决定的。用这些项目来评价业绩能使我在工作发生变化、以前的说明不再能够准确反映现有工作情况时，及时修改工作说明。孙助理已经为所有中层以上干部制定了培训计划，所以我们都了解工作分析、工作说明书和业绩评价之间的关系。我认为这是一个很好的系统。”

    孙晋和夏教授继续参观了工厂的其他几个生产区，发现了类似的情况。孙晋似乎与每个分厂厂长、车间主任以及他们拜访的三位总厂领导的关系都很好。当他们回到办公室时，夏教授正考虑着他将向厂长提出什么建议。

景泰公司工作分析的显著特点是什么？你认为夏教授应向厂长提交一份什么样的报告？
