This is the VOA Special English Technology Report.
2
Smartphones, tablet computers, and e-readers have become a part of everyday life for many people.
3
They have also led to an explosion in the number of mobile applications.
4
There is an app for just about anything you can think of of,
5
and more and more apps are being created every day.
6
Robert DeNazi is a Hollywood movie producer.
7
He is perhaps best well known as the executive producer of Flight Plan,
8
the 2005 movie starring actress Jodie Foster.
9
His most recent claim to fame is as co-developer of a new app called VoiceCal.
10
It is a mobile calendar app that uses voice recognition software.
11
Users are able to enter appointments into their iPhone calendar without having to type in the information.
12
He said although he has a mobile phone,
13
he had to stop what he was doing to put things in his calendar.
14
In his words, it got to the point where I just wasn't using the calendar on my iPhone,
15
and neither was anybody else that I knew.
16
Robert DeNazi decided there had to be a better way.
17
So he teamed up with a friend who is a developer.
18
The two used voice recognition software from a company called Nuance to build VoiceCal.
19
He says when you use VoiceCal,
20
you can say any event you want to put into your calendar and it will appear there.
21
If you have two or more events to add to the calendar,
22
you separate them by using the word also.
23
Mr. DeNazi says all of this can be done hands-free.
24
In settings, you can make it fully automatic,
25
so I don't have to touch anything, he says.
26
Robert DeNazi says there is a great need for an app like VoiceCal among busy businessmen like himself.
27
He hopes the app will be successful over the long term.
28
He says, in the movie business,
29
you can do all the advertising in the world,
30
and that can get you a great opening weekend.
31
But if the movie's not good, it will die off.
32
So really, what supports a film,
33
just like what supports an app, is word of mouth.
34
Matt Kozlov is the head of a startup technology company called Moonshark in Los Angeles, California.
35
The company makes game apps for mobile devices.
36
It's an exploding marketplace right now, he says.
37
There are hundreds of millions of devices out there right now that we can reach.
38
Jennifer Lopez is helping Moonshark with a finger breakdancing game called DancePad.
39
The company is also working with film director John Woo on
40
an action game expected to be released at the end of this year.

43
Member countries of the International Criminal Court met in June in Kampala, Uganda.
44
They were there to examine the court's progress for the first time.
45
Observers, human rights activists, and civil society groups also attended the two-week review conference.
46
A treaty called the Rome Statute established the court in The Hague in the Netherlands in 2002.
47
The court can try people for genocide,
48
war crimes, and crimes against humanity when their own countries are unwilling or unable to.
49
The court was also given the right to try crimes of aggression,
50
although it never has.
51
This is partly because ICC members could not agree on how to define aggression.
52
In Kampala, they agreed on a compromise resolution.
53
It defines the crime in terms of acts by a political
54
or military leader against another state in violation of the United Nations Charter.
55
Invasions, attacks, and blockades could all be tried as acts of aggression.
56
So could letting another country use a state's territory for aggressive acts against a third state state.
57
The United Nations Security Council has the lead responsibility for deciding that an act of aggression has taken place.
58
But if the Council takes no action within six months,
59
the court might still be able to carry out an investigation.
60
pointed out that the agreement does not permit the court to punish aggression by non-member countries or their nationals.
61
Also, members could refuse to accept the court's right to try crimes of aggression.
62
ICC countries also agree to delay any action by the court on aggression until they re-examine the issue in seven years.
63
The International Criminal Court has yet to complete its first case involving any crime.
64
Eleven cases are currently before the court.
65
They include the case against Sudanese President Omar al-Bashir.
66
He is the first head of state to be charged by the ICC while in office.
67
Two years ago, the court found him guilty of war crimes in Darfur.
68
Last year, it ordered his arrest.
69
But Sudan rejects the ruling.
70
The ICC Review Conference took place even as the president was just sworn in for a new term.
71
111 countries are parties to the Rome Statute.
72
The United States is not among them,
73
but took part in Kampala as an observer.
74
Other countries that have not joined the court include China and Russia.
75
And that's the VOA Special English Development Group.

77
A few degrees can make a big difference when it comes to food storage.
78
Foods can go bad if they get too warm.
79
But for many of the world's poor,
80
finding a good way to keep food cool is difficult.
81
Refrigerators are costly and they need electricity.
82
spoiled food not only creates health risks but also economic losses.
83
Farmers lose money when they have to throw away products that they cannot sell quickly.
84
But in 1995, a teacher in northern Nigeria named Mohamed Baaba found a solution.
85
He developed the Pot in Pot Conservation Cooling System.
86
It uses two round containers made of clay.
87
A smaller pot is placed inside a larger one.
88
The space between the two pots is filled with wet sand.
89
The inner pot can be filled with fruit, vegetables, or drinks.
90
A wet cloth covers the whole cooling system.
91
Food stored in the smaller pot is kept from spoiling through a simple evaporation process.
92
Water in the sand between the two pots evaporates through the surface of the larger pot where drier outside air is moving.
93
The evaporation process creates a drop in temperature of several degrees.
94
This cools the inner pot and and helps keep food safe from harmful bacteria.
95
Some foods can be kept fresh this way for several weeks.
96
People throughout Nigeria began using the invention,
97
and it became popular with farmers in other African countries.
98
Mohamed Baaba personally financed the first 5,000 pot-in-pot systems for his own community and five villages nearby.
99
In 2000, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise.
100
This award recognizes people trying to develop projects aimed at improving human knowledge and well-being.
101
A committee considers projects in science and medicine
102

103
and cultural history winners receive financial assistance to help developed
104
and extend their projects the awards are given every two years the next awards will be presented in late

From VOA Learning English, this is the Technology Report.
111
High-tech companies are developing the next generation of products that will help us drive cars,
112
do our shopping, and even care for our children.
113
The technology company Intel recently held a demonstration of some of its new devices in San Francisco.
114
One device measured how alert a driver was.
115
Sensors connected to the driver's head measured brain activity.
116
Cameras placed on the car's dashboard measured eye movement.
117
Justin Ratner works at Intel Labs.
118
He says the devices measure how much of the brain is occupied while the person is driving.
119
Devices like these, he says, will make driving safer.
120
Another experimental intel technology links cars electronically to help prevent crashes.
121
When the driver of the car in front signals a turn or slows down,
122
an alert message is sent to the car in back.
123
There was also a demonstration of a virtual computer.
124
The computer was projected onto the table from a controller hidden in a flower pot.
125
Sensors read the movements of the user's hands,
126
so there was no need for a mouse or other handheld device.
127
This technology could be used in everyday situations.
128
At a market, sensors and computer chips placed in products could help shoppers find the items they want to buy.
129
For example, the technology could help them avoid foods that could cause an allergic reaction.
130
Cameras and sensors are already available to help parents watch their children.
131
In the future, other equipment will monitor a baby's health and mood.
132
And security systems are being improved and simplified with face recognition software instead of complicated passwords.

135
Sony officials held a news conference in early May in Tokyo.
136
They apologized for the theft of personal information from millions of users of the company's online services.
137
targeted Sony's PlayStation Network, Sony Online Entertainment, and Curiosity Music Systems.
138
In all, Sony says information may have been stolen from more than 100 million accounts.
139
The data includes information like names,
140
addresses, phone numbers, and birthdates.
141
In some cases, even credit and debit card numbers may have been stolen.
142
The United States Federal Bureau of Investigation is looking into the cyber attacks.
143
Sony shut down its PlayStation network on April 20th.
144
The company is being criticized for not telling its users about the stolen information until a week later.
145
Sony has also been criticized for not making its accounts more secure by encrypting the data.
146
Sony officials say they have now taken steps to improve security.
147
Peter Warren is chairman of the Cybersecurity Research Institute in London.
148
His group studies technology crimes and their effects on our computer-dependent world.
149
Mr. Warren points out that what happened at Sony is not rare.
150
We've seen a number of very large companies that have suffered some tremendously embarrassing losses of data.
151
The problem, he says, is that there is far more interest in developing technology than in keeping it safe.
152
As he puts it, lots
153
and lots of people are being allowed to connect a lot of technology up before it's really been particularly well tested.
154
Peter Warren also points out that many people have a false sense of security online.
155
On the Internet, he says,
156
they seem to be so blindly trusting of anybody and of any website,
157
no matter how suspicious it may look.
158
His message to users is simple.
159
Try to be more careful on websites.
160
He says, the internet is just like any other street,
161
and there are some twists and turns that can take you into some very, very unsavory places.

Hướng dẫn Shadowing từng bước
Để cải thiện khả năng phát âm tiếng anh chuẩn và luyện nghe nói qua video, việc thực hiện shadowing với video này có thể rất hiệu quả. Dưới đây là từng bước bạn có thể làm theo:
- Xem video lần đầu tiên: Nghe từng câu và tập trung vào ngữ điệu của người nói.
- Nghe kỹ từng câu: Dừng lại sau mỗi câu hoặc phần nhỏ, ghi chú lại những từ khó và cách phát âm của chúng.
- Thực hành phát âm: Lặp lại theo từng câu, cố gắng bắt chước cách nói của diễn giả. Sử dụng phương pháp shadowspeak để giúp bạn dễ dàng bắt chước ngữ điệu và nhịp điệu.
- Đối chiếu: Nghe lại phần mình đã phát âm và so sánh với video để cải thiện những điểm còn yếu.
- Lặp lại toàn bộ video: Khi bạn cảm thấy tự tin, hãy thực hiện toàn bộ video mà không dừng. Đây là cách tốt nhất để luyện nghe nói hiệu quả.
Với sự kết hợp giữa phát âm tiếng anh chuẩn và luyện nghe nói qua video, bạn sẽ nhanh chóng nâng cao kỹ năng giao tiếp của mình. Hãy thường xuyên quay lại các video và tập luyện để duy trì và phát triển khả năng ngôn ngữ của bạn!
Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
