翻译人员: Jenny Yang 校对人员: Bear Jin

Imagine if you could record your life --

想象一下如果你能记录你的生活--

everything you said, everything you did,

你说的一切，做的一切

available in a perfect memory store at your fingertips,

就存储在一个完美的你触手可及的记忆库

so you could go back

你可以回到过去

and find memorable moments and relive them,

找寻那难忘一刻回顾这一切

or sift through traces of time

或者追寻时间的轨迹

and discover patterns in your own life

发现在属于你自己的生活模式

that previously had gone undiscovered.

那种以前没有发现的规律

Well that's exactly the journey

而那就是我们全家

that my family began

5年半前开始的

five and a half years ago.

家庭旅程

This is my wife and collaborator, Rupal.

这是我妻子和合作者， 鲁泊尔

And on this day, at this moment,

在这一天，从这一刻

we walked into the house with our first child,

我们带着我们第一个孩子走进了这个家

our beautiful baby boy.

我们美丽的儿子

And we walked into a house

我们走进了一个

with a very special home video recording system.

安装了特殊的家庭摄像系统的家

(Video) Man: Okay.

(录像) 男人：好

Deb Roy: This moment

戴·罗伊: 这一刻

and thousands of other moments special for us

和其他千万的我们的特殊时刻

were captured in our home

在我们家中被捕捉下来

because in every room in the house,

因为这个房子的每个屋子

if you looked up, you'd see a camera and a microphone,

如果你仰头看，你都可以看见一个摄像机和话筒

and if you looked down,

而你望下看

you'd get this bird's-eye view of the room.

你可以俯视整个房间

Here's our living room,

这是我们的客厅

the baby bedroom,

这是婴儿的房间

kitchen, dining room

厨房，餐厅

and the rest of the house.

这是其余的地方

And all of these fed into a disc array

这些都被装进了一排

that was designed for a continuous capture.

为持续拍摄设计的光盘中

So here we are flying through a day in our home

这里我们飞快地经历一遍我们家庭的一天

as we move from sunlit morning

我们从太阳初升的早晨

through incandescent evening

到亮起电灯的夜晚

and, finally, lights out for the day.

最后， 熄灯就寝

Over the course of three years,

历经3年的时间

we recorded eight to 10 hours a day,

我们每天记录8到10个小时

amassing roughly a quarter-million hours

积累了大约25万小时

of multi-track audio and video.

的多轨音频和视频资料

So you're looking at a piece of what is by far

所以你现在看到的是有史以来

the largest home video collection ever made.

最大的家庭录相集

(Laughter)

(笑声)

And what this data represents

从个人的角度而言，

for our family at a personal level,

这些代表了我们家庭的资料

the impact has already been immense,

已经产生了巨大的影响

and we're still learning its value.

我们还在继续学习其中的价值

Countless moments

无数的时刻

of unsolicited natural moments, not posed moments,

无预兆的，不造作的自然时刻

are captured there,

都记录在这里

and we're starting to learn how to discover them and find them.

我们正开始学习怎样发现和寻找它们

But there's also a scientific reason that drove this project,

而促使这个项目还有一个科学的原因

which was to use this natural longitudinal data

便是用这些纵向记录的数据

to understand the process

去了解一个

of how a child learns language --

孩子是怎样学习语言的--

that child being my son.

这个孩子是我的儿子

And so with many privacy provisions put in place

所以在设置了隐私保护的条件下

to protect everyone who was recorded in the data,

每个被记录到的人物都得到保护

we made elements of the data available

我们对我们信任的麻省理工研究团队

to my trusted research team at MIT

公开了部分数据

so we could start teasing apart patterns

因此我们可以从这个巨大的

in this massive data set,

数据资料中排除出一些多余的模式

trying to understand the influence of social environments

以此来试图理解社会环境

on language acquisition.

对语言形成的影响

So we're looking here

所以我们在这里看到

at one of the first things we started to do.

我们所做的第一件事情

This is my wife and I cooking breakfast in the kitchen,

这是我的妻子和我在厨房做早餐

and as we move through space and through time,

随着时间的流逝地点的变化

a very everyday pattern of life in the kitchen.

这是厨房里日常生活的轨迹

In order to convert

为了转换

this opaque, 90,000 hours of video

这个9万小时的录相

into something that we could start to see,

将它变成我们能识辨的东西

we use motion analysis to pull out,

我们用行动分析来抽取

as we move through space and through time,

我们在时空的移动

what we call space-time worms.

我们称之为 时空虫

And this has become part of our toolkit

这个成为了我们工具的一部分

for being able to look and see

用来观察和辨识

where the activities are in the data,

数据中的各种活动

and with it, trace the pattern of, in particular,

再利用这个办法，去追踪模型，特别是

where my son moved throughout the home,

我儿子在家去过哪些地方

so that we could focus our transcription efforts,

使得我们能够聚焦解读

all of the speech environment around my son --

我儿子学习语言的语境

all of the words that he heard from myself, my wife, our nanny,

他从我，我妻子和保姆那里听到的所有词汇

and over time, the words he began to produce.

渐渐的，他开始使用的词汇

So with that technology and that data

因此通过技术和数据

and the ability to, with machine assistance,

在机器的协助下

transcribe speech,

录制下对话

we've now transcribed

我们现在已经完成了

well over seven million words of our home transcripts.

超过7万字的家庭言谈的记录

And with that, let me take you now

现在，让我带你们

for a first tour into the data.

进入这些数据的第一个旅行

So you've all, I'm sure,

我相信，你们大家都

seen time-lapse videos

看过时间推移的影片

where a flower will blossom as you accelerate time.

加快时间的推移你可以看见花朵盛开

I'd like you to now experience

现在我让你们看看

the blossoming of a speech form.

语言的花朵是怎样绽放的

My son, soon after his first birthday,

我的儿子，在他的第一个生日后

would say "gaga" to mean water.

会说“gaga“来指水

And over the course of the next half-year,

在这之后的半年里

he slowly learned to approximate

他渐渐地学会了

the proper adult form, "water."

成年人说的正确的“水”

So we're going to cruise through half a year

我们现在来用40秒时间

in about 40 seconds.

快速浏览这半年

No video here,

没有影象

so you can focus on the sound, the acoustics,

所以你们可以专注听声音，声学上的

of a new kind of trajectory:

这种新的轨迹变化

gaga to water.

从“Gaga"到"Water"

(Audio) Baby: Gagagagagaga

(声音)婴儿：Gagagagagaga

Gaga gaga gaga

Gaga gaga gaga

guga guga guga

guga guga guga

wada gaga gaga guga gaga

wada gaga gaga guga gaga

wader guga guga

wader guga guga

water water water

water water water

water water water

water water water

water water

water water

water.

water

DR: He sure nailed it, didn't he.

戴·罗伊: 他学会了啊，不是吗？

(Applause)

(掌声)

So he didn't just learn water.

而他并不只是学会了水

Over the course of the 24 months,

在24个月里

the first two years that we really focused on,

在最初的2年里，这才是我真正关注的

this is a map of every word he learned in chronological order.

这里有一张图按照时序列出了他所学到的词汇

And because we have full transcripts,

因为我们有全部的记录

we've identified each of the 503 words

我们为他到两岁前学会的503个单词

that he learned to produce by his second birthday.

都做了辨认和分析

He was an early talker.

他算是说话早的

And so we started to analyze why.

所以我们开始分析其原因

Why were certain words born before others?

为什么有些词他学得早

This is one of the first results

这是其中的一个研究结果

that came out of our study a little over a year ago

是一年多前出来的

that really surprised us.

让我们很吃惊

The way to interpret this apparently simple graph

解读这张看似简单的图表的方式

is, on the vertical is an indication

是横坐标表示

of how complex caregiver utterances are

照顾者的话语复杂程度

based on the length of utterances.

基于话语的长度

And the [horizontal] axis is time.

纵坐标代表了时间(演讲者口误)

And all of the data,

所有的数据

we aligned based on the following idea:

我们都用下述的方法排列：

Every time my son would learn a word,

每次我们发现儿子学了一个新的词

we would trace back and look at all of the language he heard

我们就会回溯他听过的这个词的

that contained that word.

所有的语言记录

And we would plot the relative length of the utterances.

然后我们绘制这些语言的长度

And what we found was this curious phenomena,

我们发现了一个奇特的现象

that caregiver speech would systematically dip to a minimum,

照顾者的讲话会系统地将语言简化

making language as simple as possible,

简化到最简单的程度

and then slowly ascend back up in complexity.

然后渐渐地回升到更复杂的句子

And the amazing thing was

而惊奇的事是

that bounce, that dip,

这种回升和下降

lined up almost precisely

正好精确的

with when each word was born --

吻合了每个词的诞生过程--

word after word, systematically.

一个词接一个词，很有系统规律

So it appears that all three primary caregivers --

似乎三个主要的照顾他的人

myself, my wife and our nanny --

我，我妻子，和我们的保姆--

were systematically and, I would think, subconsciously

都是有系统的，我想，也是下意识的

restructuring our language

重新构建我们的用语

to meet him at the birth of a word

去迎合他的新的词汇的诞生

and bring him gently into more complex language.

带他渐渐学习更为复杂的语言

And the implications of this -- there are many,

这其中蕴含的--有很多意义

but one I just want to point out,

但是我想指出的其中的一个

is that there must be amazing feedback loops.

就是这个过程中必定包涵了一个惊人的反馈循环

Of course, my son is learning

当然，我的儿子是

from his linguistic environment,

在他的语言环境中学习

but the environment is learning from him.

但是那个环境也在向他学习

That environment, people, are in these tight feedback loops

环境，人，都在这个紧密的反馈循环中

and creating a kind of scaffolding

并建立了一种类似脚手架的互相支撑关系

that has not been noticed until now.

这是之前没有被注意到的

But that's looking at the speech context.

这是关注讲话的语境来看

What about the visual context?

若是从视觉环境来看呢？

We're not looking at --

我们现在看到的是

think of this as a dollhouse cutaway of our house.

想象这是用我们家做样板做的洋娃娃屋

We've taken those circular fish-eye lens cameras,

我们使用环状鱼眼睛摄像机

and we've done some optical correction,

我们还做了些光学修正

and then we can bring it into three-dimensional life.

然后我们就可以把它做成三维录像

So welcome to my home.

欢迎到我家来

This is a moment,

这是其中的一刻

one moment captured across multiple cameras.

通过几个录相机拍下的同一时刻

The reason we did this is to create the ultimate memory machine,

我们这样做是为了创造出终极的记忆机器

where you can go back and interactively fly around

你可以用互动的方式前后快速搜寻

and then breathe video-life into this system.

然后用这系统体验录像生活

What I'm going to do

我要做的是

is give you an accelerated view of 30 minutes,

是给你们看一段压缩了30分钟的速放录像

again, of just life in the living room.

这次也是在客厅

That's me and my son on the floor.

这是我和我儿子在地上

And there's video analytics

这是影片分析

that are tracking our movements.

跟踪我们的移动

My son is leaving red ink. I am leaving green ink.

我儿子的留下了红色的轨迹，我的是绿色的

We're now on the couch,

我们在沙发上

looking out through the window at cars passing by.

看着窗外汽车开过

And finally, my son playing in a walking toy by himself.

最后，我儿子自己玩他的学步玩具

Now we freeze the action, 30 minutes,

现在定格，30分钟

we turn time into the vertical axis,

我们将时间放到垂直轴上

and we open up for a view

然后我们打开

of these interaction traces we've just left behind.

刚才留下的互动的轨迹

And we see these amazing structures --

我们看见令人惊讶的结构

these little knots of two colors of thread

这是两种颜色的小结点

we call "social hot spots."

我们把它称为社交热点

The spiral thread

那些螺旋线

we call a "solo hot spot."

我们称为单一热点

And we think that these affect the way language is learned.

我们觉得这个影响语言学习

What we'd like to do

我们要做的是

is start understanding

是开始去了解

the interaction between these patterns

这些模式与我儿子接触的

and the language that my son is exposed to

语言间的关系

to see if we can predict

看我们是否能预测

how the structure of when words are heard

什么时候听到怎样的单词结构

affects when they're learned --

会影响到什么时候学会字词

so in other words, the relationship

换句话说，就是

between words and what they're about in the world.

词汇和他们所表示的世界的关系

So here's how we're approaching this.

这是我们的解读方法

In this video,

在这个录像中

again, my son is being traced out.

同样是跟踪我的儿子

He's leaving red ink behind.

他留下了红色的轨迹

And there's our nanny by the door.

我们的保姆在门边

(Video) Nanny: You want water? (Baby: Aaaa.)

(录像)保姆：你要喝水妈？ (宝宝：Aaaa)

Nanny: All right. (Baby: Aaaa.)

保姆：好。(宝宝：Aaaa)

DR: She offers water,

戴·罗伊:她给他水

and off go the two worms

然后两条时空虫

over to the kitchen to get water.

开始移动到厨房拿水

And what we've done is use the word "water"

同时我们所做的就和“水”这个词

to tag that moment, that bit of activity.

联系上了，随着一些动作

And now we take the power of data

然后我们用数据的力量

and take every time my son

每次我儿子

ever heard the word water

听到水这个字

and the context he saw it in,

以及他看见的情景

and we use it to penetrate through the video

我们利用这些来分析整个影片

and find every activity trace

找到每个跟

that co-occurred with an instance of water.

“水”字出现时发生的活动

And what this data leaves in its wake

这个数据勾勒出了

is a landscape.

这么一幅风景

We call these wordscapes.

我们把这个叫做 词景

This is the wordscape for the word water,

这是水字的词景

and you can see most of the action is in the kitchen.

你可以看见大多数行动是在厨房

That's where those big peaks are over to the left.

就是左边的这些高峰

And just for contrast, we can do this with any word.

相对，你也可以为其他词汇勾勒词景

We can take the word "bye"

比如“goog bye”(再见)里的

as in "good bye."

”bye"字

And we're now zoomed in over the entrance to the house.

我们放大到房子大门口附近

And we look, and we find, as you would expect,

我们看到，我们发现，你也会想到

a contrast in the landscape

一幅相对的景象

where the word "bye" occurs much more in a structured way.

在那儿你看到“bye“高频率出现的结构

So we're using these structures

我们用这些结构

to start predicting

开始预言

the order of language acquisition,

学会语言的顺序

and that's ongoing work now.

这是在持续进行的工作

In my lab, which we're peering into now, at MIT --

在我麻省理工学院的研究室-就是现在看到

this is at the media lab.

那是在媒体实验室里

This has become my favorite way

这成了我最喜欢的空间

of videographing just about any space.

视频制图方法

Three of the key people in this project,

这个项目的关键人物都在

Philip DeCamp, Rony Kubat and Brandon Roy are pictured here.

就是图片里的菲利普·迪坎普, 罗尼·库巴特和布兰登·罗伊

Philip has been a close collaborator

菲利普是一个密切的合作者

on all the visualizations you're seeing.

你们看到的视觉化功能就是他负责的

And Michael Fleischman

还有麦克尔·菲莱舍曼

was another Ph.D. student in my lab

是我实验室的另一个博士生

who worked with me on this home video analysis,

和我一起做了家庭视频的分析

and he made the following observation:

是他发表了以下的观点：

that "just the way that we're analyzing

“我们分析

how language connects to events

语言如何于事件相关

which provide common ground for language,

这是语言的共同的基础

that same idea we can take out of your home, Deb,

我们可以把同样的思路带出你的家，戴

and we can apply it to the world of public media."

我们可以把它用到公共媒体上”

And so our effort took an unexpected turn.

所以我们的研究有了个意想不到的转折

Think of mass media

想到大众媒体

as providing common ground

提供共同的基础

and you have the recipe

你就可以把我们的方法

for taking this idea to a whole new place.

运用到一个崭新的地方

We've started analyzing television content

我们开始分析电视内容

using the same principles --

用同样的原则--

analyzing event structure of a TV signal --

分析一个电视信号的事件结构--

episodes of shows,

电视剧集

commercials,

广告

all of the components that make up the event structure.

所有的组成事件结构的成分

And we're now, with satellite dishes, pulling and analyzing

我们现在， 通过卫星电视，抽出分析了

a good part of all the TV being watched in the United States.

在美国高收视率的电视节目

And you don't have to now go and instrument living rooms with microphones

你不再需要把麦克风装在起居室里来

to get people's conversations,

记录人们的对话

you just tune into publicly available social media feeds.

你只要去听公开的社交媒体讯息就可以了

So we're pulling in

我们每个月抽出

about three billion comments a month,

大概30亿个评论

and then the magic happens.

奇迹发生了

You have the event structure,

这中间可以找到事件结构

the common ground that the words are about,

这些词汇的共同基础

coming out of the television feeds;

那些从这次电视讯息里透露出的反馈

you've got the conversations

你得到有关这些

that are about those topics;

话题的对话

and through semantic analysis --

通过语意分析

and this is actually real data you're looking at

你们看到的这个是根据我们的数据处理过后

from our data processing --

的真实的数据结果--

each yellow line is showing a link being made

每条黄线显示一个链接

between a comment in the wild

连接着外界的评论

and a piece of event structure coming out of the television signal.

和电视信号发出的事件结构间的关系

And the same idea now

这都是用同样的思路

can be built up.

构建起来的

And we get this wordscape,

我们得到了这个词汇背景

except now words are not assembled in my living room.

不过现在词汇不是从我的客厅里来的

Instead, the context, the common ground activities,

取而代之的情境，共同基础活动

are the content on television that's driving the conversations.

是电视内容带动的对话

And what we're seeing here, these skyscrapers now,

我们现在看到的这些高耸的结构

are commentary

都是电视评论

that are linked to content on television.

它们跟电视上播放的内容联系着

Same concept,

同样的概念

but looking at communication dynamics

但是你们看见的是它在不同的领域

in a very different sphere.

展现的交流动态

And so fundamentally, rather than, for example,

从根本上，而不是，比如

measuring content based on how many people are watching,

根据收视率衡量内容

this gives us the basic data

这个给了我们观察这些

for looking at engagement properties of content.

内容参与性的最基本的资料

And just like we can look at feedback cycles

就跟我们可以看见家里的

and dynamics in a family,

反馈循环和互动一样

we can now open up the same concepts

我们现在可以利用同样的构想

and look at much larger groups of people.

来观察更大的群体

This is a subset of data from our database --

这是我们资料库里的一个子集

just 50,000 out of several million --

只是几百万信息中的5万条

and the social graph that connects them

社交图是和公开资缘

through publicly available sources.

来自于对大众公开的来源

And if you put them on one plain,

如果你把它们放到平面上

a second plain is where the content lives.

第二个平面是内容活跃的地方

So we have the programs

于是我们有了节目

and the sporting events

体育活动

and the commercials,

广告

and all of the link structures that tie them together

所有的链接结构将它们连在一起

make a content graph.

形成了内容图表

And then the important third dimension.

然后是重要的第三个面向

Each of the links that you're seeing rendered here

大家在这里看到的每个连接

is an actual connection made

是一段内容和有些人评论

between something someone said

和有些人评论

and a piece of content.

间构成的真实联系

And there are, again, now tens of millions of these links

这里的几千万条链

that give us the connective tissue of social graphs

让我们看见了社交图表中的关联组织

and how they relate to content.

和它们跟内容的关系

And we can now start to probe the structure

于是我们可以用有趣的办法来

in interesting ways.

探索这个结构

So if we, for example, trace the path

所以，比如，我们跟踪

of one piece of content

某个内容的发展途经

that drives someone to comment on it,

这促使有人对此发表评论

and then we follow where that comment goes,

然后我们跟踪这些评论的去向

and then look at the entire social graph that becomes activated

然后观察整个活跃的社交图

and then trace back to see the relationship

然后又回头追踪查看那个社交图

between that social graph and content,

和内容之间的关系

a very interesting structure becomes visible.

于是显现出一个非常有趣的结构

We call this a co-viewing clique,

我们称之为 共视团体

a virtual living room if you will.

你可以把它当成一个虚拟的客厅

And there are fascinating dynamics at play.

这里头上演着引人注目的戏剧

It's not one way.

它不是单向的

A piece of content, an event, causes someone to talk.

一个内容，一个事件促使某人发表了意见

They talk to other people.

他们和其他人对话

That drives tune-in behavior back into mass media,

就驱动了大众传媒的收视行为

and you have these cycles

于是出现了这样的循环

that drive the overall behavior.

驱动了整体的收视行为

Another example -- very different --

另一个例子--情况很不同--

another actual person in our database --

我们的资料库里有一位人士--

and we're finding at least hundreds, if not thousands, of these.

其实我们可以找到成千上百个例子

We've given this person a name.

我们给这个人一个名字

This is a pro-amateur, or pro-am media critic

这是一个专业的媒体评论员

who has this high fan-out rate.

有很多粉丝

So a lot of people are following this person -- very influential --

很多人都追随他 -- 很有影响力--

and they have a propensity to talk about what's on TV.

他们很喜欢讨论电视上在播的东西

So this person is a key link

于是这个人就是一个关键的链接

in connecting mass media and social media together.

将大众媒体和社交媒体联系在了一起

One last example from this data:

这份资料的最后一个例子是：

Sometimes it's actually a piece of content that is special.

有时确实是一件特别的内容

So if we go and look at this piece of content,

如果我们回顾这个内容

President Obama's State of the Union address

几个星期前的欧巴马总统

from just a few weeks ago,

国情咨文演讲

and look at what we find in this same data set,

再来看看我们在这组资料中发现些什么

at the same scale,

用同样的尺度来衡量

the engagement properties of this piece of content

这个内容的可参与属性

are truly remarkable.

真的是很神奇的

A nation exploding in conversation

整个国家顿时同步

in real time

爆发了谈话

in response to what's on the broadcast.

是针对广播的东西

And of course, through all of these lines

当然，通过这些线路

are flowing unstructured language.

涌现出了结构的语言

We can X-ray

我们可以在 社交点 上

and get a real-time pulse of a nation,

感受一下这个国家即时的动脉

real-time sense

即时的感受

of the social reactions in the different circuits in the social graph

不同的社会圈的社会反应被内容所激活

being activated by content.

都展示在社会图表上

So, to summarize, the idea is this:

所以， 总结来说，观点是：

As our world becomes increasingly instrumented

当我们的世界变得越来越工具化

and we have the capabilities

我们有能力

to collect and connect the dots

搜集和链接一个一个小点

between what people are saying

将人们的话语

and the context they're saying it in,

和他们说这些话时所处得环境联系起来

what's emerging is an ability

那么呈现的将是洞悉

to see new social structures and dynamics

社会结构和社交动态的新视野

that have previously not been seen.

那是以前我们没有看见过的

It's like building a microscope or telescope

这好像是造一个显微镜或者望远镜

and revealing new structures

展示了我们交流和行为间

about our own behavior around communication.

的新结构

And I think the implications here are profound,

我觉得其意义是深远的

whether it's for science,

无论是对科学而言

for commerce, for government,

还是对商业，政府而言

or perhaps most of all,

或许更重要的是

for us as individuals.

对我们每个人而言

And so just to return to my son,

所以我们把话题回到我的儿子

when I was preparing this talk, he was looking over my shoulder,

当我在准备这个演讲时，他在我身后看着

and I showed him the clips I was going to show to you today,

我给他看了这段我今天将要给你们看的录相

and I asked him for permission -- granted.

我征求他的同意，他同意了

And then I went on to reflect,

然后我想

"Isn't it amazing,

“这真是神奇的事情

this entire database, all these recordings,

整个数据库， 所有这些录相

I'm going to hand off to you and to your sister" --

我会给交给你和你的妹妹”

who arrived two years later --

妹妹是两年后出生的

"and you guys are going to be able to go back and re-experience moments

“你们两个将能够回顾重温

that you could never, with your biological memory,

你们生物记忆无法

possibly remember the way you can now?"

记得的这些时刻。”

And he was quiet for a moment.

那一刻他很安静

And I thought, "What am I thinking?

我想：”我在想什么啊？

He's five years old. He's not going to understand this."

他才5岁， 他不会理解这些。 “

And just as I was having that thought, he looked up at me and said,

而正当我怎么想着，他抬头对我说：

"So that when I grow up,

“那等我长大了，

I can show this to my kids?"

我可以给我的孩子们看，是吗？”

And I thought, "Wow, this is powerful stuff."

我想：“哇， 这玩意儿真是太强大了。”

So I want to leave you

所以，我要给各位

with one last memorable moment

留下最后一个值得回忆的

from our family.

家庭记忆

This is the first time our son

这是我儿子第一次

took more than two steps at once --

走了迈出两步的情形

captured on film.

拍摄在录像中

And I really want you to focus on something

我希望你们看的时候

as I take you through.

注意到其中的一点

It's a cluttered environment; it's natural life.

周围有点闹，这是自然的环境

My mother's in the kitchen, cooking,

我妈在厨房做饭

and, of all places, in the hallway,

就在过道里

I realize he's about to do it, about to take more than two steps.

我意识到他就要迈步了，大概一两步的样子

And so you hear me encouraging him,

因此各位可以听到我在鼓励他

realizing what's happening,

我感到有事要发生

and then the magic happens.

然后妙事发生了

Listen very carefully.

请仔细听

About three steps in,

大概在走了三步后

he realizes something magic is happening,

他感到了美妙的事情发生了

and the most amazing feedback loop of all kicks in,

令人惊讶的反应循环作用全部启动

and he takes a breath in,

他松了一口气

and he whispers "wow"

轻轻地说了声：“哇”

and instinctively I echo back the same.

我也凭着直觉说了同样的话

And so let's fly back in time

我们现在回到那一刻

to that memorable moment.

回到那个令人难忘的一刻
