I work with children孩子 with autism自闭症.
0
721
2670
我从事关于自闭症儿童的工作。
00:15
Specifically特别, I make technologies技术
1
3391
1914
具体而言,我发明技术
00:17
to help them communicate通信.
2
5305
2171
来帮助他们交流。
00:19
Now, many许多 of the problems问题 that children孩子
3
7476
1539
许多自闭症儿童所面临的问题,
00:21
with autism自闭症 face面对, they have a common共同 source资源,
4
9015
3763
它们有一个共同的根源,
00:24
and that source资源 is that they find it difficult
5
12778
2094
而这个根源就是他们觉得
00:26
to understand理解 abstraction抽象化, symbolism象征.
6
14872
5260
很难理解抽象概念和符号。
00:32
And because of this, they have
a lot of difficulty困难 with language语言.
7
20132
4652
因此,他们在语言上存在很大的困难。
00:36
Let me tell you a little bit about why this is.
8
24784
3015
让我来告诉你们一些会这样的原因
00:39
You see that this is a picture图片 of a bowl of soup.
9
27799
3934
你看这是一碗汤的图片。
00:43
All of us can see it. All of us understand理解 this.
10
31733
2485
我们都可以看见它。我们都能理解这个。
00:46
These are two other pictures图片 of soup,
11
34218
2312
这里是另外两张汤的图片。
00:48
but you can see that these are more abstract抽象
12
36530
2067
但是你可以看到,这些更加抽象。
00:50
These are not quite相当 as concrete具体.
13
38597
1856
这些并不那么具体。
00:52
And when you get to language语言,
14
40453
2174
而当你使用语言的时候,
00:54
you see that it becomes a word
15
42627
1868
你看它变成了一个单词
00:56
whose谁的 look, the way it looks容貌 and the way it sounds声音,
16
44495
3261
它看起来,听起来
00:59
has absolutely绝对 nothing to do
with what it started开始 with,
17
47756
2912
都跟刚开始的或代表的一碗汤,
01:02
or what it represents代表, which哪一个 is the bowl of soup.
18
50668
2830
没有半点关系。
01:05
So it's essentially实质上 a completely全然 abstract抽象,
19
53498
2900
所以它本质上是完全抽象的,
01:08
a completely全然 arbitrary随意 representation表示 of something
20
56398
2576
一个对现实生活中事物
01:10
which哪一个 is in the real真实 world世界,
21
58974
1163
很随意的陈述,
01:12
and this is something that children孩子 with autism自闭症
22
60137
1791
这才是自闭症儿童
01:13
have an incredible难以置信 amount of difficulty困难 with.
23
61928
3164
有极大困难的地方。
01:17
Now that's why most of the people
that work with children孩子 with autism自闭症 --
24
65092
2751
这就是为什么如今大多数从事自闭症儿童工作的人
01:19
speech言语 therapists治疗师, educators教育工作者 --
25
67843
1878
——语言治疗师们,教育者们
01:21
what they do is, they try to help children孩子 with autism自闭症
26
69721
2633
——他们所做的是帮助自闭症儿童交流,
01:24
communicate通信 not with words, but with pictures图片.
27
72354
3229
不是通过文字,而是通过图片。
01:27
So if a child儿童 with autism自闭症 wanted to say,
28
75583
1930
于是如果一个自闭症儿童想说,
01:29
"I want soup," that child儿童 would pick
29
77513
2458
"I want soup"(我要汤),那个孩子将会拿起
01:31
three different不同 pictures图片, "I," "want," and "soup,"
30
79971
2260
三张不同的图片,"I"(我),"want"(要)和"soup"(汤)
01:34
and they would put these together一起,
31
82231
1609
他们会将这些拼凑在一起,
01:35
and then the therapist治疗师 or the parent would
32
83840
1867
然后治疗师或者家长就能理解
01:37
understand理解 that this is what the kid孩子 wants to say.
33
85707
1887
这就是孩子想要说的。
01:39
And this has been incredibly令人难以置信 effective有效;
34
87594
1778
而且这已经卓有成效了;
01:41
for the last 30, 40 years年份
35
89372
2141
在过去的30,40年间
01:43
people have been doing this.
36
91513
1613
人们一直在这样做。
01:45
In fact事实, a few少数 years年份 back,
37
93126
1349
事实上,几年前,
01:46
I developed发达 an app应用 for the iPadiPad的
38
94475
2675
我在iPad上开发了一个app
01:49
which哪一个 does exactly究竟 this. It's called AvazAvaz,
39
97150
2255
就是这样的运作的。它叫做Avaz,
01:51
and the way it works作品 is that kids孩子 select选择
40
99405
2279
它是这样运行的:孩子们选择
01:53
different不同 pictures图片.
41
101684
1321
不同的图片。
01:55
These pictures图片 are sequenced测序
together一起 to form形成 sentences句子,
42
103005
2570
这些图片排列成句子,
01:57
and these sentences句子 are spoken out.
43
105575
1719
然后这些句子被读出来。
01:59
So AvazAvaz is essentially实质上 converting转换 pictures图片,
44
107294
3025
所以 Avaz 基本上在转译图片,
02:02
it's a translator翻译者, it converts转换 pictures图片 into speech言语.
45
110319
3960
他是个翻译器,它将图片翻译成语音。
02:06
Now, this was very effective有效.
46
114279
1718
现在,这已经很有效了。
02:07
There are thousands数千 of children孩子 using运用 this,
47
115997
1384
有数千个孩子正在使用这个,
02:09
you know, all over the world世界,
48
117381
1430
你知道的,遍布全世界,
02:10
and I started开始 thinking思维 about
49
118811
2175
于是我开始思考
02:12
what it does and what it doesn't do.
50
120986
2654
它可以做的和不能做的地方。
02:15
And I realized实现 something interesting有趣:
51
123640
1684
我发现了一些有趣的地方:
02:17
AvazAvaz helps帮助 children孩子 with autism自闭症 learn学习 words.
52
125324
4203
Avaz 可以帮助自闭症儿童学习单词。
02:21
What it doesn't help them do is to learn学习
53
129527
2405
它没做到的是帮助他们学习
02:23
word patterns模式.
54
131932
2748
文字模式。
02:26
Let me explain说明 this in a little more detail详情.
55
134680
2472
让我更具体地解释下这个。
02:29
Take this sentence句子: "I want soup tonight今晚."
56
137152
3057
比如这句话:"I want soup tonight"(我要汤今晚)。
02:32
Now it's not just the words
here that convey传达 the meaning含义.
57
140209
4080
它不仅仅是文字传达了意思。
02:36
It's also the way in which哪一个 these words are arranged安排,
58
144289
3140
这些文字的排列方式也起到了作用,
02:39
the way these words are modified改性 and arranged安排.
59
147429
2515
文字被修饰和排列的方式。
02:41
And that's why a sentence句子 like "I want soup tonight今晚"
60
149959
2306
那就是为什么一句话比如"I want soup tonight"(我要汤今晚)
02:44
is different不同 from a sentence句子 like
61
152265
1984
不同于这句
02:46
"Soup want I tonight今晚," which哪一个
is completely全然 meaningless无意义的.
62
154249
3312
"Soup want I tonight"(汤要我今晚),后者是没意义 的。
02:49
So there is another另一个 hidden abstraction抽象化 here
63
157561
2619
所以这里有另一个隐藏的抽象概念
02:52
which哪一个 children孩子 with autism自闭症 find
a lot of difficulty困难 coping应对 with,
64
160180
3557
自闭症儿童很难应对,
02:55
and that's the fact事实 that you can modify修改 words
65
163737
2840
那就是,你可以修辞文字
02:58
and you can arrange安排 them to have
66
166577
2101
你可以对他们进行排序
03:00
different不同 meanings含义, to convey传达 different不同 ideas思路.
67
168678
2895
来得到不同的含义,来表达不同的思想。
03:03
Now, this is what we call grammar语法.
68
171573
3459
这就是我们所说的语法。
03:07
And grammar语法 is incredibly令人难以置信 powerful强大,
69
175032
2036
而且语法极其有用的,
03:09
because grammar语法 is this one component零件 of language语言
70
177068
3157
因为语法是语言的一个这样的组成部分。
03:12
which哪一个 takes this finite有限 vocabulary词汇 that all of us have
71
180225
3489
它用我们所拥有的有限的词汇
03:15
and allows允许 us to convey传达 an
infinite无穷 amount of information信息,
72
183714
4531
使我们表达无限的信息,
03:20
an infinite无穷 amount of ideas思路.
73
188245
2134
无限的思想。
03:22
It's the way in which哪一个 you can put things together一起
74
190379
2002
这是一种你可以将事物连在一起
03:24
in order订购 to convey传达 anything you want to.
75
192381
2168
来表达任何你所要表达的。
03:26
And so after I developed发达 AvazAvaz,
76
194549
2127
于是在我开发了 Avaz 之后,
03:28
I worried担心 for a very long time
77
196676
1568
我担心过很长一段时间
03:30
about how I could give grammar语法
to children孩子 with autism自闭症.
78
198244
3910
关于我该怎样将语法传递给患了自闭症的孩子们。
03:34
The solution came来了 to me from
a very interesting有趣 perspective透视.
79
202154
2275
解决方案来自于一个很有意思的观点。
03:36
I happened发生 to chance机会 upon a child儿童 with autism自闭症
80
204429
3449
我碰巧遇到一个自闭症孩子
03:39
conversing交谈 with her mom妈妈,
81
207878
2109
正在和他的妈妈交谈,
03:41
and this is what happened发生.
82
209987
2094
然后发生了这样的事。
03:44
Completely全然 out of the blue蓝色, very spontaneously自发,
83
212081
2186
完全出乎意料的,很自然地,
03:46
the child儿童 got up and said, "Eat."
84
214267
2463
那个孩子站起来并说道,"Eat"(吃)
03:48
Now what was interesting有趣 was
85
216730
1770
非常有意思的是
03:50
the way in which哪一个 the mom妈妈 was trying to tease out
86
218500
4244
这位妈妈试图梳理出
03:54
the meaning含义 of what the child儿童 wanted to say
87
222744
2213
孩子所以表达的意思
03:56
by talking to her in questions问题.
88
224957
2260
通过提问来与她交谈。
03:59
So she asked, "Eat what? Do
you want to eat ice cream奶油?
89
227217
2593
于是她问道,“吃什么?你想吃冰淇淋吗?
04:01
You want to eat? Somebody else其他 wants to eat?
90
229810
2112
你想吃?还是别人想吃?
04:03
You want to eat cream奶油 now? You
want to eat ice cream奶油 in the evening晚间?"
91
231922
3313
你现在想吃奶油?还是你晚上想吃冰淇淋?“
04:07
And then it struck来袭 me that
92
235235
1514
这件事让我突然想到
04:08
what the mother母亲 had doneDONE was something incredible难以置信.
93
236749
2028
这位妈妈做的事情是不可思议的。
04:10
She had been able能够 to get that child儿童 to communicate通信
94
238777
1994
她已经能够让孩子和她交流想法
04:12
an idea理念 to her without grammar语法.
95
240771
4138
却不需要语法。
04:16
And it struck来袭 me that maybe this is what
96
244909
2696
我突然想到也许这就是
04:19
I was looking for.
97
247605
1385
我一直在寻找的。
04:20
Instead代替 of arranging整理 words in an order订购, in sequence序列,
98
248990
4142
与其将文字 按顺序,按词组,按句子排列,
04:25
as a sentence句子, you arrange安排 them
99
253132
2172
不如将他们安放在
04:27
in this map地图, where they're all linked关联 together一起
100
255304
3811
这个地图中,它们都是联系在一起
04:31
not by placing配售 them one after the other
101
259115
2143
不是通过将他们一个接着一个地排放
04:33
but in questions问题, in question-answer问答 pairs.
102
261258
3284
而是按问题,按 [问题-答案] 成对排列。
04:36
And so if you do this, then what you're conveying输送
103
264542
2358
如果你这样做,那么你所表达的
04:38
is not a sentence句子 in English英语,
104
266900
1986
就不是英文中的一个句子,
04:40
but what you're conveying输送 is really a meaning含义,
105
268886
2966
你所表达的是真实的"意义",
04:43
the meaning含义 of a sentence句子 in English英语.
106
271852
1511
英文句子的"意义"。
04:45
Now, meaning含义 is really the underbelly软肋,
in some sense, of language语言.
107
273363
2932
"意义"在某种程度上是语言的软肋。
04:48
It's what comes after thought but before language语言.
108
276295
3821
它是一种在想法之后语言之前的东西。
04:52
And the idea理念 was that this particular特定 representation表示
109
280116
2503
所以这个想法是,这种特别的表达方式
04:54
might威力 convey传达 meaning含义 in its raw生的 form形成.
110
282619
3261
可能能够用原始形式传递"意义"。
04:57
So I was very excited兴奋 by this, you know,
111
285880
1771
我对此非常兴奋,你知道的,
04:59
hopping跃迁 around all over the place地点,
112
287651
1493
手舞足蹈地,
05:01
trying to figure数字 out if I can convert兑换
113
289144
1771
试图确定我是否能够将
05:02
all possible可能 sentences句子 that I hear into this.
114
290915
2524
所有我听到的句子转换成这样。
05:05
And I found发现 that this is not enough足够.
115
293439
1773
然后我发现这样是不够的。
05:07
Why is this not enough足够?
116
295212
1385
为什么不够呢?
05:08
This is not enough足够 because if you wanted to convey传达
117
296597
1711
不够是因为如果你想要表达
05:10
something like negation否定,
118
298308
2250
某些东西,比如否认,
05:12
you want to say, "I don't want soup,"
119
300558
1736
你会想说,"I don't want soup"(我不想要汤),
05:14
then you can't do that by asking a question.
120
302294
2220
然而你不能通过提问来做到这个,
05:16
You do that by changing改变 the word "want."
121
304514
2285
你通过改变“want”(要)这个词来做到的。
05:18
Again, if you wanted to say,
122
306799
1637
再者,如果你想要说,
05:20
"I wanted soup yesterday昨天,"
123
308436
1980
"I wanted soup yesterday"(我昨天想要汤)
05:22
you do that by converting转换
the word "want" into "wanted."
124
310416
2737
你是通过将“want”转换成“wanted”做到的
05:25
It's a past过去 tense紧张.
125
313153
1666
它是个过去时态。
05:26
So this is a flourish繁荣 which哪一个 I added添加
126
314819
2103
所以这是一个重要的进度
05:28
to make the system系统 complete完成.
127
316922
1576
使我完善这系统。
05:30
This is a map地图 of words joined加盟 together一起
128
318498
1977
这是单词彼此联系在一起的一张图
05:32
as questions问题 and answers答案,
129
320475
1656
通过问题和答案的方式,
05:34
and with these filters过滤器 applied应用的 on top最佳 of them
130
322131
2264
通过顶上这些过滤器的应用
05:36
in order订购 to modify修改 them to represent代表
131
324395
1817
来修改他们来表达
05:38
certain某些 nuances细微之处.
132
326212
1709
某种细微差别。
05:39
Let me show显示 you this with a different不同 example.
133
327921
1951
让我通过一个不同的例子来展示给大家。
05:41
Let's take this sentence句子:
134
329872
1254
就拿这个句子来说吧:
05:43
"I told the carpenter木匠 I could not pay工资 him."
135
331126
1980
"I told the carpenter I could not pay him."(我跟木匠说过了我不能付他钱)
05:45
It's a fairly相当 complicated复杂 sentence句子.
136
333106
1792
这是一个相当复杂的句子。
05:46
The way that this particular特定 system系统 works作品,
137
334898
1893
这个特别的系统工作的方式就是,
05:48
you can start开始 with any part部分 of this sentence句子.
138
336791
2578
你可以以句子的任意部分开始。
05:51
I'm going to start开始 with the word "tell."
139
339369
1698
我将从"tell"(说)这个词开始。
05:53
So this is the word "tell."
140
341067
1462
这就是“说‘(tell)这个单词。
05:54
Now this happened发生 in the past过去,
141
342529
1600
这发生在过去,
05:56
so I'm going to make that "told."
142
344129
2223
所以我将把它变成"说过"(told)。
05:58
Now, what I'm going to do is,
143
346352
1708
现在,我将这样做,
06:00
I'm going to ask questions问题.
144
348060
1756
我将提问,
06:01
So, who told? I told.
145
349816
2364
那么,谁说(told)了?我说(told)了。
06:04
I told whom? I told the carpenter木匠.
146
352180
1927
我跟谁说(told)了?我跟木匠说(told)了。
06:06
Now we start开始 with a different不同 part部分 of the sentence句子.
147
354107
1751
现在让我们从句子的另一个部分开始。
06:07
We start开始 with the word "pay工资,"
148
355858
1867
我们从“付钱”(pay)这个词开始,
06:09
and we add the ability能力 filter过滤 to it to make it "can pay工资."
149
357725
4577
我们加入了能力过滤器,将它变成了“can pay”(能够付钱)。
06:14
Then we make it "can't pay工资,"
150
362302
2101
然后我们将它变成了“can't pay”(不能付钱)
06:16
and we can make it "couldn't不能 pay工资"
151
364403
1599
而且我们将它变成了“couldn't pay”((过去)不能付钱)
06:18
by making制造 it the past过去 tense紧张.
152
366002
1663
通过将它变成过去时态。
06:19
So who couldn't不能 pay工资? I couldn't不能 pay工资.
153
367665
1923
那么谁"couldn't pay"((过去)不能付钱)?我"couldn't pay"((过去)不能付钱)。
06:21
Couldn't不能 pay工资 whom? I couldn't不能 pay工资 the carpenter木匠.
154
369588
2676
不能付钱给谁?我不能付钱付给木匠。
06:24
And then you join加入 these two together一起
155
372264
1731
然后你讲这两个关联在一起
06:25
by asking this question:
156
373995
1350
通过问这样的一个问题:
06:27
What did I tell the carpenter木匠?
157
375345
1737
我跟木匠说什么了?
06:29
I told the carpenter木匠 I could not pay工资 him.
158
377082
4049
我跟木匠说我不能付钱给他。
06:33
Now think about this. This is
159
381131
1937
现在想想这个问题。这是
06:35
—(Applause掌声)—
160
383068
3542
—(掌声)—
06:38
this is a representation表示 of this sentence句子
161
386610
3672
这是对这个句子的一个描述
06:42
without language语言.
162
390282
2435
不需要语言。
06:44
And there are two or three
interesting有趣 things about this.
163
392717
2192
这里有两三个很有意思的现象。
06:46
First of all, I could have started开始 anywhere随地.
164
394909
3131
首先,我可以从任何地方开始。
06:50
I didn't have to start开始 with the word "tell."
165
398040
2243
我没有必要从"tell"(说)这个单词开始。
06:52
I could have started开始 anywhere随地 in the sentence句子,
166
400283
1416
我本可以从句子的任何一个地方开始,
06:53
and I could have made制作 this entire整个 thing.
167
401699
1507
也能弄出这整个东西。
06:55
The second第二 thing is, if I wasn't an English英语 speaker扬声器,
168
403206
2776
第二点是,如果我不是一个说英语的人,
06:57
if I was speaking请讲 in some other language语言,
169
405982
2175
如果我说某种其他的语言,
07:00
this map地图 would actually其实 hold保持 true真正 in any language语言.
170
408157
3156
这个地图能够在任何语言中适用。
07:03
So long as the questions问题 are standardized标准化,
171
411313
1990
只要问题能够被标准化,
07:05
the map地图 is actually其实 independent独立 of language语言.
172
413303
4287
这个地图事实上是独立于语言的。
07:09
So I call this FreeSpeechFreeSpeech,
173
417590
2115
我管这个叫 Free Speech(自由说话),
07:11
and I was playing播放 with this for many许多, many许多 months个月.
174
419705
2935
我玩这个玩了好多好多个月。
07:14
I was trying out so many许多
different不同 combinations组合 of this.
175
422640
2726
我试过关于这个的好多个不同的组合。
07:17
And then I noticed注意到 something very
interesting有趣 about FreeSpeechFreeSpeech.
176
425366
2289
然后我注意到 Free Speech 有一些非常有趣的现象。
07:19
I was trying to convert兑换 language语言,
177
427655
3243
我尝试过将语言进行转换,
07:22
convert兑换 sentences句子 in English英语
into sentences句子 in FreeSpeechFreeSpeech,
178
430898
2384
将英文句子转换成 Free Speech的句子,
07:25
and vice versa反之亦然, and back and forth向前.
179
433282
1752
然后反向转换,然后反复转换。
07:27
And I realized实现 that this particular特定 configuration组态,
180
435034
2255
我意识到这种特别的结构,
07:29
this particular特定 way of representing代表 language语言,
181
437289
2026
这种特别的语言表示方式,
07:31
it allowed允许 me to actually其实 create创建 very concise简洁 rules规则
182
439315
4395
它竟然能让我创造非常简明的规则,
07:35
that go between之间 FreeSpeechFreeSpeech on one side
183
443710
2734
这种规则能够在 Free Speech 和
07:38
and English英语 on the other.
184
446444
1488
英语之间转换。
07:39
So I could actually其实 write this set of rules规则
185
447932
2180
因此我事实上能够写下这些
07:42
that translates转换 from this particular特定
representation表示 into English英语.
186
450112
3395
将特别表示法转换成英语的规则。
07:45
And so I developed发达 this thing.
187
453507
1831
于是我发明了这个东西。
07:47
I developed发达 this thing called
the FreeSpeechFreeSpeech Engine发动机
188
455338
2232
我发明了这个,叫做 Free Speech 引擎
07:49
which哪一个 takes any FreeSpeechFreeSpeech sentence句子 as the input输入
189
457570
2561
它将任何 Free Speech 句子作为输入
07:52
and gives out perfectly完美 grammatical语法的 English英语 text文本.
190
460131
3930
然后输出语法完美的英语文本。
07:56
And by putting these two pieces together一起,
191
464061
1605
通过将这两部分结合在一起,
07:57
the representation表示 and the engine发动机,
192
465666
1881
表示部分和引擎部分,
07:59
I was able能够 to create创建 an app应用, a
technology技术 for children孩子 with autism自闭症,
193
467547
3796
我得以创造一个 app, 一种专为自闭症儿童而生的技术,
08:03
that not only gives them words
194
471343
2499
它不仅教他们文字
08:05
but also gives them grammar语法.
195
473842
3941
它也教他们语法。
08:09
So I tried试着 this out with kids孩子 with autism自闭症,
196
477783
2360
我给患了自闭症的孩子试过这个,
08:12
and I found发现 that there was an
incredible难以置信 amount of identification鉴定.
197
480143
5013
我获得了莫大的肯定。
08:17
They were able能够 to create创建 sentences句子 in FreeSpeechFreeSpeech
198
485156
2720
他们能够使用 Free Speech 来创造那些
08:19
which哪一个 were much more complicated复杂
but much more effective有效
199
487876
2558
比起类似英文语句
08:22
than equivalent当量 sentences句子 in English英语,
200
490434
2899
更复杂却有效多了的语句,
08:25
and I started开始 thinking思维 about
201
493333
1682
然后我开始思考
08:27
why that might威力 be the case案件.
202
495015
1969
为什么是这样的。
08:28
And I had an idea理念, and I want to
talk to you about this idea理念 next下一个.
203
496984
4287
我有一个想法,我后面想要和大家说说这个想法。
08:33
In about 1997, about 15 years年份 back,
204
501271
3142
大概在1997年,大约15年前,
08:36
there were a group of scientists科学家们 that were trying
205
504413
2011
有一群科学家他们试图
08:38
to understand理解 how the brain processes流程 language语言,
206
506424
2389
弄清楚大脑是如何处理语言的,
08:40
and they found发现 something very interesting有趣.
207
508813
1779
然后他们发现了一些有很意思的现象。
08:42
They found发现 that when you learn学习 a language语言
208
510592
1872
他们发现当你还说小孩时学习一门语言
08:44
as a child儿童, as a two-year-old二十岁,
209
512464
2912
比如2岁大,
08:47
you learn学习 it with a certain某些 part部分 of your brain,
210
515376
2366
你使用大脑的特定的部分来学习它,
08:49
and when you learn学习 a language语言 as an adult成人 --
211
517742
1600
当你作为一名成年人来学习它的时候——
08:51
for example, if I wanted to
learn学习 Japanese日本 right now —
212
519342
3911
比如,我现在想学习日语——
08:55
a completely全然 different不同 part部分 of my brain is used.
213
523253
2707
我的大脑的一个完全不同的部分被使用了。
08:57
Now I don't know why that's the case案件,
214
525960
1831
现在我不知道为什么是这样的,
08:59
but my guess猜测 is that that's because
215
527791
1991
但是我猜测那是因为
09:01
when you learn学习 a language语言 as an adult成人,
216
529782
2437
当你作为成年人学习语言的时候,
09:04
you almost几乎 invariably不变地 learn学习 it
217
532219
1616
你几乎总是在
09:05
through通过 your native本地人 language语言, or
through通过 your first language语言.
218
533835
4266
通过你的母语或者通过你的第一语言在学习它。
09:10
So what's interesting有趣 about FreeSpeechFreeSpeech
219
538101
3252
所以对于 Free Speech 而言有意思的是
09:13
is that when you create创建 a sentence句子
220
541353
1802
当你创造一个句子
09:15
or when you create创建 language语言,
221
543155
1695
或者当你创造语言时,
09:16
a child儿童 with autism自闭症 creates创建
language语言 with FreeSpeechFreeSpeech,
222
544850
3070
患了自闭症的孩子通过 Free Speech 创造语言,
09:19
they're not using运用 this support支持 language语言,
223
547920
1833
他们没有使用这种语言中介,
09:21
they're not using运用 this bridge language语言.
224
549753
2211
他们没有使用桥梁语言。
09:23
They're directly constructing建设 the sentence句子.
225
551964
2657
他们直接在构造句子。
09:26
And so this gave me this idea理念.
226
554621
2193
这给了我这样一个想法。
09:28
Is it possible可能 to use FreeSpeechFreeSpeech
227
556814
2024
这样是可能的吗?不仅仅将 Free Speech
09:30
not for children孩子 with autism自闭症
228
558838
2510
给自闭症儿童使用
09:33
but to teach language语言 to people without disabilities残疾人?
229
561348
6262
也给没有缺陷的人学习语言用?
09:39
And so I tried试着 a number of experiments实验.
230
567610
1978
于是我尝试了一些实验。
09:41
The first thing I did was I built内置 a jigsaw拼图 puzzle难题
231
569588
2948
首先我做的时建造一个拼图游戏
09:44
in which哪一个 these questions问题 and answers答案
232
572536
1970
它的问题和答案
09:46
are coded编码 in the form形成 of shapes形状,
233
574506
1835
以图形和颜色
09:48
in the form形成 of colors颜色,
234
576341
1138
的形式编码,
09:49
and you have people putting these together一起
235
577479
1849
然后你让人们把他们拼凑在一起
09:51
and trying to understand理解 how this works作品.
236
579328
1773
然后试图理解这是怎么运作的。
09:53
And I built内置 an app应用 out of it, a game游戏 out of it,
237
581101
2376
我通过它制作了一个应用,是一个游戏
09:55
in which哪一个 children孩子 can play with words
238
583477
2661
孩子们可以用文字游戏
09:58
and with a reinforcement加强,
239
586138
1704
然后巩固,
09:59
a sound声音 reinforcement加强 of visual视觉 structures结构,
240
587842
2585
用声音强化视觉结构,
10:02
they're able能够 to learn学习 language语言.
241
590427
2013
让他们学习语言。
10:04
And this, this has a lot of potential潜在, a lot of promise诺言,
242
592440
2736
然后这个,这个有很大的潜力,很多承诺,
10:07
and the government政府 of India印度 recently最近
243
595176
1975
而且印度政府最近
10:09
licensed领有牌照 this technology技术 from us,
244
597151
1404
从我们这项技术授权,
10:10
and they're going to try it out
with millions百万 of different不同 children孩子
245
598555
2074
他们将在上百万不同的儿童身上使用
10:12
trying to teach them English英语.
246
600629
2605
尝试教他们英语。
10:15
And the dream梦想, the hope希望, the vision视力, really,
247
603234
2614
而这个梦想,希望,远景,实际上,
10:17
is that when they learn学习 English英语 this way,
248
605848
3082
就是他们能够用这种方式学习英语,
10:20
they learn学习 it with the same相同 proficiency精通
249
608930
2643
他们想能够将它学得熟练得
10:23
as their mother母亲 tongue.
250
611573
3718
跟他们的母语一样。
10:27
All right, let's talk about something else其他.
251
615291
3816
好吧,让我们来谈点别的东西。
10:31
Let's talk about speech言语.
252
619107
1997
让我们谈谈语言。
10:33
This is speech言语.
253
621104
1271
这个是语言,
10:34
So speech言语 is the primary mode模式 of communication通讯
254
622375
1962
语言是我们之间
10:36
delivered交付 between之间 all of us.
255
624337
1613
交流主要模式。
10:37
Now what's interesting有趣 about speech言语 is that
256
625950
1855
关于语言有意思的是
10:39
speech言语 is one-dimensional一维.
257
627805
1245
语言是一维的。
10:41
Why is it one-dimensional一维?
258
629050
1359
为什么是一维的呢?
10:42
It's one-dimensional一维 because it's sound声音.
259
630409
1568
它是一维的因为它是声音。
10:43
It's also one-dimensional一维 because
260
631977
1539
它是一维的也是因为
10:45
our mouths嘴巴 are built内置 that way.
261
633516
1205
我们的嘴是那样构造的。
10:46
Our mouths嘴巴 are built内置 to create创建
one-dimensional一维 sound声音.
262
634721
3512
我们的嘴被构造得生产一维的声音。
10:50
But if you think about the brain,
263
638233
2866
但是如果你想想大脑,
10:53
the thoughts思念 that we have in our heads
264
641099
1764
在我们脑子中的思法
10:54
are not one-dimensional一维.
265
642863
2102
不是一维的。
10:56
I mean, we have these rich丰富,
266
644965
1459
我的意思是,我们拥有这些丰富的,
10:58
complicated复杂, multi-dimensional多维 ideas思路.
267
646424
3028
复杂的,多维的思想。
11:01
Now, it seems似乎 to me that language语言
268
649452
1690
现在,对我而言好像是这样的
11:03
is really the brain's大脑的 invention发明
269
651142
2332
语言确实是大脑的发明
11:05
to convert兑换 this rich丰富, multi-dimensional多维 thought
270
653474
3096
将这种丰富的,多维的想法
11:08
on one hand
271
656570
1587
进行转换,一方面,
11:10
into speech言语 on the other hand.
272
658157
1923
转换成语言,另一方面。
11:12
Now what's interesting有趣 is that
273
660080
1762
现在有趣的是
11:13
we do a lot of work in information信息 nowadays如今,
274
661842
2568
我们如今在做大量的信息化工作,
11:16
and almost几乎 all of that is doneDONE
in the language语言 domain.
275
664410
3079
而且几乎所有的工作都是在语言领域的。
11:19
Take Google谷歌, for example.
276
667489
1939
比如Google,打个比方吧。
11:21
Google谷歌 trawls拖网 all these
countless无数 billions数十亿 of websites网站,
277
669428
2677
Google 网罗了数十亿的网站,
11:24
all of which哪一个 are in English英语,
and when you want to use Google谷歌,
278
672105
2725
都是英文网站,当你想要使用 Google 时,
11:26
you go into Google谷歌 search搜索, and you type类型 in English英语,
279
674830
2450
你进入 Google 搜索,然后你输入英文,
11:29
and it matches火柴 the English英语 with the English英语.
280
677280
4163
然后它将英文与英文匹配。
11:33
What if we could do this in FreeSpeechFreeSpeech instead代替?
281
681443
3583
如果我们能够用 Free Speech 来替代这件事会怎样呢?
11:37
I have a suspicion怀疑 that if we did this,
282
685026
2301
我有一个猜想就是如果我们做到了这个,
11:39
we'd星期三 find that algorithms算法 like searching搜索,
283
687327
2068
我们就会发现类似于搜索,
11:41
like retrieval恢复, all of these things,
284
689395
2325
类似于检索,所有这样的算法,
11:43
are much simpler简单 and also more effective有效,
285
691720
3075
简单得多同时也有效得多了,
11:46
because they don't process处理
the data数据 structure结构体 of speech言语.
286
694795
4417
因为他们不是处理语言的信息结构,
11:51
Instead代替 they're processing处理
the data数据 structure结构体 of thought.
287
699212
5976
而是他们处理想法的信息结构。
11:57
The data数据 structure结构体 of thought.
288
705188
2808
想法的信息结构。
11:59
That's a provocative挑衅 idea理念.
289
707996
2076
这是个令人振奋的主意。
12:02
But let's look at this in a little more detail详情.
290
710072
2142
但是让我们更仔细的想想这个问题。
12:04
So this is the FreeSpeechFreeSpeech ecosystem生态系统.
291
712214
2366
这就是 Free Speech 生态体系。
12:06
We have the Free自由 Speech言语
representation表示 on one side,
292
714580
2884
我们把 Free Speech 的表示法放置在一个站点上,
12:09
and we have the FreeSpeechFreeSpeech
Engine发动机, which哪一个 generates生成 English英语.
293
717464
2228
我们有 Free Speech 引擎, 它生成英文。
12:11
Now if you think about it,
294
719694
1725
现在大家思考一下这个,
12:13
FreeSpeechFreeSpeech, I told you, is completely全然
language-independent语言无关.

Free Speech,我已经跟大家讲过,是完全语言独立的。
12:15
It doesn't have any specific具体 information信息 in it
296
723963
2087
他没有任何特定的信息在里面
12:18
which哪一个 is about English英语.
297
726050
1228
关于英语的。
12:19
So everything that this system系统 knows知道 about English英语
298
727278
2800
于是这个系统所知的所有关于英语的
12:22
is actually其实 encoded编码 into the engine发动机.
299
730078
4620
事实上都被编码写入了引擎。
12:26
That's a pretty漂亮 interesting有趣 concept概念 in itself本身.
300
734698
2237
它本身就是一个非常有趣的概念。
12:28
You've encoded编码 an entire整个 human人的 language语言
301
736935
3604
你已经将整个人类的的语种编码
12:32
into a software软件 program程序.
302
740539
2645
写入了一个软件程序中。
12:35
But if you look at what's inside the engine发动机,
303
743184
2531
但是如果你看看引擎里面有什么,
12:37
it's actually其实 not very complicated复杂.
304
745715
2358
他实际上并不是很复杂。
12:40
It's not very complicated复杂 code.
305
748073
2105
不是非常复杂的代码。
12:42
And what's more interesting有趣 is the fact事实 that
306
750178
2672
更有趣的情况是
12:44
the vast广大 majority多数 of the code in that engine发动机
307
752850
2203
引擎里绝大多数的代码
12:47
is not really English-specific英语专用.
308
755053
2412
都不是英文特有的。
12:49
And that gives this interesting有趣 idea理念.
309
757465
1895
这给出的这样一个有趣的想法。
12:51
It might威力 be very easy简单 for us to actually其实
310
759360
2038
或许对我们来说
12:53
create创建 these engines引擎 in many许多,
many许多 different不同 languages语言,
311
761398
3826
用许多不同的语言来创造这些引擎是很容易的,
12:57
in Hindi印地语, in French法国, in German德语, in Swahili斯瓦希里.
312
765224
6354
比如用印地语,法语,德语,斯瓦希里语。
13:03
And that gives another另一个 interesting有趣 idea理念.
313
771578
2799
这给了我们另一个有趣的想法。
13:06
For example, supposing假如 I was a writer作家,
314
774377
2654
比如,假设我是一名作家,
13:09
say, for a newspaper报纸 or for a magazine杂志.
315
777031

比方说,为报社或者为杂志工作。

13:23
and they could read it in their own拥有 mother母亲 tongue,

13:26
in their native本地人 language语言.
321

3939
用他们的当地语言。
13:30
I mean, this is an incredibly令人难以置信 attractive有吸引力 idea理念,
322

13:33
especially特别 for India印度.
