ABOUT THE SPEAKER
Rébecca Kleinberger - Voice expert
Rébecca Kleinberger is a voice expert pursuing research as a PhD candidate in the MIT Media Lab’s Opera of the Future group.

Why you should listen

Rébecca Kleinberger creatively mixes science, engineering, design and art to explore ways to craft experiences for vocal connection. As part of this work, she designs unique experiences to help people connect with themselves and with others. She accomplishes this using approaches that include projection mapping, virtual reality, rapid prototyping, deep learning, real-time digital signal processing, lasers, wearable technologies and robotics. See examples ranging from a projection ball gown to a memory music box to assistive wearable devices for stutterers on her portfolio.

Throughout six years of work on self-reflection technologies, Kleinberger has developed unique expertise on the human voice as a means of self-connection as well as with others and between species. Her research spans a wide range of fields including neurology, human-computer interaction, psychology, cognitive sciences, physics, biology, clinical research, linguistics, communication theory and assistive technologies. With these tools, people discover more about themselves and the expression they project.

Kleinberger's work was featured on the cover of the Financial Times Magazine and has been shown at a wide range of events and venues including the Museum of Fine Art in Boston, Le Laboratoire in Paris, Siggraph Art exhibition in Los Angeles, the "Hacking Consciousness"exhibit at the Harvard Divinity School and EMF camp in the UK. She has collaborated with Microsoft Research UK and the Google Magenta team and has presented her research at a host of international conferences. Working with Tod Machover, head of the Opera of the Future group, and other group members, her research has also been deployed outside the MIT Media Lab as part of live shows and novel esthetic experiences at Maison Symphonique de Montreal, the Lucerne Festival in Switzerland and the Winspear Opera House in Dallas. Her work has also been featured in Engadget and "60 Minutes."

Kleinberger graduated from École National des Arts et Métiers in Paris with a Master's of Mechanical Engineering and from University College London with a Master of Research in Virtual Environments, Imaging and Visualization. She is also experienced in the art of shearing sheep and raising hedgehogs.

Rébecca Kleinberger: Why you don't like the sound of your own voice

Rébecca Kleinberger: Zašto ne volite zvuk svog glasa?

Filmed:
2,468,958 views

Vaš glas odgovara načinu na koji vas drugi vide, ali vaš odnos prema vašem glasu nije tako jednostavan. Rébecca Kleinberger proučava kako koristimo i razumijemo naše glasove i glasove drugih. Objašnjava zašto možda ne volite čuti svoj glas na snimkama, razlike između vašeg vanjskog, unutrašnjeg i unutarnjeg glasa -- i nevjerojatne informacije koje šaljete, a da toga niste ni svjesni.

od samih riječi i podataka,
02:23
we sharePodjeli basicallyu osnovi who we are.
36
131600

dijelimo ono što jesmo.
02:25
And our voiceglas is indistinguishableNe razlikuje
from how other people see us.
37
133760

A nema razlike između našeg glasa
i načina na koji nas ljudi vide.

It is a maskmaska that we wearnositi in societydruštvo.

02:34
But our relationshipodnos with our ownvlastiti voiceglas
is fardaleko from obviousočigledan.
39
142000
2810
No, naš odnos s našim
glasom nije toliko jednostavan.
02:37
We rarelyrijetko use our voiceglas for ourselvessebe;
we use it as a giftdar to give to othersdrugi.
40
145840
4776
Rijetko koristimo glas za sebe; koristimo
ga kao dar koji dajemo drugima.
02:42
It is how we touchdodir eachsvaki other.

Na taj način dodirujemo jedni druge.
02:45
It's a dialecticaldijalektički groomingkonjušar.
42

To je dijalektičko njegovanje.
02:47
But what do we think about our ownvlastiti voiceglas?
43
155800

Your voiceglas is alsotakođer very linkedpovezan

You have a differentdrugačiji voiceglas

If I take a little snippetIsječak

Da uzmem djelić vašeg

05:27
I can know whetherda li you're talkingkoji govori

94

mogu znati razgovarate li

95

05:32
We can alsotakođer use, as a predictorprediktor,

Kao pokazatelja možemo
koristiti i postavu glasa.
05:38

Znači, kako odlučite postaviti svoj

05:41
And you vocalvokalne posturedržanje,
when you talk to your spousesuprug,
98
329960

05:50
So there is a lot to learnnaučiti
from listeningslušanje to voicesglasovi.
100
338560
2440
Dakle, možemo puno
naučiti slušajući glasove.
05:54
And I believe this has to startpočetak
with understandingrazumijevanje
101
342080
2376
Mislim da to mora početi razumijevanjem
05:56
that we have more than one voiceglas.
102
344480
2016
da imamo više od jednog glasa.
05:58
So, I'm going to talk
about threetri voicesglasovi that mostnajviše of us possesposjeduju,
103
346520
3856
Govorit ću o tri glasa
koje većina nas ima,
06:02
in a modelmodel of what I call the maskmaska.
104
350400
2320
prema uzorku kojeg nazivam maskom.
06:05
So when you look at the maskmaska,
105
353520
1976
Kada pogledate masku,
06:07
what you see is a projectionprojekcija
of a characterlik.
106
355520
2280
vidite projekciju karaktera.
06:10
Let's call that your outwardprema van voiceglas.
107
358360
2136
Nazovimo to vašim vanjskim glasom.
06:12
This is alsotakođer the mostnajviše classicklasik way
to think about the voiceglas,
108
360520
2816
To je, također, i najčešći
način razmišljanja o glasu,
06:15
it's a way of projectingstrše
yourselfsami in the worldsvijet.
109

06:18
The mechanismmehanizam for this projectionprojekcija

And then the way you openotvoren and closeblizu

trakt oblikovati zvuk.
06:34
So everyonesvatko has the sameisti mechanismmehanizam.
116

Dakle, svatko ima isti mehanizam.
06:36
But voicesglasovi are quitedosta uniquejedinstvena.
117
384880
1776
No, glasovi su jedinstveni.
06:38
It's because very subtlefin differencesRazlike

118
386680

Zato jer će i najmanja razlika u

06:44
are going to make very subtlefin

119

proizvesti jako male razlike
u vašem vanjskom glasu.
06:48
And your brainmozak is very good
120
396840
2016
A vaš mozak je jako dobar
06:50
at pickingbranje up those subtlefin differencesRazlike
from other people'snarodno outwardprema van voicesglasovi.

07:17
And one of the difficultiespoteškoće with that
is that your voiceglas is alsotakođer not staticstatički.
128
425960
4120
Jedan od problema kod toga je
i taj što vaš glas nije statičan.
07:23
We alreadyveć said that it changespromjene
with everysvaki personosoba you talk to
129
431000
3136
Već smo rekli da se mijenja
ovisno s kime razgovarate,
07:26
but it alsotakođer changespromjene generallyobično
throughoutkroz your life.
130
434160
2936
ali se općenito mijenja i tijekom života.
07:29
At the beginningpočetak
and at the endkraj of the journeyputovanje,
131
437120
2216
Na početku i na kraju putovanja,
07:31
malemuški and femaležena voicesglasovi are very similarsličan.
132
439360
2696
muški i ženski glasovi su jako slični.
07:34
It's very hardteško to distinguishrazlikovati
133
442080
1536
Vrlo je teško razlikovati
07:35
the voiceglas of a very your girldjevojka
from the voiceglas of a very youngmladi boydječak.
134
443640
3120
glas male djevojčice od
glasa malog dječaka.
07:40
But in betweenizmeđu, your voiceglas
becomespostaje a markeroznaka of your fluidtekućine identityidentitet.
135
448280
5096
No između, vaš glas postaje pokazatelj
vašeg promjenjivog identiteta.
07:45
GenerallyOpćenito, for malemuški voicesglasovi
there's a bigvelika changepromijeniti at pubertypubertet.
136
453400
3936
Općenito, muški glasovi jako
se mijenjaju u pubertetu.
07:49
And then for femaležena voicesglasovi,
137
457360
1336
A kod žena
07:50
there is a changepromijeniti at eachsvaki pregnancyTrudnoća
and a bigvelika changepromijeniti at menopausemenopauza.
138
458720
3240
dolazi do velike promjene tijekom
svake trudnoće i u menopauzi.
07:55
So all of that is the voiceglas
other people hearčuti when you talk.
139
463320
4136
Dakle, to je sve glas koji
drugi čuju kada govorite.
07:59
So why is it that we're so
unfamiliarnepoznato with it?
140
467480
3200
Pa zašto nam je onda toliko nepoznat?
08:03
Why is it that it's not
the voiceglas that we hearčuti?
141
471600
3416
Zašto to nije glas koji mi čujemo?
08:07
So, let's think about it.
142
475040
1216
Razmislimo o tome.
08:08
When you wearnositi a maskmaska,
you actuallyzapravo don't see the maskmaska.
143
476280
3520
Kada nosite masku,
zapravo ne vidite masku.
08:12
And when you try to observepromatrati it,
what you will see is insideiznutra of the maskmaska.
144
480640
3920
A kada je pokušate proučiti,
vidjet ćete samo unutarnju stranu.
08:17
And that's your inwardprema unutra voiceglas.
145
485240
1680
I to je vaš glas iznutra.
08:20
So to understandrazumjeti why it's differentdrugačiji,
146
488560
2016
Da bismo razumjeli zašto je drugačiji,
08:22
let's try to understandrazumjeti the mechanismmehanizam
of perceptionpercepcija of this inwardprema unutra voiceglas.
147
490600
3680
pokušajmo razumjeti mehanizme
percepcije tog unutrašnjeg glasa.
08:27
Because your bodytijelo has manymnogi waysnačine
of filteringfiltriranje it differentlyrazličito
148
495560
2936
Vaše tijelo na mnoge načine
taj glas filtrira drugačije
08:30
from the outwardprema van voiceglas.
149
498520
2016
od vanjskog glasa.
08:32
So to perceivedoživljavaju this voiceglas,
it first has to travelputovati to your earsuši.
150
500560
3496
Kako biste uočili taj glas, on prvo
mora putovati do vaših ušiju.
08:36
And your outwardprema van voiceglas
travelsputovanja throughkroz the airzrak
151
504080
2576
Vaš vanjski glas putuje zrakom,
08:38
while your inwardprema unutra voiceglas
travelsputovanja throughkroz your boneskosti.
152
506680
3496
a vaš unutrašnji glas putuje kroz kosti.
08:42
This is calledzvao bonekost conductionprovođenje.
153
510200
1600
To se zove koštana provodljivost.
08:44
Because of this, your inwardprema unutra voiceglas
is going to soundzvuk in a lowerdonji registerRegistrirajte se
154
512640
5015
Zbog toga će vaš
glas iznutra zvučati dublje
08:49
and alsotakođer more musicallyglazbeno harmonicalHarmonijska
than your outwardprema van voiceglas.
155
517679
4721
i melodioznije nego vaš glas izvana.
08:55
OnceJednom it travelsputovanja there,
it has to accesspristup your innerunutrašnji earuho.
156
523400
3896
Jednom kada doputuje,
mora ući u vaše unutarnje uho.
08:59
And there's this other mechanismmehanizam
takinguzimanje placemjesto here.
157
527320
2416
Ovdje je na djelu drugi mehanizam.
09:01
It's a mechanicalmehanički filterfilter,
158
529760
2096
To je mehanički filter,
09:03
it's a little partitiondijeljenje

159

160

2736
svaki puta kada proizvedete zvuk.
09:10
So it alsotakođer reducessmanjuje what you hearčuti.
161
538200
2200
Dakle, umanjuje ono što čujete.
09:13
And then there is a thirdtreći filterfilter,
it's a biologicalbiološki filterfilter.
162
541240
2960
Postoji i treći filter, biološki filter.
09:16
Your cochleapužnice -- it's a partdio of your
innerunutrašnji earuho that processesprocesi the soundzvuk --
163
544880

Vaša pužnica - dio vašeg unutarnjeg
uha koji procesira zvuk -
09:21
is madenapravljen out of livingživot cellsStanice.
164
549160
2056
sastoji se od živih stanica.
09:23
And those livingživot cellsStanice
are going to triggerokidač differentlyrazličito
165
551240
3096
Te žive stanice aktivirat će se drugačije,
09:26
accordingpo to how oftenčesto
they hearčuti the soundzvuk.
166
554360
2576
s obzirom na to kako često čuju zvuk.
09:28
It's a habituationnavikavanje effectposljedica.
167
556960
1400
To je efekt navikavanja.
09:31
So because of this,
168
559400
1536
Zbog toga,
09:32
as your voiceglas is the soundzvuk
you hearčuti the mostnajviše in your life,
169
560960
3056
kako je vaš glas zvuk kojeg
čujete najčešće tijekom života,
09:36
you actuallyzapravo hearčuti it lessmanje
than other soundszvukovi.
170
564040
2480
zapravo ga čujete manje
nego ostale zvukove.
09:39
FinallyKonačno, we have a fourthČetvrta filterfilter.
171
567280
2016
Konačno imamo i četvrti filter.
09:41
It's a neurologicalneurološki filterfilter.
172
569320
1520
To je neurološki filter.
09:43
NeurologistsNeurolozi foundpronađeno out recentlynedavno
173
571760
2456
Neurolozi su nedavno otkrili
09:46
that when you openotvoren your mouthusta
to createstvoriti a soundzvuk,
174
574240
2776
da kada otvorite usta da proizvedete zvuk,
09:49
your ownvlastiti auditorygledaoci cortexkorteks shutsZatvori down.
175
577040
2800
vaša se slušna moždana kora gasi.
09:54
So you hearčuti your voiceglas
176
582400
2896
Dakle, čujete svoj glas,
09:57
but your brainmozak actuallyzapravo never listenssluša
to the soundzvuk of your voiceglas.
177
585320
4280
ali vaš mozak, zapravo,
nikada ne sluša zvuk vašeg glasa.
10:04
Well, evolutionarilyevolucijski
that mightmoć make senseosjećaj,
178
592040
2536
Evolucijski to možda ima smisla,
10:06
because we know cognitivelykognitivno
what we are going to soundzvuk like
179
594600
2976
jer znamo kako ćemo zvučati
10:09
so maybe we don't need
to spendprovesti energyenergija analyzingAnalizirajući the signalsignal.
180
597600
3160
pa možda ne trebamo trošiti
energiju na analiziranje signala.
10:13
And this is calledzvao a corollaryposljedica dischargeiscjedak
181

10:19
The exacttočno definitiondefinicija
of a corollaryposljedica dischargeiscjedak

posljedičnog pražnjenja je

184

10:27
This copykopirati doesn't createstvoriti any motionpokret itselfsebe

10:30

10:38
And for the voiceglas, this corollaryposljedica
dischargeiscjedak alsotakođer has a differentdrugačiji nameime.
188
626120
3480
Za glas, to posljedično
pražnjenje ima drugačiji naziv.
10:42
It is your innerunutrašnji voiceglas.
189
630480
2096
To je vaš unutarnji glas.
10:44
So let's recapitulaterekapitulirati.
190
632600
1816
Pa ponovimo.
10:46
We have the maskmaska, the outwardprema van voiceglas,
191
634440
2056
Imamo masku, vanjski glas,
10:48
the insideiznutra of the maskmaska, your inwardprema unutra voiceglas,
192
636520
3096
unutarnji dio maske, unutrašnji glas
10:51
and then you have your innerunutrašnji voiceglas.
193
639640
2016
i imamo unutarnji glas.
10:53
And I like to see this one
as the puppeteerlutkar
194

2056
Na taj gledam kao na lutkara
10:55
that holdsdrži the stringsžice
of the wholečitav systemsistem.
195
643760
2440
koji drži konce cijelog sustava.
10:59
Your innerunutrašnji voiceglas is
196
647440
1616
Vaš unutarnji glas je
11:01
the one you hearčuti
when you readčitati a texttekst silentlyTiho,

11:08
SometimesPonekad is hardteško to turnskretanje it off,
199
656760
1616
Nekada ga je teško isključiti,
11:10
it's really hardteško to look at the texttekst
writtennapisan in your nativedomaći languagejezik,
200
658400
4056
teško je pročitati tekst na
vašem materinjem jeziku,
11:14
withoutbez havingima this innerunutrašnji voiceglas readčitati it.
201
662480
2080
a da ga ne čita taj unutarnji glas.
11:17
It's alsotakođer the voiceglas
that refuseodbiti to stop singingpjevanje
202
665800
2336
To je i glas koji odbija prestati pjevati
11:20
the stupidglup songpjesma you have in your headglava.
203
668160
1816
onu glupu pjesmu koja vam je u glavi.
11:22
(LaughterSmijeh)
204
670000
1200
(Smijeh)
11:25
And for some people
it's actuallyzapravo impossiblenemoguće to controlkontrolirati it.
205
673280
3696
Nekim ljudima ga je, zapravo,
nemoguće kontrolirati.
11:29
And that's the casespis
of schizophrenicshizofreničar patientspacijenti,
206
677000
2736
I to je slučaj kod
oboljelih od šizofrenije,
11:31
who have auditorygledaoci hallucinationshalucinacije.
207
679760
2016
koji imaju slušne halucinacije.
11:33
Who can't distinguishrazlikovati at all

11:37

209
685160
1496
od onih koji su im u glavi.
11:38
So in our lablaboratorija, we are alsotakođer
workingrad on smallmali devicesuređaji
210
686680
3376
U našem laboratoriju
razvijamo male uređaje
11:42
to help those people
make those distinctionsrazlike
211
690080
2536
koji će pomoći takvim
osobama da shvate razlike
11:44
and know if a voiceglas
is internalinterni or externalvanjski.
212
692640
2640
i prepoznaju je li glas
unutarnji ili vanjski.
11:48
You can alsotakođer think about the innerunutrašnji voiceglas
as the voiceglas that speaksgovori in your dreamsan.
213
696760
4336
Unutarnji glas je i onaj glas
koji govori u vašim snovima.
11:53
This innerunutrašnji voiceglas can take manymnogi formsobrasci.
214
701120
2096
Taj unutarnji glas ima mnogo oblika.
11:55
And in your dreamssnovi, you actuallyzapravo unleashosloboditi
the potentialpotencijal of this innerunutrašnji voiceglas.
215
703240
4216
U snovima, zapravo, oslobađate
potencijal tog unutarnjeg glasa.
11:59
That's anotherjoš work
we are doing in our lablaboratorija:
216
707480
2056
Na tome isto radimo u laboratoriju:
12:01
tryingtežak to accesspristup
this innerunutrašnji voiceglas in dreamssnovi.
217
709560
3160
pokušavamo pristupiti tom
unutarnjem glasu u snovima.
12:06
So even if you can't always controlkontrolirati it,
218
714280
2296
Čak i ako ga ne možete
uvijek kontrolirati,
12:08
the innerunutrašnji voiceglas --
you can always engageangažirati with it
219
716600
2536
unutarnji glas - možete
ga uvijek iskoristiti
12:11
throughkroz dialoguedijalog, throughkroz innerunutrašnji dialoguesdijalozi.
220
719160
2336
kroz dijalog, kroz unutarnje dijaloge.
12:13
And you can even see this innerunutrašnji voiceglas
221
721520
1816
Možete taj unutarnji glas vidjeti
12:15
as the missingnedostaje linkveza
betweenizmeđu thought and actionsakcije.
222
723360
2640
i kao kariku koja nedostaje
između misli i radnji.
12:20
So I hopenada I've left you
with a better appreciationzahvalnost,
223
728640
3136
Nadam se da ćete sada više cijeniti,
12:23

224
731800
3456
nanovo cijeniti, sve vaše glasove
12:27
and the roleuloga it playsigra
insideiznutra and outsideizvan of you --
225
735280
2536
i ulogu koju imaju u vama i izvan vas -
12:29
as your voiceglas is a very criticalkritično
determinantdeterminanta of what makesmarke you humansljudi
226
737840
4416
jer vaš glas je odlučujući faktor u
tome što vas čini ljudskim bićem
12:34
and of how you interactinterakcija with the worldsvijet.
227
742280
2280
i načinu na koji komunicirate sa svijetom.
12:37
Thank you.

Throughout six years of work on self-reflection technologies, Kleinberger has developed unique expertise on the human voice as a means of self-connection as well as with others and between species. Her research spans a wide range of fields including neurology, human-computer interaction, psychology, cognitive sciences, physics, biology, clinical research, linguistics, communication theory and assistive technologies. With these tools, people discover more about themselves and the expression they project.

Kleinberger's work was featured on the cover of the Financial Times Magazine and has been shown at a wide range of events and venues including the Museum of Fine Art in Boston, Le Laboratoire in Paris, Siggraph Art exhibition in Los Angeles, the "Hacking Consciousness"exhibit at the Harvard Divinity School and EMF camp in the UK. She has collaborated with Microsoft Research UK and the Google Magenta team and has presented her research at a host of international conferences. Working with Tod Machover, head of the Opera of the Future group, and other group members, her research has also been deployed outside the MIT Media Lab as part of live shows and novel esthetic experiences at Maison Symphonique de Montreal, the Lucerne Festival in Switzerland and the Winspear Opera House in Dallas. Her work has also been featured in Engadget and "60 Minutes."

Kleinberger graduated from École National des Arts et Métiers in Paris with a Master's of Mechanical Engineering and from University College London with a Master of Research in Virtual Environments, Imaging and Visualization. She is also experienced in the art of shearing sheep and raising hedgehogs.
