为什么大多数人不喜欢自己声音的录音?
Most people report not liking the sound of their voice recording.
很多人反应说不喜欢他们声音的录音。
So what does that mean?
那这意味着什么呢？
I belive that we have to start with understanding that we have more than one voice.
You have a different voice for every person you talk to
If I take a little snippet of your voice and I analyze it,
如果我截取一小段你的声音然后进行剖析，
I can know whether you’re talking to your mother, to your brother,
我可以知道你是在和你妈妈，哥哥，
your friend or your boss.
朋友，还是你的老板说话。
So all of that is the voice other people hear when you talk.
这都是你说话时别人所听到的声音。
So why is it that we’re so unfamiliar with it?
那为什么我们自己对于这些声音却那么陌生呢？
Why is it that it’s not the voice that we hear?
为什么这些不是我们自己所听到的声音？
So to perceive this voice, it first has to travel to your ears.
为了察觉到这个声音，它最开始传播到你的耳朵。
And your outward voice travels through the air
你的外在声音在空气中传播，
while your inward voice travels through your bones.
同时你内在声音在你的骨头中传播。
This is called bone conduction.
这就是骨传导。
Because of this, your inward voice is going to sound in a lower register
如此一来，你的内在声音的音域会更低，
and also more musically harmonical than your outward voice.
也会比外在的声音听起来更和谐。
Once it travels there, it has to access your inner ear.
当它传播到那里，必须进入到你的内耳。
And there’s this other mechanism taking place here.
这就涉及到另一个原理。
It’s a mechanical filter,
这是一种机械过滤，
it’s a little partition that comes and protects your inner ear
是在你每一次发声的时候
each time you produce a sound.
能够保护你内耳的一种分隔器。
So it also reduces what you hear.
所以你听到的内容也会有所减少。
And then there is a third filter, it’s a biological filter.
还有第三种过滤，是一种生物过滤。
Your cochlea -- it’s a part of your inner ear that processes the sound --
你的耳蜗——用来处理声音的 内耳的一部分——
is made out of living cells.
是由活细胞组成的。
And those living cells are going to trigger differently
那些活细胞会根据它们是否频繁地听到某种声音
according to how often they hear the sound.
而被不同程度地激发。
It’s a habituation effect.
这是一种习惯效应。
So because of this,
因此，
as your voice is the sound you hear the most in your life,
你自己的声音虽然是你一生中最常听到的声音，
you actually hear it less than other sounds.
实际上却比其他声音更少的被你的听觉接收。
You voice is a very complex phenomenon.It requires s synchronization of more than 100 muscles in your body. And by listening to the voice, we can understand possible failures of what happens inside. For example, listening to very specific type of turbulences and nonlinearity of the voice can help predict very early stages of Parkinson’s, just through a phone call. Listening to the breathiness of the voice can help detect heart disease. And we also know that the changes of tempo inside individual words is very good marker of depression. So I hope I’ve left you with a beeter appreciation, a new appreciation of all of your voice and the role it plays inside and outside of you, as your voice is very critical determinant of what makes you humans and of how you interact with the world.
