Speech and Hearing

Postby Mike » Fri, Nov 30 2007, 03:28 PM

It's interesting the way the brain processes speech.
Part 1.

In this example, a recording of someone speaking a phrase was recorded. Then small chunks were removed and replaced with silence:

Now, we take the same phrase and change the gaps to white noise (static). All of a sudden, it's easily understandable and you'd swear that there aren't any gaps.

Our brain fills in the gaps, but it helps to have some sort of noise so we continue to process the sound as speech.

Part Two.

Listen to this sound first:
#1: http://www.mrc-cbu.cam.ac.uk/~mattd/sin ... sws_d1.wav

It doesn't sound like speech at all, does it? Now, listen to this:
#2: http://www.mrc-cbu.cam.ac.uk/~mattd/sin ... ear_d1.wav

Now, go back to the first sound, and I bet you can understand it now. In fact, even if you try not to, you can't help but hear the words in sound #1.
Pretty cool, huh?

OK I got the 2nd one. Pretty neat.

That 1st one. I still have no clue.

ok, try this version of part 1, it's not as extreme.

With silence:

With white noise:

Hmmm. To me the silent version is easier to understand. Must be the brain damage.



This is cool. Try and listen to this mp3 file. Make sure that your speakers are not turned all the way up or you will just hear distortion

My 11 y/o could hear it but my wife and I heard nothing.

Here is the whole story on this.

Hey, I've got good ears... I could hear it. :-)
Keep calm, and park it in the pocket

I remember reading about that one before.
I can barely hear it, Fern can hear it, my kids can definitely hear it.
