How Speech Jamming Works

Most people don't know this, but Jason was the two time back-to-back copycat world champion. He used to be able to mimic languages that hadn't been invented yet! But that all changed with the digital revolution. Suddenly people weren't so impressed with a kid from the burbs with a mouth like a mirror now that a computer could do it too, and with higher fidelity. It's been a hard road but he's finally at a place where he can talk about that experience, and maybe... even have a machine repeat him while he does it.

GUYS, if you cant hear anything 16khz and above on the youtube video don't worry, youtube's compression cuts off at 15 khz so there was no sound playing for any of the viewers

[remsku]

Youtube crops the sound at 15KHz if I remember right, so don't worry if you didn't hear it even tho you should have

[Azathoth]

Jokes on you, I can hear my tinnitus just fine.

[willb.]

As a lifelong stutterer who has only barely overcome its effects on my speech, I felt the frustration and exhaustion when Jason attempted talking off book. That was real.

[Dpope]

I run a recording studio, and any delay in real time feedback absolutely destroys every single artist

[Swordandsteel]

I’ve had a stutter my entire life, watching you guys struggle with it was hilarious. That looks remarkably like my reaction to a bad bout of stuttering. And yes, the struggle is real. It’s not as bad, as you kinda get used to it over time. But more stressful or nervous situations, it gets tough. Job interviews? First dates, woo boy It’s tough.

Chronic stutterer here with over 10 years of speech therapy!

You guys nailed it, I have wowed my friends with the speech jammer app because with few exceptions it had no effect on me. In fact sometimes it made me speak better. When I was young they were actually testing a device that would sit in your ear and play back your speech milliseconds after it was spoken and had some good results. Not sure where the tech went after that

I didn't realize it until recently, but that mosquito sound thing is really useful. I work in a retirement home, and they have emergency call buttons all over the building. If a button is pushed then all of them display the location and put out a high pitched screeching to make sure everyone checks them. But because it's such a high pitch none of the residents can hear it, so they aren't bothered by someone pulling the emergency cord in their room.

my friend on discord doesn't use a headset, so I can hear myself talking but at a really slow like 1 second delay and he always makes fun of me for stuttering and it fricking annoys me because he's basically speech jamming me and then insults me

[MXGVJake]

To anyone saying they have trouble hearing higher frequencies: YouTube has a feature where it lowers the volume of very high frequency audio to save your ears.

[OlOleander]

By the way, one of the biggest things I learned working an audiology rotation has to do with Jason's opening lines.
If you have trouble *hearing* speech, you may be surprised to learn you may have some hearing loss. If you have trouble *understanding* speech, you may have 2-4k Hz hearing loss or an auditory processing disorder (like me!) Which are far more common than most people think.

[Blalack]

I used to have the mosquito sound as my ringtone back when I was maybe 19 or 20 (on my old SLVR phone). What was cool about it was, you could hear it over the loudest noises. Like we could have music blasting and I could still hear my ringtone. I'm 33 now and it seems like I heard that ringtone recently and I could still hear it. It kind of reminds me of the sound old CRT TVs made. I could tell whenever anyone in the house had turned one on even without the volume. It was less of a sound and more of a sensation. I wonder, has anyone else ever noticed that weird sound/sensation with old, pre-flatscreen TVs?

[briansteel]

Inform your audio tech that the compression for upload messes with dynamic range, which is causing background noises to overpower the higher tones generated.

I'm a sound tech, and considered in the top 5% for hearing. At 25 my hearing range was confirmed 12-25k, were as average hearing is 20-20k. To put it another way, I could hear dog whistles.

I just retested myself a few weeks back, using a oscilloscope and headphones that are rated 10-21k. I registered 15-21k, with a slight dip around 18k. Yet when you claimed to play 14k, the background noises are louder then the tone. Giving an illusion to anyone that watches this, that they can't hear anything 14k or higher.

And here's something you might find interesting. Some people have hearing so sensitive, they can actually hear the barometric pressure change as a storm front moves in. To them, it sounds like a freight train driving through a tunnel in their head.

This has always been one of my absolute favorite episodes of modern rogue, and quite possibly my favorite of all of the db shows

[NorseHorseOfCourse]

Lol any gamer who has experienced the cancer of mic feedback from someone without headphones is probably immune to this at this point

[endthyselfrightlyplx]

I stopped hearing the beeps at the 45 year mark.
I am 18.

[TheyWithABrain]

Let’s take a moment to thank whoever did the captions, they legitimately did the greatest job I’ve ever seen with translating gibberish/stuttering into words

[briancherry]

11:14 - oh my gosh.... speech jamming turned you into William Shatner!

Still waiting for the scooby do series
