talkbox without talking possible?

[EBK]

i gotta fuzzbox that sounds like farts in a blender if ya need the schematic, let me know.... lol

A bit OT, but I'm still waiting to see this broccoli smoothie schematic.

if you like sketchy speech synthesis, check out the pink trombone

its quit a fun app to play with for like 5 minutes, then it just gets annoying

cheers, Iain

Now I probably can't go to sleep without hearing woaaaaAaaOooooaAhHhooooAoooooaAo everywhere...

yup me too...

> ....four or five resonant peaks. ...you can often get something "speech-like" with less.

So few household sounds have even two peaks, 2 peaks gives a strong suggestion of "almost speech". (Also as hearing is lost though loud exposure and old age, those peaks are lost, "speech banana".)

> You're feeding the sound in at the other end of the system though, for sure.

There is a theorem in room acoustics that the transmission path measures the same from stage to listener or listener to stage. I know this is first-order useful thinking. I have not crawled into a throat to confirm.

I don't know anything about room acoustics, but I know that a shape one way around is different from a shape the other way around. Whether that is significant or not in this case, I don't know. You're suggesting that not - so the shape and distance from source doesn't make any odds? Otherwise "wide then narrow" would be different from "narrow then wide", right? The "transmission path" you talk about from the lips to the wide cavity of the mouth is much less far than the distance from the vocal cords to the same cavity. So despite the fact the distances from one end to the other are the same measured from either end, the distances from one end to the relevant important structures and features aren't the same at all. Does that matter, or not?

No. Same path, direction does not matter.

I'm sure there is fine-print I have forgotten.

[Fancy Lime]

As long as there is only one path, it should be the same. However, where there are many paths, I would expect there to be differences in how these interfere. My gut tells me that amplitude does not care about the path direction in the end but amplitude as well as phase at the points where paths interfere will be different for different points of origin. I have zero evidence to back that up, though. But I am pretty sure we need to consider interaction between paths to understand what's going on in a resonance chamber.

this thing should sound like a fart in a blender for ya lol

unless i'm forgetting, which is possible/plausible/likely

use at your own risk. i DID end up selling a bunch of these way back when, for some reason. can get enough fuzz where your guitar sounds almost like pitched static.

this tells you that funnels/horns are good for boosting your voice, but also good for louder listening, not that the voice is equally amplified if you turn the horn around. i hope that clears it up a little.

what teh tube in mouth thing of the talk box basically does is like making a hole in the side of the horn and screaming in to that hole, this takes out a big part of the effectiveness of the horn, as it is directly linked to length, volume and curvature.
