I have an idea for an experiment. Basically, the experiment would be to create a novel transmission of visual information via the human vocal chords, but not as a traditional human spoken language per se.
The vocal chords are first trained by an external instrument to produce a specific pattern that is associated with an image such as a simple circle. In addition, a "listening" machine is calibrated to process the sounds emanating from the vocal chords.
At first, this doesn't sound so different than language as we use it now and how we interact with voice-recognition technology such as Siri, but what if the vocal chords were trained to produce patterns an order of magnitude more quickly than what is currently achievable? The current world record for speaking is 637 words per minute or 10 words per second.
Also, the patterns that I am thinking of would completely bypass our language processing centers and be immediately received by our visual cortex (or something like that). After all, a picture is worth a thousand words.
So, are there any vocal chord experiments that attempt to synthesize communication externally or come anywhere close to what I am proposing?
