/*
|
||||
* EXAMPLE: Pure Random Motor Babbling
|
||||
*
|
||||
* This example bypasses all linguistic rules, phoneme definitions, and attractor states.
|
||||
* It sends completely random vectors to the articulatory physics engine.
|
||||
*
|
||||
* That is the sound of raw, uncoordinated motor commands! Without a 'brain'
|
||||
* (linguistic rules) to smooth things out and coordinate the glottis with the tongue,
|
||||
* you essentially get the acoustic equivalent of a seizure or extreme distress.
|
||||
*
|
||||
* It proves that human speech is less about having a mouth and more about the
|
||||
* incredibly precise, learned choreography of closing it.
