One: Cut a hole in the box,
Two: a Sphere from the box,
Three: Make them speak with the box,
And that's the way you do it,
It's my voice in a box.
Designed for sufferers of One-Voice, an artifical syrinx allows to speak their dual-tone languages even if one of their two syrinxes has been damaged.
Please see the One-Voice article for more background information.
Some great inventions are due to accidents. This was not one of them, but instead a dedicated effort combining monoduga engineering andknowledge.
Loose lips sink profits
Aside from the mundane processes needed to produce the physical box and strap, the manufacturing requirements are unknown.
The monoduga who invented them is Severed, so even the monoduga hive mind is unaware of the process. Only the inventor themself and those few kliasta who staff the COOP HQ understand how to produce, maintain, and repair them, maintaining a monopoly.
The small metal box simply needs to be attached to the kliasta's neck, usually using an adjustable leather strap. Once in place, it activates automatically when the kliasta speaks.
I can't believe it's not...
It appears to somehow hijack the brain signals being sent to the missing syrinx and produce tones to match the formant and other qualities that the syrinx would have generated naturally. Not only does this ensure the right pitch for the precise intervals needed in kliastan languages, but it even imitates the kliasta's voice as if they still had both their original syrinxes.
Connection, not Sound
One might assume that the magical component of the device draws its energy from the, but it actually appears to be somehow connected to the . This further implies that the box generates sounds from the user's mind, rather than their throat.
Spooky soul box
Regardless of the source, no-one knows how the boxes stay powered. The Spectres' teleporters, a similarly Sphere-powered technology, access the via a shard of an ultra-rare . The artificial syrinxes don't seem to contain such an artifact, which begs the question: How does an inanimate box with no power source draw extraplanar energy that can only be accessed via conscious thought or Philosopher's Stones?
