Can someone debunk this

[pocaracas]

Alternatively, it is well known that as we inhale, often air ends up in the stomach... we could have air go in there all the time and have a special system designed to send out air through the mouth, thus producing speech very similar to ours... but perhaps a bit smellier

Oh.... and this secondary air usage would result in no shortage of actual breath during songs or speech.
There would end up being a lack of air for speech, but never for breathing as that would be a separate system.
