Some of the virtues (or vices) of breathing adaptations for speech
"...it is quite clear that breathing undergoes peculiar changes during speech. What is astonishing about this is that man can tolerate these modifications for an apparently unlimited period of time without experiencing respiratory distress, as is well demonstrated by the interminable speeches with which many a statesman embellishes his political existence."
"...the latter two occupations [playing a wind instrument and singing] require careful instruction and training in proper breathing, whereas speaking for hours continually seems to come all too naturally to many a three-year-old."
From Eric H. Lenneberg's 1967 book Biological Foundations of Language.
