Oxygen speech and hearing

"this being, in the daytime
used to converse with men."

operatiion includes communication by speech

"its voice was articulate and human"

there exists a 3 part set of ideas about 1) they operate in air, operatiion includes communication by speech, a back and forth dialog w ppl, involving both speech and hearing

so these exotic creatures (exoanimals?) must have some sound-producing organ in their body, and they must also have anatomical structures to hear with, something that functions like ears

When they operate in an atmosphere of air they breathe what? Oxygen?

Probably so. It stands to reason physically and biologically - oxidation produces lots of energy.

There are other ways to respire and other substances that odd or niche that living things use for respiring, pba -- but we'll talk about that.

But oxidation is a great source of energy, stong enough to power the biological engines of animal life everywhere on this world.

It's a good bet for life elsewhere too.

A biological organ with which to produce sounds

ALIEN VOCAL CHORDS?

larynx

trachea

sphrynx

then there are cetaeceans - almost all produce sound to communicate...none have vocal chords

but it's all like a reed instrument

And in every case it's anatomicaly a part of each kind of animal's respiratory system.

Might the alien anatomy be evolved in a similar way?
