The first sentence is too long to sound like anything particular in Primal. Just as if you heard a paragraph of French, you'd identify it as foreign quickly enough to avoid parsing it. Only shorter sentences are likely to sound like something else amusing to a Primal speaker's ear.
"C'mon boy, c'mere." sounds like three nouns in a row:
Mister Mop. Dictionary. Mister President.
(where "Mister" just means a proper noun, not gender-specific)
"Shhh- be quiet." sounds like:
Only loneliness. Mister Fan.
"Hey! Shut the f*** up! It's five in the morning." sounds like:
Hallway sucks on, and will swallow. A hatch door. Slipperiness. Radio waves. An exponent saves.
"Wait, that... was oddly human sounding." sounds like:
Ceratosaur. Breakfast is to the left of speckled-ness, and does if and only if magnet. The color white blends.
Michelle sounds exactly like the phrase "...and rose". A Primal speaker would probably call her "shel", or "Rose".
Jason sounds somewhat like "chey-sen", which means "Hole times.", as in, a hole keeps track of time. A Primal speaker would probably call him "chey", or "Hole".
Kimberly sounds like two sentences: "Heron. Purring (expressing contentment) does." A Primal speaker might be inclined to call her "kim", or "Heron". Alternately, "pur" might fit...this is actually a common Primal name.
Richard sounds like the phrase "...near-to elder". A Primal speaker would probably call him "churp", or "Elder".
Sarah sounds like the incomplete phrase, "Result-of. The..." A Primal speaker would call her "sair", or "Result".
Matthew sounds vaguely like "Knot. You." A Primal speaker would call him "muoth" (like "moth", but the vowel rhymes with "foot"), for "Knot", and this would be considered an amusing name.
Commander Wiggles sounds vaguely like "Mister light-bulb. Location with phoneme." It sounds ridiculous to a Primal speaker. One would likely call him "meln", or "Light-bulb".
Mister Mailman doesn't really sound Primal-eqsue enough. It's unlikely a Primal speaker would mishear this as anything particular.
Doggy would sound like vaguely like "tiny beak" to a Primal speaker. They might expect the animal to be a small bird rather than a dog.
Hope this helps!
