Our ears like alliteration. CVCV alternating sounds are easy to pronounce
Vowels are voiced phonemes made with an open, unobstructed vocal tract. They are typically organized depending on the location of the resonant chamber created by your mouth shape.
Vowels like ee, ih, and ee are considered high front, while uh, oh, and ah are low back
Study after study found that humans associate the low back vowels with things that are large, heavy, round, and masculine
And the high front vowels with things that are small, light, thin, sharp, and feminine
Consonants are formed when the vocal tract becomes obstructed, that is when any of the articulators of your mouth and throat touch each other
If the airflow is completely stopped and then bursts out again, the consonant is a plosive. Think p, t, and k. These are the voiceless plosives. Your voice box doesn't vibrate when you make them
If you add voice, you get b, duh, and guh. Voiceless plosives are generally considered to be smaller, lighter, and sharper
Voiced plosives are often seen as more potent or luxurious
If the airflow is not stopped but only restricted, causing friction, the consonant is considered a fricative, like f, s, and sh. Again, these are voiceless
Their voiced counterparts are v, z, and zh
Fricatives are considered soft, quick, and airy
We should also give a special shoutout to the mm sound, classified as a nasal because air passes through your nose when you make it. It's often associated with tasty foods, which is not surprising considering it's the sound we make when we eat something yummy
At the other end of the tastiness spectrum is the diphthong EW, made by combining the E and the OO vowels. This sound doesn't get used much in marketing, perhaps because it's associated with things that are nasty or gross or EW. Think putrid or puke or mucus
