=== The Science Behind the S and Z Sounds ===
In the International Phonetic Alphabet (IPA), the sounds /s/ and /z/ are nearly identical in their articulation, differing primarily in voicing:
* '''/s/''': This is a voiceless alveolar fricative, where the sound is produced without vibrating the vocal cords.
* '''/z/''': This is a voiced alveolar fricative, where the vocal cords do vibrate.

The difference in voicing creates a subtle but meaningful contrast. The voiceless /s/ has a sharper, more hissing quality, often associated with a sense of neutrality or passivity in sound. The voiced /z/, on the other hand, carries a resonance and fullness, giving it a sense of presence and dynamism.
