How do Siri and Alexa sound so human? A computer engineer explains

# How AI Assistants Sound Human Siri and Alexa sound natural because software breaks words into tiny sound pieces called phonemes (like "sh" or "p"), then strings them together in the right order and sends electrical signals to a speaker to create realistic speech. Think of it like a computer mimicking what your lungs, vocal cords, and mouth do when you talk—except it's doing it electronically through tiny vibrations. The result is speech that sounds close enough to human voices that we barely notice we're talking to a machine.
