Voice Is Quietly Becoming the Default Interface
Sub-300ms realtime speech models turned a novelty into infrastructure. What changes when talking is faster than typing.
Latency was the whole problem
Voice interfaces failed for a decade not because recognition was bad but because the pause was unbearable. Once round-trip latency dropped below the natural gap in human conversation, the interaction stopped feeling like a command line you shout at.
Design for interruption
The single biggest quality jump in voice products comes from handling barge-in gracefully. Users interrupt constantly. An agent that keeps talking over them feels broken no matter how good the model is.
Where it wins first
Hands-busy contexts: driving, clinical notes, field work, kitchens, warehouses. Not because voice is superior everywhere, but because in those contexts a keyboard was never an option.
