There's a specific type of frustration that's hard to explain unless you've experienced it. You call a business. An automated voice picks up. You ask your question. And then — silence. Not a brief pause. A real silence. Long enough that you start wondering if the call dropped, long enough that you pull the phone away from your ear to check the signal bars.
That silence is what we were trying to eliminate when building the telephony dispatcher for Minions.AI, a voice-based service dispatch platform for trade contractors.
In human conversation, the natural gap between one person finishing a sentence and the other beginning a response is around 200 to 300 milliseconds. Anything beyond 600ms starts to feel awkward. At 2,500ms — which was where the original prototype sat — callers would repeat themselves, raise their voice, or hang up. The call experience was technically functional and practically unusable.
