What is turn-taking?

People pause mid-sentence constantly. Thinking, breathing, checking a calendar, looking for a ZIP code.

A system that treats every pause as a finished turn interrupts. One that waits too long leaves an awkward silence and the caller starts again.

This is the tell most callers actually notice. The voice can be excellent and the call still feels wrong because the rhythm is off.

Say a caller is reading her callback number off a business card. People don't say ten digits in one breath. She says "five five five," pauses for about a second while her eyes find the next group, then says "zero one," pauses again, and finishes with "six seven."

Suppose the system decides a turn is over after 700 milliseconds of silence. It hears "five five five," waits, and jumps in to thank her and ask for the best time to reach her. Now the caller is mid-number and being asked something else. She starts over, louder, and her second attempt collides with the assistant's apology. The words were all recognized correctly, and the call still went wrong, because the mistake was about timing: a one-second pause inside a phone number isn't the end of anything.

You can't set the timing yourself on most systems, but you do control the wording, and wording changes how people pause. Open questions produce long, wandering answers with thinking gaps in them. "Tell me about the problem" invites three pauses. "Is the leak inside the house or outside?" invites none.

Ask for one thing per question. Take "Can I get your name, address and a good callback number?" as an example. The caller stops after each item to remember what came next, and every stop looks like a finished turn. Three short questions go faster than one long one.

For numbers and addresses, name the format you're expecting. Asking for "your ten-digit phone number" instead of "your number" tells the caller when they're done, and it tells whatever's listening too. Read a week of transcripts for places where the assistant and caller talk over each other, and you'll usually find the same two questions behind most of them.

GreetKeeper waits for the caller rather than jumping at the first gap, which matters most when someone is reading out an address or a date.

Where the wording invites a long answer, the transcript shows it, and shortening your question usually fixes the rhythm faster than any setting.

Callers can interrupt the assistant and be heard, so an over-long greeting costs a moment rather than a whole turn.
