This is the recording-consent notice — 17 seconds, the first thing every caller hears, and on a short call most of the audio they hear at all. A voice that works here works everywhere; one that grates here defines the demo. Every take below is rendered through the same path that ships, so what you pick is exactly what deploys.
Thanks for calling Northgate Family Dental. Our office is closed right now, so you're speaking with an automated assistant. This call is recorded so our team can follow up with you in the morning. If you'd rather not be recorded, please hang up and call back during business hours.
Rendered with the old direction: “a recorded announcement on a telephone line… do not sound cheerful.” That instruction is why it lands flat — the clip was doing what it was told.
Same sentence, same pipeline, re-directed: “a real person at the front desk who recorded the after-hours greeting themselves — warm, natural, unhurried, never flat or robotic.” The other three clips get their own directions; the 911 line is written for calm authority rather than warmth, because a caller who mistakes it for a recording may not act on it.
marin, the agent's voice.
When the system interrupts to say something the practice is accountable for, the
caller should be able to hear that something changed.
