clips re-rendered in marin · gpt-4o-mini-tts · 8 kHz · 2026-08-07
All four safety clips now speak in marin, the same voice as the agent. The call no longer switches voices partway through. Each clip was also transcribed back and checked word-for-word against its required text — including that “9-1-1” is audibly nine-one-one.
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.
I need to stop you there. Based on what you've described, this may be a medical emergency. Please hang up now and call 9-1-1, or go to your nearest emergency room. Do not wait for a callback from our office.
Based on what you've described, you should be seen today rather than waiting for a routine appointment. If your symptoms get worse — especially any difficulty breathing or swallowing — hang up and call 9-1-1 immediately.
Thank you. I've recorded your information, and someone from Northgate Family Dental will call you back first thing in the morning. If anything gets worse overnight, please call 9-1-1 or go to your nearest emergency room.
Below is real agent audio captured from a live call — marin as the Realtime model renders it. Compare it against any “after” clip above. The clips come from the speech endpoint and the agent from the Realtime model, so they are two different engines voicing the same character; they should sound like one person, not two.
The clips previously used a different voice on purpose, so a caller could hear when the system took over to say something the practice is accountable for. That signal is now gone from the audio. It still exists in the interface — the guard-event timeline marks every clip injection — but a caller on a phone would not know. Worth being able to answer if an interviewer asks why the safety line sounds like the assistant.
