Phone Agents People Do Not Hang Up On.

Current speech synthesis is close enough that most callers do not immediately identify it as synthetic. What actually breaks the illusion is timing, not voice quality — a pause that runs a beat too long, or an agent that talks over an interruption. That is why we engineer the latency budget and barge-in handling first; a natural-sounding voice with sloppy turn-taking still reads as a machine.

In a growing number of US states and other jurisdictions, yes — disclosure requirements for automated callers are tightening, and several states now regulate this directly. We build disclosure into the opening turn by default and configure it per jurisdiction where your call routing spans regions. We will flag the specific rules that apply to your call patterns during scoping, though you should confirm the final position with your own counsel.

The agent detects low recognition confidence and adapts — asking for confirmation, offering to switch to SMS or callback, or transferring to a human. What it must never do is guess and act on a misheard instruction, so confidence thresholds are wired to the action risk: confirming a name is cheap, processing a payment on a misheard digit is not.

Sensitive digit capture is routed through a secure path that keeps the values out of transcripts, logs and model context entirely — the agent orchestrates the flow without ever seeing the number. This keeps recordings clean and materially reduces PCI scope. For healthcare deployments we apply the equivalent handling for protected health information.

Twilio, LiveKit, Vonage, SIP trunking, and the major contact centre platforms including Genesys, Five9 and Amazon Connect. We integrate into what you already run rather than replacing your telephony — the agent becomes another destination in your existing routing, so you keep your numbers, your recording policy and your reporting.

Per-minute cost combines speech recognition, model inference, synthesis and telephony, and it is meaningfully lower than a staffed minute in most markets. The honest caveat is that cost per resolved call matters more than cost per minute — an agent that is cheap per minute but transfers half its calls has not saved you anything. We instrument both.
