AI voice agent
What is AI voice agent?
An AI voice agent is software that answers a phone call, understands free speech in real time, reasons over the caller's context, and talks back — instead of routing callers through a fixed 'press 1' menu. It chains speech-to-text, a language model, and text-to-speech into one streaming loop, and can call external tools mid-call to look up an order, book an appointment, or hand off to a human with the transcript attached.
More detail
In a modern contact center, an AI voice agent's role is to be the first point of contact on routine calls: it answers instantly, resolves the questions it can from the contact center's knowledge base, and hands the calls that need a human to a human agent with the full transcript attached. Human agents then spend their time on the calls that need judgment — an AI voice agent replaces the IVR menu, not the contact center team.
The quality of an AI voice agent is set by turn latency — the time between a caller finishing speaking and the agent's reply starting. A delay much longer than a human's natural response pause makes the interaction feel broken even when the answer is correct, which is why production AI voice agents run a streaming pipeline (transcribing and generating as audio arrives) rather than a stop-and-wait loop.
The future of voice AI agents points at connected, cross-channel agents: a voice agent that recalls a caller's prior calls, continues the same conversation over SMS, WhatsApp, RCS, or email, and calls tools against live business systems mid-call — one agent configuration running across every channel instead of a separate bot per channel.
On Orbit, an AI voice agent is one agent configuration deployed on inbound and outbound calls over Devotel's own carrier-of-record softswitch, grounded in an uploaded knowledge base, able to call registered tools, and escalating to a human in the same shared inbox that already handles SMS, WhatsApp, RCS, and email — with a published per-turn latency target.
Frequently asked
- What is an AI voice agent?
- An AI voice agent is software that answers a phone call, understands free speech in real time, reasons over the caller's context, and talks back — instead of navigating callers through a fixed 'press 1' phone menu. Modern contact centers use one for routine inbound and outbound calls and escalate the calls that need a human, with the transcript attached.
- What role do AI voice agents play in modern contact centers?
- An AI voice agent is the first point of contact on routine calls: it answers instantly, resolves what it can from the knowledge base, and hands the calls that need judgment to a human agent with the full transcript attached — replacing the IVR menu layer, not the contact center team.
- How is an AI voice agent different from an IVR?
- An IVR walks a caller through a fixed menu of keypad or spoken options against a static decision tree. An AI voice agent interprets free-form speech, holds a multi-turn conversation, and calls external systems mid-call — so it resolves the call itself rather than navigating the caller toward a human or a recording.
- What is the future of voice AI agents?
- Connected, cross-channel agents: a voice agent that remembers a caller's prior calls, continues the same conversation over messaging channels, and acts on live business systems through tool calls — one agent configuration covering every channel rather than a separate bot per channel.
