Glossary

Voice-agent terms, defined

The vocabulary behind an AI phone agent that acts over the phone — what each term means, and where to go deeper.

AI phone agent
An AI system that handles a business’s phone calls — answering inbound calls and placing outbound calls on the owner’s behalf, on the owner’s okay. Read more →
Outbound voice agent
An AI phone agent that initiates calls to third parties to complete owner-assigned tasks. Placing the call is the irreversible act, gated behind the owner’s okay. Read more →
The commit problem
Deciding when an AI agent may take an irreversible or intent-disclosing action before it is fully certain — the core of an agent that acts, not the voice. Read more →
Answering service
A service that answers inbound business calls and takes messages. An AI phone agent also places outbound calls on the owner’s okay — the part a traditional answering service can’t do.
Intent disclosure
When issuing a tool call leaks what an agent is about to do to a third party — a second axis of irreversibility alongside state-reversibility. A read can be costless to undo yet impossible to un-disclose.
IVR navigation
An agent operating a phone tree (interactive voice response) on someone’s behalf — a setting that is partially observable, latency-bound, and irreversible.
Faithful report-back
After acting, telling the owner precisely what happened — including what irreversibly happened — in accurate terms, not an optimistic summary.
Full-duplex voice agent
A voice system that listens and speaks at the same time, modeling overlap so interruption (barge-in) and backchanneling are native behaviors rather than bolted-on.
