/XPO

Voice agent middleware

Turn a spoken name
into the right extension.

When the XPO voice agent needs to hand a call to a person, this service fuzzy-matches the name it heard against the ASSIST directory — tolerant to transcription errors and Spanish spelling variants — and returns the best-ranked agent with their extension.

No confident match — route to the Customer Care queue.

Live query against the real ASSIST directory (served from Twin). The browser calls a keyless demo proxy — the X-API-Key stays server-side.
