Frequently asked questions
The questions businesses ask most before deploying a voice AI agent.
What is a voice AI agent?
+
A voice AI agent is software that holds natural spoken conversations over the phone or in apps. It listens, understands intent in real time, replies in a human-sounding voice, and takes actions like booking appointments, qualifying leads, answering FAQs, or routing calls — without a human on the line.
Which AI voice agent is best for small businesses?
+
The best voice agent for a small business is one that ships fast, integrates with your existing phone number and calendar, and bills per minute (not per seat). Xonus Voice Agents come pre-trained for booking, lead qualification, and after-hours coverage — most teams are live within a day and pay only for active call time.
How much does a voice AI agent cost?
+
Pricing is usage-based: typically $0.05–$0.30 per minute depending on voice quality, language, and integrations. A small business handling 500 inbound minutes a month usually spends less than one part-time receptionist while answering 24/7 in any language.
How do you train a voice AI agent for your business?
+
Training takes three inputs: your knowledge base (docs, FAQs, scripts), your workflows (calendars, CRM, ticketing), and your brand voice. Xonus ingests all three, builds a deployment in minutes, and lets you refine responses with live transcripts. No prompt engineering required.
Can a voice AI agent replace a human receptionist?
+
For routine work — answering hours, taking messages, booking visits, qualifying inbound leads, escalating urgent calls — yes. For empathy-heavy or complex negotiation calls, voice agents augment humans by handling the queue and warm-transferring the qualified conversations.
Is voice AI reliable for enterprise customer service?
+
Modern voice agents achieve >95% intent accuracy with sub-500ms latency. The reliability question is no longer the model — it's the integration. Xonus uses redundant carriers, fallback to human transfer, and full call logging so nothing falls through.
What languages do AI voice agents support?
+
Xonus voice agents speak 30+ languages with native accents and switch mid-call if the caller does. Common deployments: English, Spanish, French, German, Portuguese, Mandarin, Arabic.
How long does it take to deploy a voice agent?
+
A pre-trained Xonus Voice Employee deploys in under 10 minutes against an existing number. Fully custom agents with bespoke integrations usually go live in 3–7 days.
