Voice AI

AI voice agent that picks up the phone, not just the chat

An AI voice agent is software that holds spoken conversations with callers, understanding what they say and answering aloud in real time. Plenty of customers still call. A voice agent answers on the first ring, at 2am, in the language they used, and passes the qualified ones to a human.

AI voice agent in brief

An AI voice agent from WappBlaster answers WhatsApp voice calls over SIP as well as calls placed through a widget embedded on your website, making the WhatsApp engagement platform reachable for customers who prefer to talk. You brief it in plain language instead of drawing a call tree, then choose the language model and the voice it speaks with, and style the widget's appearance to suit the site. The concrete differentiator is multi-agent hand-off: a general agent can pass the caller to a specialised agent, or to a human, when the conversation needs it. That lets one line cover qualification, routine questions and out-of-hours cover, including a call at 2am, in whatever language the caller used. Voice usage runs on its own credits, billed apart from WhatsApp messaging charges. Set hand-over rules before launch so sensitive decisions or upset callers reach a person quickly, and rely on the text AI agent instead if you only expect chat.

AI voice agent FAQ

Straight answers about AI voice agent.

Can it answer WhatsApp voice calls?

Yes. The agent can be enabled for WhatsApp voice calls over SIP, so calls placed to your WhatsApp number are answered by the AI.

Link to this answer

How is voice charged?

Voice runs on a separate credit balance that you top up, because the underlying speech and model costs are usage-based. It is not covered by the flat messaging platform fee.

Link to this answer

Which languages does it handle?

It depends on the model and voice you pick. Both are selectable, so you choose a combination that fits your callers rather than accepting a default.

Link to this answer

Can it transfer to a human?

Yes, through multi-agent workflows: one agent handles the opening and qualification and hands off to another agent or to your team.

How much does an AI voice agent cost with WappBlaster?

Voice is billed from its own credit balance that you top up, kept apart from the flat messaging licence. Usage drives the cost, because speech and model processing are charged by use.

What is the best AI voice agent use for a small business?

After-hours reception is a strong start: calls that would ring out overnight get answered and qualified. Order and delivery enquiries are another good fit because they are frequent and repetitive.

Can I add an AI voice agent to my website?

Yes. Embed the voice widget so visitors can talk instead of type, and adjust its appearance so it matches your site.

Link to this answer

How do I tell an AI voice agent what to do?

Write instructions in plain language: what it handles, what it must never promise and when it should hand over. No call tree has to be built.

Can an AI voice agent book appointments by phone?

Yes. Phone booking is a listed use, serving callers who would never fill in a web form.
