Voice AI

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

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.

What is an AI voice agent?

A voice AI agent answers spoken calls using a language model and text-to-speech rather than a human operator. In WappBlaster you instruct the agent in plain language, choose its model and voice, set its appearance for the website widget, embed it on your site, and enable it to answer WhatsApp voice calls over SIP. Multi-agent workflows let one agent hand a caller to another specialised agent.

Capabilities

What you get

Everything here is documented and shipping today, not on a roadmap.

Instruct in plain language

Describe the agent’s job, tone and boundaries in writing rather than building a call tree.

Model and voice selection

Choose the underlying model and the voice the caller hears, including language fit.

WhatsApp voice call answering

Enable the agent on WhatsApp voice calls through SIP so calls to your number are answered.

Website voice widget

Embed the agent on your site so a visitor can talk instead of typing.

Appearance settings

Control how the widget looks so it matches the site rather than announcing itself as a bolt-on.

Multi-agent workflows

A receptionist agent that qualifies, then hands to a specialist agent or a human.

How it works

Setting it up

  1. 1

    Write the instructions

    What it handles, what it must never promise, when it hands over.

  2. 2

    Choose model and voice

    Match the voice to your audience and language.

  3. 3

    Add voice credits

    Voice runs on its own credit balance, separate from message charges.

  4. 4

    Embed or enable on SIP

    Put it on the website, on WhatsApp calls, or both.

Where it earns its keep

Common uses

  • After-hours reception

    Calls answered and qualified overnight instead of ringing out.

  • Inbound lead qualification

    Ask the three questions before a salesperson spends time.

  • Appointment booking by phone

    Callers who will never use a web form.

  • Order and delivery enquiries

    The highest-volume, lowest-value call type.

  • Website voice support

    A visitor talks to the site rather than reading an FAQ.

  • Overflow during peaks

    Nobody hears an engaged tone during a campaign.

Frequently asked questions

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.
