What is an AI voice agent?
An AI voice agent is a phone assistant powered by speech recognition, a large language model and natural text-to-speech. It holds a real conversation, understands what the caller wants, and takes action: booking, answering, qualifying or transferring. An AI receptionist is the most common type: it answers your business line when your team cannot.

How much does an AI voice agent cost?
A custom AI voice agent starts from $4,500 to build and takes 2 to 3 weeks. Ongoing call costs depend on your call volume and minutes, and we estimate them for you before you commit. For most small businesses the total monthly cost is well below a part-time receptionist's wage.

AI Voice Agent Development questions, answered
Does an AI voice agent sound robotic?
No. Modern voice models sound natural, handle interruptions and pause like a person. You hear and approve the voice before launch.
Can I keep my existing phone number?
Yes. We route your current number to the agent, either for every call or only when your team does not pick up.
What happens when the AI cannot answer?
It transfers the call to a person or takes a message and sends it to your team immediately, with a transcript of the conversation.
Is an AI receptionist legal to use in the UK?
Yes. You should tell callers they are speaking to an automated assistant and handle call recordings in line with UK GDPR. We set up the disclosure and data handling for you.
How quickly can an AI voice agent go live?
Usually within 2 to 3 weeks, including testing with real calls.
