What exactly is Voice AI?

Voice AI is an artificial intelligence system capable of holding telephone conversations in natural language. It's not the "press 1 for billing" automated attendant. It's an agent that understands what you say, processes the intent, queries your real data and responds coherently, just like a well-trained employee would.

The technology combines three layers: ASR to convert speech to text, an LLM to understand intent and generate a response, and TTS to convert the response into natural voice. The result is a fluid conversation that doesn't sound like a robot.

Why the phone is still critical in 2026

Despite all the digitalization, the phone remains the channel with the highest first-call resolution rate. When someone calls, they expect to talk to someone now. The problem is cost: a customer service agent in Spain costs €1,200-€1,800/month and can only handle one call at a time.

How IgeraVoice works in practice

IgeraVoice is Igera Solutions' Voice AI system, designed for specific industries. What sets it apart from a generic bot is that it works with your real documents. When a customer calls and asks something, the system doesn't make up the answer: it finds it in your documents and cites it verbatim.

The 3 questions we always get

Does it sound natural? Yes. Current TTS models generate voice indistinguishable from human in fluency and intonation.

What happens when it doesn't know the answer? IgeraVoice has an escalation protocol: it transfers the call to a human or leaves a message to call back. It never makes up information.

How long does implementation take? Between 48 and 72 hours for a standard industry.
