When you can't pick up,
Adam will.
HlasAI is a Slovak AI voice for your business phone. The wave above you moves with Adam's real voice — give it a listen.
This voice is generated by artificial intelligence (ElevenLabs, voice Adam).
0:00Sample call · ringing
The phone is ringing. Your hands are full.
You're under a car, with a customer or up on a roof. You can't answer — and a missed call can be a missed job.
0:01Sample call · Adam answers
Adam answers and says who he is.
He introduces himself as a voice assistant and doesn't pretend to be human — as Article 50 of the EU Artificial Intelligence Act requires. Then he asks what the call is about and holds a conversation, not a press-1 menu.
0:25Sample call · appointment
The appointment is booked. You just show up.
Adam offers a free slot, books it and repeats it back to the caller. This is how the HlasAI AI receptionist will work.
Coming soon. HlasAI doesn't connect to your phone or calendar yet — until it does, that is custom work.

Adam isn't the only voice.
Adam is the HlasAI brand voice. Your line can speak with a different voice too — switch and hear the same sentence from Adam, Júlia and Alex.
All three recordings: a synthetic voice generated by artificial intelligence (ElevenLabs; voices Adam, Júlia, Alex).
The HlasAI brand voice and the line's default voice. A younger male voice, speaking naturally as in an everyday conversation.

Frequently asked questions
What does HlasAI actually do today?
It reads Slovak text aloud in a spoken voice. The samples on this page are real output — the voices Adam, Júlia and Alex. HlasAI doesn't include a phone system, SMS or calendar integration yet; the AI receptionist that answers calls is coming soon.
Will callers know they're talking to a machine?
Yes. The whole website and every sample are labelled as a synthetic voice generated by artificial intelligence. In live operation the assistant introduces itself as a voice assistant at the start of the call and doesn't pretend to be human — you can hear this directly in seven of Adam's eight samples and in the voice comparison. Article 50 of the EU Artificial Intelligence Act requires that people know when they are interacting with a machine.
Which languages do you support?
The focus is Slovak — all samples on this page are in Slovak. Other languages, Czech and Hungarian included, we first listen to together on your own text, not on the promise of a feature table.
What happens to the audio when I play a sample?
The recording plays in your browser, and its sound is broken down into frequencies there too — that's what moves the wave. Nothing is sent back to the server and nothing is recorded.
