Deda Mraz is calling: Santa talks to children in Serbia, voiced by a Dialogist agent

Deda Mraz zove («Деда Мраз зове») is our New Year 2027 project for families in Serbia: a conversation with Deda Mraz for your child. Parents send a photo of the letter and a few words about the child, and Deda Mraz talks with the child in Serbian, in the browser or by phone. The project lives at deda.dialogist.cc.

How it works

1. A parent writes to Deda Mraz. A photo of the child’s letter and a short note: the child’s name, what they hope for, what Deda Mraz should know.
2. Deda Mraz reads it. He knows only what the parent told him. In the project’s own words: «Деда зна само оно што сте му рекли» (Deda knows only what you told him).
3. The child talks to Deda Mraz. Right away in the browser, with no phone needed, or by phone with a five-digit code. The conversation lasts a few minutes, in Serbian.

It is free, with no app and no account.

Built for children, and for parents

• No audio is recorded.
• The letter photo is read and not kept.
• Deda Mraz does not ask for a surname, an address or a school.
• A safety system screens every note before a call.
• Phone numbers are kept only as an irreversible fingerprint (a hash).
• Calls run at sensible hours, from 9:00 to 20:30, and last ten minutes at most.
• The parent’s note is kept for up to 21 days after the last edit, and until 15 January 2027 at the latest. Parents can delete it themselves.
• The text of the conversation stays in the call log until 15 January 2027 at the latest, then it is deleted. We do not use it to train models.
• Deda Mraz is a voice AI agent, and the project site tells parents so.

What it shows about Dialogist

Deda Mraz is a Dialogist agent like any other, on the same stack our customers get:

• Serbian, in and out. Oasis Speech hears Serbian at the top grade (see Languages), and the agent speaks with a natural Serbian voice.
• Calls from the browser. A child can talk to Deda Mraz from a laptop or a phone browser, without dialling, over the same real-time voice engine as a phone call.
• Context before the first word. Deda Mraz opens the call already knowing the child’s name and the letter, the way a business agent opens with the customer’s record.
• Interruptions. Children talk over Santa, and he lets them: the agent handles interruptions and the end of each turn as in any Dialogist call.
