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

News · 2026-10-27 · Dialogist team

> This New Year, Deda Mraz talks with children in Serbia in Serbian, in the browser or by phone. Free of charge, run on Dialogist's voice stack.

**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](https://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](/en/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.
