**BengaliStoryTeller** is a free, offline AI storyteller that reads Bengali stories aloud to children in a calm, natural voice, right from a normal laptop.

**The problem:** After a long, tiring day at work, many parents still hear the same request at bedtime: *"Tell me a story!"* But they're exhausted, short on time, and have often already told every story they know. Bengali-speaking families also have very few storytelling or AI voice tools in **their own language**, since most are built for English.

**How it helps:** BengaliStoryTeller takes a Bengali story and reads it aloud sentence by sentence, with natural pauses like a real storyteller. Parents get a helping hand on busy or tiring days, and children still get their bedtime story in their mother tongue. It needs no internet, no GPU, and no subscription.

You come home tired after a long day at work, and your child asks, "Tell me a story!" Most nights you're too tired to make up something new, and the same old stories get boring.

Bengali Story Teller fixes that. Run one command and it:

The stories are scary enough to be fun, and every one…

BengaliStoryTeller runs fully offline on a CPU-only Ubuntu laptop, with no cloud APIs and no GPU.

**Model:** Meta's open-weight **`facebook/mms-tts-ben`** (MMS text-to-speech for Bengali) from Hugging Face. It's small (~145 MB) and fast on a normal CPU. I first tried a larger Coqui Bengali model (~900 MB) but preferred how MMS sounded.

**Stack:** Python, Transformers, PyTorch (CPU), NumPy, and soundfile.

Without open models, this project wouldn't exist. Most closed TTS APIs offer limited Bengali support, charge per character, and need the internet, which is a poor fit for a bedtime story tool used every night.

Because MMS is open-weight, I could:

Meta trained MMS on over 1,000 languages so that smaller language communities aren't left behind. Open innovation let me take that work and turn it into something useful for Bengali-speaking kids and their parents.

This project started at home. When we were kids, my elder sister would go to our parents every single night and ask for a story: sometimes a **bhuter golpo (ghost story)**, sometimes a story about **raja and rani** (king and queen). But after a whole day of work, our parents were often just too tired to tell one.

That memory stayed with me. Those stories are how so many Bengali children grow up: scared of ghosts, dreaming of kings and queens, and quietly learning their language along the way.

The first time my laptop read a full Bengali story out loud, pausing after every `।` like a real storyteller, I thought of my sister waiting for her story. BengaliStoryTeller is for every child like her, and every tired parent like mine, so the bedtime story never has to be skipped.
