* * *

### 🥈 Dia TTS — Best Voice Quality (Sounds Scary Real)

> **What is it?**
>
> A 1.6 billion parameter AI model specifically built to generate realistic conversations. You give it a script with `[S1]` and `[S2]` tags, it gives you audio that sounds like two humans talking.

> **Why it's insane**
>
> - **One-pass generation** — whole conversation rendered at once, not stitched together
> - Built-in reactions: `(laughs)`, `(sighs)`, `(coughs)`, `(clears throat)`
> - Clone any voice from a few seconds of audio
> - Apache 2.0 license
> - 19,000+ stars — people are obsessed

> **Example script**
>
> ```auto
> [S1] Welcome to the show! 
> [S2] Thanks for having me. (laughs) 
> [S1] So let's talk about why AI is eating the world.
> [S2] (sighs) Where do we even start...
> 
> ```
> 
> Feed that in → get a podcast clip out.

> **Hardware needs**
>
> - ~10GB GPU memory (RTX 3070+ or similar)
> - Runs at 40 tokens/second on an A4000
> - No GPU? Use the free HuggingFace demo
