Show HN: Podvoice – Local-first CLI to turn Markdown into multi-speaker audio

Hi HN,

I built Podvoice because I wanted a simple way to turn Markdown podcast-style scripts into audio without relying on cloud TTS APIs.

It runs fully locally using Coqui XTTS v2. No API keys. No accounts. Just a CLI workflow.

You write something like:

[Host | calm] Hello and welcome.

[Guest | excited] Let’s talk about AI.

And it generates a single stitched audio file.

Would love feedback on the idea, UX, or use cases I might be missing.
