Research Voicebox for local voice cloning

## Context
Carlo wants to evaluate [Voicebox](https://github.com/jamiepine/voicebox) as a local voice-cloning option that can run on his own hardware.

## Why it matters
If this works well, it could provide a self-hosted path for voice cloning and local speech generation without sending audio to a cloud service.

## Proposed next step
Check whether Voicebox fits a home-lab workflow, confirm the hardware and dependency requirements, and identify any integration path that would make it useful for the existing setup.

Start with the linked Voicebox repository and its overview and Docker documentation. Confirm the hardware and dependency requirements, assess whether it fits a home-lab workflow, and document a viable integration path for the existing setup.
