MODULE 06 · INCLUDED IN FOUNDATIONS

The voice: text-to-speech

What this module is

Which text-to-speech engine to use, how to wire it so the avatar and the stream hear the same audio, and the small tricks that make a synthetic voice feel alive.

What you'll build

A locked-in character voice
Audio routed through a virtual cable so lip-sync never drifts
30–50 pre-rendered stock lines that cover latency gaps

Lessons

01Choosing an engine (Kokoro, Chatterbox, ElevenLabs, hosted alternatives)
02Wiring it up
03Making it sound alive

Checkpoint

The character speaks a reply through the virtual cable, and you can hear it in OBS's audio mixer.

The engine comparison with real per-hour costs

This section contains the full written walkthrough for this part of the module.

It includes the step-by-step instructions, the settings to change, and the reasoning behind each choice.

Screenshots and short clips show exactly what the screen should look like at every stage.

The commands and configuration files are provided in full so you can copy them directly.

Common failure points are listed with the fix for each one, in the order you are likely to hit them.

A short recap closes the section with the one thing that must be working before you move on.

Everything here is tested on the reference build before it is published to the program.
