XTTS

🧠 XTTS in SkyrimNet — the Default-Quality TTS​

XTTS (Cross-lingual Text-to-Speech) is a powerful, deep-learning-based TTS engine that brings realistic, emotionally expressive, and cloneable voices to Skyrim. Unlike simpler TTS engines, XTTS can replicate a specific voice from a short audio clip, making it ideal for immersive, character-specific dialogue in modded Skyrim.

In SkyrimNet, XTTS is used via a local HTTP endpoint, making it easy to integrate and fast enough for real-time use.
It’s currently considered the default voice generation system in SkyrimNet, especially for voice cloning good emotional fidelity. and low latency.

🎙️ What XTTS Does​

XTTS converts any input text into high-quality, expressive speech — optionally mimicking a specific voice using a voice reference sample.

Input:
Text: "You're not from around here, are you?"
Voice sample: 10-second clip of a female Nord NPC

Output:
High-fidelity audio of that line, spoken in the same voice and tone as the sample

XTTS produces rich, natural speech, with subtle pauses, intonation, and personality — perfect for Skyrim’s varied characters.

🌐 How XTTS Works in SkyrimNet​

XTTS is not currently embedded into SkyrimNet like Piper — instead, it runs as a separate local TTS service, typically on:

http://localhost:8002

Here’s how SkyrimNet uses it:

  1. SkyrimNet sends a request to the XTTS server with:

    • The text to speak
    • Optional voice reference audio
    • Optional speaker ID or emotion hints

  2. XTTS returns a fully rendered WAV or PCM audio clip

  3. SkyrimNet plays the audio in-game, synced with dialogue

This architecture keeps SkyrimNet lightweight while still offering powerful voice features via XTTS.
