Wriothesley — Qwen3-TTS-0.6B LoRA Model

A Qwen3-TTS LoRA fine-tune that reproduces Wriothesley's voice (English Only) from Genshin Impact.

[!IMPORTANT] Fan-made model. Wriothesley and Genshin Impact are © miHoYo / HoYoverse. This model is a non-official fan work for research/education purposes and is not affiliated with or endorsed by HoYoverse.

Model Description

This is a LoRA adapter fine-tune of Qwen/Qwen3-TTS-12Hz-0.6B-Base aimed at reproducing the voice of Wriothesley (Genshin Impact).

Two ways to use it:

Route	What you need	Reference audio?
A. Fine-tuned checkpoint + adapter (this repo, root)	The full model in this repo	❌ Not needed — the character's reference audio is baked into the state dict during training
B. Base model + adapter	`Qwen/Qwen3-TTS` + this repo's `adapter/` folder	✅ Required — pass any example clip of the character

Usage

Using Model provided with this repo

import torch
import soundfile as sf
from qwen_tts import Qwen3TTSModel

device = "cuda:0"
tts = Qwen3TTSModel.from_pretrained(
    "./Wriothesley-LoRA-16",
    device_map=device,
    dtype=torch.bfloat16,
    attn_implementation="flash_attention_2", # use sdpa if flash-attn is not installed
)

from peft import PeftModel

tts.model = PeftModel.from_pretrained(
    tts.model,
    "./Wriothesley-LoRA-16/adapter"
)

wav, sr = tts.generate_custom_voice(
    text = "Word of advice: Don't break the law. Hmm, is there anything else? Oh, yeah... Seriously, don't break the law.",
    speaker = "Wriothesley"
)

sf.write("output.wav", wavs[0], sr)

Using the Base Qwen/Qwen3-TTS-12Hz-0.6B model

import torch
import soundfile as sf
from qwen_tts import Qwen3TTSModel

tts = Qwen3TTSModel.from_pretrained(
    "Qwen/Qwen3-TTS-12Hz-0.6B-Base",
    device_map="cuda:0",
    dtype=torch.bfloat16,
    attn_implementation="flash_attention_2", # use sdpa if flash-attn is not installed
)

from peft import PeftModel

tts.model = PeftModel.from_pretrained(
    tts.model,
    "./Wriothesley-LoRA-16/adapter"
)

ref_audio = "path_to_Wriothesley_voiceline"   # Can see https://huggingface.co/datasets/rijulpaul/pano30qx/viewer/Wriothesley
ref_text  = "voiceline_transcription"

wavs, sr = model.generate_voice_clone(
    text="I am solving the equation: x = [-b ± √(b²-4ac)] / 2a? Nobody can — it's a disaster (◍•͈⌔•͈◍), very sad!",
    language="English",
    ref_audio=ref_audio,
    ref_text=ref_text,
)

# Save the resulting audio
sf.write("output_voice_clone.wav", wavs[0], sr)
