IndexTTS Fine-tuning Demo

中文说明

This project is a demonstration of fine-tuning IndexTTS to generate speech with addtional special tags (such as <GIGGLES>), enabling the synthesis of non-textual elements like laughter.

Goals

Show you how to fine-tune IndexTTS’s text Tokenizer (BPE) and AR part (GPT2).
Support for addtional special tags like <GIGGLES> in text to generate laughter.

Fine-tuning Dataset

🤗 MrDragonFox/Elise (Modelscope mirror)

Fine-tuning Experiment Results Example

Reference Audio	Text	Synthesized Speech
Female-1	Seriously? <giggles> That’s the cutest thing I’ve ever heard!	Synthesized Speech
Female-1	真的吗？ <giggles> 这也太可爱了吧！	Synthesized Speech
Male-1	Wha—? Cute? <giggles> You think I’m cute?! Well, uh, thanks, I guess?	Synthesized Speech
Male-1	哎呀! 忘了他还在那等我们呢！<giggles> 我们两个动作得快点了！	Synthesized Speech

Modules Fine-tuned in This Project

BPE: Actually sentencepiece, this project show you how to adding new special tags such as <GIGGLES> to the text Tokenizer. See the preprocess_mel_dataset.ipynb notebook for details.
GPT2: The autoregressive model part, using the 🤗 peft library for LoRA fine-tuning, supporting the generation of speech latents for text with special tags. See the fine_tune_indextts.ipynb notebook for details.
