IndexTTS2: A Breakthrough in Emotionally Expressive and Duration-Controlled Auto-Regressive Zero-Shot Text-to-Speech

IndexTTS

A Windows-focused deployment of the IndexTTS project, using a Conda environment for dependency management instead of the UV. This setup is specifically designed for users running Windows with an NVIDIA GPU.

Note: This project is a modified setup of the original IndexTTS repository. All credit for the core model and research goes to the original authors.

🚀 Key Changes from Official Setup

Conda Environment: Uses Anaconda for managing Python packages and dependencies, which is a familiar tool for many Windows users in the ML community.

Using Modelscope download reather than hf

create conda env:

conda create -n index-tts -y python=3.10
conda activate index-tts
conda install -c conda-forge ffmpeg

clone project and setup env Note: because 'pip install torch' will install cpu version now We use '-f https://mirrors.aliyun.com/pytorch-wheels/youcudaversion' find gpu version torch use

git clone https://github.com/NoahBishop/index-tts.git
cd index-tts
pip install torch -f https://mirrors.aliyun.com/pytorch-wheels/cu126/
pip install torchaudio -f https://mirrors.aliyun.com/pytorch-wheels/cu126/
pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host=mirrors.aliyun.com
