# IndexTTS-1.5 ONNX

This repository provides an ONNX export of `IndexTeam/IndexTTS-1.5`.

Original model:

https://huggingface.co/IndexTeam/IndexTTS-1.5

Original project:

https://github.com/index-tts/index-tts

This is not an official IndexTTS release. It is intended for ONNX Runtime inference testing and deployment experiments.

This model used by https://github.com/mercallureAI/local-multimodal-infra

## Description

The models in this repository were exported from the original `IndexTTS-1.5` PyTorch weights to ONNX format, making them easier to use with ONNX Runtime and other ONNX-compatible inference backends.

This ONNX version is mainly intended for inference deployment and compatibility testing. A complete TTS pipeline may still require additional preprocessing, text processing, audio processing, and post-processing logic.
