# Ming-UniAudio

<p align="center">📑 <a href="https://mdn.alipayobjects.com/cto_asrtts/uri/file/as/TR-Ming-UniAudio.pdf">Technical Report</a>｜📖<a href="https://xqacmer.github.io/Ming-Unitok-Audio.github.io/">Project Page</a> ｜🤗 <a href="https://huggingface.co/inclusionAI/Ming-UniAudio-16B-A3B">Hugging Face</a>｜ 🤖 <a href="https://modelscope.cn/models/inclusionAI/Ming-UniAudio-16B-A3B">ModelScope</a>



## Introduction

Ming-UniAudio is a novel framework that unifies speech understanding, generation, and editing. Its core is a unified continuous speech tokenizer that effectively unifies semantic and acoustic features within an end-to-end model. We developed a speech language model that strikes a balance between generation and understanding capabilities based on the unified continuous audio tokenizer. Leveraging this foundational model, which exhibits robust performance in both domains, we further trained a dedicated speech editing model built upon [Ming-Lite-Omni](https://github.com/inclusionAI/Ming). Crucially, Ming-UniAudio is the first to enable universal, free-form speech editing guided solely by natural language instructions, handling complex semantic and acoustic modifications without manual region specification.

- 🔥 First unified continuous speech tokenizer for both understanding and generation tasks: [MingTok-Audio](https://github.com/inclusionAI/MingTok-Audio)
- 🔥 First Speech LLM  with unifed continuous tokenizer for both understanding and generation: [Ming-UniAudio](https://huggingface.co/inclusionAI/Ming-UniAudio-16B-A3B)
- 🔥 First universal free-form speech editing model for various semantic and acoustic editing task without timestamp condition: [Ming-UniAudio-Edit](https://huggingface.co/inclusionAI/Ming-UniAudio-16B-A3B-Edit)
- 🔥 First benchmark for free-form speech editing: [Ming-Freeform-Audio-Edit-Benchmark](https://huggingface.co/datasets/inclusionAI/Ming-Freeform-Audio-Edit-Benchmark)

## 📌 Updates

* [2025.09.30] 🔥 We release [Ming-UniAudio](https://xqacmer.github.io/Ming-Unitok-Audio.github.io/) with significant improvements across speech understanding, generation, and free-form editing tasks.


## Key Features
Ming-UniAudio features key optimizations as follows, compared to other audio-assisted LLMs:
- **Unified Continuous Speech Tokenizer**: Ming-UniAudio proposes a unified continuous speech tokenizer [MingTok-Audio](https://github.com/inclusionAI/MingTok-Audio) based on a VAE framework with a causal Transformer architecture, the first continuous speech tokenizer to effectively integrate semantic and acoustic features, and enables a closed-loop system with LLMs through hierarchical feature representations, makes it suitable for both understanding and generation tasks

- **Unified Speech Language Model for Generation and Understanding**: We pretrain an end-to-end unified speech language model with a single LLM backbone for both understanding and generation tasks, enhanced with a Diffusion Head to ensure high-fidelity speech synthesis.
- **Instruction-Guided Free-Form Speech Editing**: We introduce the first instruction-guided, free-form speech editing framework that supports comprehensive semantic and acoustic edits without requiring explicit edit regions, along with [Ming-Freeform-Audio-Edit](https://huggingface.co/datasets/inclusionAI/Ming-Freeform-Audio-Edit-Benchmark), the first open-source evaluation set for such tasks.

##  Evaluation
In various benchmark tests, Ming-UniAudio demonstrates highly competitive results compared to industry-leading models of similar scale.

## Use Cases

Additional demonstration cases are available on our project [page](https://xqacmer.github.io/Ming-Unitok-Audio.github.io/).


## Environment Preparation


### Installation with pip
```shell
pip install -r requirements.txt
```

### Installation with docker

You can also initialize the environment by building the docker image. First clone this repository:
```shell
git clone --depth 1 https://github.com/inclusionAI/Ming-UniAudio
cd Ming-UniAudio
```
Then build the docker image with the provided Dockerfile in `docker/docker-py310-cu121`. This step might take a while:
```shell
docker build -t ming:py310-cu121 docker/docker-py310-cu121
```
At last, start the container with the current repo directory mounted:
```shell
docker run -it --gpus all -v "$(pwd)":/workspace/Ming-UniAudio ming:py310-cu121 ming:py310-cu121 /bin/bash
```
You can run the model with python interface. You may download the huggingface model in the repo directory first (`.../Ming-UniAudio/`) or mount the downloaded model path when starting the container.
