## 💡 Highlights

- 💪 **Built on Llama-3.1-8B-Instruct, ensuring high-quality responses.**

- 🚀 **Low-latency speech interaction with a latency as low as 226ms.**

- 🎧 **Simultaneous generation of both text and speech responses.**

- ♻️ **Trained in less than 3 days using just 4 GPUs.**

## Install

1. Clone this repository.

```shell
git clone https://github.com/ictnlp/LLaMA-Omni
cd LLaMA-Omni
```

2. Install packages.

```shell
conda create -n llama-omni python=3.10
conda activate llama-omni
pip install pip==24.0
pip install -e .
```

3. Install `fairseq`.

```shell
git clone https://github.com/pytorch/fairseq
cd fairseq
pip install -e . --no-build-isolation
```

4. Install `flash-attention`.

```shell
pip install flash-attn --no-build-isolation
```

## Quick Start

1. Download the `Llama-3.1-8B-Omni` model from 🤗[Huggingface](https://huggingface.co/ICTNLP/Llama-3.1-8B-Omni). 

2. Download the `Whisper-large-v3` model.

```shell
import whisper
model = whisper.load_model("large-v3", download_root="models/speech_encoder/")
```

3. Download the unit-based HiFi-GAN vocoder.

```shell
wget https://dl.fbaipublicfiles.com/fairseq/speech_to_speech/vocoder/code_hifigan/mhubert_vp_en_es_fr_it3_400k_layer11_km1000_lj/g_00500000 -P vocoder/
wget https://dl.fbaipublicfiles.com/fairseq/speech_to_speech/vocoder/code_hifigan/mhubert_vp_en_es_fr_it3_400k_layer11_km1000_lj/config.json -P vocoder/
```

## Gradio Demo

1. Launch a controller.
```shell
python -m omni_speech.serve.controller --host 0.0.0.0 --port 10000
```

2. Launch a gradio web server.
```shell
python -m omni_speech.serve.gradio_web_server --controller http://localhost:10000 --port 8000 --model-list-mode reload --vocoder vocoder/g_00500000 --vocoder-cfg vocoder/config.json
```

3. Launch a model worker.
```shell
python -m omni_speech.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path Llama-3.1-8B-Omni --model-name Llama-3.1-8B-Omni --s2s
```

4. Visit [http://localhost:8000/](http://localhost:8000/) and interact with LLaMA-3.1-8B-Omni!

**Note: Due to the instability of streaming audio playback in Gradio, we have only implemented streaming audio synthesis without enabling autoplay. If you have a good solution, feel free to submit a PR. Thanks!**

## Local Inference

To run inference locally, please organize the speech instruction files according to the format in the `omni_speech/infer/examples` directory, then refer to the following script.
```shell
bash omni_speech/infer/run.sh omni_speech/infer/examples
```
