🔥 Updates

2024/10/24: 🎉🎉🎉 We released the new Omni (MooER-omni-v1) and Speech-To-Speech Translation (MooER-S2ST-v1) models which support Mandarin input. The Omni model can hear, think and talk to you! See our demo here.
2024/09/03: We have open-sourced the training and inference code for MooER! You can follow this tutorial to train your own audio understanding model and tasks or fine-tune based on our 80k hours model.
2024/08/27: We released MooER-80K-v2 which was trained using 80K hours of data. The performance of the new model can be found below. Currently, it only supports the speech recognition task. The speech translation and the multi-task models will be released soon.

📖 Introduction

🔥 Hi there! We have updated our Omni model with the ability to listen, think and talk! Check our examples here. Please refer to the Download, Inference and Gradio Demo sections for the model usage.

The training procedure of our model is demonstrated in the following figure. We will release the training code and the technical report soon!

We introduce MooER (摩耳): an LLM-based speech recognition and translation model developed by Moore Threads. With the MooER framework, you can transcribe the speech into text (automatic speech recognition, ASR) and translate the speech into other languages (automatic speech translation, AST) in an LLM-based end-to-end manner. Some of the evaluation results of the MooER are presented in the subsequent section. More detailed experiments, along with our insights into model configurations, training strategies, etc, are provided in our technical report.

We proudly highlight that MooER is developed using Moore Threads S4000 GPUs. To the best of our knowledge, this is the first LLM-based speech model trained and inferred using entirely domestic GPUs.

🥊 Evaluation Results

We present the training data and the evaluation results below. For more comprehensive information, please refer to our report.

Training data

We utilize 5,000 hours of speech data (MT5K) to train our basic MooER-5K model. The data sources include:

Dataset	Duration
aishell2	137h
librispeech	131h
multi_cn	100h
wenetspeech	1361h
in-house data	3274h

Note that, data from the open-source datasets were randomly selected from the full training set. The in-house speech data, collected internally without transcription, were transcribed using a third-party ASR service.

Since all the above datasets were originally collected only for the speech recognition task, no translation labels are available. We leveraged a third-party machine translation service to generate pseudo-labels for translation. No data filtering techniques were applied.

At this moment, we are also developing a new model trained with 80,000 hours of speech data.

Speech Recognition

The performance of speech recognition is evaluated using word error rate (WER) and character error rate (CER).

🏁 Getting Started

🛠️ Build Environtment

Currently, only Linux is supported. Ensure that git and python are installed on your system. We recommend Python version >=3.8. It is highly recommanded to install conda to create a virtual environment.

For efficient LLM inference, GPUs should be used. For Moore Threads S3000/S4000 users, please install MUSA toolkit rc2.1.0. A docker image is also available for S4000 users. If you use other GPUs, install your own drivers/toolkits (e.g. cuda).

Build the environment with the following steps:

git clone https://github.com/MooreThreads/MooER
cd MooER

# (optional) create env using conda
conda create -n mooer python=3.8
conda activate mooer

# install the dependencies
apt update
apt install ffmpeg sox
pip install -r requirements.txt

Docker image usage for Moore Threads S4000 users is provided:

sudo docker run -it \
    --privileged \
    --name=torch_musa_release \
    --env MTHREADS_VISIBLE_DEVICES=all \
    -p 10010:10010 \
    --shm-size 80g \
    --ulimit memlock=-1 \
    mtspeech/mooer:v1.0-rc2.1.0-v1.1.0-qy2 \
    /bin/bash

# If you are nvidia user, you can try this image with cuda 11.7
sudo docker run -it \
    --privileged \
    --gpus all \
    -p 10010:10010 \
    --shm-size 80g \
    --ulimit memlock=-1 \
    mtspeech/mooer:v1.0-cuda11.7-cudnn8 \
    /bin/bash

We recommend to use an audio file shorter than 30s. The text in the audio should be less than 500 characters. It is also suggested that you convert the audio to a 16kHz 16bit mono WAV format before processing it (using ffmpeg or sox).

You can specify --server_port, --share, --server_name as needed.

Due to the lack of an HTTPS certificate, your access is limited to HTTP, for which modern browsers block the microphone access. As a workaround, you can manually grant access. For instance, in Chrome, navigate to chrome://flags/#unsafely-treat-insecure-origin-as-secure and add the target address to the whitelist. For other browsers, please google for a similar workaround.

In the demo, using the streaming mode will yield faster results. However, please note that the beam size is restricted to be 1 in the streaming mode, which may slightly degrade the performance.

🤔 No experience about how to run Gradio?

💻 Don't have a machine to run the demo?

⌛ Don't have time to install the dependencies?

☕ Just take a coffee and click here to try our online demo. It is running on a Moore Threads S4000 GPU server!
