SeamlessM4T

SeamlessM4T is designed to provide high quality translation, allowing people from different linguistic communities to communicate effortlessly through speech and text.

SeamlessM4T covers:

  • 📥 101 languages for speech input.
  • ⌨️ 96 Languages for text input/output.
  • 🗣️ 35 languages for speech output.

This unified model enables multiple tasks without relying on multiple separate models:

  • Speech-to-speech translation (S2ST)
  • Speech-to-text translation (S2TT)
  • Text-to-speech translation (T2ST)
  • Text-to-text translation (T2TT)
  • Automatic speech recognition (ASR)

Quick Start

Installation

pip install .

A temporary extra requirement for fairseq2 is libsndfile. From Conda environment it can be installed via:

conda install -y -c conda-forge libsndfile

At this point fairseq2 has a confirmed support only for Linux and macOS. Pre-built packages are only available for Linux (macOS is planned).

Running inference

Here’s an example of using the CLI from the root directory to run inference.

S2ST task:

m4t_predict <path_to_input_audio> s2st <tgt_lang> --output_path <path_to_save_audio>

T2TT task:

m4t_predict <input_text> t2tt <tgt_lang> --src_lang <src_lang>

Please refer to the inference README for detailed instruction on how to run inference.

Docker

Here’s how you run Seamless Communication on Docker for Windows

Build:

.\build.bat

Running inference:

.\run.bat

Please refer to the inference README for detailed instruction on how to run inference.

Libraries

Seamless Communication depends on 3 libraries developed by Meta.

fairseq2 is our next-generation open-source library of sequence modeling components that provides researchers and developers with building blocks for machine translation, language modeling, and other sequence generation tasks. All SeamlessM4T models in this repository are powered by fairseq2.

SONAR, Sentence-level multimOdal and laNguage-Agnostic Representations is a new multilingual and -modal sentence embedding space which outperforms existing sentence embeddings such as LASER3 and LabSE on the xsim and xsim++ multilingual similarity search tasks. SONAR provides text and speech encoders for many languages. SeamlessAlign was mined based on SONAR embeddings.

BLASER 2.0 is our latest model-based evaluation metric for multimodal translation. It is an extension of BLASER, supporting both speech and text. It operates directly on the source signal, and as such, does not require any intermediate ASR system like ASR-BLEU. As in the first version, BLASER 2.0 leverages the similarity between input and output sentence embeddings. SONAR is the underlying embedding space for BLASER 2.0. Scripts to run evaluation with BLASER 2.0 can be found in the SONAR repo.

As part of the seamless communication project, we've extended the stopes library. Version 1 provided a text-to-text mining tool to build training dataset for translation models. Version 2 has been extended thanks to SONAR, to support tasks around training large speech translation models. In particular, we provide tools to read/write the fairseq audiozip datasets and a new mining pipeline that can do speech-to-speech, text-to-speech, speech-to-text and text-to-text mining, all based on the new SONAR embedding space.

Resources and usage

SeamlessM4T models

Model Name #params checkpoint metrics
SeamlessM4T-Large 2.3B 🤗 Model card - checkpoint metrics
SeamlessM4T-Medium 1.2B 🤗 Model card - checkpoint metrics

We provide the extensive evaluation results of seamlessM4T-Large and SeamlessM4T-Medium reported in the paper (as averages) in the metrics files above.

Evaluating SeamlessM4T models

To reproduce our results, or to evaluate using the same metrics over your own test sets, please check out the README here.

Finetuning SeamlessM4T models

Please check out the README here.

Converting raw audio to units

Please check out the README here.

On-device models

Apart from Seamless-M4T large (2.3B) and medium (1.2B) models, we are also releasing a small model (281M) targeted for on-device inference. To learn more about the usage and model details check out the README here.

SeamlessAlign mined dataset

We open-source the metadata to SeamlessAlign, the largest open dataset for multimodal translation, totaling 270k+ hours of aligned Speech and Text data. The dataset can be rebuilt by the community based on the SeamlessAlign readme.
