Meta SeamlessM4T was actually developed by a dedicated team of researchers and engineers right here at Meta. Some of the key people involved in this project included Bapi Akula, Pierre Andrews, and Loïc Barrault, among many others. It was a real collaborative effort to build a foundational model that could handle both speech and text translation across many languages and tasks. They’re really committed to open science, which is why they’ve made the model publicly available under the CC BY-NC 4.0 license. They also released a huge dataset called SeamlessAlign. The model’s architecture, which they call multitask UnitY, is designed to tackle various translation jobs, like recognizing speech, translating text, and even synthesizing speech, all for a wide range of languages.
Using SeamlessM4T is pretty straightforward if you follow these steps:
