Meta introduces Omnilingual ASR, a cutting-edge suite of models enhancing automatic speech recognition for over 1,600 languages, leveraging extensive multilingual datasets.
Meta has unveiled its Omnilingual Automatic Speech Recognition (ASR) system, a groundbreaking suite designed to bolster speech recognition capabilities across more than 1,600 languages. This ambitious project, announced by Meta AI, aims to expand the reach and accuracy of speech technology, providing a critical tool for linguists and developers worldwide.
Comprehensive Language Coverage
The Omnilingual ASR suite is built on the foundation of Meta’s previous research and offers a variety of models, from lightweight 300-million parameter versions suitable for low-power devices to robust 7-billion parameter models that deliver high accuracy. The initiative includes the general-purpose speech model wav2vec 2.0, available in multiple sizes, which researchers and developers can use to tackle a wide range of speech-related tasks.
Open Source and Collaborative Framework
All these models and datasets are released under the permissive Apache 2.0 license, with data provided under the CC-BY license, ensuring broad accessibility. The initiative is based on the open-source fairseq2 framework, empowering users to develop tailored speech solutions using the latest tools in the PyTorch ecosystem.
Expansive and Diverse Training Corpus
Omnilingual ASR’s training corpus is one of the largest ever assembled, combining publicly available datasets with community-sourced speech recordings. Meta collaborated with local organizations to recruit native speakers, often in remote regions, to ensure a diverse linguistic representation. This effort has resulted in the largest ultra-low-resource spontaneous ASR dataset, covering hundreds of previously unsupported languages.
Global Partnerships and Community Engagement
Through the Language Technology Partner Program, Meta has partnered with linguists, researchers, and language communities worldwide. Collaborations with organizations like Mozilla Foundation’s Common Voice and Lanfrica/NaijaVoices have infused the project with crucial linguistic and cultural insights, ensuring it meets local needs and empowers language communities globally.
Meta’s Omnilingual ASR represents a significant leap forward in speech recognition technology, promising to enhance communication and accessibility for diverse linguistic communities around the globe. For more details, visit the Meta AI blog.
