OpenBEATs-ICME-SOUND

OpenBEATs-ICME-SOUND

This model is part of the CMU-AIST submission for the ICME 2025 Audio Encoder Challenge. It is a scaled-up version of the BEATs (audio encoder) architecture, featuring 300 million parameters.

• Paper: The CMU-AIST submission for the ICME 2025 Audio Encoder Challenge
• Library: espnet

Model Description

The system is built on BEATs, a masked speech token prediction-based audio encoder. This checkpoint was trained on 74,000 hours of diverse audio data covering speech, music, and sound corpora. It explores the impact of balanced pre-training mixtures on final performance across various audio domains.

ESPnet2 SSL model

shikhar7ssu/OpenBEATs-ICME-SOUND

This model was trained by Shikhar Bharadwaj using as2m recipe in espnet.
