OmniSONAR-200 establishes a state-of-the-art embedding space for 200 languages, integrating code and math. It uses an LLM-initialized Encoder-Decoder, token-level decoding, a novel split-softmax contrastive loss, and synthetic hard negatives.
The model extends to thousands of language varieties via teacher-student distillation, using hybrid MSE and contrastive loss, projecting new languages into the existing space.
OmniSONAR-speech integrates 177 spoken languages into the shared semantic space through distillation, aligning spoken sentences with their transcriptions.
