Regularized Entropy Information Adaptation with Temporal-Awareness Networks for Simultaneous Speech Translation

Joseph Liu, Nameer Hirschkind, Xiao Yu +1

Simultaneous Speech Translation (SimulST) requires balancing high translation quality with low latency. Recent work introduced REINA, a method that trains a Read/Write policy based…

Taxonomy-Adaptive Moderation Model with Robust Guardrails for Large Language Models

Mahesh Kumar Nandwana, Youngwan Lim, Joseph Liu +3

Large Language Models (LLMs) are typically aligned for safety during the post-training phase; however, they may still generate inappropriate outputs that could potentially pose ris…

REINA: Regularized Entropy Information-Based Loss for Efficient Simultaneous Speech Translation

Nameer Hirschkind, Joseph Liu, Xiao Yu +1

Simultaneous Speech Translation (SimulST) systems stream in audio while simultaneously emitting translated text or speech. Such systems face the significant challenge of balancing…

SmoothCache: A Universal Inference Acceleration Technique for Diffusion Transformers

Joseph Liu, Joshua Geddes, Ziyu Guo +2

Diffusion Transformers (DiT) have emerged as powerful generative models for various tasks, including image, video, and speech synthesis. However, their inference process remains co…

Enhancing Multilingual Voice Toxicity Detection with Speech-Text Alignment

Joseph Liu, Mahesh Kumar Nandwana, Janne Pylkkönen +2

Toxicity classification for voice heavily relies on the semantic content of speech. We propose a novel framework that utilizes cross-modal learning to integrate the semantic embedd…

Diffusion Synthesizer for Efficient Multilingual Speech to Speech Translation

Nameer Hirschkind, Xiao Yu, Mahesh Kumar Nandwana +9

We introduce DiffuseST, a low-latency, direct speech-to-speech translation system capable of preserving the input speaker's voice zero-shot while translating from multiple source l…
