Discrete Diffusion for Generative Modeling of Text-Aligned Speech Tokens

Pin-Jui Ku, He Huang, Jean-Marie Lemercier +3

This paper introduces a discrete diffusion model (DDM) framework for text-aligned speech tokenization and reconstruction. By replacing the auto-regressive speech decoder with a dis…

TalkVid: A Large-Scale Diversified Dataset for Audio-Driven Talking Head Synthesis

Shunian Chen, Hejin Huang, Yexin Liu +10

Audio-driven talking head synthesis has achieved remarkable photorealism, yet state-of-the-art (SOTA) models exhibit a critical failure: they lack generalization to the full spectr…

Speaker Targeting via Self-Speaker Adaptation for Multi-talker ASR

Weiqing Wang, Taejin Park, Ivan Medennikov +6

We propose a self-speaker adaptation method for streaming multi-talker automatic speech recognition (ASR) that eliminates the need for explicit speaker queries. Unlike conventional…

Word Level Timestamp Generation for Automatic Speech Recognition and Translation

Ke Hu, Krishna Puvvada, Elena Rastorgueva +7

We introduce a data-driven approach for enabling word-level timestamp prediction in the Canary model. Accurate timestamp information is crucial for a variety of downstream tasks su…
