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…

Streaming Sortformer: Speaker Cache-Based Online Speaker Diarization with Arrival-Time Ordering

Ivan Medennikov, Taejin Park, Weiqing Wang +5

This paper presents a streaming extension for the Sortformer speaker diarization framework, whose key property is the arrival-time ordering of output speakers. The proposed approac…

META-CAT: Speaker-Informed Speech Embeddings via Meta Information Concatenation for Multi-talker ASR

Jinhan Wang, Weiqing Wang, Kunal Dhawan +7

We propose a novel end-to-end multi-talker automatic speech recognition (ASR) framework that enables both multi-speaker (MS) ASR and target-speaker (TS) ASR. Our proposed model is…
