SpeakerCard-1M: An Evidence-Grounded Corpus for In-the-Wild Speaker Verification

Junyi Peng, Oldřich Plchot, Xiao Song +9

Modern speaker verification (SV) systems rely on speaker embeddings that are effective but difficult to interpret or query in natural language. Most existing speech-text corpora ta…

Grounding Spoken LLMs in Multi-Speaker Audio via Diarization Conditioning

Alexander Polok, Samuele Cornell, Sathvik Udupa +3

We propose diarization-conditioned spoken language models (SLMs), a strategy for extending SLMs to far-field multi-talker audio. Rather than adapting the decoder via Serialized Out…

State-of-the-art Embeddings with Video-free Segmentation of the Source VoxCeleb Data

Sara Barahona, Ladislav Mošner, Themos Stafylakis +4

In this paper, we refine and validate our method for training speaker embedding extractors using weak annotations. More specifically, we use only the audio stream of the source Vox…

Hybrid Pruning: In-Situ Compression of Self-Supervised Speech Models for Speaker Verification and Anti-Spoofing

Junyi Peng, Lin Zhang, Jiangyu Han +5

Although large-scale self-supervised learning (SSL) models like WavLM have achieved state-of-the-art performance in speech processing, their significant size impedes deployment on…

DeCRED: Decoder-Centric Regularization for Encoder-Decoder Based Speech Recognition

Alexander Polok, Santosh Kesiraju, Karel Beneš +3

This paper presents a simple yet effective regularization for the internal language model induced by the decoder in encoder-decoder ASR models, thereby improving robustness and gen…

BUT System for the MLC-SLM Challenge

Alexander Polok, Jiangyu Han, Dominik Klement +3

We present a two-speaker automatic speech recognition (ASR) system that combines DiCoW -- a diarization-conditioned variant of Whisper -- with DiariZen, a diarization pipeline buil…
