DiaCorrect: Error Correction Back-end For Speaker Diarization

1 code implementation15 Sep 2023 Jiangyu Han, Federico Landini, Johan Rohdin, Mireia Diez, Lukas Burget, Yuhang Cao, Heng Lu, Jan Cernocky

In this work, we propose an error correction framework, named DiaCorrect, to refine the output of a diarization system in a simple yet effective way.

Speaker embeddings by modeling channel-wise correlations

1 code implementation6 Apr 2021 Themos Stafylakis, Johan Rohdin, Lukas Burget

Speaker embeddings extracted with deep 2D convolutional neural networks are typically modeled as projections of first and second order statistics of channel-frequency pairs onto a linear layer, using either average or attentive pooling along the time axis.

Probabilistic embeddings for speaker diarization

1 code implementation6 Apr 2020 Anna Silnova, Niko Brümmer, Johan Rohdin, Themos Stafylakis, Lukáš Burget

We apply the proposed probabilistic embeddings as input to an agglomerative hierarchical clustering (AHC) algorithm to do diarization in the DIHARD'19 evaluation set.

Detecting Spoofing Attacks Using VGG and SincNet: BUT-Omilia Submission to ASVspoof 2019 Challenge

no code implementations13 Jul 2019 Hossein Zeinali, Themos Stafylakis, Georgia Athanasopoulou, Johan Rohdin, Ioannis Gkinis, Lukáš Burget, Jan "Honza'' Černocký

In this paper, we present the system description of the joint efforts of Brno University of Technology (BUT) and Omilia -- Conversational Intelligence for the ASVSpoof2019 Spoofing and Countermeasures Challenge.

Self-supervised speaker embeddings

no code implementations6 Apr 2019 Themos Stafylakis, Johan Rohdin, Oldrich Plchot, Petr Mizera, Lukas Burget

Contrary to i-vectors, speaker embeddings such as x-vectors are incapable of leveraging unlabelled utterances, due to the classification loss over training speakers.
