Toroidal Probabilistic Spherical Discriminant Analysis
Anna Silnova, Niko Brümmer, Albert Swart +1
In speaker recognition, where speech segments are mapped to embeddings on the unit hypersphere, two scoring back-ends are commonly used, namely cosine scoring and PLDA. We have rec…
How to use KL-divergence to construct conjugate priors, with well-defined non-informative limits, for the multivariate Gaussian
Niko Brümmer
The Wishart distribution is the standard conjugate prior for the precision of the multivariate Gaussian likelihood, when the mean is known -- while the normal-Wishart can be used w…
The Phonexia VoxCeleb Speaker Recognition Challenge 2021 System Description
Josef Slavíček, Albert Swart, Michal Klčo +1
We describe the Phonexia submission for the VoxCeleb Speaker Recognition Challenge 2021 (VoxSRC-21) in the unsupervised speaker verification track. Our solution was very similar to…
Out of a hundred trials, how many errors does your speaker verifier make?
Niko Brümmer, Luciana Ferrer, Albert Swart
Out of a hundred trials, how many errors does your speaker verifier make? For the user this is an important, practical question, but researchers and vendors typically sidestep it a…
A Speaker Verification Backend with Robust Performance across Conditions
Luciana Ferrer, Mitchell McLaren, Niko Brummer
In this paper, we address the problem of speaker verification in conditions unseen or unknown during development. A standard method for speaker verification consists of extracting…
Large-Scale Speaker Diarization of Radio Broadcast Archives
Emre Yılmaz, Adem Derinel, Zhou Kun +4
This paper describes our initial efforts to build a large-scale speaker diarization (SD) and identification system on a recently digitized radio broadcast archive from the Netherla…
