Defining and Measuring Disentanglement for non-Independent Factors of Variation

no code implementations13 Aug 2024 Antonio Almudévar, Alfonso Ortega, Luis Vicente, Antonio Miguel, Eduardo Lleida

In this paper we give a definition of disentanglement based on information theory that is also valid when the factors of variation are not independent.

Predefined Prototypes for Intra-Class Separation and Disentanglement

no code implementations23 Jun 2024 Antonio Almudévar, Théo Mariotte, Alfonso Ortega, Marie Tahon, Luis Vicente, Antonio Miguel, Eduardo Lleida

Prototypical Learning is based on the idea that there is a point (which we call prototype) around which the embeddings of a class are clustered.

Improved Vocal Effort Transfer Vector Estimation for Vocal Effort-Robust Speaker Verification

no code implementations3 May 2023 Iván López-Espejo, Santi Prieto, Alfonso Ortega, Eduardo Lleida

Despite the maturity of modern speaker verification technology, its performance still significantly degrades when facing non-neutrally-phonated (e. g., shouted and whispered) speech.

Class Token and Knowledge Distillation for Multi-head Self-Attention Speaker Verification Systems

no code implementations6 Nov 2021 Victoria Mingote, Antonio Miguel, Alfonso Ortega, Eduardo Lleida

This paper explores three novel approaches to improve the performance of speaker verification (SV) systems based on deep neural networks (DNN) using Multi-head Self-Attention (MSA) mechanisms and memory layers.

Generalizing AUC Optimization to Multiclass Classification for Audio Segmentation With Limited Training Data

no code implementations27 Oct 2021 Pablo Gimeno, Victoria Mingote, Alfonso Ortega, Antonio Miguel, Eduardo Lleida

Area under the ROC curve (AUC) optimisation techniques developed for neural networks have recently demonstrated their capabilities in different audio and speech related tasks.

Shouted Speech Compensation for Speaker Verification Robust to Vocal Effort Conditions

no code implementations6 Aug 2020 Santi Prieto, Alfonso Ortega, Iván López-Espejo, Eduardo Lleida

These compensation techniques are borrowed from the area of robustness for automatic speech recognition and, in this work, we apply them to compensate the mismatch between shouted and normal conditions in speaker verification.

Tied Hidden Factors in Neural Networks for End-to-End Speaker Recognition

no code implementations27 Dec 2018 Antonio Miguel, Jorge Llombart, Alfonso Ortega, Eduardo Lleida

As in Joint Factor Analysis, the model uses tied hidden variables to model speaker and session variability and a MAP adaptation of some of the parameters of the model.

Differentiable Supervector Extraction for Encoding Speaker and Phrase Information in Text Dependent Speaker Verification

no code implementations22 Dec 2018 Victoria Mingote, Antonio Miguel, Alfonso Ortega, Eduardo Lleida

Moreover, we can apply a convolutional neural network as front-end, and thanks to the alignment process being differentiable, we can train the whole network to produce a supervector for each utterance which will be discriminative with respect to the speaker and the phrase simultaneously.
