Exploratory Evaluation of Speech Content Masking

no code implementations8 Jan 2024 Jennifer Williams, Karla Pizzi, Paul-Gauthier Noe, Sneha Das

Most recent speech privacy efforts have focused on anonymizing acoustic speaker attributes but there has not been as much research into protecting information from speech content.

On Crowdsourcing-design with Comparison Category Rating for Evaluating Speech Enhancement Algorithms

no code implementations2 Jun 2023 Angélica S. Z. Suárez, Clément Laroche, Line H. Clemmensen, Sneha Das

The evaluation of such algorithms often relies on reference-based objective metrics that are shown to correlate poorly with human perception.

Pre-processing Blood-Volume-Pulse for In-the-wild Applications

no code implementations27 Apr 2023 Laurits Fromberg, Sneha Das, Line Katrine Harder Clemmensen

Our method achieves better results for most time features as well as for a subset of the frequency features.

Computational behavior recognition in child and adolescent psychiatry: A statistical and machine learning analysis plan

no code implementations11 May 2022 Nicole N. Lønfeldt, Flavia D. Frumosu, A. -R. Cecilie Mora-Jensen, Nicklas Leander Lund, Sneha Das, A. Katrine Pagsberg, Line K. H. Clemmensen

Features from the videos will be extracted and used to compute ratings of behavior, which will be compared to ratings of behavior produced by mental health professionals trained to use a specific behavioral coding manual.

Speech Detection For Child-Clinician Conversations In Danish For Low-Resource In-The-Wild Conditions: A Case Study

no code implementations25 Apr 2022 Sneha Das, Nicole Nadine Lønfeldt, Anne Katrine Pagsberg, Line. H. Clemmensen

Through our work in this paper, we learned that the model with default classification threshold performs worse on children from the patient group.

Continuous Metric Learning For Transferable Speech Emotion Recognition and Embedding Across Low-resource Languages

no code implementations28 Mar 2022 Sneha Das, Nicklas Leander Lund, Nicole Nadine Lønfeldt, Anne Katrine Pagsberg, Line H. Clemmensen

Furthermore, to address the lack of activation and valence labels in the transfer datasets, we annotate the signal samples with activation and valence levels corresponding to a dimensional model of emotions, which were then used to evaluate the quality of the embedding over the transfer datasets.

Towards Transferable Speech Emotion Representation: On loss functions for cross-lingual latent representations

no code implementations28 Mar 2022 Sneha Das, Nicole Nadine Lønfeldt, Anne Katrine Pagsberg, Line H. Clemmensen

We show that while the DAE has the highest classification accuracy among the methods, the semi-supervised VAE has a comparable classification accuracy and a more consistent latent embedding distribution over data sets.

Towards Interpretable and Transferable Speech Emotion Recognition: Latent Representation Based Analysis of Features, Methods and Corpora

no code implementations5 May 2021 Sneha Das, Nicole Nadine Lønfeldt, Anne Katrine Pagsberg, Line H. Clemmensen

Furthermore, due to the black-box nature of deep learning algorithms, a newer challenge is the lack of interpretation and transparency in the models and the decision making process.
