Building naturalistic emotionally balanced speech corpus by retrieving emotional speech from existing podcast recordings

R Lotfian, C Busso - IEEE Transactions on Affective Computing, 2017 - ieeexplore.ieee.org
The lack of a large, natural emotional database is one of the key barriers to translate results
on speech emotion recognition in controlled conditions into real-life applications. Collecting …

Curriculum learning for speech emotion recognition from crowdsourced labels

R Lotfian, C Busso - IEEE/ACM Transactions on Audio, Speech …, 2019 - ieeexplore.ieee.org
This study introduces a method to design a curriculum for machine-learning to maximize the
efficiency during the training process of deep neural networks (DNNs) for speech emotion …

Predicting categorical emotions by jointly learning primary and secondary emotions through multitask learning

R Lotfian, C Busso - Interspeech 2018, 2018 - par.nsf.gov
Detection of human emotions is an essential part of affect-aware human-computer

collected during natural conversations. Recording natural interactions through telephone is …

[PDF][PDF] Gender De-Biasing in Speech Emotion Recognition.

C Gorrostieta, R Lotfian, K Taylor, R Brutti, J Kane - Interspeech, 2019 - isca-archive.org
Abstract Machine learning can unintentionally encode and amplify negative bias and
stereotypes present in humans, be they conscious or unconscious. This has led to high …

Formulating emotion perception as a probabilistic model with application to categorical emotion classification

R Lotfian, C Busso - 2017 Seventh International Conference on …, 2017 - ieeexplore.ieee.org
Automatic recognition of emotions is an important part of affect-sensitive human-computer
interaction (HCI). Expressive behaviors tend to be ambiguous with blended emotions during …

Practical considerations on the use of preference learning for ranking emotional speech

R Lotfian, C Busso - 2016 IEEE International Conference on …, 2016 - ieeexplore.ieee.org
A speech emotion retrieval system aims to detect a subset of data with specific expressive
content. Preference learning represents an appealing framework to rank speech samples in …

[PDF][PDF] Retrieving Categorical Emotions Using a Probabilistic Framework to Define Preference Learning Samples.

R Lotfian, C Busso - Interspeech, 2016 - ecs.utdallas.edu
Preference learning is an appealing approach for affective recognition. Instead of predicting
the underlying emotional class of a sample, this framework relies on pairwise comparisons …
