Enhancing In-the-Wild Speech Emotion Conversion with Resynthesis-based Duration Modeling

Navin Raj Prabhu, Danilo de Oliveira, Nale Lehmann-Willenbrock +1

Speech Emotion Conversion aims to modify the emotion expressed in input speech while preserving lexical content and speaker identity. Recently, generative modeling approaches have…

Dynamics of Collective Group Affect: Group-level Annotations and the Multimodal Modeling of Convergence and Divergence

Navin Raj Prabhu, Maria Tsfasman, Catharine Oertel +2

Collaborating in a group, whether face-to-face or virtually, involves continuously expressing emotions and interpreting those of other group members. Therefore, understanding group…

EMOCONV-DIFF: Diffusion-based Speech Emotion Conversion for Non-parallel and In-the-wild Data

Navin Raj Prabhu, Bunlong Lay, Simon Welker +2

Speech emotion conversion is the task of converting the expressed emotion of a spoken utterance to a target emotion while preserving the lexical content and speaker identity. While…

In-the-wild Speech Emotion Conversion Using Disentangled Self-Supervised Representations and Neural Vocoder-based Resynthesis

Navin Raj Prabhu, Nale Lehmann-Willenbrock, Timo Gerkmann

Speech emotion conversion aims to convert the expressed emotion of a spoken utterance to a target emotion while preserving the lexical information and the speaker's identity. In th…

Leveraging Semantic Information for Efficient Self-Supervised Emotion Recognition with Audio-Textual Distilled Models

Danilo de Oliveira, Navin Raj Prabhu, Timo Gerkmann

In large part due to their implicit semantic modeling, self-supervised learning (SSL) methods have significantly increased the performance of valence recognition in speech emotion…

End-to-End Label Uncertainty Modeling in Speech Emotion Recognition using Bayesian Neural Networks and Label Distribution Learning

Navin Raj Prabhu, Nale Lehmann-Willenbrock, Timo Gerkman

To train machine learning algorithms to predict emotional expressions in terms of arousal and valence, annotated datasets are needed. However, as different people perceive others'…

Label Uncertainty Modeling and Prediction for Speech Emotion Recognition using t-Distributions

Navin Raj Prabhu, Nale Lehmann-Willenbrock, Timo Gerkmann

As different people perceive others' emotional expressions differently, their annotation in terms of arousal and valence are per se subjective. To address this, these emotion annot…

Perceived Conversation Quality in Spontaneous Interactions

Chirag Raman, Navin Raj Prabhu, Hayley Hung

The quality of daily spontaneous conversations is of importance towards both our well-being as well as the development of interactive social agents. Prior research directly studyin…

End-To-End Label Uncertainty Modeling for Speech-based Arousal Recognition Using Bayesian Neural Networks

Navin Raj Prabhu, Guillaume Carbajal, Nale Lehmann-Willenbrock +1

Emotions are subjective constructs. Recent end-to-end speech emotion recognition systems are typically agnostic to the subjective nature of emotions, despite their state-of-the-art…

Defining and Quantifying Conversation Quality in Spontaneous Interactions

Navin Raj Prabhu, Chirag Raman, Hayley Hung

Social interactions in general are multifaceted and there exists a wide set of factors and events that influence them. In this paper, we quantify social interactions with a holisti…
