A Diffeomorphic Flow-based Variational Framework for Multi-speaker Emotion Conversion

Ravi Shankar, Hsi-Wei Hsieh, Nicolas Charon +1

This paper introduces a new framework for non-parallel emotion conversion in speech. Our framework is based on two key contributions. First, we propose a stochastic version of the…

A Comparative Study of Data Augmentation Techniques for Deep Learning Based Emotion Recognition

Ravi Shankar, Abdouh Harouna Kenfack, Arjun Somayazulu +1

Automated emotion recognition in speech is a long-standing problem. While early work on emotion recognition relied on hand-crafted features and simple classifiers, the field has no…

A Deep-Bayesian Framework for Adaptive Speech Duration Modification

Ravi Shankar, Archana Venkataraman

We propose the first method to adaptively modify the duration of a given speech signal. Our approach uses a Bayesian framework to define a latent attention map that links frames of…

Multi-speaker Emotion Conversion via Latent Variable Regularization and a Chained Encoder-Decoder-Predictor Network

Ravi Shankar, Hsi-Wei Hsieh, Nicolas Charon +1

We propose a novel method for emotion conversion in speech based on a chained encoder-decoder-predictor neural network architecture. The encoder constructs a latent embedding of th…

Non-parallel Emotion Conversion using a Deep-Generative Hybrid Network and an Adversarial Pair Discriminator

Ravi Shankar, Jacob Sager, Archana Venkataraman

We introduce a novel method for emotion conversion in speech that does not require parallel training data. Our approach loosely relies on a cycle-GAN schema to minimize the reconst…
