Self-Supervised Speaker Verification with Simple Siamese Network and Self-Supervised Regularization

no code implementations8 Dec 2021 Mufan Sang, Haoqi Li, Fang Liu, Andrew O. Arnold, Li Wan

With our strong online data augmentation strategy, the proposed SSReg shows the potential of self-supervised learning without using negative pairs and it can significantly improve the performance of self-supervised speaker representation learning with a simple Siamese network architecture.

Acted vs. Improvised: Domain Adaptation for Elicitation Approaches in Audio-Visual Emotion Recognition

no code implementations5 Apr 2021 Haoqi Li, Yelin Kim, Cheng-Hao Kuo, Shrikanth Narayanan

Key challenges in developing generalized automatic emotion recognition systems include scarcity of labeled data and lack of gold-standard references.

Unsupervised Speech Representation Learning for Behavior Modeling using Triplet Enhanced Contextualized Networks

no code implementations1 Apr 2021 Haoqi Li, Brian Baucom, Shrikanth Narayanan, Panayiotis Georgiou

In this paper, we exploit the stationary properties of human behavior within an interaction and present a representation learning method to capture behavioral information from speech in an unsupervised way.

Speaker-invariant Affective Representation Learning via Adversarial Training

no code implementations4 Nov 2019 Haoqi Li, Ming Tu, Jing Huang, Shrikanth Narayanan, Panayiotis Georgiou

In this paper, we propose a machine learning framework to obtain speech emotion representations by limiting the effect of speaker variability in the speech signals.

Linking emotions to behaviors through deep transfer learning

1 code implementation8 Oct 2019 Haoqi Li, Brian Baucom, Panayiotis Georgiou

Further, we investigate the importance of emotional-context in the expression of behavior by constraining (or not) the neural networks' contextual view of the data.

Predicting Behavior in Cancer-Afflicted Patient and Spouse Interactions using Speech and Language

no code implementations2 Aug 2019 Sandeep Nallan Chakravarthula, Haoqi Li, Shao-Yen Tseng, Maija Reblin, Panayiotis Georgiou

Cancer impacts the quality of life of those diagnosed as well as their spouse caregivers, in addition to potentially influencing their day-to-day behaviors.

Learning from Past Mistakes: Improving Automatic Speech Recognition Output via Noisy-Clean Phrase Context Modeling

1 code implementation7 Feb 2018 Prashanth Gurunath Shivakumar, Haoqi Li, Kevin Knight, Panayiotis Georgiou

In this work we model ASR as a phrase-based noisy transformation channel and propose an error correction system that can learn from the aggregate errors of all the independent modules constituting the ASR and attempt to invert those.

Unsupervised Latent Behavior Manifold Learning from Acoustic Features: audio2behavior

no code implementations12 Jan 2017 Haoqi Li, Brian Baucom, Panayiotis Georgiou

Behavioral annotation using signal processing and machine learning is highly dependent on training data and manual annotations of behavioral labels.
