Audio-Visual Speech Recognition With A Hybrid CTC/Attention Architecture
Stavros Petridis, Themos Stafylakis, Pingchuan Ma +2
Recent works in speech recognition rely either on connectionist temporal classification (CTC) or sequence-to-sequence models for character-level recognition. CTC assumes conditiona…
Transfer Learning for Action Unit Recognition
Yen Khye Lim, Zukang Liao, Stavros Petridis +1
This paper presents a classifier ensemble for Facial Expression Recognition (FER) based on models derived from transfer learning. The main experimentation work is conducted for fac…
End-to-End Speech-Driven Facial Animation with Temporal GANs
Konstantinos Vougioukas, Stavros Petridis, Maja Pantic
Speech-driven facial animation is the process which uses speech signals to automatically synthesize a talking character. The majority of work in this domain creates a mapping from…
A real-time and unsupervised face Re-Identification system for Human-Robot Interaction
Yujiang Wang, Jie Shen, Stavros Petridis +1
In the context of Human-Robot Interaction (HRI), face Re-Identification (face Re-ID) aims to verify if certain detected faces have already been observed by robots. The ability of d…
End-to-end Audiovisual Speech Recognition
Stavros Petridis, Themos Stafylakis, Pingchuan Ma +3
Several end-to-end deep learning approaches have been recently presented which extract either audio or visual features from the input images or audio signals and perform speech rec…
Visual-Only Recognition of Normal, Whispered and Silent Speech
Stavros Petridis, Jie Shen, Doruk Cetin +1
Silent speech interfaces have been recently proposed as a way to enable communication when the acoustic signal is not available. This introduces the need to build visual speech rec…
