Dear Colleagues, We are pleased to announce that our proposed special session "Analysis of mouth motion for speech recognition and speaker verification" has been accepted by the 11th IEEE International Conference on Face and Gesture Recognition (FG'15) www.fg2015.org and would like to invite you to contribute to it. The session addresses the importance of analyzing human mouth motion for human-computer interaction and includes, but not limited to, the following five main topics: 1) visual speech recognition 2) audiovisual speech recognition 3) visual-only speaker verification 4) audio/visual fusion for speaker verification and liveness detection 5) mouth non-manuals for automatic sign language recognition The deadline for paper submission is the 24th of November and you may submit your paper through the CMT system under the shortened name "Special Session on Mouth Motion Analysis". The CMT is available from here: https://cmt.research.microsoft.com/FG2015 We are looking forward to your papers and would like to thank you in advance for your support. Best regards, Dr. Ziheng Zhou, University of Oulu Prof. Guoying Zhao, University of Oulu Dr. Stefanos Zafeiriou, Imperial College London
