Synchronization rules for HMM-based audio-visual laughter synthesis
Hüseyin Çakmak, Jérôme Urbain, Thierry Dutoit
Abstract
In this paper we propose synchronization rules between acoustic and visual laughter synthesis systems. This work follows up our previous studies on acoustics laughter synthesis and visual laughter synthesis. The need of synchronization rules comes from the constraint that in laughter, HMM-based synthesis of laughter cannot be performed using a unified system where common transcriptions may be used. Therefore acoustic and visual models are trained independently without any synchronization constraints. In this work, we propose simple rules derived from the analysis of audio and visual laughter transcriptions in order to generate visual laughter transcriptions starting from acoustic transcriptions. A perceptive Mean Opinion Score (MOS) test is conducted to evaluate the method.
