Abstract
The availability of fast computers and recent software developments does not only enable us to carry out complex digital speech analysis procedures on an everyday basis, it also allows us to analyze visual information of the communication act by processing annotated digital video data. This study presents a selection of computer tools with which an editing and analysis process of computer readable video data for communication research can be carried out on different levels. A demonstration of the software tools will be given on an example of a project work currently
carried out by the author to study the influence of moods on speech and gestures.
