Availability of the component: Reference contacts are Thurid Vogt and Elisabeth AndrÃ© of University of Augsburg.
Notes: EmoVoice as toolbox for SSI is now available freely for download under the GNU Public Licences. All information on how to download EmoVoice are provided here A registration prior to the download is necessary. Combination of EmoVoice with SSI, includes modules for database creation; feature extraction + classifier building and testing; online recognition. Currently, there is no classifier or training data provided with EmoVoice: to create an own classifier based on self-recorded emotional speech corpus the SSI/ModelUI is also needed. The SSI Framework is a prerequisite to change or to recompile EmoVoice. Both the framework and ModelUI can be obtained from here.
Recently integrated into Smart Sensor Integration CALLAS toolkit, the component comes with a graphical user interface to record an emotional database reference for training a classifier tailored to a specific task: see also dedicated page
Besides functional tests, extensive experimentation in CALLAS is done in Scientific Showcases:
- the e-Tree : in this Augmented Reality art installation the component is used to derive emotional valence and arousal recognised from voice.
- the CommonTouch : the component is trained for affective input with a small group of users interacting and speaking in native French language as a preparation for an exhibition in Paris.
- for Interactive Digital Theater: in the Galaxies the component detects neutral, positive and negative emotions of people to influence the aestethic of the galaxies projected on the stage.
- for edutainment: in the Musickiosk the component is used in conjunction with a customised dictionary (Italian, French and English) for the words selected for the kiosk
