<br/>   abstract  = {Enabling a natural (human-like) spoken conversation with technical systems requires affective information, contained in spoken language, to be intelligibly transmitted. This study investigates the role of speech and music codecs for affect intelligibility. A decoding and encoding of affective speech was employed from the well-known EMO-DB corpus. Using four state-of-the-art acoustic codecs and different bit-rates, the spectral error and the human affect recognition ability in labeling experiments were investigated and set in relation to results of automatic recognition of base emotions. Through this approach, the general affect intelligibility as well as the emotion specific intelligibility was analyzed. Considering the results of the conducted automatic recognition experiments, the SPEEX codec configuration with a bit-rate of 6.6 kbit/s is recommended to achieve a high compression and overall good UARs for all emotions.},
