Is “Hi… Kia…” sufficient to express sad mood? Yes. Deep learning driven investigation by Youngwoo and Taesu


Youngwoo Kim, an undergraduate intern has presented a paper entitled, “Hi, Kia, HI… Kia…, HI, KIA!” at the 2020 Fall Conference of Korea Society for Emotion and Sensibility. This study investigated the affective quality from the Wake-Up Words(WUW) in a passenger car. Having collaborated with Kia Design Center, Color lab has carried out a series of experiments that involved voice collection, data acquisition, and analysis with a deep learning algorithm. The study facilitated the BLSTM method based on the training with “EmoDB” dataset. The result demonstrated the potential of WUW for the in-car AI system to catch the passenger’s mood. Taesu Kim was the co-author and delivered an oral presentation.
