Audio Sentiment Analysis by Heterogeneous Signal Features Learned from Utterance-Based Parallel Neural Network

BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:

@Booklet{EasyChair:668,
  author = {Ziqian Luo and Hua Xu and Feiyang Chen},
  title = {Audio Sentiment Analysis by Heterogeneous Signal Features Learned from Utterance-Based Parallel Neural Network},
  howpublished = {EasyChair Preprint no. 668},
  doi = {10.29007/7mhj},
  year = {EasyChair, 2018}}
